2024-02-13dt-bindings: ufs: samsung,exynos-ufs: Add size constraints on "samsung,sysreg"Gravatar Rob Herring 1-3/+6
The 'phandle-array' type is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. "samsung,sysreg" is the latter and needs to be constrained to a single entry with a phandle and offset.

2024-02-12can: bcm: add recvmsg flags for own, local and remote trafficGravatar Nicolas Maier 1-16/+18
CAN RAW sockets allow userspace to tell if a received CAN frame comes from the same socket, another socket on the same host, or another host. See commit 1e55659ce6dd ("can-raw: add msg_flags to distinguish local traffic"). However, this feature is missing in CAN BCM sockets. Add the same feature to CAN BCM sockets. When reading a received frame (opcode RX_CHANGED) using recvmsg, two flags in msg->msg_flags may be set following the previous convention (from CAN RAW), to distinguish between 'own', 'local' and 'remote' CAN traffic. Update the documentation to reflect this change.

Document ethernet PHY package nodes used to describe PHY shipped in bundle of 2-5 PHY. The special node describe a container of PHY that share common properties. This is a generic schema and PHY package should create specialized version with the required additional shared properties. Example are PHY packages that have some regs only in one PHY of the package and will affect every other PHY in the package, for example related to PHY interface mode calibration or global PHY mode selection. The PHY package node MUST declare the base address used by the PHY driver for global configuration by calculating the offsets of the global PHY based on the base address of the PHY package. Each reg of the PHYs defined in the PHY package node is absolute and describe the real address of the Ethernet PHY on the bus.

2024-02-06bonding: Add independent control state machineGravatar Aahil Awatramani 1-0/+12
Add support for the independent control state machine per IEEE 802.1AX-2008 5.4.15 in addition to the existing implementation of the coupled control state machine. Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in the LACP MUX state machine for separated handling of an initial Collecting state before the Collecting and Distributing state. This enables a port to be in a state where it can receive incoming packets while not still distributing. This is useful for reducing packet loss when a port begins distributing before its partner is able to collect. Added new functions such as bond_set_slave_tx_disabled_flags and bond_set_slave_rx_enabled_flags to precisely manage the port's collecting and distributing states. Previously, there was no dedicated method to disable TX while keeping RX enabled, which this patch addresses. Note that the regular flow process in the kernel's bonding driver remains unaffected by this patch. The extension requires explicit opt-in by the user (in order to ensure no disruptions for existing setups) via netlink support using the new bonding parameter coupled_control. The default value for coupled_control is set to 1 so as to preserve existing behaviour.

The example for PCI devices has some addressing errors. 'reg' is written as if the parent bus is PCI, but the default bus for examples is 1 address and size cell. 'ranges' is defining config space with a size of 0. Generally, config space should not be defined in 'ranges', only PCI memory and I/O spaces. Fix these issues by updating the values with made-up, but valid values. This was uncovered with recent dtschema changes.

This commit adds the dt-binding for KSZ8567, a robust 7-port Ethernet switch. The KSZ8567 features two RGMII/MII/RMII interfaces, each capable of gigabit speeds, complemented by five 10/100 Mbps MAC/PHYs. This binding is necessary to set specific capabilities for this switch chip that are necessary due to the ksz dsa driver only accepting specific chip ids. The KSZ8567 is very similar to KSZ9567 however only containing 100 Mbps phys on its downstream ports.
