From: Martin Blumenstingl Date: Sun, 29 Oct 2017 23:17:15 +0000 (+0100) Subject: ARM: dts: meson: fix the memory region of the GPIO interrupt controller X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9fd7a2e063993a9d47f444147520b9e7fcea4c99;p=openwrt%2Fstaging%2Fblogic.git ARM: dts: meson: fix the memory region of the GPIO interrupt controller commit 200a575b68d2 ("ARM: dts: meson: organize devices in their corresponding busses") organized all peripherals in busses so that the base register offset of the bus doesn't have to be included in all child-nodes anymore. The GPIO interrupt controller however specifies the register offset without subtracting the "cbus" base address. This leads to a problem where of_iomap inside the irq-meson-gpio driver fails because it actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880 for the GPIO interrupt controller). Fix this by using 0x9880 as register offset.
