2021-01-13phy: stm32: rework PLL Lock detectionAmelie Delaunay1-34/+54
USBPHYC has a register per phy to control and monitor the debug interface of the HS PHY through a digital debug access. With this register, it is possible to know if PLL Lock input to phy is high. That means the PLL is ready for HS operation. Instead of using an hard-coded delay after PLL enable and PLL disable, use this bit to ensure good operating of the HS PHY. Also use an atomic counter (n_pll_cons) to count the actual number of PLL consumers and get rid of stm32_usbphyc_has_one_phy_active. The boolean active in the usbphyc_phy structure is kept, because we need to know in remove if a phy_exit is required to properly disable the PLL.

PLL block requires to be powered with 1v1 and 1v8 supplies to catch ENABLE signal. Currently, supplies are managed through phy_ops .power_on/off, and PLL activation/deactivation is managed through phy_ops .init/exit. The sequence of phy_ops .power_on/.phy_init, .power_off/.exit is USB drivers dependent. To ensure a good behavior of the PLL, supplies have to be managed at PLL activation/deactivation. That means the supplies need to be put in usbphyc node and not in phy children nodes.

2020-12-08drm/mediatek: avoid dereferencing a null hdmi_phy on an error messageColin Ian King1-2/+3
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.
