From 79a86adf2279336617ad7d4f0813f040b17318d4 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 23 Feb 2016 10:14:34 +0800 Subject: MLK-12425-2: video: epdc: introduce epdc support Support EPDC. E-Ink feature is supported by i.MX6DL/SL and i.MX7D. For now this driver only supports i.MX6DL/SL, because the i.MX7D EPDC driver needs pxp support which is not included in U-Boot. Support user defined logo file, if there is no logo file, it will draw a black border around a white screen. If need to enable EPDC, a waveform file is required to let all work. Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME support. Please refer to Linux Reference Manual for how to flash WAVEFORM file.
