Add support for describing the PM8921/PM8058 RTC in device tree. Additionally: - drop support for describing the RTC using platform data, as there are no current in tree users who do so. - make allow_set_time a device-specific flag, instead of mucking with the rtc_ops Signed-off-by:Josh Cartwright <joshc@codeaurora.org> Reviewed-by:

Now that the parent mfd driver has been made to work again, and has been reworked to create a regmap instance intended for its children to use, rework the pm8xxx driver to use the regmap API for its register accesses. Signed-off-by:

This patchset is based on Stephen Boyd's PM8921 modernization/cleanups (http://lkml.kernel.org/g/1393441166-32692-1-git-send-email-sboyd@codeaurora.org), and allows for this RTC driver to be usable again. This patch (of 6): Before performing additional cleanups to this driver, do the easy cleanups first. Signed-off-by:

CONFIG_PM will be set also if only CONFIG_PM_RUNTIME is set which causes the compiler to emit following warning: drivers/rtc/rtc-cmos.c:845:12: warning: =E2=80=98cmos_resume=E2=80=99 defined but not used [-Wunused-function] Fix this by using CONFIG_PM_SLEEP instead of CONFIG_PM and removing it from the driver pm ops as this has been taken care by SIMPLE_DEV_PM_OPS() already.

It's possible to have RTC irq shared with other device (e.g. t4240qds board shares ds3232irq with phy one). Handle this in driver. Signed-off-by:

The Allwinner A10 compatibles were following a slightly different compatible patterns than the rest of the SoCs for historical reasons. Change the compatibles to match the other pattern in the RTC driver for consistency. Signed-off-by:

Remove unnecessary locks when reading the time and make the read operation until the values of day matched between reading the seconds, it will make the mc13xxx_rtc_read_time() procedure more readable. Additionally, patch introduced a "seconds in a day" definition. Signed-off-by:

Datasheet says: "When the VSRTC voltage drops to the range of 0.9 - 0.8V, the RTCPORB reset signal is generated and the contents of the RTC will be reset. <skip>. To inform the processor that the contents of the RTC are no longer valid due to the reset, a timer reset interrupt function is implemented with the RTCRSTI bit." This patch makes the RTC valid by default until RTCRST interrupt occurs. Signed-off-by:

Interrupts can appear after request_irq and interrupt handlers can use the RTC device, but currently we register RTC after IRQs. This patch changes this order and simplify error path a bit. Signed-off-by:

Since we no longer allow building without hotplug, the mc13xxx_rtc_remove() function is always present and we should not use __exit_p() to refer to it. Signed-off-by:

Use devm_ioremap_resource() in order to make the code simpler, and move 'struct resource *mem' from 'struct jz4740_rtc' to jz4740_rtc_probe() because the 'mem' variable is used only in jz4740_rtc_probe().
