Subject: [PATCH 00/22] Add support for A100/A133 display

This series depends on [1] for the eMMC/MMC controller to work and
[2] (lined up for 6.14) which adds support for the sram nodes and
display engine extends it's usage. Idea of this series to get initial
feedback and adjust, which will be rebased for 6.14 once [2] is merged.

This patch series adds support for A133 display pipeline based on
LVDS. dt-bindigs are organized in the start and later with code
changes.

PHY is shared between DSI and LVDS, so to control the PHY specific
to DSI/LVDS, phy_ops set_mode is introduced. To enable the DSI
using set_mode, analog control register MIPI Enable is used, which
may not be available for A31 (shares the same driver).

Otherwise, A133 also got hidden independent display engine i.e
mixer + tcon top to handle parallel display. But this patch series
adds only support for the 1 mixer which is documented.
