Currently there is a null pointer check for hdmi_phy that implies it may be null, however a dev_err messages dereferences this potential null pointer. Avoid a null pointer dereference by only emitting the dev_err message if hdmi_phy is non-null. It is a moot point if the error message needs to be printed at all, but since this is a relatively new piece of code it may be useful to keep the message in for the moment in case there are unforseen errors that need to be reported.

Update the rockchip-emmc phy to set the otapdlysec register with a dt property. This was mentioned from Brian Norris when he sent the path to set the default value in the driver. This patch add a dt property 'output-tapdelay-select' u32 and allow to set the 0x0-0xf. If not set in dts, the old default 0x4 applies. Tested with our customized rk3399 to tune the eMMC.

Exynos5420 variant of USB2 PHY is handled by the same code as the Exynos5250 one.

This driver includes the following two files directly: - mt7621.h - ralink_regs.h Compilation for its related platform properly works because its real path is included in 'arch/mips/ralink/Platform' as cflags. This driver depends on RALINK but also is enabled for COMPILE_TEST where nothing about its platform is known and this directly included files are not found at all breaking compilation. If we want 'COMPILE_TEST' we have to change cflags also inside 'phy/ralink' subdirectory Makefile which seems that does not like to linux-phy maintainers. Hence remove COMPILE_TEST from Kconfig to avoid the problem. Fixes: d87da323 ("phy: ralink: Add PHY driver for MT7621 PCIe PHY") Reported-by:

Initially this PHY driver was implementing MDIO access on its own. It was caused by lack of proper hardware design understanding. It has been changed back in 2017. DT bindings were changed and driver was updated to use MDIO layer. It should be really safe now to drop the old deprecated code. All Linux stored DT files don't use it for 3,5 year. There is close to 0 chance there is any bootloader with its own DTB using old the binding. Signed-off-by:
