2019-03-04device/mmio.h: Add include file for MMIO opsKyösti Mälkki
MMIO operations are arch-agnostic so the include path should not be arch/.

This removes CEIL_DIV and div_round_up() altogether and replace it by DIV_ROUND_UP defined in commonlib/helpers.h.

2017-04-25mediatek/mt8173: Add support for Dual DSI outputJitao Shi
The MT817x display output pipeline can be configured to drive an 8-lane MIPI/DSI panel using "dual DSI" mode. For the "dual DSI" video data path, the UFO block is configured to reorder the data stream into left and right halves which are then sent by the SPLIT1 block to the DSI0 and DSI1 respectively. The DSI0 and DSI1 outputs are then synchronously clocked at half the nominal data rate by their respective MIPI_TX0/MIPI_TX1 phys. Also, update the call sites in oak mainboard to avoid build breakage.

2016-07-26meditek/mt8173: dsi: set mipi pin driving control onJitao Shi
We set this driving control to prevent signal attenuation caused by LVDS DRV termination. When DA_LVDSTX_PWR_ON is not set, LVSH has no power and LVDS DRV termination status is unknown (floating). This creates a chance that MIPI output would be influenced. The DSI's LP signal will be half voltage attenuation. There will be no display on panel. When DA_LVDSTX_PWR_ON is set, LVSH and LVDS DRV termination are effective and termination is fixed OFF. The DSI won't be influenced. We only need to set this register once, so we set it here to prevent repeatedly setting in the kernel when the system goes to recovery mode.
