"I2C Master Interface Extended Read Mode" implements a segment pointer-based read operation using the Special Register configuration. This patch fix https://patchwork.kernel.org/patch/7098101/ mentioned "The current implementation does not support "I2C Master Interface Extended Read Mode" to read data addressed by non-zero segment pointer, this means that if EDID has more than 1 extension blocks, EDID reading operation won't succeed" With this patch, dw-hdmi can read EDID data with 1/2/4 blocks.
