We should get 'driver_data' from 'struct device' directly. Going via
platform_device is an unneeded step back and forth.

Use rtc_add_group to add the sysfs group in a race free manner.

rtc: ds1685: use generic nvmem2018-09-28T12:21:01ZAlexandre Bellonialexandre.belloni@bootlin.com2018-09-19T17:52:10Zurn:sha1:482419e120da6da187be996c6871ed1e8bf02c51
Instead of adding a binary sysfs attribute from the driver, use the core to
register an nvmem device.

/proc is not the correct ABI to display debugging info. Remove
RTC_DS1685_PROC_REGS as the driver hasn't seen any real development since
it was included.

rtc: ds1685: remove sysfs access to control registers2018-06-20T10:38:14ZAlexandre Bellonialexandre.belloni@bootlin.com2018-06-18T08:52:02Zurn:sha1:a41efe03e6110d7d85db272290aeed7e1ce9b63b
Access to the control registers is mostly not needed and can cause runtime
issues (like missed interrupts). Remove this debugging interface.

The driver exposes an undocumented ABI to access the date and time
registers. It is not actually used by any userspace tools. Remove it.

Useful range is 2000-2099 because leap year fails on centuries.

The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler.
Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before requesting the IRQ.

rtc: stop validating rtc_time in .read_time2018-03-02T09:09:58ZAlexandre Bellonialexandre.belloni@bootlin.com2018-02-19T15:23:56Zurn:sha1:22652ba72453d35c8a637d5c0f06b3dc29ff9eb0
The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it just before returning from the callback.
