media: mtk-jpegenc: Fix bug in JPEG encode quality selection
The driver uses the upper-bound approach to decide the target JPEG
encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.
Fix the bug by assuming using the best quality in the beginning, and
with trivial refactor to avoid long lines.
Digging into the documentation we find that the DT_ID bitfield is used to
map the six bit DT to a two bit ID code. This value is concatenated to the
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.
commit 3c4ed72a16bc ("media: camss: sm8250: Virtual channels for CSID")
silently fixed the multiplication by four which would give a better
value for the generated CID without mentioning what was being done or why.
Next up I haplessly changed the value back to "dt_id = vc * 4" since there
didn't appear to be any logic behind it.
Hans asked what the change was for and I honestly couldn't remember the
provenance of it, so I dug in.

Several of our upstream and soon-to-be upstream SoC CAMSS dtsi declare
csiphyX as opposed to the older clock name csiX_phy.
Right now the CAMSS code will fail to set the csiphyX clock even if we have
declared it in our list of clocks. For sdm845 and sm8250 we appear to "get

The right approach here is to set the clock when it is declared. If a SoC
doesn't require or a SoC driver implementer doesn't think we need, then the
clock ought to simply be omitted from the clock list.
Include csiphyX in the set of permissible strings which will subsequently
lead to the csiphyX clock being set during csiphy_set_clock_rates() phase.

The csiphyX_timer and csiX_phy values need not be hard-coded. We can
functionally decompose the string matching inside of a loop.
Static string values are brittle, difficult to extend and not required
anyway since the camss->res->csiphy_num value informs us of the number
of CSIPHYs and hence the set of potential clocks for a given CSIPHY.
In simple terms if we have five CSIPHYs we can have no more and no less
than five csiphy_timer clocks. Similarly csi_phy core clocks have a 1:1
relationship with the PHY they clock.

We need to support the following clock name formats

media: qcom: camss: Remove special case for VFE get/put
From sdm845 onwards we need to ensure the VFE is powered on prior to
switching on the CSID.
Currently the code tests for sdm845, sm8250 and then does get/set. This is
not extensible and it turns out is not necessary either since vfe_get and
vfe_set reference count.
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.

This is useful for higher resolution sensors like the 2560x1920 ov5693
sensor.
Note the highest resolutions added here are 1920x<height> because
the atomisp firmware does not support widths > 1920 with the default
asd->run_mode->val == ATOMISP_RUN_MODE_PREVIEW setting.

media: atomisp: Change atomisp_enum_framesizes() too small cut off from 2/3th to 5/8th
Change atomisp_enum_framesizes() cut off for too small resolutions
from 2/3th to 5/8th this results in more resolutions being available
with some sensors.
E.g. this allows using 800x600 with a 1280x960 sensor.

media: atomisp: Clamp width to max 1920 pixels when in ATOMISP_RUN_MODE_PREVIEW
The pipeline firmware-binaries used in previed mode have
ia_css_binary_xinfo.output.max_width set to 1920.
This causes ia_css_binary_find() to fail when trying to set a higher
resolution resulting in the dump_stack() call in ia_css_binary_find()
triggering and resulting in the try_fmt() or set_fmt() IOCTL failing.
Fix this by clamping the width to max 1920 when in preview mode.

media: atomisp: sh_css_internal: sh_css_params: Unifying sh_css_sp_group data structure
Since some parts of the data structure elements are determined in compile
time, the configuration data structure should be compiled for both two
ISP models. In order to set the configuration for both ISP models in
runtime, The sh_css_sp_group is unified to one data structure for the
configuration to ensure the data structure can be used for both ISP2400
and 2401 in runtime. Also, the unused codes for debug purpose are removed.
Form the aspect of ISP setting, the length and the content of the
configuration structure for ISP2400 and ISP2401 are different. So, we
need to pick up the necessary part of sp_group configuration for both
models and then copy those parts into a temporary buffer. This buffer
is finally written to the ISP with the corresponding length.
