If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Fri Feb 23 11:48:40 CET 2018 From: Andre Przywara <andre.przywara@xxxxxxx> Date: Sat, 25 Nov 2017 12:12:30 +0000 Subject: pinctrl: sunxi: Fix A64 UART mux value From: Andre Przywara <andre.przywara@xxxxxxx> [ Upstream commit 7c5c2c2d18d778e51fd8b899965097168306031c ] To use pin PF4 as the RX signal of UART0, we have to write 0b011 into the respective pin controller register. Fix the wrong value we had in our table so far.
