[PATCH v3 6/7] clocksource: sh_cmt: Remove unused "renesas,channels-mask" handling
From: Geert Uytterhoeven
Date: Mon Sep 18 2017 - 09:47:30 EST
The in-driver channel configuration in sh_cmt_info.channels_mask is now
always set for all CMT devices instantiated from DT.
Hence the "renesas,channels-mask" property is no longer checked, and its
handling can be removed, cfr. commit 4e18111ff38f0664 ("devicetree:
bindings: Remove deprecated properties").
