2021-11-23phy: qcom: Introduce new eDP PHY driverBjorn Andersson
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.

2020-09-28phy: qcom-qmp: Add support for DP in USB3+DP combo phyStephen Boyd
Add support for the USB3 + DisplayPort (DP) "combo" phy to the qmp phy driver. We already have support for the USB3 part of the combo phy, so most additions are for the DP phy. Split up the qcom_qmp_phy{enable,disable}() functions into the phy init, power on, power off, and exit functions that the common phy framework expects so that the DP phy can add even more phy ops like phy_calibrate() and phy_configure(). This allows us to initialize the DP PHY and configure the AUX channel before powering on the PHY at the link rate that was negotiated during link training. The general design is as follows: 1) DP controller calls phy_init() to initialize the PHY and configure the dp_com register region. 2) DP controller calls phy_configure() to tune the link rate and voltage swing and pre-emphasis settings. 3) DP controller calls phy_power_on() to enable the PLL and power on the phy. 4) DP controller calls phy_configure() again to tune the voltage swing and pre-emphasis settings determind during link training. 5) DP controller calls phy_calibrate() some number of times to change the aux settings if the aux channel times out during link training. 6) DP controller calls phy_power_off() if the link rate is to be changed and goes back to step 2 to try again at a different link rate. 5) DP controller calls phy_power_off() and then phy_exit() to power down the PHY when it is done. The DP PHY contains a PLL that is different from the one used for the USB3 PHY. Instead of a pipe clk there is a link clk and a pixel clk output from the DP PLL after going through various dividers. Introduce clk ops for these two clks that just tell the child clks what the frequency of the pixel and link are. When the phy link rate is configured we call clk_set_rate() to update the child clks in the display clk controller on what rate is in use. The clk frequencies always differ based on the link rate (i.e. 1.6Gb/s 2.7Gb/s, 5.4Gb/s, or 8.1Gb/s corresponding to various transmission modes like HBR1, HBR2 or HBR3) so we simply store the link rate and use that to calculate the clk frequencies. The PLL enable sequence is a little different from other QMP phy PLLs so we power on the PLL in qcom_qmp_phy_configure_dp_phy() that gets called from phy_power_on(). This should probably be split out better so that each phy has a way to run the final PLL/PHY enable sequence. This code is based on a submission of this phy and PLL in the drm subsystem.

2020-08-23phy: qcom-qmp: Use correct values for ipq8074 PCIe Gen2 PHY initSivaprakash Murugesan
There were some problem in ipq8074 Gen2 PCIe phy init sequence. 1. Few register values were wrongly updated in the phy init sequence. 2. The register QSERDES_RX_SIGDET_CNTRL is a RX tuning parameter register which is added in serdes table causing the wrong register was getting updated. 3. Clocks and resets were not added in the phy init. Fix these to make Gen2 PCIe port on ipq8074 devices to work.
