X-Git-Tag: v6.14-rc1~103^2^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2f5b33ff11310df1e6e17716650a283270c72fad;p=thirdparty%2Fkernel%2Flinux.git

ARM: dts: aspeed: minerva: add i/o expanders on bus 0

Add three I/O expanders on i2c bus 0, assign the GPIO line name to each
GPIO in use, and specify the interrupt GPIO that has been used on it and
give the interrupt gpio number.
