Subject: [PATCH 04/14] pwm: meson: change MISC_CLK_SEL_WIDTH to MISC_CLK_SEL_MASK
Date: Sat, 25 May 2019 20:11:23 +0200	[thread overview]
Message-ID: <20190525181133.4875-5-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190525181133.4875-1-martin.blumenstingl@googlemail.com>

MISC_CLK_SEL_WIDTH is only used in one place where it's converted into
a bit-mask. Rename and change the macro to be a bit-mask so that
conversion is not needed anymore. No functional changes intended.
