Subject: [PATCH] pinctrl: sunxi: create irq/pin mapping during init
|
||
|
|
|
||
|
|
The irq/pin mapping is used to lookup the pin to mux to the irq
|
||
|
|
function when the irq is enabled. It is created when gpio_to_irq
|
||
|
|
is called. Creating the mapping during init allows us to map the
|
||
|
|
interrupts directly from the device tree.
