The Allwinner A10/A20 SoCs have an on-board CAN (Controller Area Network) controller. This patch adds the CAN core to the SoC's include files, sun4i-a10.dtsi and sun7i-a20.dtsi. On linux-can mailing list was a discussion about updating the device tree bindings https://lkml.org/lkml/2015/9/17/220 but it did not progress past writing the documentation file. Documentation/devicetree/bindings/net/can/sun4i_can.txt The CAN controller can be enabled in a board specific dts file as described in the documentation file or by using a device tree overlay. I have tested the patch on a Banana Pi (A20 SoC) with mainline kernel 4.10.5. History: v4: fixed style problems, changed device node position of ps20 and ps21 to fix ordering by rising physical address v3: added "allwinner,sun7i-a20-can" compatible to can0 device node contents, make separate patches for device nodes and pinctrl settings v2: changed can0_pins_a node contents to new generic binding method, changed can0_pins_a node position by alphabetical order, changed can0 device node position by rising physical address order v1: initial Patrick Menschel (6): ARM: dts: sun4i: fix device node ordering ARM: dts: sun4i: Add CAN node ARM: dts: sun4i: Add can0_pins_a pinctrl settings ARM: dts: sun7i: fix device node ordering ARM: dts: sun7i: Add CAN node ARM: dts: sun7i: Add can0_pins_a pinctrl settings arch/arm/boot/dts/sun4i-a10.dtsi | 38 ++++++++++++++++++++++----------- arch/arm/boot/dts/sun7i-a20.dtsi | 45 ++++++++++++++++++++++++++-------------- 2 files changed, 56 insertions(+), 27 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
