2016-08-08net/fsl: use of_property_read_boolJulia Lawall1-5/+2
Use of_property_read_bool to check for the existence of a property. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e1,e2,x; @@ - if (of_get_property(e1,e2,NULL)) - x = true; - else - x = false; + x = of_property_read_bool(e1,e2); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-17net/fsl: constify of_device_id arrayFabian Frederick1-1/+1
of_device_id is always used as const. (See driver.of_match_table and open firmware functions) Signed-off-by: Fabian Frederick <fabf@skynet.be> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-16net/fsl: modify xgmac_mdio for little endian SoCsShaohui Xie1-28/+68
MDIO controller on little endian Socs, e.g. ls2085a is similar to the controller on big endian Socs, but the MDIO access is little endian, we use I/O accessor function to handle endianness, so the driver can run on little endian Socs. A property "little-endian" is used in DTS to indicate the MDIO is little endian, if driver probes the property, driver will access MDIO in little endian, otherwise, driver works in big endian by default.

2015-03-16net/fsl: fix a bug in xgmac_mdioShaohui Xie1-1/+1
There is a bug in xgmac_wait_until_done() which mdio_stat should be used instead of mdio_data when checking if busy bit is cleared. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-25net/fsl: Replace spin_event_timeout() with arch independent in xgmac_mdioShaohui Xie1-8/+16
spin_event_timeout() is PPC dependent, use an arch independent equivalent instead. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-25net/fsl: drop in_be32() & out_be32() in xgmac_mdioShaohui Xie1-14/+14

2015-01-13net/fsl: fix a bug in xgmac_mdioShaohui Xie1-1/+1
There is a bug in xgmac_mdio_read when clear the bit MDIO_STAT_ENC, which '&' is missed in 'mdio_stat &= ~MDIO_STAT_ENC'. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-06net/fsl: Add mEMAC MDIO support to XGMAC MDIOAndy Fleming1-11/+53
The Freescale mEMAC supports operating at 10/100/1000/10G, and its associated MDIO controller is likewise capable of operating both Clause 22 and Clause 45 MDIO buses. It is nearly identical to the MDIO controller on the XGMAC, so we just modify that driver.

2015-01-02net/fsl: remove hardcoded clock setting from xgmac_mdioShaohui Xie1-14/+0
There is no need to set the clock speed in read/write which will be performed unnecessarily for each mdio access. Init it during probe is enough. Also, the hardcoded clock value is not a proper way for all SoCs. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-02net/fsl: remove irq assignment from xgmac_mdioShaohui Xie1-2/+1
Which is wrong and not used, so no extra space needed by mdiobus_alloc_size(), use mdiobus_alloc() instead. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-02net/fsl: remove reset from xgmac_mdioShaohui Xie1-19/+0
Since the reset is just clock setting, individual mdio reset is not available. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-05-25net: ethernet: use platform_{get,set}_drvdata()Jingoo Han1-2/+2
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. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.

2012-12-03net/freescale: remove __dev* attributesBill Pemberton1-2/+2
