From: Richard Gong <richard.gong@xxxxxxxxx> This is the 4th submission of Intel Stratix10 remote system update (RSU) driver. Intel Stratix10 remote system update driver patches have been reviewed by Alan Tull and other colleagues at Intel. The Intel Stratix10 Remote System Update driver exposes interfaces access through the Intel Stratix10 Service Layer to user space via sysfs interface. The RSU interfaces report and control some of the optional RSU features on Intel Stratix 10 SoC. The RSU feature provides a way for customers to update the boot configuration of a Intel Stratix 10 SoC device with significantly reduced risk of corrupting the bitstream storage and bricking the system. v4: removed devm_device_add_groups() & devm_device_remove_groups(), then utilized groups at struct device_driver replaced /sys/devices/platform/stratix10-rsu.0/ with /sys/devices/.../ stratix10-rsu.0/driver/ removed spaces v3: changed kernel version from 5.2 to 5.3 in RSU sysfs interface document v2: removed compatible = "intel,stratix10-rsu" added intel stratix10 RSU device changed to support RSU in handling watchdog timeout s/attr_group/ATTRIBUTE_GROUPS, use devm_device_add_groups() and devm_device_remove_groups() added check the return value from rsu_send_msg() removed RSU binding text file other corrections/change Richard Gong (4): firmware: stratix10-svc: extend svc to support RSU notify and WD features firmware: add Intel Stratix10 remote system update driver firmware: rsu: document sysfs interface MAINTAINERS: add maintainer for Intel Stratix10 FW drivers .../testing/sysfs-devices-platform-stratix10-rsu | 100 +++++ MAINTAINERS | 11 + drivers/firmware/Kconfig | 18 + drivers/firmware/Makefile | 1 + drivers/firmware/stratix10-rsu.c | 403 +++++++++++++++++++++ drivers/firmware/stratix10-svc.c | 74 +++- include/linux/firmware/intel/stratix10-smc.h | 48 ++- .../linux/firmware/intel/stratix10-svc-client.h | 12 +- 8 files changed, 657 insertions(+), 10 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-devices-platform-stratix10-rsu create mode 100644 drivers/firmware/stratix10-rsu.c -- 2.7.4
