X-Git-Tag: v6.6.17~7434^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d3bf3dc4bbbf6109bd9b4bd60089d36205ec4a37;p=platform%2Fkernel%2Flinux-rpi.git

gpio: realtek-otto: Add RTL931x support

The RTL931x SoC series has support for 32 GPIOs, although not all lines
may be broken out to a physical pad.

The GPIO bank's parent interrupt can be routed to either or both of the
SoC's CPU cores by the GIC. Line-by-line IRQ balancing is not possible
on these SoCs.
