The spi0 controller on the A20 have up to 4 CS (Chip Select) while the
others three only have 1.
Add the num-cs property to each node.
The current driver doesn't read this property but this is useful for
downstream user of DTS (FreeBSD for example).

Use axp209.dtsi in sun7i-a20-olinuxino-lime2.dts and correct
some regulators.
DCDC2 is used for vdd-cpu so it should never be bellow 1V and above 1.4V
DCDC3 is used for VDD_INT so same as above.
LD01 is used for the RTC, and should have a typical value of 1.3V
LD02 is used for AVCC and should have a typical value of 3.0V
LD03/4 are used for Port-E/Port-G Power pin, and the schematics recommands
to set them to 2.8V as they can be used for CSI0/1.

The A31 Hummingbird has a mini USB OTG port, and uses GPIO pins from the
SoC for ID pin and VBUS detection and VBUS control. The PMIC can also do
VBUS detection and control.
Here we prefer to use the PMIC's DRIVEVBUS function to control VBUS for
USB OTG, as that is the hardware default.

In the past, all the MMC pins had
allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;
which was actually a no-op. We were relying on U-boot to set the bias
pull up for us. These properties were removed as part of the fix up to
actually support no bias on the pins. During the transition some boards
experienced regular MMC time-outs during normal operation, while others
completely failed to initialize the SD card.
Given that MMC starts in open-drain mode and the pull-ups are required,
it's best to enable it for all the pin settings.

The node name for the power seq pin is mmc2@0 like the mmc2_pins_a one.

While we now support the internal display pipeline found on sun6i, it
is possible that we are unable to enable the display for some boards,
due to a lack of drivers for the panels or bridges found on them. If
the display pipeline is enabled, the driver will try to enable, and
possibly screw up the simple framebuffer U-boot had configured.
Disable the display pipeline by default.

The sama5d36ek CMP board is the variant of sama5d3xek board.
It is equipped with the low-power DDR2 SDRAM, PMIC ACT8865 and
some power rail. Its main purpose is used to measure the power
consumption.
The difference of the sama5d36ek CMP dts from sama5d36ek dts is
listed as below.
1. The USB host nodes are removed, that is, the USB host is disabled.
2. The gpio_keys node is added to wake up from the sleep.
3. The LCD isn't supported due to the pins for LCD are conflicted
with gpio_keys.
4. The adc0 node support the pinctrl sleep state to fix the over
consumption on VDDANA.
As said in errata, "When the USB host ports are used in high speed
mode (EHCI), it is not possible to suspend the ports if no device is
attached on each port. This leads to increased power consumption even
if the system is in a low power mode." That is why the the USB host
is disabled.

The sama5d2 SoC has a second DMA controller and can be used just like DMA0.
By default both DMA controllers are configured as "Secure" in
MATRIX_SPSELR so we can use whichever we want in a "single Secure World"
configuration.
Surprisingly the DMA1 has a lower address than DMA0. To avoid confusion
place it after DMA0 node anyway.

Some peripherals are "Programmable Secure" but left as "Secure" by default.
If tried to be connected to Non-Secure DMA controller, the possibility to
leak secure data is prevented so using these peripherals with DMA1 is not
possible with this default configuration (MATRIX_SPSELR registers setup by
bootloader).
Move them to DMA0 which is an "Always-Secure" DMA controller.
