Subject: [PATCH v2 12/13] exynos/fimg2d: add g2d_reset() to public API
Date: Sun, 22 Nov 2015 19:48:42 +0100	[thread overview]
Message-ID: <1448218123-21292-13-git-send-email-tjakobi@math.uni-bielefeld.de> (raw)
In-Reply-To: <1448218123-21292-1-git-send-email-tjakobi@math.uni-bielefeld.de>

After the rewrite of the command buffer submission
handling g2d_reset() is no longer called internally.

Still the user might want to reset the G2D
context so expose this call.
