Subject: [PATCH 5.9 130/255] gpio: aspeed: fix ast2600 bank properties

From: Billy Tsai <billy_tsai@...eedtech.com>

[ Upstream commit 560b6ac37a87fcb78d580437e3e0bc2b6b5b0295 ]

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.
