ARM: dts: Fix WLAN interrupt line for AM335x EVM-SK
While Sitara AM335x SoCs are very close to OMAP SoCs, the 32-line GPIO controllers are numbered from 0 on AM335x and from 1 on OMAP. But when the configuration for the TI WLAN controllers was converted from platform data to device tree, this detail was overlooked, as 10 boards were using OMAP with the WL12xx and WL18xx controllers, and only one was based on AM335x. This invalid configuration prevents the WL1271 module on the AM335x EVM-SK from notifying interrupts to the SoC, and breaks the wlan driver. The DTS must be corrected to use the correct GPIO controller. Signed-off-by: Romain Izard <romain.izard.pro@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
