[PATCH v4 00/12] Add support for pinmux status command on beaglebone

[Dario Binacchi]

The series was born from the need to check the pinmux setting of a
peripheral on a beaglebone board. I then ran the 'pinmux status -a'
command but it failed because some operations (get_pin_muxing,
get_pin_name and get_pins_count) were missing in the 'pinctrl-single'
driver.

The patch series can be cleanly applied to the HEAD of the master which
at the time of release points to 3f2e3c7845
("Merge tag 'u-boot-stm32-20210409' of https://source.denx.de/u-boot/custodians/u-boot-stm")
