Subject: ARM: dts: am4372: fix irq type for arm twd and global timer
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=84fb225ad257442d879a1f57c79184e31fb17aea;p=linux-beck.git

ARM: dts: am4372: fix irq type for arm twd and global timer

As per ARM documentation
PPI(0) ID27 - global timer interrupt is rising-edge sensitive.
PPI(2) ID29 - twd interrupt is rising-edge sensitive.

and the same is proved by GIC distributor register value
GIC_DIST_CONFIG(0xC04) = 0x7DC00000.

Hence, set IRQ triggering type to IRQ_TYPE_EDGE_RISING
for ARM TWD and Global timers.
