Digging into the documentation we find that the DT_ID bitfield is used to

VC bitfield to create a CID value. DT_ID is the two least significant bits
of CID and VC the most significant bits.

Originally we set dt_id = vc * 4 in and then subsequently set dt_id = vc.

Next up I haplessly changed the value back to "dt_id = vc * 4" since there

doesn't require or a SoC driver implementer doesn't think we need, then the

Include csiphyX in the set of permissible strings which will subsequently

At the moment we declare vfe_lite0 and vfe_lite1 for sm8250 but never set

We need to support the following clock name formats

media: qcom: camss: Assign the correct number of RDIs per VFE

Each Video Front End - VFE - has a variable number of Raw Data Interfaces -
RDIs associated with it.

The CAMSS code started from a naive implementation where a fixed define was
used as a control in a for(){} loop iterating through RDIs.

That model scales badly. An attempt was made with  VFE_LINE_NUM_GEN2 and
VFE_LINE_NUM_GEN1 to differentiate between SoCs but, the problem with that
is "gen1" and "gen2" have no meaning in the silicon. There is no fixed
constraint in the silicon between VFE and RDI, it is entirely up to the SoC
designers how many VFEs are populated and how many RDIs to associate with
each VFE.

As an example sdm845 has VFE version 175 and sm8250 VFE version 480.
sdm845 has 2 VFEs with 4 RDIs and 1 VFE Lite with 4 RDIs.
sm8250 has 2 VFEs with 3 RDIs and 2 VFE Lite with 4 RDIs.

Clearly then we need a more granular model to capture the necessary data.

The defines have gone away to be replaced with per-SoC data but, we haven't
populated the parameter data with the real values.

Let's call those values out now

msm8916:
1 x VFE
3 x RDI per VFE (not 4)

msm8996:
2 x VFE
3 x RDI per VFE (not 4)

sdm660:
2 x VFE
3 x RDI per VFE (not 4)

sdm845:
2 x VFE
4 x RDI per VFE (not 3)
1 x VFE Lite
4 x RDI per VFE Lite (not 3)

sm8250:
2 x VFE
3 x RDI per VFE (not 4)
2 x VFE Lite
4 x RDI per VFE Lite

This more complex and correct mapping was not possible prior to passing
values via driver data. Now that we have that change in place we can
correctly map VFEs to RDIs for each VFE.

media: qcom: camss: Pass line_num from compat resources

line_num indicates the number of RDI - raw data interface channels which
are associated with a given IFE/VFE - image/video front end.

On several SoCs the RDI number is not static for each VFE - for example
on sm8250 VFE Lite has four RDIs where regular VFE has three.

Assigning line_num statically in the subdev_init() phase initialises
each VFE to the lower number, meaning in practical terms that we are
lobbing off one RDI on some VFEs.

Interrupt handling uses static for (i = RDI0; i < RDI2; i++) {} in some
of our VFE blocks but this can't work for situations where we have a
mixture of VFE @ 3 RDI and VFE-lite @ 4 RDI blocks.

First step to remediate is to pass line_num from a compat string
controlled data-structure and do so on a per-VFE basis.

Later patches will assign the correct number of RDI blocks per VFE.

media: qcom: camss: Pass remainder of variables as resources

All the rest of the changes are rote camss->variable to

The original mipi_format_t represents the MIPI format settings for both
atomisp with the same name and the enum member was controlled by #if

enum should be individually defined for them.

Since the format type is redefined, the format setting function
ia_css_isys_set_fmt_type() should be reworked for ISP2400 and ISP2401
called ia_css_isys_2400_set_fmt_type() and ia_css_isys_2401_set_fmt_type()
.

Additionally, the function called is_mipi_format_yuv420() isn't used by any
functions so it can be removed.
