[v2,0/4] drm/msm/mdss: enable access to hw_rev from MDSS driver

Message

On newer platforms mdss can read hw_rev register. On older platforms the
mdss driver can not read hw_rev register (to determine the platform).
Add optional 'core' clock that enables access to MDSS registers before
MDP5/DPU device is bound (and enabled the core clock).

Dmitry Baryshkov (4):
  dt-bindings: display/msm: add core clock to the mdss bindings
  drm/msm/mdss: enable optional core clock for MDP5 MDSS
  drm/msm/mdss: check for core clk before accessing HW_REV
  drm/msm/mdss: move is_mdp5 condition to msm_mdss_init
