DSISRC __________ __\_ | \ pll4_p_ck ->| 1 |____dsi_k ck_dsi_phy ->| 0 | |____/ A DSI clock is missing in the clock framework. Looking at the clk_summary, it appears that 'ck_dsi_phy' is not implemented. Since the DSI kernel clock is based on the internal DSI pll. The common clock driver can not directly expose this 'ck_dsi_phy' clock because it does not contain any common registers with the DSI. Thus it needs to be done directly within the DSI phy driver.
