irqchip/riscv-intc: remove user selectability of RISCV_INTC

2022-12-08T23:57:07+00:00

Since commit e71ee06e3ca3 ("RISC-V: Force select RISCV_INTC for CONFIG_RISCV") the driver has been enabled at the arch level - and is mandatory anyway. There's no point exposing this as a choice to users, so stop bothering.

irqchip/sifive-plic: remove user selectability of SIFIVE_PLIC

2022-12-08T23:57:06+00:00

The SiFive PLIC driver is used by all current implementations, including those that do not have a SiFive PLIC. The current driver supports more than just SiFive PLICs at present and, where possible, future PLIC implementations will also use this driver. As every supported RISC-V SoC selects the driver directly in Kconfig.socs there's no point in exposing this kconfig option to users. The Kconfig help text, in its current form, is misleading. There's no point doing anything about that though, as it will no longer be user selectable. Remove it.

irqchip/al-fic: Drop obsolete dependency on COMPILE_TEST

2022-11-26T13:29:42+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

irqchip/loongson-htvec: Add ACPI init support

2022-11-26T13:07:47+00:00

HTVECINTC stands for "HyperTransport Interrupts" that described in Section 14.3 of "Loongson 3A5000 Processor Reference Manual". For more information please refer Documentation/loongarch/irq-chip-model.rst. Though the extended model is the recommended one, there are still some legacy model machines. So we add ACPI init support for HTVECINTC.

irqchip: IMX_MU_MSI should depend on ARCH_MXC

2022-10-12T07:43:59+00:00

The Freescale/NXP i.MX Messaging Unit is only present on Freescale/NXP i.MX SoCs. Hence add a dependency on ARCH_MXC, to prevent asking the user about this driver when configuring a kernel without Freescale/NXP i.MX SoC family support. While at it, expand "MU" to "Messaging Unit" in the help text.
