[PATCH v2 0/3] irqchip: qcom: Add sane defaults and drop defconfig

[Krzysztof Kozlowski]

Merging
=======
1. First irqchip patches via irqchip.
2. defconfig next cycle via Qualcomm SoC tree.

Changes in v2:
- Do not restrict MPM to arm64.
- Enable MPM by default only on arm64, because there is no 32-bit
  upstream user.
- Link to v1: https://patch.msgid.link/20260727-irqchip-qcom-defaults-v1-0-ed80ad83ca53@oss.qualcomm.com

We should not be really asking whether to enable internal SoC drivers.
This is an obvious choice.

And if it does not seem obvious, then consider [1].

[PATCH v2 1/3] irqchip/qcom: Enable compile testing for QCOM_PDC and QCOM_MPM

[Krzysztof Kozlowski]

QCOM_PDC and QCOM_MPM do not reference any architecture code, thus
should be compile-testable.

[PATCH v2 2/3] irqchip/qcom: Add defaults for desired SoC drivers

[Krzysztof Kozlowski]

QCOM_PDC and QCOM_MPM are essential for booting up SoCs and are not
really optional for a given platform.  Kernel should not ask users
choice of drivers when that choice is obvious and known to the
developers that answer should be 'yes' or 'module'.

Enable these by default whenever a kernel for Qualcomm SoC is built.
The change has no impact on arm64 defconfig, but will enable QCOM_PDC
for 32-bit ARM multi_v7_defconfig and qcom_defconfig, which is desired
because SDX55 uses it.

QCOM_MDM is used by 32-bit Qualcomm SoCs, but there is no in-tree user
of it, so it does not have to be enabled by default.

Depends on previous patch - this can wait a cycle and go via Qualcomm
SoC tree later.
