* soc: qcom: Implement early domain handoff driverVivek Kumar2018-11-23
| | | | | | | | | | | | | Early domain in LK runs in parallel with kernel with some memory and cpu core(s) reserved for it. LK updates the status of early services on a shared memory location. In Kernel, this driver provides new APIs to check any early service's status and to communicate with them. It hot adds the reserved cpu(s) and frees lk text once all early services end.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using 1 millisecond Rx polling sleep makes the cpu wake up too often, results in more power consumption. Using 3 milliseconds is helping on MSM8940 in terms of both power and performance. Give provision to change the polling time via device tree entry and use 3 milliseconds for MSM8940. And also give provision to modify the rx polling timeout via debugfs entry for testing purposes.
