Subject: [PATCH 4.4 09/40] ARM: davinci: da8xx: specify dma_coherent_mask for lcdc
Date: Thu, 18 Jul 2019 12:02:05 +0900 [thread overview]
Message-ID: <20190718030041.407049117@linuxfoundation.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
