Message

Jolly Shah April 24, 2020, 8:57 p.m. UTC

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.

It depends on below patchset which fixes firmware driver Kconfig dependency.
