Hi,
This patch-set adds support for the i.MX94 Display Control Interface.
It depends on Peng Fan's DTS patch [1] that was not yet merged. Also, it
needs the BLK CTL changes [2] that I spinned off from v2 in a different
patchset.
Also, included in the patch-set are a few extra patches that the DCIF
driver depends on for functioning properly:
* 1/9 - 3/9 : add support for i.MX94 to fsl-ldb driver. It also
contains a patch (2/9) from Liu Ying that was already reviewed
and was part of another patch-set ([3]), but was never merged;
v3:
* Removed the BLK CTL patches and created a separate patch set [2] for them;
* Collected r-b tags for 1/9, 2/9, 3/9 and 9/9;
* Removed the DCIF QoS functionality until I find a better way to
implement it through syscon. QoS functionality will be added in
subsequent patches. Also, used devm_clk_bulk_get_all() and used
dev_err_probe() as suggested;
* Addressed Frank's and Krzysztof's comments on the DCIF bindings;
* Addressed Frank's comments on dtsi and dts files;
* Added a new binding patch, 6/9, for adding 'ldb' optional property to
nxp,imx95-blk-ctl.yaml;
v2:
* reworked the BLK_CTL patch and split in 2 to make it easier for
review;
* split the dts and dtsi patch in 2 separate ones;
* addressed Frank's comments in DCIF driver;
* addressed Rob's comments for the bindings files;
* addressed a couple of checkpatch issues;
Thanks,
Laurentiu
