0fa60e3c2a ARM: imx: Let SPL configure ECSPI1 clock on Data Modul i.MX8M Plus eDM SBC
The SPL clock code does configure the ECSPI clock frequency, which has
to match the mxc-spi driver configuration for successful SPI NOR boot.
Drop the assigned-clock from DT ecspi1 node on this board to let the
SPL clock code do the configuration and keep it aligned with the driver
expectation.

32a41b7c37 ARM: imx: Auto-detect PHY on Data Modul i.MX8M Mini/Plus eDM SBC
Implement fdtdec_board_setup() auto-detection of ethernet PHY.
This uses properties of the hardware and pull resistor placement.

If GPIO1_16 RGMII_MDC is HIGH, then R530 (MX8MM eDM SBC) or
R390 (MX8MP eDM SBC) is populated. R530 or R390 is populated
only on boards with AR8031 PHY.

If GPIO1_16 RGMII_MDC is LOW, then the in-SoM pull down is the
dominant pull resistor. This is the case on boards with BCM54213PE
PHY.

In case AR8031 PHY is populated, the PHY MDIO address is 0, in
case BCM54213PE PHY is populated, the PHY MDIO address is 1, the
fdtdec_board_setup() is used to patch the correct address into
the U-Boot control DT.

Enable broadcom PHY support to support both PHYs.

1f25c75619 ARM: dts: imx: Power off display output on Data Modul i.MX8M Mini/Plus eDM SBC
Turn display connector power off on boot and reboot to prevent any
bogus start up sequence of any panel potentially attached to the
display connector.

6bd39dee63 ARM: dts: imx: Switch USB1 port control to GPIO on Data Modul i.MX8M Plus eDM SBC
The USB_PWR signal operation is not reliable on this DWC3 controller
instance in case the signal is active high. Switch to GPIO control,
which always behaves correctly. Perform the change in u-boot extras
until this hits Linux upstream.
