Subject: [PATCH v2 02/16] mmc: meson-gx: remove CLK_DIVIDER_ALLOW_ZERO clock flag
Date: Mon, 21 Aug 2017 18:02:47 +0200 [thread overview]
Message-ID: <20170821160301.21899-3-jbrunet@baylibre.com> (raw)
In-Reply-To: <20170821160301.21899-1-jbrunet@baylibre.com>
Remove CLK_DIVIDER_ALLOW_ZERO. This flag means that a 1 based divider
with a 0 value will behave as a bypass clock
The mmc divider does not behave like this, a 0 value disables the clock
Remove this flag so CCF never allows a 0 value on this clock
Fixes: 51c5d8447bd7 ("MMC: meson: initial support for GX platforms")
