v8: - use gpio 0 and 1, align dtb with kernel gpio-restart, gpio-poweroff, change define names, trigger on upper front. (Peter Maydell). v7: - same as v6, but resplit patches: patch 2 no function changes and refactor gpio setup for virt platfrom and patch 3 adds secure gpio. v6: - 64k align gpio memory region (Andrew Jones) - adjusted memory region to map this address in the corresponding atf patch v5: - removed vms flag, added fdt (Andrew Jones) - added patch3 to combine secure and non secure pl061. It has to be more easy to review if this changes are in the separate patch. v4: rework patches accodring to Peter Maydells comments: - split patches on gpio-pwr driver and arm-virt integration. - start secure gpio only from virt-6.0. - rework qemu interface for gpio-pwr to use 2 named gpio. - put secure gpio to secure name space. v3: added missed include qemu/log.h for qemu_log(.. v2: replace printf with qemu_log (Philippe Mathieu-Daudé)
This patch works together with ATF patch: https://github.com/muvarov/arm-trusted-firmware/commit/886965bddb0624bdf8510...
