Subject: [PATCH v5 0/6] media: qcom: camss: Add sc8280xp support
V5:
- Fixes the lower case 0x0c to 0x0C not sure how Konrad even saw this.
- Drops frequency table to just individual frequencies not full array of
opps - Konrad
- As explained doesn't change the finding of frequencies.
Current array size will ensure testing if (freq[x]) succeeds though I
do agree this should be changed up.
Plan to restructure struct params for specificity to VFE, CSID and will
incorporate this change then.

- Reset sequence
Right now the reset works. I agree qcom's downstream has more stuff in
it. I've logged a task to evaluate expansion of the reset and to test
across multiple platforms.
For now not required for this drop.
- _src clocks
One assumes the reason at some stage in time we didn't have SET_PARENT in
our CAMCC which meant setting _src clocks was necessary. In any case it
ought not to be necessary now.
Removing the _src from existing platforms should be trivial however we
might find that as a result some of the CAMCC drivers need to be updated.
That obviously is a separate series.

Link to tree: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/b4/camss-sc8280xp-v5
V4:
- Drops all _src clocks and _SRC indexes in series.
True enough the CAMCC driver has all of the appropriate SET_PARENT flags
so there's no need to represent _src clocks. - Konrad
- I've opted not to split C-PHY and D-PHY init sequences up unless/until
we have a C-PHY init sequence upstream. - bod/Konrad

V3:
- Strip pointer to dependencies from yaml patch

- Rebase to capture is_lite flag from named power-domain series
- Amends commit log of final patch to give more detail on rename - Konrad
- Opted not to change switch() statements with returns. - bod/Konrad

V1:
sc8280xp is the SoC found in the Lenovo X13s. This series adds support to
bring up the CSIPHY, CSID, VFE/RDI interfaces.
A number of precursor patches make this series smaller overall than
previous series.
sc8280xp provides
- 4 x VFE, 4 RDI per VFE
- 4 x VFE Lite, 4 RDI per VFE
- 4 x CSID
- 4 x CSID Lite
- 4 x CSI PHY
I've taken the yaml from a dtsi series and included it here since 1) I sent
the yaml to the wrong person and 2) it already has RB from Krzysztof.
Requires CAMCC for sc8280xp which applies to qcom/clk-for-6.7:
https://lore.kernel.org/linux-arm-msm/20231026105345.3376-1-bryan.odonoghue@linaro.org/
b4 shazam 20231026105345.3376-1-bryan.odonoghue@...aro.org
Requires the named power-domain patches which apply to media-tree/* :
https://lore.kernel.org/linux-arm-msm/20231101-b4-camss-named-power-domains-v3-5-bbdf5f22462a@linaro.org/

To use the camera on x13s with say Google Hangouts or Microsoft Teams you
will need to
1. Run Firefox
2. Update about:config to enable pipewire
3. Use this WIP version of libcamera
