The gpio patches are mostly based on Wesley's patch= . The patchset also adds hierarchy irq domain support as it is required by th= is gpio driver. It also includes the irqdomain patch to introduce irq_domain_translate_onecell() and irq-nvic driver patch to use this newly introduced function. This patchset is based on Linux 5.4-rc6 and tested on HiFive Unleashed boar= d Changes: v3 vs v2: - Include patch for irq-nvic driver to use irq_domain_translate_onecell - Remove unnecessary inclusion of header files - Use a single prefix for all symbols in this driver - Rename the "enabled" field of struct sifive_gpio to "irq_state" - Remove unused variables and locking from probe() - Other minor 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_hp= P8tc5qqWPJgeuLYn0FaGbeQ@z/ Yash Shah (6): genirq: introduce irq_domain_translate_onecell irqchip: nvic: Use irq_domain_translate_onecell instead of custom func 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 | 252 +++++++++++++++++= ++++ drivers/irqchip/Kconfig | 1 + drivers/irqchip/irq-nvic.c | 15 +- drivers/irqchip/irq-sifive-plic.c | 30 ++- include/linux/irqdomain.h | 5 + kernel/irq/irqdomain.c | 17 ++ 11 files changed, 399 insertions(+), 18 deletions(-) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-sifive.yaml create mode 100644 drivers/gpio/gpio-sifive.c --=20 2.7.4
