Subject: [PATCH] gpio: aspeed: fix ast2600 bank properties
Git-commit: 560b6ac37a87fcb78d580437e3e0bc2b6b5b0295
Patch-mainline: v5.10-rc4
References: git-fixes

GPIO_T is mapped to the most significant byte of input/output mask, and
the byte in "output" mask should be 0 because GPIO_T is input only. All
the other bits need to be 1 because GPIO_Q/R/S support both input and
output modes.
