Subject: [PATCH v1 1/2] pinctrl: bcm: bcm2835: Switch to use ->add_pin_ranges()
Date: Thu, 12 Jan 2023 18:38:24 +0200	[thread overview]
Message-ID: <20230112163825.72983-1-andriy.shevchenko@linux.intel.com> (raw)

Yeah, while the ->add_pin_ranges() shouldn't be used by DT drivers,
this one requires it to support quite old firmware descriptions that
do not have gpio-ranges property.

The change allows to clean up GPIO library from OF specifics.
There is no functional change intended.
