i.MX95's several MIXes has BLK CTL module which could be used for
clk settings, QoS settings, Misc settings for a MIX. This patchset
is to add the clk feature support, including dt-bindings

Changes in v6:
- Put the header as 1st patch, and drop the macro that counting the clks
- Add R-b for patch 2&3
- Drop of_match_ptr in patch 4
- Link to v5: https://lore.kernel.org/r/[email protected]
Changes in v5:
- Merge bindings except the one has mux-controller
- Separate clock ID headers in a separate patch per Rob's comments
- Link to v4: https://lore.kernel.org/r/[email protected]
Changes in v4:
- Separate binding doc for each modules, I still keep the syscon as node
name, because the module is not just for clock
- Pass dt-schema check
- Update node compatibles
- Link to v3: https://lore.kernel.org/r/[email protected]
Changes in v3:
- Correct example node compatible string
- Pass "make ARCH=arm64 DT_CHECKER_FLAGS=-m -j32 dt_binding_check"
- Link to v2: https://lore.kernel.org/r/[email protected]
Changes in v2:
- Correct example node compatible string
- Link to v1: https://lore.kernel.org/r/[email protected]

2.37.1
From: Peng Fan <[email protected]>
i.MX95 includes BLK CTL module in several MIXes, such as VPU_CSR in
VPUMIX, CAMERA_CSR in CAMERAMIX and etc.
The BLK CTL module is used for various settings of a specific MIX, such
as clock, QoS and etc.
This patch is to add some BLK CTL modules that has clock features.
