[PATCH v1 0/7] Add verdin imx8m[mp] and imx95 zinnia board

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add Zinnia Carrier Board mated with Verdin iMX8M Plus, Verdin iMX8M Mini and
Verdin iMX95.

It features 1 x RS232, 1 x RS485, 1 x CAN, 3 x isolated digital I/O,
2 x 1GBit/s Ethernet, a mini PCIe slot with USB / SIM card connector
for a modem, USB and SD card interfaces.

Some small fixes and cleanup are done on the SOM dtsi file, in preparation
for the Zinnia addition.

Shawn, Frank: bindings/arm/fsl.yaml still list Shawn as maintainer, maybe
confirm that this is wanted.

[PATCH v1 2/7] arm64: dts: freescale: imx8mm-verdin: Split UART_2 pinctrl group

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Some carrier board reuse the UART_2 control signals as GPIO, split
the pinctrl RTS/CTS in separated nodes to maximize flexibility.

[PATCH v1 4/7] arm64: dts: freescale: imx8mp-verdin: Split UART_2 pinctrl group

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Some carrier board reuse the UART_2 control signals as GPIO, split
the pinctrl RTS/CTS in separated nodes to maximize flexibility.

[PATCH v1 5/7] arm64: dts: freescale: imx8mp-verdin: Add Zinnia

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add Zinnia Carrier Board mated with Verdin iMX8M Plus.

It features 1 x RS232, 1 x RS485, 1 x CAN, 3 x isolated digital I/O,
2 x GBit/s Ethernet, a mini PCIe slot with USB / SIM card connector
for a modem, USB and SD card interfaces.

[PATCH v1 6/7] arm64: dts: freescale: imx95-verdin: Split UART_2 pinctrl group

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Some carrier board reuse the UART_2 control signals as GPIO, split
the pinctrl RTS/CTS in separated nodes to maximize flexibility.

[PATCH v1 7/7] arm64: dts: freescale: imx95-verdin: Add Zinnia

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add Zinnia Carrier Board mated with Verdin iMX95.

It features 1 x RS232, 1 x RS485, 1 x CAN, 3 x isolated digital I/O,
2 x GBit/s Ethernet, a mini PCIe slot with USB / SIM card connector
for a modem, USB and SD card interfaces.
