Following files contains code that is common to all intel mid soc's. So renamed them as below. mrst/mrst.c -> intel-mid/intel-mid.c mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c pci/mrst.c -> pci/intel_mid_pci.c Also, renamed the corresponding header files and made changes to the driver files that included these header files. To ensure that there are no functional changes, I have compared the objdump of renamed files before and after rename and found that the only difference is file name change.

由 John Stultz 提交于
In some recent testing, I noticed the CLOCK_REALTIME_ALARM clockid wasn't functioning on my vexpress qemu environment. Looking into it I noticed the pl031 rtc driver doesn't set the wakeup flag on the device until after registering the device with the RTC subsystem. This causes the alarmtimer subsystem to not see the pl031 driver as a valid backing device, and that resuls in alarm clockids getting ENOTSUPP errors. Thus be sure to set the wakeup flag on the device prior to registering the rtcdev so the pl031 rtc driver can be used as the backing alarmtimer device.

Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed. In rtc-ds1511.c the size field of the local structure is not useful any more, and is deleted.

It's always a bad idea to poll on HW bits without a timeout. The i.MX28 RTC can be easily brought into a state in which the RTC is not running (until after a power-on-reset) and thus the status bits which are polled in the driver won't ever change. This patch prevents the kernel from getting stuck in this case.

由 Zoran Markovic 提交于
Current implementation of RTC interface allows for system suspend to occur in the following cases: (a) if a timer is set in the past and rtc_timer_do_work() is scheduled to handle it, and (b) if rtc_timer_do_work() is called to handle expired timers whose handlers implement a preemption point. A pending suspend request may be honoured in the above cases causing timer handling to be delayed until after the next resume. This is undesirable since timer handlers may have time-critical code to execute. This patch makes sure that the system stays awake until all expired timers are handled. Note that all calls to pm_stay_awake() are eventually paired with the single pm_relax() call in rtc_timer_do_work(), which is launched using schedule_work().
