still don't know anything about virtio but under Linux, an RTC is
always UTC (or localtime when dual booting but let's not care) and never
accounts for leap seconds. Having an RTC and RTC driver behaving
differently would be super inconvenient. Why don't you leave this to
userspace?

The CCF will disable any clocks that are not used on boot so the clock
will be either used and configured or not used and disabled.

Alarm support requires unconditionally disabling clock out because it is
using the int1 pin.

This is mostly about the RTC driver but the bindings doc is in mfd. How
do you prefer that to be merged? there is no build dependency so I can
take 1 and 4 and you could take 2 and 3. Or one of us can take all 4
patches.

Yes, this driver IP is also available on Ocelot (this is SOC_VCOREIII)
so this is also available over SPI.

ny platforms with the dtb built into the firmware? I
feel like this is a mythical creature used to scare people into keeping
the DTB ABI stable. Aren't all the distribution already able to cope
with keeping DTB and kernel in sync?

and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK
PLL.
Currently, the HCLK driver simply updates the registers but this has no
real effect and all the clock rate calculation end up being wrong. This is
especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

It doesn't make sense to set the RTC to a default value at probe time. Let
the core handle invalid date and time.
Also, this is basically dead code since commit 22652ba72453 ("rtc: stop
validating rtc_time in .read_time")

Hi,
This series removes some make W=1 warning, especially when CONFIG_OF is
not defined.
Alexandre Belloni (21):
rtc: class: remove bogus documentation
rtc: armada38x: depend on OF

The PORF bit is cleared on interrupts which prevents the driver to know
when the time and date are invalid. Stop clearing PORF in the interrupt
handler.
