The gpio patches are mostly based on Wesley's patch. The patchset also adds hierarchy irq domain support as it is required by this gpio driver. This patchset is based on Linux 5.4-rc6 and tested on HiFive Unleashed board Changes: v2 vs v1: - Add patch to introduce irq_domain_translate_onecell() and use it in the sifive PLIC driver - Drop the usage of own locks, instead use internal bgpio_locks - Consistently use regmap for register access throughout the gpio code - Convert the GPIO DT documentation into a json schema - Other minor changes based upon feedback received on v1 v1 vs RFC: Incorporated below changes as suggested by Linus Walleij on RFC version of this patchset[0] - Dropped PWM patches as they are already merged. - Include "GPIO_GENERIC" and "REGMAP_MMIO" in Kconfig select option - Remove unwanted inclusion of header files - Use regmap MMIO instead of customised sifive_assign_bit() - Use GPIOLIB_GENERIC and bgpio_init() to set up the accessors - Use hierarchical irqdomain [0] https://lore.kernel.org/linux-riscv/20181010123519.RVexDppaPFpIWl7QU_hpP8tc5qqWPJgeuLYn0FaGbeQ@z/ Yash Shah (5): genirq: introduce irq_domain_translate_onecell irqchip: sifive: Support hierarchy irq domain gpio: sifive: Add DT documentation for SiFive GPIO gpio: sifive: Add GPIO driver for SiFive SoCs riscv: dts: Add DT support for SiFive FU540 GPIO driver .../devicetree/bindings/gpio/gpio-sifive.yaml | 69 ++++++ arch/riscv/boot/dts/sifive/fu540-c000.dtsi | 14 +- .../riscv/boot/dts/sifive/hifive-unleashed-a00.dts | 4 + drivers/gpio/Kconfig | 9 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-sifive.c | 256 +++++++++++++++++++++ drivers/irqchip/Kconfig | 1 + drivers/irqchip/irq-sifive-plic.c | 30 ++- include/linux/irqdomain.h | 5 + kernel/irq/irqdomain.c | 20 ++ 10 files changed, 404 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-sifive.yaml create mode 100644 drivers/gpio/gpio-sifive.c -- 2.7.4
