[PATCH 5/6] mfd: ti_am335x_tscadc: fix reading a tsc property from DT

From: Dario Binacchi
Date: Sun Oct 24 2021 - 11:09:33 EST


There was a spelling mistake on TSC/ADC binding where "coordinate" was
spelled as "coordiante".

As done by commit c9aeb249bf72 ("Input: ti_am335x_tsc - fix spelling
mistake in TSC/ADC DT binding"), "the approach taken was to first use
correct spelling and if that fails, fall back to miss-spelled version".
