Current multiplier (60) results in CPU getting the rate which is
unlisted in the CPU frequency tables (60 * 19.2 = 1152 MHz). This
results in warnings from the cpufreq during startup.
Change PLL programming (l = 54) to init CPU clocks to start with the
frequency of 54 * 19.2 = 1036.8 MHz which is supported by both power and
performance clusters from all speed bins.

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names. Use parent_hws where possible to refer parent
clocks directly, skipping the lookup.
Note, the system names for xo clocks were changed from "xo" to
"xo_board" to follow the example of other platforms. This switches the
clocks to use DT-provided "xo_board" clock instead of manually
registered "xo" clock and allows us to drop qcom_cc_register_board_clk()
call from the driver at some point.
In the same way change the looked up system "sleep_clk_src" clock to
"sleep_clk", which is registered from DT.

For each of XO_BUFFER_PINCTRL clocks there is a corresponding XO_BUFFER clock
with the similar name (e.g. msm8998_ln_bb_clk3_pin vs
msm8998_ln_bb_clk3). For qcs404_ln_bb_clk_pin there is no
qcs404_ln_bb_clk, since the msm8992_ln_bb_clk was used instead (even for
qcs404 platform).
Follow the usual practice and rename msm8992_ln_bb_clk clocks to
qcs404_ln_bb_clk (and rename active-only clock in a similar way).
This is a preparation step for the next patch, which will merge
XO_BUFFER and XO_BUFFER_PINCTRL definitions.

GP_CLK_{1-3}{A, B} : GPIO_{49-51, 97, 12, 13} (Belongs to GCC itself)
GP_MN : GPIO_110 (Doesn't seem to be described in gcc,

Those clocks may be used as e.g. PWM sources for external peripherals.
Add more frequencies to the table for those clocks so it's possible
for arbitrary peripherals to make use of them.

It appears that having only .name populated in parent_data for clocks
which are only globally searchable currently will not work as the clk core
won't copy that name if there is no .fw_name present as well.
So, populate .fw_name for all parent clocks in parent_data.

Some bootloader may leave the system in an even more undefined state
with the secondary mux of L2 or other cores sourcing out of the acpu_aux
parent. This results in the clk set to the PXO rate or a PLL8 rate.
The current logic to reset the mux and set them to a defined state only
handle if the mux are configured to source out of QSB. Change this and
force a new and defined state if the current clk is lower than the aux
rate. This way we can handle any wrong configuration where the mux is
sourcing out of QSB (rate 225MHz, currently set to a virtual rate of 1),
PXO rate (rate 25MHz) or PLL8 (needs to be configured to run at 384Mhz).

The secondary mux parent order is swapped.
This currently doesn't cause problems as the secondary mux is used for idle
clk and as a safe clk source while reprogramming the hfpll.
Each mux have 2 or more output but he always have a safe source to
switch while reprogramming the connected pll. We use a clk notifier to
switch to the correct parent before clk core can apply the correct rate.
The parent to switch is hardcoded in the mux struct.
For the secondary mux the safe source to use is the qsb parent as it's
the only fixed clk as the acpus_aux is a pll that can source from pxo or
from pll8.
The hardcoded safe parent for the secondary mux is set to index 0 that
in the secondary mux map is set to 2.
But the index 0 is actually acpu_aux in the parent list.
Fix the swapped parents to correctly handle idle frequency and output a
sane clk_summary report.

This patch adds the support for giving the complete bitmask
in reset structure and reset operation will use this bitmask
for all reset operations.
Currently, reset structure only takes a single bit for each reset
and then calculates the bitmask by using the BIT() macro.
However, this is not sufficient anymore for newer SoC-s like IPQ8074,
IPQ6018 and more, since their networking resets require multiple bits
to be asserted in order to properly reset the HW block completely.
So, in order to allow asserting multiple bits add "bitmask" field to
qcom_reset_map, and then use that bitmask value if its populated in the
driver, if its not populated, then we just default to existing behaviour
and calculate the bitmask on the fly.

The pm_runtime usage in lpass-sc7280 was broken in quite a few
ways. Specifically:
1. At the end of probe it called "put" twice. This is a no-no and will
end us up with a negative usage count. Even worse than calling
"put" twice, it never called "get" once. Thus after bootup it could
be seen that the runtime usage of the devices managed by this
driver was -2.
2. In some error cases it manually called pm_runtime_disable() even
though it had previously used devm_add_action_or_reset() to set
this up to be called automatically. This meant that in these error
cases we'd double-call pm_runtime_disable().
3. It forgot to call undo pm_runtime_use_autosuspend(), which can
sometimes have subtle problems (and the docs specifically mention
that you need to undo this function).
Overall the above seriously calls into question how this driver is
working. It seems like a combination of "it doesn't", "by luck", and
"because of the weirdness of runtime_pm". Specifically I put a
printout to the serial console every time the runtime suspend/resume
was called for the two devices created by this driver (I wrapped the
pm_clk calls). When I had serial console enabled, I found that the
calls got resumed at bootup (when the clk core probed and before our
double-put) and then never touched again. That's no good.
[ 0.829997] DOUG: my_pm_clk_resume, usage=1
[ 0.835487] DOUG: my_pm_clk_resume, usage=1
When I disabled serial console (speeding up boot), I got a different
pattern, which I guess (?) is better:
[ 0.089767] DOUG: my_pm_clk_resume, usage=1
[ 0.090507] DOUG: my_pm_clk_resume, usage=1
[ 0.151885] DOUG: my_pm_clk_suspend, usage=-2

[ 1.825747] DOUG: my_pm_clk_resume, usage=-1
[ 1.825774] DOUG: my_pm_clk_resume, usage=-1
[ 1.888269] DOUG: my_pm_clk_suspend, usage=-2
[ 1.888282] DOUG: my_pm_clk_suspend, usage=-2
These different patterns have to do with the fact that the core PM
Runtime code really isn't designed to be robust to negative usage
counts and sometimes may happen to stumble upon a behavior that
happens to "work". For instance, you can see that
__pm_runtime_suspend() will treat any non-zero value (including
negative numbers) as if the device is in use.
In any case, let's fix the driver to be correct. We'll hold a
pm_runtime reference for the whole probe and then drop it (once!) at
the end. We'll get rid of manual pm_runtime_disable() calls in the
error handling. We'll also switch to devm_pm_runtime_enable(), which
magically handles undoing pm_runtime_use_autosuspend() as of commit
b4060db925 ("PM: runtime: Have devm_pm_runtime_enable() handle
pm_runtime_dont_use_autosuspend()").
While we're at this, let's also use devm_pm_clk_create() instead of
rolling it ourselves.
Note that the above changes make it obvious that
lpassaudio_create_pm_clks() was doing more than just creating
clocks. It was also setting up pm_runtime parameters. Let's rename it.
All of these problems were found by code inspection. I started looking
at this driver because it was involved in a deadlock that I reported a
while ago [1]. Though I bisected the deadlock to commit 1b771839de
("clk: qcom: gdsc: enable optional power domain support"), it was
never really clear why that patch affected it other than a luck of
timing changes. I'll also note that by fixing the timing (as done in
this change) we also seem to aboid the deadlock, which is a nice
benefit.
Also note that some of the fixes here are much the same type of stuff
that Dmitry did in commit 72cfc73f46 ("clk: qcom: use
devm_pm_runtime_enable and devm_pm_clk_create"), but I guess
lpassaudiocc-sc7280.c didn't exist then.

Second, this confuses runtime PM on CoachZ for the camera devices by
causing the camera clock controller's runtime PM usage_count to go
negative after resuming from suspend. This is because runtime PM is
being used on the clock controller while runtime PM is disabled for the
device.
The reason for the negative count is because a GDSC is represented as a
genpd and each genpd that is attached to a device is resumed during the
noirq phase of system wide suspend/resume (see the noirq suspend ops
assignment in pm_genpd_init() for more details). The camera GDSCs are
attached to camera devices with the 'power-domains' property in DT.
Every device has runtime PM disabled in the late system suspend phase
via __device_suspend_late(). Runtime PM is not usable until runtime PM
is enabled in device_resume_early(). The noirq phases run after the
'late' and before the 'early' phase of suspend/resume. When the genpds
are resumed in genpd_resume_noirq(), we call down into gdsc_enable()
that calls pm_runtime_resume_and_get() and that returns -EACCES to
indicate failure to resume because runtime PM is disabled for all
devices.
Upon closer inspection, calling runtime PM APIs like this in the GDSC
driver doesn't make sense. It was intended to make sure the GDSC for the
clock controller providing other GDSCs was enabled, specifically the
MMCX GDSC for the display clk controller on SM8250 (sm8250-dispcc), so
that GDSC register accesses succeeded. That will already happen because
we make the 'dev->pm_domain' a parent domain of each GDSC we register in
gdsc_register() via pm_genpd_add_subdomain(). When any of these GDSCs
are accessed, we'll enable the parent domain (in this specific case
MMCX).
We also remove any getting of runtime PM during registration, because
when a genpd is registered it increments the count on the parent if the
genpd itself is already enabled.

GDSCs cannot be transitioned into a Retention state in SW.
When either the RETAIN_MEM bit, or both the RETAIN_MEM and
RETAIN_PERIPH bits are set, and the GDSC is left ON, the HW
takes care of retaining the memory/logic for the domain when
the parent domain transitions to power collapse/power off state.
On some platforms where the parent domains lowest power state
itself is Retention, just leaving the GDSC in ON (without any
RETAIN_MEM/RETAIN_PERIPH bits being set) will also transition
it to Retention.
The existing logic handling the PWRSTS_RET seems to set the
RETAIN_MEM/RETAIN_PERIPH bits if the cxcs offsets are specified
but then explicitly turns the GDSC OFF as part of _gdsc_disable().
Fix that by leaving the GDSC in ON state.

The gfx3d clock is hand-crafting its own clk_rate_request in
clk_gfx3d_determine_rate to pass to the parent of that clock.
However, since the clk_rate_request is zero'd at creation, it will have
a max_rate of 0 which will break any code depending on the clock
boundaries.
That includes the recent commit 948fb0969e ("clk: Always clamp the
rounded rate") which will clamp the rate given to clk_round_rate() to
the current clock boundaries.
For the gfx3d clock, it means that since both the min_rate and max_rate
fields are set at zero, clk_round_rate() now always return 0.
Let's initialize the min_rate and max_rate fields properly for that
clock.

The USB PHY on MSM8909 works with the driver used on MSM8916
(phy-qcom-usb-hs.c). When turning the PHY on/off it is first reset
using the standard reset controller API. On MSM8916 the reset is
provided by the USB driver (ci_hdrc_msm_por_reset() in ci_hdrc_msm.c).
While this seems to work on MSM8909 as well, the Qualcomm Linux sources
suggest that the PHY should be reset using the GCC_USB2_HS_PHY_ONLY_BCR
register instead. In general this is easy to set up in the device tree,
thanks to the standard reset controller API.
However, to conform to the specifications of the PHY the reset signal
should be asserted for at least 10 us. This is handled correctly on
MSM8916 in ci_hdrc_msm_por_reset(), but not within the GCC driver.
Fix this by making use of the new "udelay" field of qcom_reset_map
and set a delay of ~15 us between the assertion/deassertion of the
USB PHY reset signal.

The amount of time required between asserting and deasserting the reset
signal can vary depending on the involved hardware component. Sometimes
1 us might not be enough and a larger delay is necessary to conform to
the specifications.
Usually this is worked around in the consuming drivers, by replacing
reset_control_reset() with a sequence of reset_control_assert(), waiting
for a custom delay, followed by reset_control_deassert().
However, in some cases the driver making use of the reset is generic and
can be used with different reset controllers. In this case the reset
time requirement is better handled directly by the reset controller
driver.
Make this possible by adding an "udelay" field to the qcom_reset_map
that allows setting a different reset delay (in microseconds).

Split and extend existing CLK_AIF_OSR_DIV macro to implement mi2s
clocks. This simplifies the driver and removes extra code duplication.
The clock mi2s_div_clk used .enable_reg/.enable_bit, however these
fields are not used with by the clk_regmap_div_ops, thus they are
silently dropped. Clock enablement is handled in the mi2s_bit_div_clk
clock.

The Snapdragon 670 adds and removes some clocks, adds new frequencies, and
adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while
also removing some GDSCs. Despite these differences, there are many
similarities with SDM670. Add data for SDM670 in the driver for SDM845 to
reuse the most of the clock data.
Advantages and disadvantages of this approach:
+ maintenance applies to both sdm670 and sdm845 by default
+ less duplicate code (clocks) means smaller distro/pre-built kernels
with all drivers enabled
- clocks for both SoC's must be compiled if the user wants clocks for one
specific SoC (both or none)
- additional testing needed for sdm845 devices

The built-in PPE engine has a dedicated clock for the EIP-197 crypto
engine.
So, since the required clock currently missing add support for it.

NSS port 5 and 6 frequency tables are currently broken and are causing a
wide ranges of issue like 1G not working at all on port 6 or port 5 being
clocked with 312 instead of 125 MHz as UNIPHY1 gets selected.
So, update the frequency tables with the ones from the downstream QCA 5.4
based kernel which has already fixed this.
