Merge tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

2023-02-26T19:47:26+00:00

Pull media updates from Mauro Carvalho Chehab:

 - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
   stkwebcam, tm6000, vpfe_capture and zr364xx

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

 - av7110 returned from staging/deprecated/ to staging/ as we're not
   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
   one after -rc1, giving some time to experience the API and eventually
   have changes during the next development cycle

 - New sensor drivers: imx296, imx415, ov8858

 - Atomisp had lots of changes, specially on its sensor's interface,
   making atomisp sensor drivers closer to normal sensor drivers

 - media controller kAPI has gained some helpers to traverse pipelines

 - uvcvideo now better support power line control

 - lots of bug fixes, cleanups and driver improvements

media: renesas: vsp1: Change V3U to be gen4

2023-01-20T15:46:00+00:00

V3U is actually gen4, not gen3. The same IP is also used in the
(not-yet-supported) V4H.

Change VI6_IP_VERSION_MODEL_VSPD_V3U to VI6_IP_VERSION_MODEL_VSPD_GEN4,
to represent the model correctly. V3U and V4H can still be
differentiated, if needed, with the VI6_IP_VERSION_SOC_xxx.

Also mark VI6_IP_VERSION_MODEL_VSPD_GEN4 as gen 4 in vsp1_device_info,
and update the code to correctly match for gen 4.

media: rzg2l-cru: fix a test for timeout

The test for if the loop timed out is wrong and Smatch complains:

    drivers/media/platform/renesas/rzg2l-cru/rzg2l-csi2.c:411 rzg2l_csi2_mipi_link_disable()
    warn: should this be 'timeout == -1'

Let's change it to a preop loop instead of a post op loop.

ret is unnecessarily shadowed, meaning the assignments to ret within the
first 'if (enable)' block are only applied to the inner scope, not the
outer one as intended. Remove the shadowing to fix the warnings and make
everything work correctly.

media: rcar-vin: Add support for Gen3 UDS (Up Down Scaler)

2022-11-25T11:00:26+00:00

Add support for the UDS (Up Down Scaler) found in some Gen3 SoCs.

Not all Gen3 SoCs have scalers, and for those that do it's only
available to the master node of each VIN group. The setup for which SoCs
and nodes have access to a scaler are dealt with at probe time and then
function transparently reusing the schema from the already present Gen2
scaler.
