pinctrl: stm32: rework SoC package and add STM32MP21

[PATCH v2 10/15] arm64: dts: st: introduce stm32mp21 pinctrl files
Posted by Antonio Borneo 1 week, 6 days ago
From: Amelie Delaunay <amelie.delaunay@foss.st.com>

Four packages exist for stm32mp21 dies. As ball-out is different between
them, this patch cover those differences by introducing dedicated pinctrl
dtsi files. Each dtsi pinctrl package file describes the package ball-out
through gpio-ranges.

Available packages are:
STM32MP21xxAL: 10*10 VFBGA361 / 123 GPIOs
STM32MP21xxAM: 14*14 VFBGA289 / 123 GPIOs
STM32MP21xxAN: 11*11 VFBGA273 / 123 GPIOs
STM32MP21xxAO: 8*8 VFBGA225 / 98 GPIOs

It includes also the common file used for pin groups definition.
