2019-11-28dt-bindings: i2c: support property idle-stateBiwen Li
This supports property idle-state Signed-off-by: Biwen Li <biwen.li@nxp.com> Reviewed-by: Rob Herring <robh@kernel.org>
2018-12-11dt-bindings: i2c: Use correct vendor prefix for AtmelThierry Reding
The "at," prefix was never correct for Atmel, so fix the few occurrences that got it wrong. Use "atmel," instead.

2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

2017-12-30i2c: mux: pca954x: add support for NXP PCA984x familyAdrian Fiergolski
This patch extends the current i2c-mux-pca954x driver and adds support for a newer PCA984x family of the I2C switches and multiplexers from NXP. Signed-off-by: Adrian Fiergolski <adrian.fiergolski@cern.ch> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Peter Rosin <peda@axentia.se>
2017-02-10dt: bindings: i2c-mux-pca954x: Add documentation for interrupt controllerPhil Reid
Various muxes can aggregate multiple irq lines and provide a control register to determine the active line. Add bindings for interrupt controller support. Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Phil Reid <preid@electromag.com.au> Signed-off-by: Peter Rosin <peda@axentia.se>
2015-01-23of: i2c: Add i2c-mux-idle-disconnect DT property to PCA954x mux driverAlexander Sverdlin
Add i2c-mux-idle-disconnect device tree property to PCA954x mux driver. The new property forces the multiplexer to disconnect child buses in idle state. This is used, for example, when there are several multiplexers on the same bus and the devices on the underlying buses might have same I2C addresses.
