2015-12-15clocksource/drivers/h8300_timer8: Fix compilation error with dev_warnDaniel Lezcano1-1/+1

2015-12-15clocksource/drivers/dw_apb_timer_of: Implement ARM delay timerJisheng Zhang1-0/+16
Implement an ARM delay timer to be used for udelay(). This allows us to skip the delay loop calibration at boot on Marvell BG2, BG2Q, BG2CD platforms. And after this patch, udelay() will be unaffected by CPU frequency changes. Note: Although in case there are several possible delay timers, we may not select the "best" delay timer. Take one Marvell Berlin platform for example: we have arch timer and dw-apb timer. The arch timer freq is 25MHZ while the dw-apb timer freq is 100MHZ, current selection would choose the dw-apb timer. But the dw apb timer is on the APB bus while arch timer sits in CPU, the cost of accessing the apb timer is higher than the arch timer. We could introduce "rating" concept to delay timer, but this approach "brings a lot of complexity and workarounds in the code for a small benefit" as pointed out by Daniel. Later, Arnd pointed out "However, we could argue that this actually doesn't matter at all, because the entire point of the ndelay()/ udelay()/mdelay() functions is to waste CPU cycles doing not much at all, so we can just as well waste them reading the timer register than spinning on the CPU reading the arch timer more often.", so we just simply register the dw apb base delay timer.

2015-12-15clocksource/drivers/Kconfig: Add missing GENERIC_CLOCKEVENTS dependencyDaniel Lezcano1-0/+11
In order to compile on all arch without error with 'allyesconfig' make sure the platform selected the GENERIC_CLOCKEVENTS. Without this patch the new added drivers will prevent the kernel to compile on PARISC. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>

Let the platform's Kconfig to select the clock instead of having a reverse dependency from the driver to the platform options. Add the COMPILE_TEST option for the compilation test coverage. This change is debatable as the option itself in the Kconfig allows to select the driver for the platform or not. This change will make the prcmu timer always selected.
