* clocksource: timer: t186: add timer suspend hooksumitg2018-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding syscore suspend hook to disable timer for boot core and function to enable irq on boot core during resume. Also, clearing interrupts after disabling timer on all cores. Change is done to fix scenario where SC7 entry fails due to unserviced interrupt if the timer interrupt is generated after disabling local irq delivery on boot core and before doing SC7 entry check in ATF as an interrupt is pending to be serviced. During suspend, disabling timer on boot core will stop any new timer interrupt. And clearing timer interrupts after disabling timer on all cores will make sure no interrupt is pending before checking SC7 entry.

* clocksource: update tegra18 clocksource to use OSCAlex Van Brunt2015-11-19
| | | | | | | | | | | | | | | | | | | | | | | The TSC is used to clock the bus for the TKE. Therefore it cannot be halted while debugging because any access will hang. However, the TKE needs to stop the timers durring debug. The solution is to keep the TSC running but use OSC to driver the timers and then to halt the timer in debug. This patch switches the timers to use OSC instead of TSC as the time source. The clk "osc" is not available at the time that the timer registers itself. This is because tegra186-clocks is registered later. Therefore, this driver must rely on the frequency in the device-tree for OSC.
