| * | ARM: cpuidle: Register per cpuidle device | Daniel Lezcano | 2015-03-24 | 1 | -2/+43 |
| | | | | | | | | | | | | | | | | | | If the cpuidle init cpu operation returns -ENXIO, therefore reporting HW failure or misconfiguration, the CPUidle driver skips the respective cpuidle device initialization because the associated platform back-end HW is not operational. That prevents the system to crash and allows to handle the error gracefully. For example, on Qcom's platform, each core has a SPM. The device associated with this SPM is initialized before the cpuidle framework. If there is an error in the initialization (eg. error in the DT), the system continues to boot but in degraded mode as some SPM may not be correctly initialized.

| * | ARM: cpuidle: Enable the ARM64 driver for both ARM32/ARM64 | Daniel Lezcano | 2015-03-24 | 1 | -0/+122 |
| ARM32 and ARM64 have the same DT definitions and the same approaches. The generic ARM cpuidle driver can be put in common for those two architectures.
