2013-09-03net: emac: use platform_{get,set}_drvdata()Jingoo Han
Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. This is a purely cosmetic change. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-29drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherentJoe Perches
__GFP_ZERO is an uncommon flag and perhaps is better not used. static inline dma_zalloc_coherent exists so convert the uses of dma_alloc_coherent with __GFP_ZERO to the more common kernel style with zalloc. Remove memset from the static inline dma_zalloc_coherent and add just one use of __GFP_ZERO instead. Trivially reduces the size of the existing uses of dma_zalloc_coherent. Realign arguments as appropriate.

Unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure. Signed-off-by: Libo Chen <libo.chen@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-05-11emac: Fix EMAC soft reset on 460EX/GTPetri Gynther
Fix EMAC soft reset on 460EX/GT to select the right PHY clock source before and after the soft reset. EMAC with PHY should use the clock from PHY during soft reset. EMAC without PHY should use the internal clock during soft reset. PPC460EX/GT Embedded Processor Advanced User's Manual section 28.10.1 Mode Register 0 (EMACx_MR0) states: Note: The PHY must provide a TX Clk in order to perform a soft reset of the EMAC. If none is present, select the internal clock (SDR0_ETH_CFG[EMACx_PHY_CLK] = 1). After a soft reset, select the external clock. Without the fix, 460EX/GT-based boards with RGMII PHYs attached to EMACs experience EMAC interrupt storm and system watchdog reset when issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times. The system enters endless loop of serving emac_irq() with EMACx_ISR register stuck at value 0x10000000 (Rx parity error). With the fix, the above issue is no longer observed.

2011-08-18net: fix IBM EMAC driver after rename.Tony Breeds
In commit 9aa3283595451ca093500ff0977b106e1f465586 (ehea/ibm*: Move the IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC* The conversion was incomplete so that even if the driver was added to the .config it wasn't built, but there were no errors). In this commit we also update the various defconfigs that use EMAC to use the new Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard. We do not explicitly select the Kconfig dependencies, as this would force EMAC on. Doing it in the defconfig allows more flexibility. Tested on a canyondlands board.
