[PATCH v3 3/3] arm64: dts: freescale: Add phyBOARD-Polis-i.MX8MM support
Teresa Remmet
t.remmet at phytec.de
Tue Jun 21 00:10:48 PDT 2022
Add initial support for phyBOARD-Polis-i.MX8MM.
Main features are:
* Bluetooth and Wifi
* CANFD
* eMMC
* i2c RTC
* Ethernet
* PCIe
* RS232/RS485
* SD-Card
* SPI-NOR flash
* USB

Changes in v3:
- move "enable-active-high" after "gpio" property
- Add missing newlines before child nodes
- sort i2c devices by address
Changes in v2:
- added missing space in compatible of imx8mm-phyboard-polis-rdk
- removed underscores in node names
- fixed indentation of reg_usdhc2_vmmc node
- put status always as last property of nodes
- updated node name of sn65dsi83 to bridge
