Subject: [PATCH v2 0/5] clock: imx95: Add LVDS/DISPLAY CSR for i.MX94

Similar to i.MX95, i.MX94 also has LVDS/DISPLAY CSR to provide
clock gate for LVDS and DISPLAY Controller. So following same approach
to add the support, as what have been done for i.MX95.

Patch 1 is to add the binding doc.
Patch 2 and 3 are fixes when supporting i.MX94, but the issues are
also exposed to i.MX95 even not triggered. No need to rush the
two patches for 6.16.
Patch 4 and 5 is to add the clk driver. Patch 4 is almost picked from
NXP downstream with a minor update. Patch 5 is modified from NXP
downstream with a few minor patches merged and updated.
Patch 6 is the dts part to give reviewer a whole view on how it is used.

Thanks for Frank Li helping do NXP internal review for the patchset.

Changes in v2:
- Correct compatible string order in patch 1 which add dt-binding
- Sort the order of of_device_id in patch 4 which add i.MX94 driver
- Update ldb pll div7 node name in patch 5 which add dts nodes
- Link to v1: https://lore.kernel.org/r/20250701-imx95-blk-ctl-7-1-v1-0-00db23bd8876@nxp.com
