Merge tag 'scmi-updates-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into next/drivers
SCMI updates for v4.20
1. Addition of interface to fetch estimated power from the firmware
corresponding to each OPP of a device
2. Cleanup using strlcpy to ensure NULL-terminated strings for name
strings instead of relying on the firmware to do the same
* tag 'scmi-updates-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:
firmware: arm_scmi: add a getter for power of performance states
firmware: arm_scmi: use strlcpy to ensure NULL-terminated strings
