[PATCH 1/2] arm64: dts: rockchip: add node name for RK3588_PD_RKVDEC0/1 and RK3588_PD_VENC0/1

[PATCH 1/2] arm64: dts: rockchip: add node name for RK3588_PD_RKVDEC0/1 and RK3588_PD_VENC0/1

[Shawn Lin]

Thus the board dts files could add property for these nodes.

[PATCH 2/2] arm64: dts: rockchip: Add domain-supply for pd_rkvdec0/1 and pd_venc0/1

[Shawn Lin]

The power domains pd_rkvdec0/1 and pd_venc0/1 depend on two voltage supplies,
vdd_vdenc_s0 and vdd_vdenc_mem_s0. These supplies might be missing or cause probe
deferral. Since the Rockchip power domain management code currently supports managing
only one power supply, and both supplies belong to the same PMIC (making it highly
unlikely for one to be available while the other is not), a practical solution is
implemented.

Both supplies are configured with the boot-on and always-on properties. Only one
of them is assigned as the domain-supply for pd_rkvdec0/1 and pd_venc0/1. This allows
the power domain code to perform a nominal enable operation on this single supply,
thereby successfully acquiring a reference to both supplies (as they are from the same
PMIC). The system then relies on their boot-on and always-on flags to maintain the
correct state.

Crucially, this approach handles cases like probe deferral correctly:
if the PMIC is not yet ready, enabling the power domain will be deferred until the
necessary supplies become available.

Oops, I sent the wrong version. Should remove the this line change.
Will fix it if v2 needed.

just as a question, does the board have problems without these supplies?
Aka, is this a fix for a problem, or "just" future proofing the board?

Ah, I take everything back. The pmdomain patch in
   https://lore.kernel.org/r/1770891364-52147-1-git-send-email-shawn.lin@rock-chips.com
is the actual fix.

With that patch applied all board should work correctly by deferring
the vdec probe until each board adds its domain-supply.

To not cause too much disturbance, this then counts as feature :-)

You should also add pmdomain driver.

I've encountered a similar issue before. 
Finley told me to use the new PMIC, and that would solve the problem. 
Maybe you're using the same old PMIC as I did :)

I don't know what does new PMIC mean? New RK806 driver or new RK806
hardware?

The problem is these power domains rely on voltage supply which could
be probed late after pmdomain driver, then the system enables the PD and
access the IP without PD actually enabled(even w/o voltage supply
enabled).

It is new RK806 hardware. According to Finley, end users are currently using 
this new type of PMIC.

If I'm not mistaken, the new hardware will automatically powers up the supply
corresponding to VDEC/VNEC.

Thanks for the clarification on the hardware update.

I'm currently using the EVB board for SoC bring-up and post-silicon
validation, which I believe carries the old RK806 hardware. It's also
apparent that many developers (as opposed to end users) are still
relying on the old hardware in the field.

Generally speaking, upstream code has no way to distinguish between the 
old and new PMIC variants solely from the DTS, correct? Given this, I
think we should aim to keep both hardware versions workable in the
upstream code.

As far as I know, only early EVBs internal to Rockchip used them.
I think your approach also makes sense :)
