From: Linus Walleij Date: Sun, 2 Dec 2018 08:43:23 +0000 (+0100) Subject: ARM: pxa: Add GPIO descriptors for Palm27x X-Git-Tag: v5.4-rc1~1936^2~48 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=58e2d877e37018b3804ab2601d9c9ad3fbcc74e7;p=platform%2Fkernel%2Flinux-rpi.git ARM: pxa: Add GPIO descriptors for Palm27x The Palm27x devices set up the MMC card detect and write protect lines with a special helper function. Augment this helper function to also accept an optional GPIO descriptor table and pass and register this for all the Palm27x devices in that family.
