phy: rockchip: naneng-combphy: compatible reset with old DT

2025-02-04T05:12:37+00:00

The device tree of RK3568 did not specify reset-names before.
So add fallback to old behaviour to be compatible with old DT.

phy: rockchip: fix Kconfig dependency more

2025-02-04T05:12:37+00:00

A previous patch ensured that USB Type C connector support is enabled,
but it is still possible to build the phy driver without enabling
CONFIG_USB (host support) or CONFIG_USB_GADGET (device support), and
in that case the common helper functions are unavailable:

aarch64-linux-ld: drivers/phy/rockchip/phy-rockchip-usbdp.o: in function `rk_udphy_probe':
phy-rockchip-usbdp.c:(.text+0xe74): undefined reference to `usb_get_maximum_speed'

Select CONFIG_USB_COMMON directly here, like we do in some other phy
drivers, to make sure this is available even when actual USB support
is disabled or in a loadable module that cannot be reached from a
built-in phy driver.

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: rockchip-pcie: Use guard notation when acquiring mutex

2024-12-04T13:27:08+00:00

Using guard notation makes the code more compact and error handling
more robust by ensuring that mutexes are released in all code paths
when control leaves critical section.

Refactor the mutex handling in the rockchip_pcie_phy_power_on() function to
improve code readability and maintainability. The goto statement has
been removed, and the mutex_unlock call is now directly within the
conditional block.

Return the result of reset_control_deassert() or regmap_read_poll_timeout()
function, with 0 indicating success and an error code indicating failure.
