net: renesas: rswitch: add offloading for L2 switching

2025-09-04T07:43:23+00:00

Add hardware offloading for L2 switching on R-Car S4.

On S4 brdev is limited to one per-device (not per port). Reasoning
is that hw L2 forwarding support lacks any sort of source port based
filtering, which makes it unusable to offload more than one bridge
device. Either you allow hardware to forward destination MAC to a
port, or you have to send it to CPU. You can't make it forward only
if src and dst ports are in the same brdev.

net: renesas: rswitch: rename rswitch.c to rswitch_main.c

2025-09-04T07:43:23+00:00

Adding new functionality to the driver. Therefore splitting into multiple
c files to keep them manageable. New functionality will be added to
separate files.

net: ethernet: rtsn: Add support for Renesas Ethernet-TSN

2024-06-21T11:24:54+00:00

Add initial support for Renesas Ethernet-TSN End-station device of R-Car
V4H. The Ethernet End-station can connect to an Ethernet network using a
10 Mbps, 100 Mbps, or 1 Gbps full-duplex link via MII/GMII/RMII/RGMII.
Depending on the connected PHY.

The driver supports Rx checksum and offload and hardware timestamps.

While full power management and suspend/resume is not yet supported the
driver enables runtime PM in order to enable the module clock. While
explicit clock management using clk_enable() would suffice for the
supported SoC, the module could be reused on SoCs where the module is
part of a power domain.

net: ethernet: renesas: rcar_gen4_ptp: Break out to module

2023-11-23T11:02:49+00:00

The Gen4 gPTP support will be shared between the existing Renesas
Ethernet Switch driver and the upcoming Renesas Ethernet-TSN driver. In
preparation for this break out the gPTP support to its own module.

net: ethernet: renesas: Add support for "Ethernet Switch"

2022-11-02T12:38:53+00:00

Add initial support for Renesas "Ethernet Switch" device of R-Car S4-8.
The hardware has features about forwarding for an ethernet switch
device. But, for now, it acts as ethernet controllers so that any
forwarding offload features are not supported. So, any switchdev
header files and DSA framework are not used.

Renesas Ethernet AVB PTP clock driver

2015-06-11T07:24:12+00:00

Ethernet AVB device includes the gPTP  timer, so we can implement a PTP clock
driver.  We're doing that in a separate file, with  the main Ethernet driver
calling the PTP driver's [de]initialization and interrupt handler functions.
Unfortunately, the clock seems tightly coupled with the AVB-DMAC, so when that
one leaves the operation mode, we have to unregister the PTP clock... :-(

Renesas Ethernet AVB driver proper

2015-06-11T07:14:29+00:00

Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically
compatible with SuperH Gigabit Ethernet E-MAC.  Ethernet AVB has  a  dedicated
direct memory access controller (AVB-DMAC) that is a new design compared to the
SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE
802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real-
time transfer, and the IEEE 802.1Qat stream reservation protocol.

The  driver only supports device tree probing, so the binding document is
included in this patch.
