Subject: [PATCH 07/10] backlight: qcom-wled: Provide enabled_strings default for wled 4 and 5
Date:   Mon,  4 Oct 2021 21:27:38 +0200
Message-Id: <20211004192741.621870-8-marijn.suijten@somainline.org>
In-Reply-To: <20211004192741.621870-1-marijn.suijten@somainline.org>

Precedence: bulk

Only wled 3 sets a sensible default that allows operating this driver
with just qcom,num-strings in the DT; wled 4 and 5 require
qcom,enabled-strings to be provided otherwise enabled_strings remains
zero-initialized, resuling in every string-specific register write
(currently only the setup and config functions, brightness follows in a
future patch) to only configure the zero'th string multiple times.
