X-Git-Tag: v6.19-rc1~146^2~61
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9631a10083d843b57b371d406235e2f2a3e49285;p=thirdparty%2Flinux.git

gpio: tegra186: Add support for Tegra410

Extend the existing Tegra186 GPIO controller driver with support for
the GPIO controller found on Tegra410. Tegra410 supports two GPIO
controllers referred to as 'COMPUTE' and 'SYSTEM'.
