Hi, These set of patches are for enabling DSI command mode on CHT. Command Mode refers to an operation in which transactions primarily take the form of sending commands and data to a peripheral that incorporates a display controller. The display controller may include local registers and a frame buffer. The host processor indirectly controls activity at the peripheral by sending commands, parameters and data to the display controller. Sink refreshes from its local frame buffer. Image updates require Source to write new data into the frame buffer which Source sends in the form of command + payload. The command mode panel we have here is 1080 x 1920. For this panel, features like support of i2c transactions for sending backlight on sequence, VBT version 3 patches, GPIO configuration changes for CHT are required. The same has been floated as part of different patch series. Floating the command mode enabling patches separately to start with the review. These patches have been rebased on top of BXT MIPI, BXT dual link changes.
