Subject: [PATCH 2/6] dt-bindings: clock: add DDR3 standard speed bins.
Date: Thu, 19 Apr 2018 12:40:15 +0200	[thread overview]
Message-ID: <20180419104019.24406-3-enric.balletbo@collabora.com> (raw)
In-Reply-To: <20180419104019.24406-1-enric.balletbo@collabora.com>

DDR3 SDRAM Standard (JESD79-3F) defines some standard speed bins for
DDR3 memories. The devfreq/rk3399_dmc.txt binding refers to this file
which does not exist, so add a ddr.h file with the standard speed bins
for DDR3.

Fixes: c1ceb8f7c167 (Documentation: bindings: add dt documentation for rk3399 dmc)
Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com>
