| |
This patchset contains the initial GPIO support for the Broadcom Cygnus SoC. Cygnus has 3 GPIO controllers: 1) the ASIU GPIO; 2) the chipCommonG GPIO; and 3) the ALWAYS-ON GPIO. All 3 types of GPIO controllers are supported by the same Cygnus GPIO driver
Changes from v5: - Get rid of DT property "linux,gpio-base". Use dynamic allocation for GPIO base number
Changes from v4: - Use DT property "linux,gpio-base" to define GPIO base number - factorize common code to improve code readability and reduce code size - remove "bcm_" prefix on function and struct names - improve debugging prints - default GPIO_BCM_CYGNUS to y in Kconfig (it still depends on ARCH_BCM_CYGNUS). This way we do not need to select it from the arch/arm/mach-bcm/Kconfig - Get rid of redundant MAINTAINER entry for this driver. It will be maintained by Broadcom iProc/Cygnus maintainers - Update device tree document based on driver changes
Changes from v3: - Fix dt property tpyo - Fix incorrect GPIO compatible ID in device tree binding document example
Changes from v2: - Consolidate different compatible IDs into "brcm,cygnus-gpio" - Get rid of redundant "no-interrupt" property
Changes from v1: - Get rid of inline qualifier - Get rid of redundant check in the ISR - Other minor fixes to imrove code readability
