Merge tag 'scpi-for-v4.6/updates' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into next/drivers
SCPI updates and fixes for v4.6
1. Minor fix to restore functionality in big-endian mode
2. Fix race by decreasing Tx timeout to 20ms
3. Adds support for 64-bit sensor values and energy meter
* tag 'scpi-for-v4.6/updates' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:
hwmon: (scpi) add energy meter support
firmware: arm_scpi: add support for 64-bit sensor values
firmware: arm_scpi: decrease Tx timeout to 20ms
firmware: arm_scpi: fix send_message and sensor_get_value for big-endian
