[PATCH v2 0/5] media: qcom: camss: Add SM8150 CAMSS support

[Andrew Gigena via B4 Relay]

This series adds SoC-level CAMSS support for the Qualcomm SM8150
(Snapdragon 855), based on v7.4-rc1.

SM8150 contains four CSIPHY, four CSID (two full and two lite), two
VFE and two VFE-Lite instances. The blocks are close to the existing
SDM845/SM8250/SC8280XP implementations, so the driver change only adds
platform data and hooks the SoC into the existing Gen2 CSIPHY, Gen2
CSID and VFE 17x code paths. No new register programming sequences are
introduced.

The series documents the SM8150 CCI compatible, which the CCI nodes use
with qcom,msm8996-cci as the fallback. The patches are ordered bindings
first, then driver data, then the DT description. The series is
intentionally SoC-level only: it does not add a board DTS, camera
sensor drivers, or board-specific camera wiring.

Testing: with a local Pixel 4 (google-flame) board port and
out-of-tree IMX363, IMX481 and IMX520 sensor drivers, the rear wide
(IMX363) and rear tele (IMX481) cameras stream, and the front (IMX520)
path has produced frames. The board port itself is not part of this
series.

checkpatch reports no errors. The only warning is the new-binding
"MAINTAINERS needs updating" prompt, which is a false positive because
the existing CAMSS entry already covers qcom,*camss* bindings.

Changes in v2:
- Address the review comments from Sashiko, Bryan and Val.
- Drop the internal CAMCC *_src clocks from the binding, the example and
  the DTS; the binding now lists 27 clocks instead of 42.
- Remove clock-lanes from the CSI endpoints and use an unnumbered
  endpoint in the example, matching the other CAMSS bindings.
- Describe vdda-phy-supply as 0.88V and vdda-pll-supply as 1.2V.
- Move the CSIPHY supplies from the CSID resources to the CSIPHY
  resources, so they are enabled before the PHY is accessed.
- Add a separate fix for the VFE lite clock rates
- Tidy the CAMSS_8150 switch ordering.
