[PATCH v3 0/2] arm64: dts: renesas: rzt2h-n2h-evk: Add LCDC overlays for RZ/T2H and RZ/N2H EVKs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Hi all,

This patch series adds Device Tree overlays for the LCDC on the RZ/T2H
and RZ/N2H EVKs. The overlays configure the necessary pin multiplexing
and settings for the LCDC to function correctly with the ADV7513 HDMI
transmitter.

Note:
- patch #2 is from series [0] as rest of the patches are already merged
  in renesas-tree sending this patch as a v3.
- patches apply on top of renesas-devel/renesas-dts-for-v7.4 branch

v2->v3:
- patch #1 is a new patch
- Renamed HEADER_IRQ8 to IRQ8
- Added irq support for the ADV7513 in the overlays
- Corrected the DIP switch settings for I2C_SDA1/I2C_SCL1
- Added missing DIP switch settings for LCDC_DATG3
- MOved the header include at the end
- Added a comment for i2c0 as to why it is disabled in the overlay
- Split up the du_pinctrl into a group of pins as only sync/de pins
  needed to set slew-rate=0, the rest of the pins can use slew-rate=1
- Updated commit message for patch #2 to reflect the changes in v3
