Seems applying this dts change before the clock patch is applied would break wlan so please let me know when this is safe to apply. Regards, Tony

WLAN did only work if clock was left enabled by the original system, so make it fully enable the needed resources itself. Signed-off-by: Andreas Kemnade <andreas@kemnade.info> --- arch/arm/boot/dts/ti/omap/omap4-epson-embt2ws.dts | 8 ++++++++ 1 file changed, 8 insertions(+)
