This series enables support for 6xx venus encode/decode on sc7280.

The driver changes are dependent on [1]yaml and [2]dts patches.

[1] https://patchwork.kernel.org/project/linux-arm-msm/list/?series=484019
[2] https://patchwork.kernel.org/project/linux-arm-msm/list/?series=484727

Changes since v3:
 - addressed comments on v3 (stanimir).
 - rebased the changes on latest media tree.

Dikshita Agarwal (7):
  venus: firmware: enable no tz fw loading for sc7280
  media: venus: core: Add sc7280 DT compatible and resource data
  media: venus: Add num_vpp_pipes to resource structure
  media: venus: hfi: Skip AON register programming for V6 1pipe
  venus: vdec: set work route to fw
  media: venus: helpers: update NUM_MBS macro calculation
  media: venus: Set buffer to FW based on FW min count requirement.

V6 HW can have vpp pipes as 1 or 4, add num_vpp_pipes
to resource struture to differentiate.

AON register programming is used to set NOC to low
power mode during V6 power off sequence. However
AON register memory map is not applicable to 1pipe,
hence skipping AON register programming.

- Get the min buffer count required by FW from source event change
  and use the same value to decide actual buffer count and for
  buffer size calculation.
- Setup DPB and OPB buffers after session continue incase of
  reconfig.

Could you help me understand what is the difference between both
calculations? IMO this patch should only change NUM_MBS_720P and
NUM_MBS_4K macros.

This change just makes indentation wrong and also it is not related to
the patch subject.

We are updating the calculation here to match with the calculation used 
in Macro.
AFAIK, we were seeing a size mismatch for a resolution with the old 
calculation.

I think it can be dropped.
