[PATCH v2 0/2] ARM64: meson-gxm: Add support for Khadas VIM2

[PATCH v2 0/2] ARM64: meson-gxm: Add support for Khadas VIM2

[Neil Armstrong]

The Khadas VIM2 is a Single Board Computer, respin of the origin
Khadas VIM board, using an Amlogic S912 SoC and more server oriented.
    
It provides the same external connectors and header pinout, plus a SPI
NOR Flash, a reprogrammable STM8S003 MCU, FPC Connector, Cooling FAN header
and Pogo Pads Arrays.

To eventually provide access to the SPI NOR flash, the eMMC DS pin must be
configured as a different pincrl node to disable it's access from the MMC
Controller. This first patch splits this emmc pins entry for GXBB and GXL.

Depends on eMMC ARM64 DT patches from Jerome Brunet at [2]

Changes since v1 at [1] :
 - Add acks from Martin and Rob
 - Cleanup external_phy node
 - Cleanup sd_emmc_a node
 - Rebased with eMMC ARM64 DT patches from Jerome Brunet at [2]

[PATCH v2 1/2] ARM64: dts: meson-gxl: Take eMMC data strobe out of eMMC pins

[Neil Armstrong]

Since the Data Strobe pin is optional, take it out of the default
eMMC pins and add a separate entry.
