+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.
