My earlier misgivings that it might be a problem for the suspend/resume implementation later on did not hold true: I tested my prelinear suspend code and in case the code really needs to access some registers form assembler, it is possible to map temporarly the relevant region again. I refrained from adding POWER_RESET_SYSCON as a hard dependency for Vybrid (SOC_VF610): In its dual-core configuration, one might want have the Cortex-M4 in charge of the system reset... Hence the user should be able to build a kernel without the system reset (beside the option to create a board specific device tree with disabled SRC node). Shawn, the defconfig change is based on the latest (almost-merged?) defconfig patch. Changes since v2: - Drop priority property for syscon-reboot - Alter default priority of syscon-reboot, set it to 192 Changes since v1: - Total rework using syscon/syscon-reboot capabilities - Enhance syscon-reboot with priority capabilities Stefan Agner (3): power: reset: adjust priority of simple syscon reboot driver ARM: dts: vf610: add system reset controller and syscon-reboot ARM: imx_v6_v7_defconfig: add POWER_RESET_SYSCON arch/arm/boot/dts/vf500.dtsi | 4 ++++ arch/arm/boot/dts/vfxxx.dtsi | 12 ++++++++++++ arch/arm/configs/imx_v6_v7_defconfig | 8 ++++---- drivers/power/reset/syscon-reboot.c | 2 +- 4 files changed, 21 insertions(+), 5 deletions(-) -- 2.1.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
