[PATCH v2 0/8] Add CAMSS support for Qualcomm Hawi and Maili

[Nihal Kumar Gupta]

Hawi and Maili are recently announced Qualcomm Snapdragon SoCs [1].
This series adds Camera Subsystem (CAMSS) support for the Qualcomm
Hawi and Maili SoC's.

[1] https://www.qualcomm.com/smartphones/products/8-series/snapdragon-8-elite-gen-6-mobile-platform

Hawi's camera hardware topology:
- 6x CSIPHY (CSI Physical Layer)
- 3x TPG (Test Pattern Generator)
- 3x CSID (CSI Decoder)
- 2x CSID Lite
- 3x VFE (Video Front End), 5 RDI per VFE
- 2x VFE Lite, 4 RDI per VFE Lite

Maili shares the same IP as Hawi. The only difference is Hawi has 6 CSIPHY
while Maili has 5.

Used following tools for the sanity check of these changes.
- make -j32 W=1
- checkpatch.pl
- make DT_CHECKER_FLAGS=-m W=1 DT_SCHEMA_FILES=i2c/qcom,i2c-cci.yaml dt_binding_check
- make DT_CHECKER_FLAGS=-m DT_SCHEMA_FILES=media/qcom,hawi-camss.yaml dt_binding_check W=1
- make CHECK_DTBS=y W=1 dtbs

Changes in v2:
- Not an RFC anymore
- Rebase on next-20261012 and drop the external CSI2 PHY series dependency. 
- Drop DTS patches; they will be posted separately with Maili DTS dependency.
- Collect Reviewed-by from Konrad, Abel, Bryan
- Split CSID and VFE 1190 into individual files rather than in separate
  combined Gen4 files - bod
- Remove reduandant is_lite condition in CAMSS CSID and VFE resources - bod
- Replace bias-pull-up and bias-pull-down with bias-disable for the
  SCL/SDA pins of CCI nodes in TLMM, as internal weak pull is inproper
  with existing board level pull up resistors - Loic
- Drop the unused reg_update_after_csid_config flag
- Add lane count fallback path for CSID RX configuration
- Add Hawi DPHY support by tuning register table, which prevents
  potential stream stalls and SMMU faults.
- Add a standalone Hawi CSI2 PHY compatible and make Maili fall back to it.
- Resolve conflicts introduced by Glymur in CSI2 PHY binding.
- Link to v1: https://lore.kernel.org/r/20260923-hawi-maili-camss-v1-0-cbbb42e534ef@oss.qualcomm.com
