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 Signed-off-by: Olof Johansson <olof@lixom.net>
