[PATCH v3 0/7] media: venus: Enable venus support on sc7280

[Dikshita Agarwal]

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 v2:
 - no longer considering client buffer requirement to calculate
   output buffer min count.
 - addressed comments on v2 (stanimir).

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.

[PATCH v3 4/7] media: venus: hfi: Skip AON register programming for V6 1pipe

[Dikshita Agarwal]

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.

[PATCH v3 7/7] media: venus: Set buffer to FW based on FW min count requirement.

[Dikshita Agarwal]

- 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.

No need to initialize ret to zero.

Could you add a comment why HFI_BUFFER_INTERNAL_SCRATCH_1 is included in
condition and not included in below 'if' condition?

Also in regards to inst->fw_min_cnt, can we pass fw_min_cnt as input to
get_bufreq via 'req' structure, i.e.

req.count_min = inst->fw_min_cnt;

ret = venus_helper_get_bufreq(inst, type, &req);

inst->fw_min_cnt = req.count_min

?

'struct venus_inst' members, i.e. platform_get_bufreq() is not supposed
to change anything from input 'inst' argument.

Hi Dikshita,

Could you please rebase the patchset on top of current
