From: Felipe Balbi Date: Mon, 11 Nov 2013 07:56:43 +0000 (-0800) Subject: Input: ti_am335x_tsc - fix spelling mistake in TSC/ADC DT binding X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c9aeb249bf72edcf1ca28fe301fb3cbb53cb23d8;p=linux-beck.git Input: ti_am335x_tsc - fix spelling mistake in TSC/ADC DT binding There was a spelling mistake on TSC/ADC binding where "coordinate" was spelled as "coordiante". We can't simply fix the error due to DT being an ABI, the approach taken was to first use correct spelling and if that fails, fall back to miss-spelled version. It's unfortunate that has creeped into the tree.
