From 2e8741599cf128ea27674d9ae93b46e847f820b4 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 14 Jan 2016 17:58:02 +0000 Subject: firmware: arm_scpi: add support for 64-bit sensor values SCPI specification version 1.1 extended the sensor from 32-bit to 64-bit values in order to accommodate new sensor class with 64-bit requirements Since the SCPI driver sets the higher 32-bit for older protocol version to zeros, there's no need to explicitly check the SCPI protocol version and the backward compatibility is maintainted.
