Subject: gpio: of: Scan available child node for gpio-hog
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d1279d94b4e47c3684f936ed6b6c89d3dd2cd5b9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

gpio: of: Scan available child node for gpio-hog

Look for child node which are available when iterating for
gpio hog node for request/set GPIO initial configuration
during OF gpio chip registration.

All it really does is make it possible to set
status = "disabled"; in the hog nodes, and then they will
not be applied.
