2014-03-21ptp: drivers: set the number of programmable pins.Richard Cochran1-0/+1
This patch updates the many PTP Hardware Clock drivers with the newly introduced field that advertises the number of programmable pins. Some of these devices do have programmable pins, but the implementation will have to wait for follow on patches.

2014-01-16drivers/net: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. This covers everything under drivers/net except for wireless, which has been submitted separately. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S.

This is untested. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2013-06-07fec: Only pass pdev in fec_ptp_init()Fabio Estevam1-1/+2
Passing pdev in fec_ptp_init() is enough, since we can get ndev locally. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-14fec: Convert printks to netdev_<level>Joe Perches1-0/+2
Use a more current logging message style. Convert the printks where a struct net_device is available to netdev_<level>. Convert the other printks to pr_<level> and add pr_fmt where appropriate. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-13fec: Fix PHC device logFabio Estevam1-2/+0
Currently when booting a mx6 device we get the following on boot: registered PHC device on eth%d Fix it by printing the network device name only after it gets registered, so that the following can be read now: fec 2188000.ethernet eth0: registered PHC device 0 Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S.

2013-03-20fec: Fix the build as moduleFabio Estevam1-0/+3
Since commit ff43da86c69 (NET: FEC: dynamtic check DMA desc buff type) the following build error happens when CONFIG_FEC=m ERROR: "fec_ptp_init" [drivers/net/ethernet/freescale/fec.ko] undefined! ERROR: "fec_ptp_ioctl" [drivers/net/ethernet/freescale/fec.ko] undefined! ERROR: "fec_ptp_start_cyclecounter" [drivers/net/ethernet/freescale/fec.ko] undefined!

2012-11-01FEC: Add time stamping code and a PTP hardware clockFrank Li1-0/+385
This patch adds a driver for the FEC(MX6) that offers time stamping and a PTP haderware clock. Because FEC\ENET(MX6) hardware frequency adjustment is complex, we have implemented this in software by changing the multiplication factor of the timecounter.
