This patch enables both RXC and TXC 2ns dll delay lines on the
KSZ9131 PHY. Both are neede because the i.MX8MM SoC is RGMII v1.3
compliant. This means we need the TXC delay of the PHY.

Add CTRL_SLEEP_MOCI required for e.g. the Dahlia carrier board.

The hardware of verdin has some bypass caps after the switch that
switches power to the sd-card. These caps are resulting in a slow
discharge.
Add off-on-delay to set a minimum off-time of the regulator so it
can fully discharge until it turns on again.

Add a 'sleep' pinmuxing which prevents driving RGMII pins and backfeed the
unpowered Ethernet PHY.
When switching the Ethernet PHY supply off, it takes about 400 ms for
the PHY power to go down. So wait a minimum of 500 ms before reenabling
the PHY supply.

After the Ethernet PHY supply is enabled an RC holds the reset asserted
for about 120 ms. Reduce the time waited from 1000 ms to 200 ms which
should account for any possible tolerance.
U-Boot enables the PHY supply, switching it off in Linux with the RGMII
pins allready muxed creates backfeeding, thus set regulator-boot-on.

Use a OV5640 camera driver which works with the i.MX8 MM camera stack.

This patch adds the device tree to support Toradex Verdin iMX8M Mini a
computer on module which can be used on different carrier boards.
The module consists of an NXP i.MX 8M Mini family SoC, a Rohm BD71847
PMIC, a Gigabit Ethernet PHY, 2 GB of LPDDR4 RAM, an eMMC, an ADC, a
Secure Element, an EEPROM, an RTC, USB host and OTG ports, PCIe and
MIPI-CSI2/DSI interfaces plus optional Bluetooth/Wi-Fi module and CAN
controllers.
Anything that is not self-contained on the module is disabled by
default.
The device tree for the Verdin Development Board includes the module's
device tree and enables the supported peripherals of the carrier board
(the Verdin Development Board supports almost all of them).
Not yet tested:
- all UARTs other than console/debug Verdin UART_3
- push button controller on carrier board
- JTAG
- I2S to Wi-Fi
- I2S to DSI Mezzanine
Not yet working:
- carrier board audio
- MIPI-CSI2
- carrier board power gating
- FTDI control signals and JTAG
