[PATCH v2 0/4] ast cleanups

[PATCH v2 0/4] ast cleanups

[Thomas Zimmermann]

Ast still has to be converted to managed initialization, and embed the
DRM device in the ast structure. In preparation of these changes, add
some cleanups to the driver.

Tested on ast HW.

v2:
	* remove device tests from ast_pm_freeze() (Daniel)
	* convert WARN_*() (Sam)
	* typo fixes

Thomas Zimmermann (4):
  drm/ast: Remove unused code paths for AST 1180
  drm/ast: Remove test for device from ast_pm_freeze()
  drm/ast: Upcast from DRM device to ast structure via to_ast_private()
  drm/ast: Use per-device logging macros

[PATCH v2 1/4] drm/ast: Remove unused code paths for AST 1180

[Thomas Zimmermann]

The ast driver contains code paths for AST 1180 chips. The chip is not
supported and the rsp code has never been tested. Simplify the driver by
removing the AST 1180 code.

[PATCH v2 2/4] drm/ast: Remove test for device from ast_pm_freeze()

[Thomas Zimmermann]

The driver cannot suspend before it has loaded completely. So the test
for device pointers is not required. Remove them.

[PATCH v2 3/4] drm/ast: Upcast from DRM device to ast structure via to_ast_private()

[Thomas Zimmermann]

All upcasting from struct drm_device to struct ast_private is now
performed via to_ast_private(). Using struct drm_device.dev_private
is deprecated. The ast variable in ast_crtc_helper_atomic_check() is
unused, so removed it.

v2:
	* fix typo in commit message

[PATCH v2 4/4] drm/ast: Use per-device logging macros

[Thomas Zimmermann]

Converts the ast driver to drm_info(), drm_err() and drm_WARN_*(). No
functional changes are made.

v2:
	* also convert WARN_*() macros
