[PATCH v3 1/4] pinctrl: qcom: move out of mach-snapdragon

Tue Nov 14 13:55:40 CET 2023
Move the Qualcomm pinctrl drivers out of mach-snapdragon and over to the
rest of the pinctrl drivers, adjust the drivers so that support for each
platform can be enabled/disabled individually and introduce platform
specific configuration options.
