Subject: [PATCH] ath79: add support for reset key on MikroTik RB912UAG-2HPnD
|
|
|
|
On MikroTik RB91x board series a reset key shares SoC gpio
|
|
line #15 with NAND ALE and NAND IO7. So we need a custom
|
|
gpio driver to manage this non-trivial connection schema.
|
|
Also rb91x-nand needs to have an ability to disable a polling
|
|
of the key while it works with NAND.
|
|
|
|
While we've been integrating rb91x-key into a firmware, we've
|
|
figured out that:
|
|
* In the gpio-latch driver we need to add a "cansleep" suffix to
|
|
several gpiolib calls,
|
|
* When gpio-latch and rb91x-nand fail to get a gpio and an error
|
|
is -EPROBE_DEFER, they shouldn't report about this, since this
|
|
actually is not an error and occurs when the gpio-latch probe
|
|
function is called before the rb91x-key probe.
|
|
We fix these related things here too.
