From 720927249788826e0e72c3c6ee3b696a0188ed4d Mon Sep 17 00:00:00 2001 From: John Keeping Date: Wed, 7 Sep 2022 12:06:32 +0100 Subject: [PATCH] video: dw_mipi_dsi: fix [hv]sync active vs back porch The wrong fields are pulled out of the timings here so the values programmed into the DSI_VID_HSA_LINES/DSI_VID_HBP_LINES and DSI_VID_VSA_LINES/DSI_VID_VBP_LINES registers are swapped. Use the right fields so that the correct values are programmed.
