The PHY reset circuitry may keep the PHY in reset for up to 200ms after
powerup. Use the regulator startup-delay-us property to wait that time
before talking to the PHY.
While at it unify that regulator with the Linux dts file.

The FEC in the i.MX8MM doesn't have this feature. So don't pretend one
can use it.
Additionally in the 2018.03 downstream U-Boot the property is not
evaluated, not even for the i.MX8 and i.MX8X based machines.

Do not undef CMD config defines which are set by Kconfig. This
allows to enable those commands using Kconfig.

It turned out that on the new Apalis iMX8 QuadPlus V1.1A the
ethernet is no longer working. I suspect this due to missing
muxing for 1.8V/3.3V.
Due to that I copy the whole ethernet pinmux and node over from
the Linux side.

Sometimes an ethernet PHY interface can’t complete
auto-negotiation and returns “timeout” error.
Overriding default timeout value fixes this issue.

This commit adds initial support for the Toradex Verdin iMX8MM 2GB WB IT
V1.0A module. They are now strapped to boot from eFuses which are
factory fused to properly boot from their on-module eMMC. U-Boot
supports either booting from the on-module eMMC or may be used for
recovery purpose using the universal update utility (uuu) aka mfgtools
3.0.
Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Gigabit Ethernet
- GPIOs
- I2C
- USB_1 peripheral: fastboot or ums
- USB_2 host: USB mass storage
To prepare the program image for eMMC fastboot using imx-mkimage and
subsequently flash it using U-Boot proceed as follows:
cd imx-mkimage/
make SOC=iMX8MM flash_evk_emmc_fastboot
load mmc 1:1 $loadaddr flash.bin
setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
mmc dev 0 1
mmc write ${loadaddr} 0x2 ${blkcnt}
To prepare the program image for use with USB recovery aka serial
downloader using imx-mkimage and subsequently download using uuu
with an uuu.auto script proceed as follows:
cd imx-mkimage/
make SOC=iMX8MM flash_evk
uuu_version 1.3.34
SDP: boot -f flash.bin
CFG: SDPU: -vid 0x0525 -pid 0xb4a4
SDPU: delay 1000
SDPU: write -f flash.bin -offset 0x57c00
SDPU: jump
Fusing i.MX 8MM SoC and configuring eMMC for fastboot (already done
during manufacturing):
fuse prog 1 3 0x100020d6 (BT_FUSE_SEL, eMMC boot, SD1, fast boot, 4-bit DDR, high speed, 1.8V)
fuse prog 2 2 0x00000001 (enable boot ack)
mmc bootbus 0 1 0 2 (4-bit, reset bus width, DDR)
mmc partconf 0 1 1 0 (booting from boot area partition 1, send acknowledge)
SD manufaccture boot:
SD manufacture boot only works as long as the module is un-fused and
SD_1_PWR_EN is bypassed on the carrier board.
cd imx-mkimage/
make SOC=iMX8MM flash_evk
sudo dd if=iMX8M/flash.bin of=/dev/mmcblk0 bs=1024 seek=33

Just like on any and all other i.MX 8 Series devices use MMC1 for eMMC
and SD2 for SD card.
This fixes previously reverted commit 6c6206ad1a5a ("MLK-18243-17: arm:
mach-imx: fix sd to mmc1 and emmc to mmc2 for i.MX8MM").

i.MX8MM"
Nope, hard-coding SD to mmc1 and eMMC to mmc2 is wrong in so many ways!
This reverts commit 6c6206ad1a5a3c70118a3ecf526b0ff00088adf7.

When DM_REGULATOR is enabled, the driver attempts to call
regulator_autoset() which expects the regulators to be on at boot
and/or always on and fails if they are not true.
For a more generic approach, this patch just calls
regulator_set_enable() which shouldn't have such restrictions.
