2019-04-04rtc: pcf85063: add Micro Crystal RV8263 supportAlexandre Belloni
The Micro Crystal RV8263 has the same IC as the pcf85063 but has an on board crystal. This means that the CAP_SEL bit has to be cleared so the correct capacitance is selected for the crystal. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2018-12-06dt-bindings: rtc: sun6i-rtc: Add compatible strings for pre-H6 variantsChen-Yu Tsai
While doing Bluetooth enablement for various boards based on various Allwinner SoCs, minor differences in the RTC modules were found. These include a lack of an external clock output (A31), different internal oscillator frequencies (H3/H5/A64/V3/V3s), different regulator voltage settings (H5/H6), and the presence of miscellaneous registers unrelated to the RTC (A64/R40/H5/H6). The datasheet also describes different number of registers for non-volatile storage, though based on actual experiments the actual number is the same across the board. This patch adds a list of all pre-H6 variants, grouped by the internal oscillator's clock rate, regulator settings, and the presence of the external clock output. Combinations are introduced for the variants that have miscellaneous registers. The RTC block in the H6 also handles the 24 MHz DCXO. This will require more device tree binding changes and will be done later.

The clock output section for this binding describes the two outputs in the descriptions for both the #clock-cells and clock-output-names properties. Instead of overlapping information that is hard to read, rewrite the clock outputs as a list of indices and descriptions. The properies can reference this list instead. This will also make it easier to add notes or conditions to the clocks, and also for adding new outputs.

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>
