Subject: [RFC][BUG] arm/dts: OMAP3: set #interrupt-cells to two
Date: Sat, 30 Mar 2013 09:21:28 +0100 [thread overview]
Message-ID: <1364631689.3767.7.camel@mars> (raw)
This patch sets gpio #interrupt-cells from a falsely acquired '1' to '2'
referring to Documentation/devicetree/bindings/gpio/gpio-omap.txt:
The first cell is the GPIO number.
The second cell is used to specify flags:
bits[3:0] trigger type and level flags:
1 = low-to-high edge triggered.
2 = high-to-low edge triggered.
4 = active high level-sensitive.
8 = active low level-sensitive.
But using this trigger cell in a board specific devicetree leads to a
non-starting kernel. This is due to not yet enabled gpio-clocks while
kernel/irq/irqdomain.c tries to set this trigger-flag (from the second
interrupt-cell) to gpio-irq-controller.
Any ideas?
