ARM: dts: imx: Add DT overlays for DH i.MX6 DHCOM SoM and boards
Add DT overlays to support DH i.MX6 DHCOM SoM carrier board expansion modules. The following DT overlays are implemented: - PDK2: - DH 497-200 Display board in edge connector X12 - DH 505-200 Display board in edge connector X12 - DH 531-100 SPI/I2C board in header X21 - DH 531-200 SPI/I2C board in header X22 - DH 560-200 Display board in edge connector X12 - PicoITX: - DH 626-100 Display board in edge connector X2 Signed-off-by: Marek Vasut <marex@nabladev.com> Signed-off-by: Frank Li <Frank.Li@nxp.com>
