rtc: m48t59: Use platform_data struct for year offset value

2024-11-18T13:31:57+00:00

Instead of hard-coded values and ifdefs, store the year offset in the
platform_data struct.

rtc: ds1685: drop no_irq

2022-03-23T18:58:38+00:00

No platforms are currently setting no_irq. Anyway, letting platform_get_irq
fail is fine as this means that there is no IRQ. In that case, clear
RTC_FEATURE_ALARM so the core knows there are no alarms.

rtc: remove sirfsoc driver

2021-01-23T13:57:21+00:00

The CSR SiRF prima2/atlas platforms are getting removed, so this driver
is no longer needed.

rtc: ds1685: add indirect access method and remove plat_read/plat_write

2019-10-16T08:39:00+00:00

SGI Octane (IP30) doesn't have RTC register directly mapped into CPU
address space, but accesses RTC registers with an address and data
register.  This is now supported by additional access functions, which
are selected by a new field in platform data. Removed plat_read/plat_write
since there is no user and their usage could introduce lifetime issue,
when functions are placed in different modules.

rts: ds1685: remove not needed fields from private struct

2019-10-14T15:49:21+00:00

A few of the fields in struct ds1685_priv aren't needed at all,
so we can remove it.

rtc: ds1685: use threaded interrupt

2019-04-16T16:03:48+00:00

Handling of extended interrupts (kickstart, wake-up, ram-clear) was
moved off to a work queue, but the interrupts aren't acknowledged
in the interrupt handler. This leads to a deadlock, if driver
is used with interrupts. To fix this we use a threaded interrupt, get rid
of the work queue and do locking with just the rtc mutex lock.
