phy: rockchip: samsung-hdptx: Set drvdata before enabling runtime PM

2024-12-08T16:12:07+00:00

In some cases, rk_hdptx_phy_runtime_resume() may be invoked before
platform_set_drvdata() is executed in ->probe(), leading to a NULL
pointer dereference when using the return of dev_get_drvdata().

Ensure platform_set_drvdata() is called before devm_pm_runtime_enable().

phy: rockchip: naneng-combphy: fix phy reset

2024-12-04T14:19:08+00:00

Currently, the USB port via combophy on the RK3528/RK3588 SoC is broken.

  usb usb8-port1: Cannot enable. Maybe the USB cable is bad?

This is due to the combphy of RK3528/RK3588 SoC has multiple resets, but
only "phy resets" need assert and deassert, "apb resets" don't need.
So change the driver to only match the phy resets, which is also what
the vendor kernel does.

phy: Switch back to struct platform_driver::remove()

2024-10-17T15:03:03+00:00

After commit 0edb555a65d1 ("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.

Since some Rockchip SoCs (e.g RK3576) have more than one clock,
this converts the clock management from single to bulk method to
