net: smc911x: avoid unused variable warnings

2016-03-21T15:26:12+00:00

The change to use the generic DMA engine API in the smc911x driver has led to a harmless warning about unused local variables: smsc/smc911x.c: In function 'smc911x_probe': smsc/smc911x.c:1796:20: error: unused variable 'param' smsc/smc911x.c:1795:17: error: unused variable 'mask' smsc/smc911x.c:1794:26: error: unused variable 'config' This puts the variable declarations inside of the same #ifdef that protects their use.

net: smc911x: convert pxa dma to dmaengine

2016-03-19T02:23:59+00:00

Convert the dma transfers to be dmaengine based, now pxa has a dmaengine slave driver. This makes this driver a bit more PXA agnostic. The driver was only compile tested. The risk is quite small as no current PXA platform I'm aware of is using smc911x driver. Signed-off-by: Robert Jarzmik Tested-by: Fabio Estevam Signed-off-by: David S. Miller

smc91x: avoid self-comparison warning

2016-03-14T23:37:03+00:00

The smc91x driver defines a macro that compares its argument to itself, apparently to get a true result while using its argument to avoid a warning about unused local variables. Unfortunately, this triggers a warning with gcc-6, as the comparison is obviously useless: drivers/net/ethernet/smsc/smc91x.c: In function 'smc_hardware_send_pkt': drivers/net/ethernet/smsc/smc91x.c:563:14: error: self-comparison always evaluates to true [-Werror=tautological-compare] if (!smc_special_trylock(&lp->lock, flags)) { This replaces the macro with another one that behaves similarly, with a cast to (void) to ensure the argument is used, and using a literal 'true' as its value.

net: smc91x: propagate irq return code

2016-02-16T20:02:23+00:00

The smc91x driver doesn't honor the probe deferral mechanism when the interrupt source is not yet available, such as one provided by a gpio controller not probed. Fix this by propagating the platform_get_irq() error code as the probe return value. Signed-off-by: Robert Jarzmik Cc: Sergei Shtylyov Signed-off-by: David S. Miller

phy: Add API for {un}registering an mdio device to a bus.

2016-01-07T19:31:26+00:00

Rather than have drivers directly manipulate the mii_bus structure, provide and API for registering and unregistering devices on an MDIO bus, and performing lookups. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

phy: Add an mdio_device structure

2016-01-07T19:31:26+00:00

Not all devices attached to an MDIO bus are phys. So add an mdio_device structure to represent the generic parts of an mdio device, and place this structure into the phy_device. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

mdio: Move allocation of interrupts into core

2016-01-07T19:31:26+00:00

Have mdio_alloc() create the array of interrupt numbers, and initialize it to POLLING. This is what most MDIO drivers want, so allowing code to be removed from the drivers. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

phy: Centralise print about attached phy

2016-01-07T19:31:25+00:00

Many Ethernet drivers contain the same netdev_info() print statement about the attached phy. Move it into the phy device code. Additionally add a varargs function which can be used to append additional information. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

phy: add phydev_name() wrapper

2016-01-07T19:31:25+00:00

Add a phydev_name() function, to help with moving some structure members from phy_device. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller
