2018-01-08clocksource/drivers/timer-of: Don't request the resource by nameDaniel Lezcano1-4/+4
When the driver does not specify a name for the resource, don't use of_io_request_and_map() but of_iomap(). That prevents resource name allocation conflicts on some platforms which have the same name as the node.

2018-01-08clocksource/drivers/timer-of: Store the device node pointer in 'struct timer_of'Daniel Lezcano2-0/+4
Under certain circumstances, some specific operations must be done with the device node pointer, which forces the timer code to propagate the pointer to the functions which need it. In order to consolidate the function signatures in the different drivers by using the timer-of structure, let's store it in the timer-of structure as a handy pointer when it is needed.

2018-01-08clocksource/drivers/spreadtrum: Add timer driver for the Spreadtrum SC9860 platformBaolin Wang3-0/+167
The Spreadtrum SC9860 platform will use the architected timers as local clock events, but we also need a broadcast timer device to wake up the CPUs when the CPUs are in sleep mode. The Spreadtrum timer can support 32-bit or 64-bit counters, as well as supporting period mode or one-shot mode.
