[PATCH 0/2] drm/msm: Fixes for issues seen on DB410c

[Archit Taneja <architt@codeaurora.org>]

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.

Archit Taneja (2):
  drm/msm/dsi: Queue HPD helper work in attach/detach callbacks
  drm/msm: Don't provide 'is_enabled' PLL clk_ops
