Arm Mali-C55 ISP driver
=======================

The Arm Mali-C55 ISP driver implements a single driver-specific control:

``V4L2_CID_MALI_C55_CAPABILITIES (bitmask)``
    Detail the capabilities of the ISP by giving detail about the fitted blocks.

	:widths: 2 4 8

	* - Bit
	  - Macro
	  - Meaning
        * - 0
          - MALI_C55_PONG

        * - 3
          - MALI_C55_TEMPER
          - Temper is fitted in the ISP
        * - 4
          - MALI_C55_SINTER_LITE
          - Sinter Lite is fitted in the ISP instead of the full Sinter version

          - Iridix local tone mappine is fitted in the ISP
        * - 7
          - MALI_C55_IRIDIX_GTM
          - Iridix global tone mapping is fitted in the ISP
        * - 8
          - MALI_C55_CNR
          - Colour noise reduction is fitted in the ISP
        * - 9
          - MALI_C55_FRSCALER
          - The full resolution pipe scaler is fitted in the ISP
        * - 10
          - MALI_C55_DS_PIPE
          - The downscale pipe is fitted in the ISP

    The Mali-C55 ISP can be configured in a number of ways to include or exclude
    blocks which may not be necessary. This control provides a way for the
    driver to communicate to userspace which of the blocks are fitted in the
    design.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
