[PATCH 1/4] ARM: dts: qcom: msm8974: add ocmem clock to GPU

[Dmitry Baryshkov]

To get GPU working with the OCMEM, the oxili_ocmemgx_clk clock should be
enabled. Pass it to the GPU to get it to work on apq8074/msm8974 boards.

[PATCH 2/4] ARM: dts: qcom: apq8074-dragonboard: Set DMA as remotely controlled

[Dmitry Baryshkov]

Add the qcom,controlled-remotely property for the blsp2_bam
controller node. This board requires this, otherwise the board stalls
during the boot for some reason (most probably because TZ mishandles the
protection error and keeps on looping somewhere inside).

[PATCH 3/4] ARM: dts: qcom: apq8074-dragonboard: enable adsp and MSS

[Dmitry Baryshkov]

Enable ADSP and Modem DSPs on APQ8074 dragonboard. The MSS region
differs from the one defined in the msm8974, so it overriden locally.

The modem is specified use mba.mbn instead of mbn.b00 (for the sake of
similarity with other platforms). This requires a patch for remoteproc
to be applied [1].

Uhh.. this clock should be managed by RPM with:

type = MEM
id = 2

just like it's defined for 8994 today.

Could you try adding it in rpmcc and confirming?

Looks like a common theme.. sony-rhine boards also have the DMA
enabled *and* need this property.. perhaps it's a SoC-wide (or
at least SoC-and-fw-distribution-wide) issue?

There is an RPM_SMD_OCMEMGX_CLK clk already, it is a bus clock for the 
ocmemnoc.

Can you possibly be more specific here?

On 8974 RPM_SMD_OCMEMGX_CLK is a core clock for ocmem and a bus clock 
for ocmemnoc.

On 8994 this clocks is just a core clock for ocmem, there is no ocmemnoc.

Can you possibly be more specific here?

On 8974 RPM_SMD_OCMEMGX_CLK is a core clock for ocmem and a bus clock 
for ocmemnoc.

On 8994 this clocks is just a core clock for ocmem, there is no ocmemnoc.

I think the problem is that they are not level-voted on this platform,

The ocmemnoc bus is managed internally, the rpm clock is not used for scaling,
only to make sure the NIU is clocked for ocmem node access.

It's "scaled" with the ocmem-slv node, but the code never sets any rate,
only calls clk_get.

It's there, named "fab-ovirt" and on 8994 it's actually used for scaling.

This looks like a strange history. Especially granted 338d51889851 
("Revert "dts: msm8974: Add blsp2_bam dma node"") and d44cbb1e9ca3 
("Revert "Revert "dts: msm8974: Add blsp2_bam dma node""")

And, of course, 
https://lore.kernel.org/linux-arm-msm/CAJAp7Oi33=kraAiU337JdFJZbuKZEVoCtY4FfAv_RgiWVmz+sw@mail.gmail.com/

Note, 338d51889851 mentions non-dragonboard boards. This makes me think 
that for some of the dragonboards/firmware combos this device was 
working as is, without controlled remotely. I could not get 'the latest 
bootloader package' (if there was one), so I'm stuck with what I have on 
my board. However there is no guarantee that it is the latest and 
greatest stuff.

Thus said, for this patch I decided to follow the rhino example and add 
this to the board file. Unless Bjorn (or anybody else remembering those 
times) can advise us.

Hmm. Indeed. In msm8974-regulators I see both voltage and corner entries

Checked. Only CX and GFX (yes, MX not included) are enabled as corners 
in vendor dtsi. So this probably doesn't gain us a lot.

I did a check. Implementing CX as a powerdomain here makes things
worse for now. We should first teach mss/pas/etc drivers to properly
handle the case when there is a single power-domain, which should be
unbound after staring the DSP Consider e.g. ADSP and CDSP on sm8150 or
CDSP on sm8250. But that's definitely a topic for a different patch
series. After that we can consider landing msm8974_genpd.
