2019-04-04rtc: remove unnecessary Kconfig dependenciesAlexandre Belloni1-2/+0
Remove the unused "depends on I2C" as the config options are already guarded by if I2C. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: add RTC_VL_READ/RTC_VL_CLR supportAlexandre Belloni1-0/+35
Allow reading the oscillator status bit. Also allow clearing it even if that makes little sense and can't be done in a race free way. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: add offset correction supportAlexandre Belloni1-1/+57
The PCF850363 has an offset correction with two modes: With mode 0, the correction is triggered once every two hours and then correction pulses are applied once per minute until the programmed correction values have been implemented. This gives a step of 4.34 ppm. With mode 1, the correction is triggered once every four minutes and then correction pulses are applied once per second up to a maximum of 60 pulses. When correction values greater than 60 pulses are used, additional correction pulses are made in the 59 th second. This gives a step of 4.069 ppm. Use the correction closest to the requested value.

2019-04-04rtc: pcf85063: add nvram supportAlexandre Belloni1-0/+24
The pcf85063 has one byte of nvram. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: add Micro Crystal RV8263 supportAlexandre Belloni1-4/+28
The Micro Crystal RV8263 has the same IC as the pcf85063 but has an on board crystal. This means that the CAP_SEL bit has to be cleared so the correct capacitance is selected for the crystal. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: add alarm supportAlexandre Belloni1-0/+121
Add support for the alarms. The match on the weekday is not used as it it not necessarily properly set. The tested RTC shows a behaviour where setting an alarm on the second right after an alarm that fired is not working, probably because of the circuit that ensures an alarm only fires once. This is why uie_unsupported is set. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: differentiate pcf85063a and pcf85063tpAlexandre Belloni1-6/+27
As stated in a comment pcf85063a and pcf85063tp don't have the same number of registers. Especially, pcf85063tp doesn't have alarm support. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: switch to regmapAlexandre Belloni2-93/+62
Switch to regmap to simplify register accesses and remove the need for pcf85063_stop_clock/pcf85063_start_clock. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: set rangeAlexandre Belloni1-3/+2
This is a standard BCD RTC that will fail in 2100. Signed-off-by: Alexandre Belloni <[email protected]>

This allows further improvement of the driver. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: pcf85063: remove bogus i2c functionality checkAlexandre Belloni1-3/+0
Only smbus reads and write are done in the driver, plain i2c functionality is not required. Signed-off-by: Alexandre Belloni <[email protected]>

2019-04-04rtc: pcf85063: switch to probe_newAlexandre Belloni1-10/+2
struct i2c_device_id argument of probe() is not used, so use probe_new() instead. Signed-off-by: Alexandre Belloni <[email protected]>
2019-04-04rtc: snvs: use devm_platform_ioremap_resource() to simplify codeAnson Huang1-3/+1
Use the new helper devm_platform_ioremap_resource() which wraps the platform_get_resource() and devm_ioremap_resource() together, to simplify the code. Signed-off-by: Anson Huang <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]>

2019-04-04rtc: snvs: use dev_pm_set_wake_irq() to simplify codeAnson Huang1-21/+4
With calling dev_pm_set_wake_irq() to set SNVS RTC as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the suspend/resume callback which are ONLY for enabling/disabling irq wake can be removed, it simplifies the code.

2019-04-04rtc: mt6397: Don't call irq_dispose_mapping.Pi-Hsun Shih1-6/+3
The IRQ mapping was changed to not being created in the rtc-mt6397 driver, so the irq_dispose_mapping is no longer needed. Also the dev_id passed to free_irq should be the same as the last argument passed to request_threaded_irq. This prevents a "Trying to free already-free IRQ 274" warning when unbinding the driver.

2019-04-04rtc: sh: fix possible race conditionAlexandre Belloni1-7/+9
The IRQ is requested before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference.
