[PATCH v5 00/22] media: platform: rzg2l-cru: CSI-2 and CRU enhancements

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Hi All,

This patch series aims to add the below:
- Retrieve virtual channel from remote subdev
- Support to capture 8bit Bayer formats.

v4->v5
- Updated .link_validate function to drop local variable, invalid
  format check and input/output code fmt check
- Split up patch 10/17 from v4 into multiple patches (10/11/12/13/14/15)/22

v3->v4
- Added {} in rzg2l_cru_ip_format_to_fmt() for the for loop (in patch 10/17)
- Added checks for formats in .link_validate callback (in patch 13/17)
- Got rid of icndmr local variable in rzg2l_cru_initialize_image_conv()
 (in patch 15/17)
- Moved macro ICnDMR_YCMODE_UYVY to rzg2l-cru-regs.h
- Included RB tags from Laurent for patches 15 and 17

v2->v3
- Added MUST_CONNECT flag for source pads
- Used ARRAY_SIZE() instead of NR_OF_RZG2L_CSI2_PAD
- Implemented rzg2l_cru_ip_format_to_fmt() and rzg2l_cru_ip_index_to_fmt()
- Dropped checking fmt in rzg2l_cru_initialize_image_conv()
- Dropped fse->index checks
- Implemented link_validate for video node
- Re-used rzg2l_cru_ip_format_to_fmt() to fetch icndmr details
- Moved register definitions to separate header file
- Updated subject lines and commit messages
- Collected RB tag

v1->v2
- Fixed retrieving VC from subdev
- Fixed review comments pointed by Laurent
  * Refactored supported CRU formats
  * Added MUST_CONNECT flag wherever required
  * Dropped `channel` member from `struct

v1:
