Changes since v2: - Fixed changes in phy-can-transceiver based on comments - added select MULTIPLEXER in drivers/phy/Kconfig - Changed the implemetation of getting state by adding new apis Changes since v1: - Added support for reading the enable state from DT instead of hardcoding the state to be set to 1. - Made relavent changes in the bindings Link to v2: - https://patchwork.kernel.org/project/linux-phy/list/?series=583917 Link to v1, - https://patchwork.kernel.org/project/linux-phy/list/?series=578863&state=* Aswath Govindraju (4): dt-bindings: mux: Increase the number of arguments in mux-controls dt-bindings: phy: ti,tcan104x-can: Document mux-controls property mux: Add support for reading mux enable state from DT phy: phy-can-transceiver: Add support for setting mux .../devicetree/bindings/mux/gpio-mux.yaml | 2 +- .../bindings/mux/mux-controller.yaml | 2 +- .../bindings/phy/ti,tcan104x-can.yaml | 8 + drivers/mux/core.c | 146 +++++++++++++++++- drivers/phy/Kconfig | 1 + drivers/phy/phy-can-transceiver.c | 22 +++ include/linux/mux/consumer.h | 19 ++- include/linux/mux/driver.h | 13 ++ 8 files changed, 206 insertions(+), 7 deletions(-)
