rtc: simplify getting .drvdata

2018-05-03T20:08:00+00:00

We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Acked-by: Michal Simek (for zynqmp) Signed-off-by: Alexandre Belloni

rtc: mxc: avoid disabling interrupts on device close

2017-08-24T14:23:16+00:00

Currently, the IRQs are disabled when the rtc character device is closed. This means that the device needs to stay open to get alarms while the usual use case will open the device, set the alarm and close the device as is done in rtcwake. Keep the alarm functional on character device release so the platform can actually wakeup. Reviewed-by: Fabio Estevam Signed-off-by: Alexandre Belloni

rtc: mxc: remove unused variable

2017-06-24T05:58:09+00:00

This variable was never used. With GCC 6.2, we get the following warning: drivers/rtc/rtc-mxc.c:44:18: warning: ‘PIE_BIT_DEF’ defined but not used [-Wunused-const-variable=] static const u32 PIE_BIT_DEF[MAX_PIE_NUM][2] = { Signed-off-by: Diaz de Grenu, Jose Signed-off-by: Alexandre Belloni

rtc: constify rtc_class_ops structures

2017-01-11T16:23:06+00:00

Declare rtc_class_ops structures as const as they are only passed as an argument to the function devm_rtc_device_register. This argument is of type const struct rtc_class_ops *, so rtc_class_ops structures having this property can be declared const. Done using Coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct rtc_class_ops i@p = {...}; @ok1@ identifier r1.i; position p; @@ devm_rtc_device_register(...,&i@p,...) @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct rtc_class_ops i; Signed-off-by: Bhumika Goyal Signed-off-by: Alexandre Belloni

rtc: mxc: remove UIE signaling

The RTC core handles it since 6610e08 (RTC: Rework RTC code to use timerqueue for events). Signed-off-by: Wolfram Sang Signed-off-by: Alexandre Belloni

rtc: mxc: add support of device tree

2015-08-05T12:03:56+00:00

Add device tree support for the mxc rtc driver. Acked-by: Alexandre Belloni Signed-off-by: Philippe Reynes Signed-off-by: Shawn Guo

rtc: mxc: use a second rtc clock

2015-08-05T12:03:46+00:00

The mxc RTC needs two clocks, one for the input reference, and one for the IP. But this driver was only using one clock (for the reference). This patch add the second clock (for the IP). Acked-by: Alexandre Belloni Signed-off-by: Philippe Reynes Signed-off-by: Shawn Guo

rtc: mxc: Constify platform_device_id

2015-06-19T18:03:20+00:00

The platform_device_id is not modified by the driver and core uses it as const. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Alexandre Belloni

drivers/rtc/mxc: Update driver to address y2038/y2106 issues

2015-04-03T06:18:29+00:00

This driver has a number of y2038/y2106 issues. This patch resolves them by: - Replacing rtc_time_to_tm() with rtc_time64_to_tm() - Replacing rtc_tm_to_time() with rtc_tm_to_time64() - Changing mxc_rtc_set_mmss() to use rtc_class_ops's set_mmss64() After this patch, the driver should not have any remaining y2038/y2106 issues.
