Subject: [PATCH] pinctrl-sunxi: Fix sun5i-a13 port F multiplexing
|
||
|
|
|
||
|
|
The correct value for selecting the mmc0 function on port F pins is 2 not 4,
|
||
|
|
as per the data-sheet:

Subject: [PATCH] pinctrl-sunxi: Fix hang on gpio irq
|
||
|
|
|
||
|
|
Our irq handler was missing chained_irq_enter / exit calls, causing a
|
||
|
|
hard hang as soon as a gpio irq happened.
