| | * phy: phy-can-transceiver: Make devm_gpiod_get optionalAswath Govindraju2021-11-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases the standby/enable gpio can be pulled low/high and would not be connected to a gpio. The current driver implementation will return an error in these cases. Therefore, make devm_gpiod_get optional.

| | * phy: qcom: Introduce new eDP PHY driverBjorn Andersson2021-11-234-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB/DP combo PHY exposes the "qmp_dp_phy_pll_link_clk" and "qmp_dp_phy_pll_vco_div_clk" clocks, that are consumed by the display clock controller. But for boards with multiple enabled QMP USB/DP combo instances the hard coded names collides - and hence only the first probed device is allowed to register. Given that clocks are no longer reference globally by name and it's possible to replace the hard coded names by something unique, but still user friendly. The two new clock names are based on dev_name() and results in names such as "88ee000.phy::link_clk" and "88ee000.phy::vco_div_clk".
