The user can enable or disable as well as can configure the runtime features. The support is added for the over temperature and external watchdog. The user can configure the over temperature limit and external watchdog timer interval at runtime by using PM_IOCTL calls. Also, added support for sysfs interface for runtime feature configuration for the over temperature and external watchdog features. Added zynqmp_devinfo structure to handle multiple driver instances when accessed by multiple devices. Changes in v5: - Resolved merge conflict - Update kernel version for sysfs documentation Changes in v4: - Update documentation for sysfs entries in #2 patch - Add separate entries for sysfs files Changes in v3: - Added zynqmp_devinfo structure to store device instances - Modified feature_conf_id from atomic variable to u32 - Update commit message - Resolved merge conflict Changes in v2: - Remove default footer from email - Update commit message - Resolved merged conflict Ronak Jain (3): firmware: xilinx: Add support for runtime features firmware: zynqmp: Add documentation for runtime feature config firmware: xilinx: Add sysfs support for feature config .../ABI/stable/sysfs-driver-firmware-zynqmp | 141 ++++++++++++++++++ drivers/firmware/xilinx/zynqmp.c | 120 +++++++++++++++ include/linux/firmware/xlnx-zynqmp.h | 25 ++++ 3 files changed, 286 insertions(+) -- 2.32.0.93.g670b81a
