[Freedreno] [PATCH v2 00/15] drm/msm/hdmi & phy: use generic PHY framework

[Dmitry Baryshkov]

The MSM HDMI PHYs have been using the ad-hoc approach / API instead of
using the generic API framework. Move all the PHYs to
drivers/phy/qualcomm and rework them to use generic PHY framework. This
way all the QMP-related code is kept close. Also in future this will
allow us to use a common set of functions to setup msm8974 HDMI PHY,
28nm DSI PHY and apq8964 SATA PHY (which all use UNI PLL internally).

This also causes some design changes. Currently on msm8996 the HDMI PLL
implements clock's set_rate(), while other HDMI PHY drivers used the
ad-hoc PHY API for setting the PLL rate (this includes in-tree msm8960
driver and posted, but not merged, msm8974 driver). This might result in
the PLL being set to one rate, while the rest of the PHY being tuned to
work at another rate. Adopt the latter idea and always use
phy_configure() to tune the PHY and set the PLL rate.

Changes since v1:
- Changed msm8960 / apq8064 to calculate register data instead of using
  fixed tables. This extends the list of supported modes.
  (Implementation is based on mdss-hdmi-pll-28lpm.c from msm-4.14).

- Fixed the reprogramming of PLL rate on apq8064.

- Merged all non-QMP HDMI PHY drivers into a common PHY_QCOM_HDMI
  driver (suggested by Rob Clark)

Dmitry Baryshkov (14):
  phy: qualcomm: add QMP HDMI PHY driver
  phy: qcom: apq8064-sata: extract UNI PLL register defines
  phy: qcom-uniphy: add more registers from display PHYs
  phy: qualcomm: add legacy HDMI PHY driver
  phy: qualcomm: add MSM8974 HDMI PHY support
  phy: qualcomm: add MSM8x60 HDMI PHY support
  drm/msm/hdmi: move the alt_iface clock to the hpd list
  drm/msm/hdmi: simplify extp clock handling
  drm/msm/hdmi: correct indentation of HDMI bridge functions
  drm/msm/hdmi: switch to atomic_pre_enable/post_disable
  drm/msm/hdmi: set infoframes on all pre_enable calls
  drm/msm/hdmi: pair msm_hdmi_phy_powerup with msm_hdmi_phy_powerdown
  drm/msm/hdmi: switch to generic PHY subsystem
  drm/msm/hdmi: drop old HDMI PHY code
