drm/ast: Fix incorrect register check for DRAM width

2016-03-24T10:01:02+00:00

commit 2d02b8bdba322b527c5f5168ce1ca10c2d982a78 upstream.

During DRAM initialization on certain ASpeed devices, an incorrect
bit (bit 10) was checked in the "SDRAM Bus Width Status" register
to determine DRAM width.

Query bit 6 instead in accordance with the Aspeed AST2050 datasheet v1.05.

drm/ast: Initialized data needed to map fbdev memory

2015-12-13T17:49:22+00:00

commit 28fb4cb7fa6f63dc2fbdb5f2564dcbead8e3eee0 upstream.

Due to a missing initialization there was no way to map fbdev memory.
Thus for example using the Xserver with the fbdev driver failed.
This fix adds initialization for fix.smem_start and fix.smem_len
in the fb_info structure, which fixes this problem.

drm/ast: Fix HW cursor image

2014-11-17T14:11:47+00:00

commit 1e99cfa8de0f0879091e33cd65fd60418d006ad9 upstream.

The translation from the X driver to the KMS one typo'ed a couple
of array indices, causing the HW cursor to look weird (blocky with
leaking edge colors). This fixes it.

drm/ast: Fix double lock at PM resume

2014-06-02T07:57:29+00:00

The recent commit [3ea87855: drm/helper: lock all around force mode
restore] introduced drm_modeset_lock_all() in
drm_helper_resume_force_mode() itself, while ast driver still takes
this lock before calling it.  Remove the caller side lock for avoid a
fatal deadlock.

Merge branch 'ast-updates' of ssh://people.freedesktop.org/~/linux into drm-next

2014-05-19T01:15:08+00:00

Pull in latest updates to AST driver.

* 'ast-updates' of ssh://people.freedesktop.org/~/linux:
  drm/ast: initial DP501 support (v0.2)
  drm/ast: rename the mindwm/moutdwm and deinline them
  drm/ast: resync the dram post code with upstream
  drm/ast: add AST 2400 support.
  drm/ast: add widescreen + rb modes from X.org driver (v2)

drm/ast: initial DP501 support (v0.2)

2014-05-19T01:13:57+00:00

This is the initial attempt at porting the DP501 code from the userspace
driver,

the firmware file is in
http://people.freedesktop.org/~airlied/ast_dp501_fw.bin

this should really be exposed as another encoder/connector that is cloneable

v0.2:
init 3rd tx properly,
add scratch reduction of VRAM size
backup firmware properly.
