rtc: remove useless DRV_VERSION

2016-05-20T10:33:51+00:00

Many drivers are defining a DRV_VERSION. This is often only used for
MODULE_VERSION and sometimes to print an info message at probe time. This
is kind of pointless as they are all versionned with the kernel anyway.
Also the core will print a message when a new rtc is found.

rtc: isl1208: Pass the IRQF_ONESHOT flag

2015-11-08T13:12:30+00:00

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.

So pass the IRQF_ONESHOT flag in this case.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/irqf_oneshot.cocci

rtc: isl1208: Replace deprecated rtc_tm_to_time()

2015-06-24T23:13:42+00:00

isl1208_i2c_set_alarm() uses deprecated rtc_tm_to_time(),
which will overflow in year 2106 on 32-bit machines.

This patch solves this by:
 - Replacing rtc_tm_to_time() with rtc_tm_sub()

i2c_smbus_read_byte_data() returns negative errno on failure.  Return the
value obtained from it directly.

drivers/rtc/rtc-isl1208.c: call rtc_update_irq() from the alarm irq handler

2013-02-05T09:38:49+00:00

Previously the alarm event was not propagated into the RTC subsystem.
By adding a call to rtc_update_irq, this fixes a timeout problem with
the hwclock utility.

drivers/rtc/rtc-isl1208.c: convert struct i2c_msg initialization to C99 format

2012-10-05T18:05:06+00:00

Convert the struct i2c_msg initialization to C99 format.  This makes
maintaining and editing the code simpler.  Also helps once other fields
like transferred are added in future.

drivers/rtc/rtc-isl1208.c: add support for the ISL1218

2012-10-05T18:05:01+00:00

The ISL1218 chip is identical to the ISL1208, except that it has 6
additional user-storage registers.  This patch does not enable access to
those additional registers, but only adds the chip name to the list.
