irqchip/qcom: Add defaults for desired SoC drivers

2026-09-04T13:34:33+00:00

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.

irqchip/irq-imgpdc: Remove unused driver

2026-07-06T21:22:56+00:00

The irq-imgpdc driver is controlled by CONFIG_IMGPDC_IRQ, which cannot be enabled. It used to be selected by CONFIG_SOC_TZ1090, but that was removed along with the metag architecture in Linux 4.17.

irqchip/ast2700-intc: Add AST2700-A2 support

2026-04-30T10:53:03+00:00

The AST2700 interrupt fabric is shared by multiple integrated processors (PSP/SSP/TSP/BootMCU), each with its own interrupt controller and its own devicetree view of the system. As a result, interrupt routing cannot be treated as fixed: the valid route for a peripheral interrupt depends on which processor is consuming it. The INTC0 driver models this by creating a hierarchical irqdomain under the upstream interrupt controller selected by the interrupt-parent property in the devicetree. Information derived from this relationship is incorporated into the route resolution logic for the controller. The INTC1 driver implements the banked INTM-fed controller and forwards interrupts toward INTC0, without embedding assumptions about the final destination processor.
