Subject: [PATCH v2] ARC: [plat-hsdk]: Add support of Vivante GPU
Date: Fri, 1 Feb 2019 15:12:11 +0300 [thread overview]
Message-ID: <20190201121211.23701-1-Eugeniy.Paltsev@synopsys.com> (raw)
HSDK board has built-in Vivante GPU IP which works perfectly fine
with Etnaviv driver, so let's use it.
Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

Changes v1->v2:
* Add clock inputs to etnaviv device tree node (reported by Lucas Stach)
