net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

net: sh_eth: Fix PHY state warning splat during system resume

Since commit 744d23c71af39c7d ("net: phy: Warn about incorrect mdio_bus_phy_resume() state"), a warning splat is printed during system resume with Wake-on-LAN disabled: WARNING: CPU: 0 PID: 626 at drivers/net/phy/phy_device.c:323 mdio_bus_phy_resume+0xbc/0xe4 As the Renesas SuperH Ethernet driver already calls phy_{stop,start}() in its suspend/resume callbacks, it is sufficient to just mark the MAC responsible for managing the power state of the PHY.

net: ravb: Add R-Car Gen4 support

2022-09-20T00:58:17Z

Add support for the Renesas Ethernet AVB (EtherAVB-IF) blocks on R-Car Gen4 SoCs (e.g. R-Car V4H) by matching on a family-specific compatible value. These are treated the same as EtherAVB on R-Car Gen3.

ravb: Add support for RZ/V2M

2022-05-16T09:14:27Z

RZ/V2M Ethernet is very similar to R-Car Gen3 Ethernet-AVB, though some small parts are the same as R-Car Gen2. Other differences to R-Car Gen3 and Gen2 are: * It has separate data (DI), error (Line 1) and management (Line 2) irqs rather than one irq for all three. * Instead of using the High-speed peripheral bus clock for gPTP, it has a separate gPTP reference clock.

ravb: Use separate clock for gPTP

2022-05-16T09:14:27Z

RZ/V2M has a separate gPTP reference clock that is used when the AVB-DMAC Mode Register (CCC) gPTP Clock Select (CSEL) bits are set to "01: High-speed peripheral bus clock". Therefore, add a feature that allows this clock to be used for gPTP. Signed-off-by: Phil Edworthy Reviewed-by: Biju Das Reviewed-by: Sergey Shtylyov Signed-off-by: David S. Miller

ravb: Support separate Line0 (Desc), Line1 (Err) and Line2 (Mgmt) irqs

2022-05-16T09:14:27Z

R-Car has a combined interrupt line, ch22 = Line0_DiA | Line1_A | Line2_A. RZ/V2M has separate interrupt lines for each of these, so add a feature that allows the driver to get these interrupts and call the common handler.

ravb: Separate handling of irq enable/disable regs into feature

2022-05-16T09:14:27Z

Currently, when the HW has a single interrupt, the driver uses the GIC, TIC, RIC0 registers to enable and disable interrupts. When the HW has multiple interrupts, it uses the GIE, GID, TIE, TID, RIE0, RID0 registers. However, other devices, e.g. RZ/V2M, have multiple irqs and only have the GIC, TIC, RIC0 registers. Therefore, split this into a separate feature. Signed-off-by: Phil Edworthy Reviewed-by: Biju Das Reviewed-by: Sergey Shtylyov Signed-off-by: David S. Miller
