This adds support for the Kontron i.MX8MP OSM-S size system-on-module +
eval board.
CPU: NXP i.MX8MP @ 1600MHz (quad-core A53)
Memory: 4 (up to 8) GByte LPDDR4-RAM
Storage: 32 (up to 128) GByte eMMC + microSD slot
Ethernet: 2x 1 Gbit/s IEEE (1x with TSN)
UART: 1x UART console output on the Mini-B USB Debug Port
(signals are really UART on this Mini-B USB port!!!, there is
an adapter with ftdi available from Kontron)
1x RS232, 1x RS485
USB: 2x USB 2.0 Type-A, 1x USB 3.0 Type-C DRP
Misc: 8 (up to 128) kByte EEPROM (at24), RTC, 2x CAN, HDMI, 1x PCIe
This will create an SD card image for the board.
To use this image you have to bring the board to the recovery boot mode
(normal boot mode is eMMC). At the time of writing, the SoM (or the SoC)
has a bug that the FORCE_RECOVERY signal (switch S1 on the eval board)
doesn't work as long as the eMMC boot0 partition contains data.
Therefore you have to wipe this boot0 partition to be able to boot from
SD card. To do this call the following commands at uboot:
mmc dev 0 1
mmc erase 0 0x2000
After that, the system will try to boot from SD card.

Subject: arm64: dts: imx8mp-kontron-dl: change touchscreen power-supply to
|
|
AVDD28-supply
|
|
|
|
Update the touchscreen power-supply from 'power-supply' to 'AVDD28-supply' and
|
|
'VDDIO-supply' as per the binding documentation in goodix.yaml.
|
|
|
|
Fix below warning:
|
|
arch/arm64/boot/dts/freescale/imx8mp-kontron-dl.dtb: touchscreen@5d:
|
|
'power-supply' does not match any of the regexes: 'pinctrl-[0-9]+'
|
|
