Subject: [PATCH v3 0/3] drm/rockchip: lvds: probe logging improvements

Getting the panel already uses dev_err_probe to stay silent, when
the panel just probes later, and the lvds defers.

But the phy needed on px30, also has the capability to probe after
the lvds. So make the rest of the lvds probe/bind logic also use
more modern logging than DRM_DEV_ERR, that is deprecated anyway.

changes in v3:
- add patch to lower warning level on missing pinctrl (Quentin)
- one more dev_err_probe (Quentin)

changes in v2:
- reword the messages about getting (and preparing) pclk (Quentin)
- use a ret = dev_err_probe(dev, -EINVAL, ...) pattern
  in some (additional) places (Quentin)

Heiko Stuebner (3):
  drm/rockchip: lvds: move pclk preparation in with clk_get
  drm/rockchip: lvds: Hide scary error messages on probe deferral
  drm/rockchip: lvds: lower log severity for missing pinctrl settings
