Uwe Kleine-König 54234e3a69 phy: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/phy/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

Krzysztof Kozlowski 00ca8a15da phy: constify of_phandle_args in xlate
The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args.  Make the argument
pointer to const for code safety and readability.

Rob Herring 7559e7572c phy: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Uwe Kleine-König f1c01b91e5 phy: renesas: r8a779f0-ether-serdes: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Add r8a779f0_eth_serdes_power_on() to initialize the hardware for
each channel from the step 9 or later on the datasheet. In other words,
the procedure from the step 1 to 8 is for all channel and it is needed
once only. So, the .init() in any channel instance is called, this
driver initializes the hardware from step 1 to 8. And then, .power_on()
is called, this driver initializes the hardware from step 9 or later.

Add Renesas Ethernet SERDES driver for R-Car S4-8 (r8a779f0).
The datasheet describes initialization procedure without any information
about registers' name/bits. So, this is all black magic to initialize
the hardware. Especially, all channels should be initialized at once.
