Hi,

this is v3 for the LVDS support on TQMa93xx module series.

It consists of three parts:
1. New PLL configuration for 477.4 MHz
2. LVDS support for imx93
3. LVDS platform support for tqma9352-mba93xxla & tqma9352-mba93xxca

Patch 1 adds a video PLL configuration for 477.4MHz
Patch 2 is the imx93 equivalent of commit 1cb0c87d27dc ("dt-bindings:
soc: imx8mp-media-blk-ctrl: Add LDB subnode into schema and example")
Patch 3 is the imx93 equivalent of commit 9cb6d1b39a8f ("soc: imx:
imx8m-blk-ctrl: Scan subnodes and bind drivers to them")
Patch 4 is the imx93 equivalent of commit 94e6197dadc9 ("arm64: dts:
imx8mp: Add LCDIF2 & LDB nodes")
Patch 5 adds LVDS DT overlay for tqma9352-mba93xxla platform
Patch 6 adds LVDS DT overlay for tqma9352-mba93xxca platform

Changes in v3:
* Collected Peng's R-b
* Fixed subject prefix in patch 3/6
* Fix 'ranges' property both in bindings example and .dtsi

Changes in v2:
* Rebased to next-20250221
* Reordered patches
* Added 'ranges' to bindings
* Use subnode constraint styles as suggested by Rob Herring
* Use IMX93_CLK_SYS_PLL_PFD0 as parent for IMX93_CLK_MEDIA_AXI
* Use 333MHz for IMX93_CLK_MEDIA_AXI
* Do not set board compatible in orverlays
* Add MBa93xxCA platform as well

I skipped the support for dynamic PLL configuration for now. This is a
separate task, see [2].

Best regards,
Alexander
