2016-01-07mdio: Move allocation of interrupts into coreAndrew Lunn1-13/+1
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.

2016-01-07phy: Centralise print about attached phyAndrew Lunn1-3/+1
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 <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine1-1/+1
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2014-03-28r6040: remove empty MDIO bus reset functionFlorian Fainelli1-6/+0

2014-01-16r6040: use ETH_ZLEN instead of MISR for SKB length checkingFlorian Fainelli1-2/+2
Ever since this driver was merged the following code was included: if (skb->len < MISR) skb->len = MISR; MISR is defined to 0x3C which is also equivalent to ETH_ZLEN, but use ETH_ZLEN directly which is exactly what we want to be checking for.

2014-01-16r6040: add delays in MDIO read/write polling loopsFlorian Fainelli1-0/+2
On newer and faster machines (Vortex X86DX) using the r6040 driver, it was noticed that the driver was returning an error during probing traced down to being the MDIO bus probing and the inability to complete a MDIO read operation in time. It turns out that the MDIO operations on these faster machines usually complete after ~2140 iterations which is bigger than 2048 (MAC_DEF_TIMEOUT) and results in spurious timeouts depending on the system load. Update r6040_phy_read() and r6040_phy_write() to include a 1 micro second delay in each busy-looping iteration of the loop which is a much safer operation than incrementing MAC_DEF_TIMEOUT.

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>.

2013-03-09drivers:net: Remove unnecessary OOM messages after netdev_alloc_skbJoe Perches1-1/+0
Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM messages is unnecessary as there is already a dump_stack after allocation failures. Other trivial changes around these removals: Convert a few comparisons of pointer to 0 to !pointer. Change flow to remove unnecessary label. Remove now unused variable. Hoist assignment from if.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli1-1/+1
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.

Commit 4e16d6ebd65b4f2c4e3f780b4c5704beef64019c (r6040: define more MCR0 register bits) added #define values for MCR0 register bits and converted uses of hardcoded magic values to uses of these defines. However, one of the conversions looks suspicious: #define MCR0 0x00 /* Control register 0 */ +#define MCR0_RCVEN 0x0002 /* Receive enable */ +#define MCR0_XMTEN 0x1000 /* Transmission enable */ /* Init RDC private data */ - lp->mcr0 = 0x1002; + lp->mcr0 = MCR0_XMTEN | MCR0; I believe what was meant here was MCR0_XMTEN | MCR0_RCVEN, which makes sense and matches the original values.
