[why] When combining two or more pipes in DSC mode, there will always be more than 1 slice per line. In this case, as per DSC rules, the sink device is expecting that the ICH is reset at the end of each slice line (i.e. ICH_RESET_AT_END_OF_LINE must be configured based on the number of slices at the output of ODM). It is recommended that software set ICH_RESET_AT_END_OF_LINE = 0xF for each DSC in the ODM combine. However the current code only set ICH_RESET_AT_END_OF_LINE = 0xF when number of slice per DSC engine is greater than 1 instead of number of slice per output after ODM combine. [how] Add is_odm in dsc config. Set ICH_RESET_AT_END_OF_LINE = 0xF if either is_odm or number of slice per DSC engine is greater than 1.
