Subject: [PATCH AUTOSEL 4.4 10/12] ARM: davinci: da8xx: specify dma_coherent_mask for lcdc
Date: Wed, 26 Jun 2019 20:42:32 -0400 [thread overview]
Message-ID: <20190627004236.21909-10-sashal@kernel.org> (raw)

[ Upstream commit 68f2515bb31a664ba3e2bc1eb78dd9f529b10067 ]
The lcdc device is missing the dma_coherent_mask definition causing the
following warning on da850-evm:
da8xx_lcdc da8xx_lcdc.0: found Sharp_LK043T1DG01 panel
