2020-09-28phy: qcom-qmp: Add support for DP in USB3+DP combo phyStephen Boyd2-90/+775
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.

2020-09-28phy: qcom-qmp: Move 'serdes' and 'cfg' into 'struct qcom_phy'Stephen Boyd1-57/+56
The serdes I/O region is where the PLL for the phy is controlled. Sometimes the PLL is shared between multiple phys, for example in the PCIe case where there are three phys inside the same wrapper. Other times the PLL is for a single phy, i.e. some USB3 phys. To complete the trifecta we have the USB3+DP combo phy where the USB3 and DP phys each have their own serdes region because they have their own PLL while they both share a common I/O region pertaining to the USB type-c pinout and cable orientation. Let's move the serdes iomem pointer into 'struct qmp_phy' so that we can correlate PLL control to the phy that uses it. This allows us to support the USB3+DP combo phy in this driver. This isn't a problem for the 3-lane/phy PCIe phy because there is a common init function that is the only place the serdes region is programmed. Furthermore, move the configuration data that contains most of the register programming sequences to the qmp phy struct. This data isn't qmp wrapper specific. It is phy specific data used to tune various settings for things like pre-emphasis, bias, etc. Signed-off-by: Stephen Boyd <swboyd@chromium.org> Cc: Jeykumar Sankaran <jsanka@codeaurora.org> Cc: Chandan Uddaraju <chandanu@codeaurora.org> Cc: Vara Reddy <varar@codeaurora.org> Cc: Tanmay Shah <tanmay@codeaurora.org> Cc: Bjorn Andersson <bjorn.andersson@linaro.org> Cc: Manu Gautam <mgautam@codeaurora.org> Cc: Sandeep Maheswaram <sanm@codeaurora.org> Cc: Douglas Anderson <dianders@chromium.org> Cc: Sean Paul <seanpaul@chromium.org> Cc: Jonathan Marek <jonathan@marek.ca> Cc: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Cc: Rob Clark <robdclark@chromium.org> Link: https://lore.kernel.org/r/20200916231202.3637932-5-swboyd@chromium.org Signed-off-by: Vinod Koul <vkoul@kernel.org>

USB_PHY depends on USB_SUPPORT but "select" doesn't care about dependencies, so this driver should also depend on USB_SUPPORT. It should not select USB_SUPPORT.
