[PATCH 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.

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 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.  QCOM_MPM is used only on ARM64 SoCs, thus
there is no point in proposing this option for 32-bit Qualcomm platforms
making kernel configurators life easier.

This is only because no one wired it up, almost/all 32-bit SoCs
have one too

Ah, then I will not restrict it per arm64.

QCOM_MPM is used on ARM32 bit targets, SoC like mdm9607

[PATCH 2/3] irqchip/qcom: Add defaults for desired arm64 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.

[PATCH 3/3] arm64: defconfig: Drop redundant Qualcomm irqchip entries

[Krzysztof Kozlowski]

QCOM_PDC and QCOM_MPM are enabled by default.

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