[PATCH v2 0/4] Add support for PDC interrupt controller for sm8150

[Bhupesh Sharma]

Changes since v1:
-----------------
- v1 can be found here: https://lore.kernel.org/linux-arm-msm/20220119203133.467264-1-bhupesh.sharma@linaro.org/
- Collect ACK from Rob on PATCH 1/4.
- Address review comments from Maulik.

This patchset adds the support for PDC interrupt controller found
on sm8150 SoCs from Qualcomm.

Here we add the device-tree bindings, pinctrl driver support
and the dts support for the same.

[PATCH v2 2/4] pinctrl: qcom: sm8150: Specify PDC map

[Bhupesh Sharma]

Specify the PDC mapping for SM8150, so that gpio interrupts are
properly mapped to the wakeup IRQs of the PDC.

When I look at the platform documentation I get the impression that this
should be: <0 480 94>, <94 609 32>;

Can you confirm that the last signal is correctly described?

Yes, I confirmed by double checking the entries in downstream 'pdc-sm8150.c'.
The pdc pins in the 2nd range start from 94 and end at 124, so a total
of 31 entries, but both 94 and 124 pins included.

Or, am I missing something?

Thanks,
Bhupesh

Thanks for double checking, let's follow the downstream kernel.
I will merge the patch as you proposed it.

[PATCH v2 4/4] arm64: dts: qcom: sm8150: Add PDC as the interrupt parent for tlmm

[Bhupesh Sharma]

Several wakeup gpios supported by the Top Level Mode Multiplexer (TLMM)
block on sm8150 can be used as interrupt sources and these interrupts
are routed to the PDC interrupt controller.

So, specify PDC as the interrupt parent for the TLMM block.

Looks good to me, but I need Bjorns ACK before merging this.
