2022-05-01dt-bindings: net: phy: Add 10-baseT1L 2.4 VppAlexandru Tachici1-0/+9
Add a tristate property to advertise desired transmit level. If the device supports the 2.4 Vpp operating mode for 10BASE-T1L, as defined in 802.3gc, and the 2.4 Vpp transmit voltage operation is desired, property should be set to 1. This property is used to select whether Auto-Negotiation advertises a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to 1, the PHY shall advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to zero, the PHY shall not advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode.

2022-04-30dt-bindings: net: lan966x: remove PHY resetMichael Walle1-2/+0
The PHY reset was intended to be a phandle for a special PHY reset driver for the integrated PHYs as well as any external PHYs. It turns out, that the culprit is how the reset of the switch device is done. In particular, the switch reset also affects other subsystems like the GPIO and the SGPIO block and it happens to be the case that the reset lines of the external PHYs are connected to a common GPIO line. Thus as soon as the switch issues a reset during probe time, all the external PHYs will go into reset because all the GPIO lines will switch to input and the pull-down on that signal will take effect. So even if there was a special PHY reset driver, it (1) won't fix the root cause of the problem and (2) it won't fix all the other consumers of GPIO lines which will also be reset. It turns out, the Ocelot SoC has the same weird behavior (or the lack of a dedicated switch reset) and there the problem is already solved and all the bits and pieces are already there and this PHY reset property isn't not needed at all. There are no users of this binding. Just remove it. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: David S. Miller <davem@davemloft.net>

The AST2600 MDIO bus controller has a reset control bit and must be deasserted before manipulating the MDIO controller. By default, the hardware asserts the reset so the driver only need to deassert it. Regarding to the old DT blobs which don't have reset property in them, the reset deassertion is usually done by the bootloader so the reset property is optional to work with them.

Looks like all the changes to this driver had been automated churn since git era begun. The driver is using virt_to_bus() so it should be updated to a proper DMA API or removed. Given the latest "news" entry on the website is from 1999 I'm opting for the latter.

The first 2 patches are by me and target the CAN driver infrastructure. One patch renames a function in the rx_offload helper the other one updates the CAN bitrate calculation to prefer small bit rate pre-scalers over larger ones, which is encouraged by the CAN in Automation. Kris Bahnsen contributes a patch to fix the links to Technologic Systems web resources in the sja1000 driver. Christophe Leroy's patch prepares the mpc5xxx_can driver for upcoming powerpc header cleanup. Minghao Chi's patch converts the flexcan driver to use pm_runtime_resume_and_get(). The next 2 patches target the Xilinx CAN driver. Lukas Bulwahn's patch fixes an entry in the MAINTAINERS file. A patch by me marks the bit timing constants as const. Wolfram Sang's patch documents r8a77961 support on the renesas,rcar-canfd bindings document. The next 2 patches are by me and add support for the mcp251863 chip to the mcp251xfd driver.

Compatible strings are used to help the driver find the chip ID/version register for each chip family. After that, the driver can setup the switch accordingly. Keep only the first supported model for each family as a compatible string and reference other chip models in the description. The removed compatible strings have never been used in a released kernel.

2022-04-18devlink: implement line card provisioningJiri Pirko2-0/+122
In order to be able to configure all needed stuff on a port/netdevice of a line card without the line card being present, introduce line card provisioning. Basically by setting a type, provisioning process will start and driver is supposed to create a placeholder for instances (ports/netdevices) for a line card type. Allow the user to query the supported line card types over line card get command. Then implement two netlink command SET to allow user to set/unset the card type. On the driver API side, add provision/unprovision ops and supported types array to be advertised. Upon provision op call, the driver should take care of creating the instances for the particular line card type. Introduce provision_set/clear() functions to be called by the driver once the provisioning/unprovisioning is done on its side. These helpers are not to be called directly due to the async nature of provisioning. Example: $ devlink port # No ports are listed $ devlink lc pci/0000:01:00.0: lc 1 state unprovisioned supported_types: 16x100G lc 2 state unprovisioned supported_types: 16x100G lc 3 state unprovisioned supported_types: 16x100G lc 4 state unprovisioned supported_types: 16x100G lc 5 state unprovisioned supported_types: 16x100G lc 6 state unprovisioned supported_types: 16x100G lc 7 state unprovisioned supported_types: 16x100G lc 8 state unprovisioned supported_types: 16x100G $ devlink lc set pci/0000:01:00.0 lc 8 type 16x100G $ devlink lc show pci/0000:01:00.0 lc 8 pci/0000:01:00.0: lc 8 state active type 16x100G supported_types: 16x100G $ devlink port pci/0000:01:00.0/0: type notset flavour cpu port 0 splittable false pci/0000:01:00.0/53: type eth netdev enp1s0nl8p1 flavour physical lc 8 port 1 splittable true lanes 4 pci/0000:01:00.0/54: type eth netdev enp1s0nl8p2 flavour physical lc 8 port 2 splittable true lanes 4 pci/0000:01:00.0/55: type eth netdev enp1s0nl8p3 flavour physical lc 8 port 3 splittable true lanes 4 pci/0000:01:00.0/56: type eth netdev enp1s0nl8p4 flavour physical lc 8 port 4 splittable true lanes 4 pci/0000:01:00.0/57: type eth netdev enp1s0nl8p5 flavour physical lc 8 port 5 splittable true lanes 4 pci/0000:01:00.0/58: type eth netdev enp1s0nl8p6 flavour physical lc 8 port 6 splittable true lanes 4 pci/0000:01:00.0/59: type eth netdev enp1s0nl8p7 flavour physical lc 8 port 7 splittable true lanes 4 pci/0000:01:00.0/60: type eth netdev enp1s0nl8p8 flavour physical lc 8 port 8 splittable true lanes 4 pci/0000:01:00.0/61: type eth netdev enp1s0nl8p9 flavour physical lc 8 port 9 splittable true lanes 4 pci/0000:01:00.0/62: type eth netdev enp1s0nl8p10 flavour physical lc 8 port 10 splittable true lanes 4 pci/0000:01:00.0/63: type eth netdev enp1s0nl8p11 flavour physical lc 8 port 11 splittable true lanes 4 pci/0000:01:00.0/64: type eth netdev enp1s0nl8p12 flavour physical lc 8 port 12 splittable true lanes 4 pci/0000:01:00.0/125: type eth netdev enp1s0nl8p13 flavour physical lc 8 port 13 splittable true lanes 4 pci/0000:01:00.0/126: type eth netdev enp1s0nl8p14 flavour physical lc 8 port 14 splittable true lanes 4 pci/0000:01:00.0/127: type eth netdev enp1s0nl8p15 flavour physical lc 8 port 15 splittable true lanes 4 pci/0000:01:00.0/128: type eth netdev enp1s0nl8p16 flavour physical lc 8 port 16 splittable true lanes 4 $ devlink lc set pci/0000:01:00.0 lc 8 notype Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.
