Cover letter [PATCH 0/3] pinctrl: meson: add support for the Meson8m2 SoC
Quoted 11 lines · Martin Blumenstingl
The Meson8m2 SoC is a variant of Meson8 with some updates from Meson8b (such as the Gigabit capable DesignWare MAC).
It is mostly pin compatible with Meson8, only 10 (existing) CBUS pins get an additional function. Four of these are Ethernet RXD2, RXD3, TXD2 and TXD3 (GPIOZ_0..GPIOZ_3) which are required when the board uses an RGMII PHY.GPIODV_24andGPIODV_25provide "VGA" support on Meson8, which doesn't seem to be supported on Meson8m2 anymore.
The other 4 areGPIOH_9(reg 3 bit 19),CARD_4(reg 8 bit 8),CARD_5(reg 8 bit 7) andGPIOY_3(reg 3 bit 11). Their function is currently unknown.

The AOBUS pins seem to be identical on Meson8 and Meson8m2. However, since there's no official documentation I decided to add a new compatible string.
