2022-06-10ARM: meson: Fix refcount leak in meson_smp_prepare_cpusMiaoqian Lin1-0/+2
of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.

2020-02-29ARM: meson: Drop unneeded select of COMMON_CLKGeert Uytterhoeven1-1/+0
Support for Amlogic Meson SoCs depends on ARCH_MULTI_V7, and thus on ARCH_MULTIPLATFORM. As the latter selects COMMON_CLK, there is no need for ARCH_MESON to select COMMON_CLK.

2019-02-06ARM: meson: remove COMMON_CLK_AMLOGIC selectionJerome Brunet1-1/+0

2018-12-10ARM: meson: select HAVE_ARM_TWD and ARM_GLOBAL_TIMERMartin Blumenstingl1-0/+2
The 32-bit Meson SoCs use multiple Cortex-A9 (Meson8 and Meson8m2) or Cortex-A5 (Meson8b) CPU cores. These come with the "ARM global timer" and "Timer-Watchdog" (aka TWD, which provides both a per-cpu local timer and watchdog). Selecting ARM_GLOBAL_TIMER and HAVE_ARM_TWD allows us to add the timers to the SoC.dtsi files. Signed-off-by: Martin Blumenstingl <[email protected]> Signed-off-by: Kevin Hilman <[email protected]>
2018-05-23ARM: meson: merge Kconfig symbol MACH_MESON8B into MACH_MESON8Martin Blumenstingl1-8/+1
Currently there are no differences between the MACH_MESON8 and MACH_MESON8B Kconfig symbols (except the help text). Since both platforms are very similar (Meson8b being a slightly updated, cost-reduced version of Meson8 which even shares some peripherals with Meson8m2) no notable differences are expected in the future either.

2018-05-10ARM: meson: add support for the Meson8m2 SoCsMartin Blumenstingl2-1/+2
Add the newly introduced compatible string for the Meson8m2 SoC. The existing Meson8 Kconfig entry is updated to also provide support for the Meson8m2 SoCs. The Meson8m2 SoC is mostly identical to the Meson8 SoC with just a few peripherals being updated. Both SoCs currently share the same pinctrl, clock and GPIO IRQ bindings. Thus the existing Kconfig entry is re-used to avoid duplication (the only cost is building a few extra DTBs).

2016-06-03ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBLinus Walleij1-1/+1
This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

2015-12-01ARM: use "depends on" for SoC configs instead of "if" after promptMasahiro Yamada1-1/+2
Many ARM sub-architectures use prompts followed by "if" conditional, but it is wrong. Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct. As a good side effect, this commit fixes some entries over 80 columns (mach-imx, mach-integrator, mach-mbevu).
