From: Michal Piekos Date: Sat, 16 May 2026 05:34:15 +0000 (+0200) Subject: iio: adc: sun20i-gpadc: add A523 gpadc support X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8114f4420360260576cbd6d0633b28a607321f0b;p=thirdparty%2Fkernel%2Flinux.git iio: adc: sun20i-gpadc: add A523 gpadc support A523 differs from existing sun20i-gpadc-iio by having two clocks; bus clock and module clock. Change driver to enable all clocks.
