Subject[PATCH v4 00/25] firmware: xilinx: Add xilinx specific sysfs interface
Date
This patch series adds xilinx specific sysfs interface for below
purposes:
- Register access
- Set shutdown scope
- Set boot health status bit

Also this patch series removes eemi ops and adds API
corresponding to each eemi ops.

firmware: xilinx: Remove eemi ops for clock_enable
firmware: xilinx: Remove eemi ops for clock_disable
firmware: xilinx: Remove eemi ops for clock_getstate
firmware: xilinx: Remove eemi ops for clock_setdivider
firmware: xilinx: Remove eemi ops for clock_getdivider
firmware: xilinx: Remove eemi ops for clock set/get rate
firmware: xilinx: Remove eemi ops for clock set/get parent
firmware: xilinx: Use APIs instead of IOCTLs
firmware: xilinx: Remove eemi ops for reset_assert
firmware: xilinx: Remove eemi ops for reset_get_status
firmware: xilinx: Remove eemi ops for init_finalize
firmware: xilinx: Remove eemi ops for set_suspend_mode
firmware: xilinx: Remove eemi ops for request_node
firmware: xilinx: Remove eemi ops for release_node
firmware: xilinx: Remove eemi ops for set_requirement
firmware: xilinx: Remove eemi ops for aes engine
firmware: xilinx: Remove eemi ops for fpga related APIs
firmware: xilinx: Add APIs to read/write GGS/PGGS registers
firmware: xilinx: Add sysfs interface
firmware: xilinx: Add system shutdown API interface
firmware: xilinx: Add sysfs to set shutdown scope
firmware: xilinx: Add sysfs and API to set boot health status
