Subject: ARM: dts: exynos: Fix invalid GIC interrupt flags in exynos4210
X-Git-Tag: v4.10-rc1~82^2~22^2~12
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=71990ea32f1fd4b7242380e46f0febd5c1b9c61c;p=karo-tx-linux.git

ARM: dts: exynos: Fix invalid GIC interrupt flags in exynos4210

Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and
generates an error:
	genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68)

The GIC requires shared interrupts to be edge rising or level high.
Platform declares support for both.  Arbitrarily choose level high
everywhere hoping it will work on each platform.
