The ADV7533 driver and DT bindings for MDSS hardware are both available in 4.9, which is sufficient to boot with HDMI display on DB410c. With the drm/msm and ADV7533 enabled, the system hangs during boot. One reason is that the PLL driver tries to access registers without the necessary interface clocks enabled. The other reason is a deadlock caused by calling drm_hpd_helper_irq_event in a context that might already hold drm_device's mode_config.mutex.
