This series adds support to skip powering up of trace unit on systems with an errata which stops CPU watchdog counter when power up bit is set (TRCPDCR.PU = 1). Setting this bit is not required on Qualcomm Technologies Inc. chipsets where this errata exists since the ETMs are in the same power domain as their respective CPU cores. Changes since v2: * Fix checkpatch warning for 80 characters. Changes since v1: * Use qcom,skip-power-up for naming as suggested by Mathieu. * Have check for DT property in initialization as per Mathieu. * Reword description for property as per Mathieu. * Split up dt-binding patch as checkpatch complains.
