[PATCH v2 0/2] arm64: dts: st: Couple of updates for STM32MP23

[Amelie Delaunay]

Remove gpioj and gpiok nodes, as J and K banks are unavailable
on STM32MP23x packages and resize memory on stm32mp235f-dk
because DDR controller control pin is not routed, so it is not
possible to configure 4GB/16-bit.

[PATCH v2 1/2] arm64: dts: st: remove gpioj and gpiok banks from stm32mp231

[Amelie Delaunay]

STM32MP23x supports AJ, AK and AL packages, where PI12 to PI15, PJ0 to
PJ15 (whole J bank) and PK0 to PK7 (whole K bank) pins are not available.

It means gpioj and gpiok nodes are useless in stm32mp231. Remove them.

[PATCH v2 2/2] arm64: dts: st: fix memory region size on stm32mp235f-dk

[Amelie Delaunay]

STM32MP23x SoCs provide a DDR controller supporting up to 4GB/16-bit.
The control pin to properly configure 4GB/16-bit is not routed on
stm32mp235f-dk, that's why the board only supports 2GB.
