Description
On HTC platforms that use Qualcomm SoCs, mdss_dsi_parse_dcs_cmds is not used to parse the panels init sequence, which is defined with htc-fmt,mdss-dsi-on-command, htc-fmt,mdss-dsi-off-command and htc-fmt,display-on-cmds. Replacing htc-fmt with qcom does not work and causes the following error:
The above exception was the direct cause of the following exception:
