dt-bindings: net: Add a YAML schemas for the generic PHY options

2019-06-28T19:27:45Z

The networking PHYs have a number of available device tree properties that can be used in their device tree node. Add a YAML schemas for those. Reviewed-by: Andrew Lunn Reviewed-by: Rob Herring Signed-off-by: Maxime Ripard [robh: drop maxItems from reg] Signed-off-by: Rob Herring

dt-bindings: remove 'interrupt-parent' from bindings

2018-07-25T20:09:39Z

'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.

phylib: rename reset-(post-)delay-us to reset-(de)assert-us

As suggested by Rob Herring [1] rename the previously introduced reset-{,post-}delay-us bindings to the clearer reset-{,de}assert-us [1] https://patchwork.kernel.org/patch/10104905/ Signed-off-by: Richard Leitner Reviewed-by: Rob Herring Signed-off-by: David S. Miller

phylib: Add device reset delay support

2017-12-13T16:22:53Z

Some PHYs need a minimum time after the reset gpio was asserted and/or deasserted. To ensure we meet these timing requirements add two new optional devicetree parameters for the phy: reset-delay-us and reset-post-delay-us.

phylib: Add device reset GPIO support

2017-12-05T17:51:19Z

The PHY devices sometimes do have their reset signal (maybe even power supply?) tied to some GPIO and sometimes it also does happen that a boot loader does not leave it deasserted. So far this issue has been attacked from (as I believe) a wrong angle: by teaching the MAC driver to manipulate the GPIO in question; that solution, when applied to the device trees, led to adding the PHY reset GPIO properties to the MAC device node, with one exception: Cadence MACB driver which could handle the "reset-gpios" prop in a PHY device subnode. I believe that the correct approach is to teach the 'phylib' to get the MDIO device reset GPIO from the device tree node corresponding to this device -- which this patch is doing... Note that I had to modify the AT803x PHY driver as it would stop working otherwise -- it made use of the reset GPIO for its own purposes...

Pull DeviceTree updates from Rob Herring: "There's a few orphans in the conversion to %pOF printf specifiers included here that no one else picked up. Summary: - Convert more DT code to use of_property_read_* API. - Improve DT overlay support when adding multiple overlays - Convert printk's to %pOF format specifiers. Most went via subsystem trees, but picked up the remaining orphans - Correct unittests to use preferred "okay" for "status" property value - Add a KASLR seed property - Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa - Fix modalias buffer handling - Clean-up of include paths for building dtbs - Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10 devices - Add nvmem bindings for MediaTek MT7623 and MT7622 SoC - Add compatible string for Allwinner H5 Mali-450 GPU - Fix links to old OpenFirmware docs with new mirror on devicetree.org - Remove status property from binding doc examples" * tag 'devicetree-for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (45 commits) devicetree: Adjust status "ok" -> "okay" under drivers/of/ dt-bindings: Remove "status" from examples dt-bindings: pinctrl: sh-pfc: Use generic node name dt-bindings: Add vendor Mellanox dt-binding: net/phy: fix interrupts description virt: Convert to using %pOF instead of full_name macintosh: Convert to using %pOF instead of full_name ide: pmac: Convert to using %pOF instead of full_name microblaze: Convert to using %pOF instead of full_name dt-bindings: usb: musb: Grammar s/the/to/, s/is/are/ of: Use PLATFORM_DEVID_NONE definition of/device: Fix of_device_get_modalias() buffer handling of/device: Prevent buffer overflow in of_device_modalias() dt-bindings: add amc6821, isl1208 trivial bindings dt-bindings: add vendor prefix for Theobroma Systems of: search scripts/dtc/include-prefixes path for both CPP and DTC of: remove arch/$(SRCARCH)/boot/dts from include search path for CPP of: remove drivers/of/testcase-data from include search path for CPP of: return of_get_cpu_node from of_cpu_device_node_get if CPUs are not registered iio: srf08: add device tree binding for srf02 and srf10 ...

dt-binding: net/phy: fix interrupts description

2017-08-29T17:13:40Z

Commit b053dc5a722ea (powerpc: Refactor device tree binding) split the Ethernet PHY binding documentation out of the big booting-without-of.txt file, leaving a dangling reference to "section 2" in the 'interrupts' property description. Drop that reference, and make the description look more like the rest. While at it, make the example interrupt-parent phandle look more like a real world phandle, and use an IRQ_TYPE_ macro for the 'interrupts' type.

Documentation: net: phy: Add phy-is-integrated binding

2017-08-11T21:28:58Z

Add the documentation for integrated PHY. A boolean property indicates the PHY is integrated into the same physical package as the Ethernet MAC. If needed, muxers should be configured to ensure the integrated PHY is used. The absence of this property indicates the muxers should be configured so that the external PHY is used.

Documentation: devicetree: Add PHY no lane swap binding

2017-02-07T18:59:27Z

Add the documentation to avoid PHY lane swapping. This is a boolean entry to notify the phy device drivers that the TX/RX lanes NO need to be swapped. The use case for this binding mostly happens after wrong HW configuration of PHY IC during bootstrap. Signed-off-by: Lukasz Majewski Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller
