Subject: [PATCH 0/5] Add pin package management on STM32P157

Hi,

The series adds support of chip packages for STM32MP157 SOC.
Available packages are:

STM32MP_PKG_AA: LFBGA448 (18*18), 176 IOs
STM32MP_PKG_AB: LFBGA354 (16*16), 98 IOs
STM32MP_PKG_AC: TFBGA361 (12*12), 148 IOs
STM32MP_PKG_AD: TFBGA257 (10*10), 98 IOs

As ball-out is different between each package, this series covers those
differences by creating dedicated pinctrl dtsi files. Each dtsi pinctrl
package file describes the package ball-out through gpio-ranges. A new
dt property is also added ("st,package") to provide to stm32 pinctrl driver
the package to use and so the available pins.

stm32mp157a-dk1 / dk2 boards embed a STM32MP_PKG_AC (TFBGA361 (12*12))
package.
stm32mp157c-ed1 / ev1 boards embed a STM32MP_PKG_AA (LFBGA448 (18*18))
package.

Regards

Alex
