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.

This one is actually v3 :-) No worries :y Koen _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
