Subject: [PATCH 4/8] arm64: dts: imx8mn: Correct interrupt flags in examples
Date: Tue,  8 Sep 2020 17:02:37 +0200	[thread overview]
Message-ID: <20200908150241.5771-4-krzk@kernel.org> (raw)
In-Reply-To: <20200908150241.5771-1-krzk@kernel.org>

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW  = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags, assuming the author of the code wanted some
logical behavior behind the name "ACTIVE_xxx", this is:
  ACTIVE_LOW  => IRQ_TYPE_LEVEL_LOW
