* dt-bindings: Use lower case hex in unit-addressesRob Herring2017-12-261-1/+1
| | | | | | | | | | | DT unit addresses should be lower case hex. Fix all the binding examples. Converted with the following command from Krzysztof Kozlowski: sed -e 's/@\([a-fA-F0-9_-]*\) {/@\L\1 {/' -i $(find Documentation/devicetree/bindings -name '*.txt') Signed-off-by: Rob Herring <robh@kernel.org>
* bindings: mfd: cros ec: Document vbc EC propertyEmilio López2015-10-301-0/+4
| | | | | | | | | | Some EC implementations include a small nvram space used to store verified boot context data. This boolean property lets us indicate whether this space is available or not on a specific EC implementation.

* mfd: cros_ec: spi: Add a DT property to delay asserting the CSAlexandru M Stan2015-06-151-0/+4
| | | | | | | | | | | | | | | | | | | Some ECs need a little time for waking up before they can accept SPI data at a high speed. Add a "google,cros-ec-spi-pre-delay" property to the DT binding to configure this. If this property isn't set, then no delay will be added. However, if set it will cause a delay equal to the value passed to it to be inserted at the beginning of a transaction.

* mfd: cros ec: spi: Add delay for raising CSRhyland Klein2014-01-211-0/+9
| | | | | | | | | | | | | | | | | The EC has specific timing it requires. Add support for an optional delay after raising CS to fix timing issues. This is configurable based on a DT property "google,cros-ec-spi-msg-delay". If this property isn't set, then no delay will be added. However, if set it will cause a delay equal to the value passed to it to be inserted at the end of a transaction.

* mfd: Add ChromeOS EC implementationSimon Glass2013-04-051-0/+56
This is the base EC implementation, which provides a high level interface to the EC for use by the rest of the kernel. The actual communcations is dealt with by a separate protocol driver which registers itself with this interface. Interrupts are passed on through a notifier. A simple message structure is used to pass messages to the protocol driver.
