[PATCH DNI v2 00/11] media: rcar-fcp, vsp1: Enable on R-Car X5H

[Paul Elder]

This series is based on Geert's
"topic/rcar-x5h-ironhide-scmi-cpg-mdlc-remapping-v3" branch [0]. A
branch including this series is available here [1].

This series enables the FCPV{B,I,D} and the VSP{B,I,D} blocks on the Renesas
R-Car X5H SoC.

This has been tested on an Ironhide with the vsp-tests test suite [2].
VSPI:
145 tests: 138 passed, 0 failed, 7 skipped
VSPB:
115 tests: 104 passed, 0 failed, 11 skipped
VSPD (a):
114 tests: 99 passed, 0 failed, 15 skipped

VSPD (b) hangs on the tests, so that needs some investigation.

The first couple patches add clocks that are used by the FCP and VSP,
but as the upstream X5H CPG driver is barebones at the moment and we
don't yet ensure that the parents are enabled, these are marked as DNI
for the moment.

The last patch checks the device revision and prints it, which is useful
for debugging but is unnecessary processing for driver operation so it
is marked as DNI as well.

There was some odd behavior with the clocks, where from what I
understood was that the clocks for the FCPV{B,I} and VSP{B,I} are
always-on, but the tests would hang unless I explicitly enabled...  the
always-on clock (or fsleep). Then after I removed the patch that
explicitly enabled the always-on clock everything ran fine. Just
reporting that this happened just in case it's relevant.

[PATCH DNI v2 01/11] dt-bindings: clock: renesas,r8a78000-cpg: Add CPG_SGD4_VIO_DP_{TX,OTHER}

[Paul Elder]

Add the CPG_SGD4_VIO_DP_TX and CPG_SGD4_VIO_DP_OTHER clocks. The former
is used by FCPV{B,D,I} and VSPD while the latter is used by VSP{B,I} on
the Renesas R-Car X5H.

[PATCH DNI v2 02/11] clk: renesas: r8a78000: Add clock for FCPV and VSP for SCP FW SDKv4.36

[Paul Elder]

Add clocks for the FCPV{B,D,I} and VSP{B,D, I}. They each have one clock
from an option of two: a 1066MHz and a quarter-divided 266MHz. As we
already have support for the 266MHz one, add just those for now.

This also doesn't seem to be a candidate for upstream yet as it depends
on WIP patches for the MDLC driver.

[PATCH v2 07/11] media: vsp1: Support full VSPB on R-Car M3-W, M3-N and E3

[Paul Elder]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

The M3-W, M3-N and E3 SoCs integrate a VSPB that reports the same
version ID as the VSPBD in the H3 and H3-N, but includes additional
entities compared to the VSPBD. The VSPBD device entry in the driver
matches on the version ID only, which results in the VSPB being handled
as a VSPBD. The driver therefore doesn't support the CLU, LUT and HGO
entities in the M3-W, M3-N and E3 SoCs.

To fix it, split the device entry in two, one for the VSPBD with an
additional SoC ID match, and one for the VSPB. The VSPBD entry needs to
be listed first, otherwise the VSPB entry will match on H3 and H3-N as
well.

The VI6_IP_VERSION_MODEL_VSPBD_GEN3 macro is renamed to
VI6_IP_VERSION_MODEL_VSPB_GEN3 to indicate that the VSPBD is the special
case.

[PATCH v2 08/11] media: vsp1: Document X5H SoC ID

[Paul Elder]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

The R-Car X5H uses 0x09 as the SoC ID in the version register. Document
is with a macro, as done for other R-Car SoCs.

[PATCH v2 09/11] media: vsp1: Add device info entries for VSPD on X5H

[Paul Elder]

Add device info entries for the VSPD so that the driver can match on the
VSPD on the X5H and handle it slightly different hardware configuration.

On the X5H there are two variants, the VSPD (a) and VSPD (b). As the (b)
version has a separate version number, add that as well.

This is not quite correct, this VSP has 8 UIFs (from UIF0 to UIF7).
However, not only does the driver support at most two UIFs, it hardcodes
usage of one UIF per LIF, and starts at UIF4. Declaring two UIFs here is
fine for the time being, but a comment would be nice.

I think that should be VI6_IP_VERSION_MODEL_VSPDB_GEN5.

And you can drop the soc match for now, no other SoC uses the version
model ID 0x20.

[PATCH v2 10/11] media: rcar-fcp: Handle resets

[Paul Elder]

On some versions of the FCP, such as the one on the X5H, reset control
is required to operate the FCP. Add support for handling resets
optionally, to continue supporting versions that do not require it.

Signed-off-by: Paul Elder <paul.elder+renesas@ideasonboard.com>

Changes in v2:
- handle errors

[PATCH DNI v2 11/11] media: rcar-fcp: Check device revision at probe time

[Paul Elder]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Verify that the device revision register reports a valid value,
otherwise reject the device.

Changes since v2:

- Add FCP type information
- Reject devices with an unsupported version

Changes since v1:

- Use devm_platform_ioremap_resource()
