[PATCH 0/8] Initial SM8150 and SM8250 DPU bringup

[PATCH 0/8] Initial SM8150 and SM8250 DPU bringup

[Jonathan Marek]

These patches bring up SM8150 and SM8250 with basic functionality.

Tested with displayport output (single mixer, video mode case).

I will send patches later to add support for merge3d and dual DSI
configurations, and possibly also patches to fix command mode on
these SoCs (note it is also currently broken for SC7180).

Jonathan Marek (8):
  drm/msm/dpu: use right setup_blend_config for sm8150 and sm8250
  drm/msm/dpu: update UBWC config for sm8150 and sm8250
  drm/msm/dpu: move some sspp caps to dpu_caps
  drm/msm/dpu: don't use INTF_INPUT_CTRL feature on sdm845
  drm/msm/dpu: set missing flush bits for INTF_2 and INTF_3
  drm/msm/dpu: intf timing path for displayport
  drm/msm/dpu: add SM8150 to hw catalog
  drm/msm/dpu: add SM8250 to hw catalog

[PATCH 1/8] drm/msm/dpu: use right setup_blend_config for sm8150 and sm8250

[Jonathan Marek]

All DPU versions starting from 4.0 use the sdm845 version, so check for
that instead of checking each version individually. This chooses the right
function for sm8150 and sm8250.

[PATCH 2/8] drm/msm/dpu: update UBWC config for sm8150 and sm8250

[Jonathan Marek]

Update the UBWC registers to the right values for sm8150 and sm8250.

This removes broken dpu_hw_reset_ubwc, which doesn't work because the
"force blk offset to zero to access beginning of register region" hack is
copied from downstream, where mapped region starts 0x1000 below what is
used in the upstream driver.

Also simplifies the overly complicated change that was introduced in
e4f9bbe9f8beab9a1ce4 to work around dpu_hw_reset_ubwc being broken.

[PATCH 3/8] drm/msm/dpu: move some sspp caps to dpu_caps

[Jonathan Marek]

This isn't something that ever changes between planes, so move it to
dpu_caps struct. Making this change will allow more re-use in the
"SSPP sub blocks config" part of the catalog, in particular when adding
support for SM8150 and SM8250 which have different max_linewidth.

This also sets max_hdeci_exp/max_vdeci_exp to 0 for sc7180, as decimation
is not supported on the newest DPU versions. (note that decimation is not
implemented, so this changes nothing)

[PATCH 4/8] drm/msm/dpu: don't use INTF_INPUT_CTRL feature on sdm845

[Jonathan Marek]

The INTF_INPUT_CTRL feature is not available on sdm845, so don't set it.

This also adds separate feature bits for INTF (based on downstream) instead
of using CTL feature bit for it, and removes the unnecessary NULL check in
the added bind_pingpong_blk function.

Fixes: 73bfb790ac786ca55fa2786a06f59 ("msm:disp:dpu1: setup display datapath for SC7180 target")

[PATCH 7/8] drm/msm/dpu: add SM8150 to hw catalog

[Jonathan Marek]

This brings up basic video mode functionality for SM8150 DPU. Command mode
and dual mixer/intf configurations are not working, future patches will
address this. Scaler functionality and multiple planes is also untested.

[PATCH 8/8] drm/msm/dpu: add SM8250 to hw catalog

[Jonathan Marek]

This brings up basic video mode functionality for SM8250 DPU. Command mode
and dual mixer/intf configurations are not working, future patches will
address this. Scaler functionality and multiple planes is also untested.

It seems you missed sending a patch adding support for 
DPU_SSPP_SMART_DMA_V2_5. Could you please point to it?

There are no other changes related to that, the driver never checks 
smart_dma_rev and the correct version number is only set for when the 
driver supports it (if ever).
