From: Peng Fan Date: Thu, 27 Mar 2025 00:49:45 +0000 (+0800) Subject: regulator: s5m8767: Convert to GPIO descriptors X-Git-Tag: v6.16-rc1~167^2~17^2 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ce2eadc6f99263dd200e52f692dc7a22698c99f3;p=thirdparty%2Fkernel%2Flinux.git regulator: s5m8767: Convert to GPIO descriptors Update the driver to fetch buck_gpio and buck_ds as GPIO descriptors. Then drop the usage of 'of_gpio.h' which should be deprecated. Based on commit 84618d5e31cf ("regulator: max8997: Convert to GPIO descriptors") as a reference to make the changes. With the quirk fix for s5m8767 in of_gpio_try_fixup_polarity, the polarity will be active-high, even if exynos5250 spring DTS wrongly use active-low polarity. So using GPIO descriptors, it should work as before.
