2017-09-05dt-bindings: Remove "status" from examplesRob Herring
Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>

The RTC can output its 32kHz clock outside of the SoC, for example to clock a WiFi chip. Create a new clock that other devices will be able to retrieve, while maintaining the DT stability by providing a default name for that clock if clock-output-names doesn't list one.

2017-02-21rtc: armada38x: Add support for Armada 7K/8KGregory CLEMENT
The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC integration differs in 2 points: - MBUS bridge timing initialization - IRQ configuration at SoC level Moreover the Armada 7K/8K have an issue preventing to get the interrupt from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to still use alarm 1 for the Armada 38x.

2017-02-12bindings: rtc: correct wrong reference in required propertiesAkinobu Mita
There are currently two broken bindings descriptions for RTC: maxim,ds3231.txt pcf8563.txt They broke because of a improper RST documentation conversion with commit 8c27ceff3604b2 ("docs: fix locations of several documents that got moved") and now reference to a non-existing file: Documentation/devicetree/bindings/i2c/trivial-admin-guide/devices.rst However, the original reference to i2c/trivial-devices should have never been made in the first place. This change fixes this issue by replacing with correct descriptions.

2017-02-01rtc: sun6i: Expose the 32kHz oscillatorMaxime Ripard
The RTC controls the input source of the main 32kHz oscillator in the system, feeding it to the clock unit too. By default, this is using an internal, very inaccurate (+/- 30%) oscillator with a divider to make it roughly around 32kHz. This is however quite impractical for the RTC, since our time will not be tracked properly. Since this oscillator is an input of the main clock unit, and since that clock unit will be probed using CLK_OF_DECLARE, we have to use it as well, leading to a two stage probe: one to enable the clock, the other one to enable the RTC. There is also a slight change in the binding that is required (and should have been from the beginning), since we'll need a phandle to the external oscillator used on that board. We support the old binding by not allowing to switch to the external oscillator and only using the internal one (which was the previous behaviour) in the case where we're missing that phandle.

2015-11-08rtc: pcf8563: add CLKOUT to common clock frameworkHeiko Schocher
Add the clkout output clk to the common clock framework. Disable the CLKOUT of the RTC after power-up. After power-up/reset of the RTC, CLKOUT is enabled by default, with CLKOUT enabled the RTC chip has 2-3 times higher power consumption.

This patch marks all the reference to the legacy wakeup bindings and replaces them with the standard "wakeup-source" property. All these legacy property are also listed under a separate section in the generic wakeup-source binding document.
