Subject: [PATCH v6 0/6] media: qcom: camss: Add sc8280xp support

V6:
- Add of camss.yaml passes on linux-stable/master as at
commit: ff93872a9c61 ("clk: qcom: camcc-sc8280xp: Add sc8280xp CAMCC")

- Fixed IFE/VFE comment discongruity - Konrad

- Per my explaination I don't propose to change IFE/VFE naming since
they are the same thing.

SFE blocks should be named SFE though, not IFE/VFE

- Referring to Konrad's other comments on IFE/VFE naming
https://lore.kernel.org/all/[email protected]/#t

The next two changes I intend not covered in this SoC series

a) Completing the conversion to named power-domains
b) Camera NOC => OPPs for the camera NoC

Not covered in this series though.

Link to v5: https://lore.kernel.org/r/[email protected]
Link to tree: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/b4/camss-sc8280xp-v6
Bootable: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/sc8280xp-v6.8-rc4-camss?ref_type=heads

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.
Link: https://lore.kernel.org/all/[email protected]

- 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 v4: https://lore.kernel.org/r/[email protected]
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

- b4 trailes --update -> + Konrad's Acks

Link to tree: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/b4/camss-sc8280xp-v4

V3:
- Strip pointer to dependencies from yaml patch

b4 base:
https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/b4/camss-sc8280xp-v3

V2:
- 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

Requires CAMCC for sc8280xp which applies to qcom/clk-for-6.7:

https://lore.kernel.org/r/[email protected]

b4 base:
https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/b4/camss-sc8280xp-v2

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/[email protected]/
b4 shazam [email protected]

Requires the named power-domain patches which apply to media-tree/* :

b4 shazam 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
https://gitlab.freedesktop.org/camera/libcamera-softisp

Subject: [PATCH v6 2/6] media: qcom: camss: csiphy-3ph: Add Gen2 v1.1 two-phase MIPI CSI-2 DPHY init

Add a PHY configuration sequence for the sc8280xp which uses a Qualcomm
Gen 2 version 1.1 CSI-2 PHY.

The PHY can be configured as two phase or three phase in C-PHY or D-PHY
mode. This configuration supports two-phase D-PHY mode.
