Subject: [PATCH 1/9] ARM: dts: imx7d-pico: Do not harcode the memory size

From: Fabio Estevam <[email protected]>

Currently the memory size described in dts is 2GB, which is incorrect.

There are 512MB and 1GB versions of imx7d-pico boards, so remove
the hardcoded memory size and let the bootloader pass the correct
value to the kernel.

Subject: [PATCH 6/9] ARM: dts: imx7d-pico: Improve WiFi regulator name

There are different models of WiFi being used in the SoM and the
handle name was too restrictive. This reworks it to a more generic and
meaningful name.

Subject: [PATCH 7/9] ARM: dts: imx7d-pico: Extend peripherals support

From: Fabio Estevam <[email protected]>

This extends the peripherals supported by the imx7d-pico.dtsi. It
adds:

- I2C2
- Flexcan (flexcan1 and flexcan2 ports)
- USDHC1
- UART (6 and 7 ports)
- PWM (4 ports)
- eCSPI3
