rtc: goldfish: remove dependency to OF

2021-04-16T20:25:20+00:00

We want to use the goldfish RTC on a machine without OF.
As there is no real dependency on it, remove the OF dependency from the
goldfish entry in Kconfig

rtc: bd70528: Support RTC on ROHM BD71815

2021-04-14T09:21:34+00:00

BD71815 contains similar RTC block as BD71828. Only the address offsets
seem different. Support also BD71815 RTC using rtc-bd70528.

rtc: imxdi: Convert to a DT-only driver

i.MX has been converted to a DT-only platform, so make the driver
depend on OF, remove the CONFIG_OF ifdefery and remove of_match_ptr().

rtc: New driver for RTC in Netronix embedded controller

2021-03-10T11:06:33+00:00

With this driver, mainline Linux can keep its time and date in sync with
the vendor kernel.

Advanced functionality like alarm and automatic power-on is not yet
supported.

rtc: armada38x: depend on OF

2021-02-05T23:58:24+00:00

The driver will compile with warning without OF because armada38x_data and
armada8k_data will be defined but not used. It would be possible to move
then in the #ifdef CONFIG_OF section but then their members will be defined
but not used. Instead of moving most of the driver in the #ifdef, simply
depend on OF.

rtc: zynqmp: depend on HAS_IOMEM

2021-02-02T23:55:01+00:00

The Xilinx zynqmp RTC driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.

This causes the driver not to be enable under make ARCH=um allyesconfig,
even though it won't build.

By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

rtc: mrst: Remove driver for deprecated platform

2021-01-25T18:05:31+00:00

Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.

There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit
05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.

Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.
