2021-11-23phy: amlogic: Add a new driver for the HDMI TX PHY on Meson8/8b/8m2Martin Blumenstingl3-0/+171
Amlogic Meson8/8b/8m2 have a built-in HDMI PHY in the HHI register region. Unfortunately only few register bits are documented. For HHI_HDMI_PHY_CNTL0 the magic numbers are taken from the 3.10 vendor kernel.

This should check ">pmctrl" instead of "->sysctrl". This bug could potentially lead to a crash if we dereference the error pointer.

2021-11-23phy: qcom: Introduce new eDP PHY driverBjorn Andersson4-0/+686
Many recent Qualcomm platforms comes with native DP and eDP support. This consists of a controller in the MDSS and a QMP-like PHY. While similar to the well known QMP block, the eDP PHY only has TX lanes and the programming sequences are slightly different. Rather than continuing the trend of parameterize the QMP driver to pieces, this introduces the support as a new driver. The registration of link and pixel clocks are borrowed from the QMP driver. The non-DP link frequencies are omitted for now. The eDP PHY is very similar to the dedicated (non-USB) DP PHY, but only the prior is supported for now.
