* net/smsc911x: Repair broken failure pathsLee Jones2012-05-301-3/+4
| | | | | | | | | | | | Current failure paths attempt to free resources which we failed to request and disable resources which we failed to enable ones. This leads to kernel oops/panic. This patch does some simple re-ordering to prevent this from happening.

| * net: smsc911x: fix skb handling in receive pathWill Deacon2012-04-131-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SMSC911x driver resets the ->head, ->data and ->tail pointers in the skb on the reset path in order to avoid buffer overflow due to packet padding performed by the hardware. This patch fixes the receive path so that the skb pointers are fixed up after the data has been read from the device, The error path is also fixed to use number of words consistently and prevent erroneous FIFO fastforwarding when skipping over bad data.

* net/smsc911x: Check if PHY is in operational mode before software resetJavier Martinez Canillas2012-01-031-0/+92
| | | | | | | | | | | | | | | | | | | | | SMSC LAN generation 4 chips integrate an IEEE 802.3 ethernet physical layer. The PHY driver for this integrated chip enable an energy detect power-down mode. When the PHY is in a power-down mode, it prevents the MAC portion chip to be software reseted. That means that if we compile the kernel with the configuration option SMSC_PHY enabled and try to bring the network interface up without an cable plug-ed the PHY will be in a low power mode and the software reset will fail returning -EIO to user-space: root@igep00x0:~# ifconfig eth0 up ifconfig: SIOCSIFFLAGS: Input/output error This patch disable the energy detect power-down mode before trying to software reset the LAN chip and re-enables after it was reseted successfully.

* net/smsc911x: Add regulator supportRobert Marklund2011-11-291-11/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add some basic regulator support for the power pins, as needed by the ST-Ericsson Snowball platform that powers up the SMSC911 chip using an external regulator. Platforms that use regulators and the smsc911x and have no defined regulator for the smsc911x and claim complete regulator constraints with no dummy regulators will need to provide it, for example using a fixed voltage regulator. It appears that this may affect (apart from Ux500 Snowball) possibly these archs/machines that from some grep:s appear to define both CONFIG_SMSC911X and CONFIG_REGULATOR: - ARM Freescale mx3 and OMAP 2 plus, Raumfeld machines - Blackfin - Super-H Cc: Paul Mundt <lethal@linux-sh.org> Cc: linux-sh@vger.kernel.org Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Tony Lindgren <tony@atomide.com> Cc: linux-omap@vger.kernel.org Cc: Mike Frysinger <vapier@gentoo.org> Cc: uclinux-dist-devel@blackfin.uclinux.org Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Robert Marklund <robert.marklund@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: David S.

* net/smsc911x: Always wait for the chip to be readyRobert Marklund2011-11-141-0/+12
| | | | | | | | | | | Wait for the chip to be ready before any access to it. On the Snowball platform we need to enable an external regulator before the chip comes online, and then it happens that the device is not yet ready at probe time, so let's wait for it.

* net/smsc911x: Correctly configure 16-bit register access from DTDave Martin2011-09-211-0/+2
| | | | | | | | | | | | | | | The SMSC911X_USE_16BIT needs to be set when using 16-bit register access. However, currently no flag is set if the device tree doesn't specify 32-bit access, resulting in a BUG() and a non- working driver when 16-bit register access is configured for smsc911x in the DT. This patch should set the SMSC911X_USE_16BIT flag in a manner consistent with the documented DT bindings.
