drivers: add irq interrupt framework support This patch add support for IRQ interrupt, FIQ not included. It will be enabled when you select CONFIG_GICV2 or CONFIG_GICV3. The framework support gic interrupt and gpio interrupt, relative APIs are provided in: ./include/irq-platform.h If you'd like to add a new platform support into interrupt framework, please follow the steps: 1. add relative definitions in the file like other platforms: ./include/irq-platform.h 2. add GICD, GICC and GICR(for GICV3) base address definitions in the rkxxx-common.h, they are needed in: arch/arm/cpu/armv8/start.S; 3. enable CONFIG_GICV2 or CONFIG_GICV3. Notice: 1. the framework is initialize in function 'interrupt_init()' of _sequence_r[]. So you should not request irqs too early. 2. IRQ stack size is configured by CONFIG_IRQ_STACK_SIZE, the default value is 8KB when CONFIG_IRQ_STACK_SIZE is absent.

drivers: irq: add irq to gpio v2 transfer support Some platform with new GPIO IP implements the low/high registers with write mask. This configure handles it. Signed-off-by: Joseph Chen <chenjh@rock-chips.com> Change-Id: I855357d29e7fba072b867c06a31a049462ebf6ff 2020-03-25 13:11:29 +00:00
