Subject: [PATCH v2 04/14] pwm: meson: change MISC_CLK_SEL_WIDTH to MISC_CLK_SEL_MASK
Date: Sat, 8 Jun 2019 20:06:16 +0200 [thread overview]
Message-ID: <20190608180626.30589-5-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190608180626.30589-1-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.
