Message-ID: <cover.1480064884.git.jsarha@ti.com> (raw)

The git branch bellow is updated.

Changes since v3:
- "drm/tilcdc: Enable sync lost error and recovery handling for rev 1 LCDC"
  - disable sync-lost irq also for rev1 LCDC
  - LCDC_V1_SYNC_LOST_ENA to LCDC_V1_SYNC_LOST_INT_ENA
- "drm/tilcdc: Enable palette loading for revision 2 LCDC too"
  - disable palette loaded interrupt after receiving it
- "drm/tilcdc: Enable frame done irq and functionality for LCDC rev 1"
  - disable FRAME_DONE interrupt for rev 1 lcdc in interrupt routine
  - LCDC_V1_FRAME_DONE_ENA to LCDC_V1_FRAME_DONE_INT_ENA
- Add: "drm/tilcdc: Configure video mode to HW in enable() not in mode_set_nofb()"
- Drop "drm/tilcdc: Use complete_all() to indicate completed palette loading"
- Drop "drm/tilcdc: Call reset() before loading the palette"
- "drm/tilcdc: Load palette at the end of mode_set_nofb()"
  - Just load the palette every time, no runtime_resume hook

Changes since v2:
- Add: "drm/tilcdc: Fix load mode bit-field setting in tilcdc_crtc_enable()"
- Drop: "drm/tilcdc: Free palette dma memory in tilcdc_crtc_destroy()"
- Add: "drm/tilcdc: Add timeout wait for palette loading to complete"
- Add: "drm/tilcdc: Call reset() before loading the palette"
- Add: "drm/tilcdc: Use complete_all() to indicate completed palette loading"
- Add "drm/tilcdc: Enable frame done irq and functionality for LCDC rev 1"
  - Bartosz: Please test if this works! The symptom for not working is
    "timeout waiting for framedone" message when screen is blanked.

Changes since first version of the series:

- Move tilcdc_regs.h changes from "drm/tilcdc: Enable palette loading
  for revision 2 LCDC too" to "drm/tilcdc: Add tilcdc_write_mask() to
  tilcdc_regs.h"

These patches are inspired by this series form Bartosz Golaszewski:
https://www.spinics.net/lists/arm-kernel/msg539629.html

The patches are based on drm-next plus the earlier patches that I plan
to send in a pull request for 4.10. The base + these patches are
pushed here:

https://github.com/jsarha/linux drm-next-tilcdc-for-4.10-wip

file!
