Subject: ath79: resolve GPIO address conflicts
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=04942780734da56626d088d824a6117a74757637;p=openwrt%2Fstaging%2Flynxis.git

ath79: resolve GPIO address conflicts

The ar71xx GPIO driver only uses 0x24 registers, all following GPIO
registers are using to control pinmux functions, which are not handles
by the GPIO driver but the generic Linux pinctrl driver.

For some SoC conflicting address ranges were defined for these (AR7240 &
AR9330).

Resolve these cases and align the address space of the GPIO controller
between all SoCs, as the used address space of the driver is identical
for all these.
