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

[Otavio Salvador]

From: Fabio Estevam <festevam@gmail.com>

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.

[PATCH 3/9] ARM: dts: imx7d-pico-pi: Move SoM related part to imx7d-pico.dtsi

[Otavio Salvador]

From: Fabio Estevam <festevam@gmail.com>

imx7d-pico-pi board contains:

- One SoM board (imx7d pico)
- One base board (pi).

In order to make it easier for adding support for other board variants,
move the commom SoM part to the imx7d-pico.dtsi file.

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

[Otavio Salvador]

handle name was too restrictive. This reworks it to a more generic and
meaningful name.

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

[Otavio Salvador]

From: Fabio Estevam <festevam@gmail.com>

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
