[PATCH 0/3] Add support for Renesas RZ/G3L LVDS encoder

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

Add support for the RZ/G3L LVDS encoder driver. It operates in single-link
mode with 4 lanes (Data) + 1 lane (Clock) and supports pixel clock rates
from 25 to 87 MHz. The LVDS module cannot be used at the same time as
MIPI-DSI. However, LVDS and the DSI interface share a peripheral clock and
the MIPI_DSI_PRESET_N reset signal. Also, the MIPI_DSI_CMN_RSTB and
MIPI_DSI_ARESET_N reset signals must be asserted before using the LVDS
module.
