2015-03-31net/macb: add the user i/o to ethtool register dumpNicolas Ferre2-2/+2
User i/o register EMAC_USRIO or GMAC_UR can be found on both macb and gem flavors of the peripheral. By using the proper accessor, we can add it to the register dump feature of ethtool. Increment the version of this API so it can be noticed from user space. Signed-off-by: Nicolas Ferre <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2015-03-31net/macb: fix probe sequence to setup clocks earlierNicolas Ferre2-67/+104
As accessing the peripheral registers need the clocks to be set, we have to enable them as soon as possible. Their configuration depend on the type of device used and determined by the DT compatible string. That lead to add another initialization function in the DT configuration structure. As the device private structure length depend on an information read in the registers, we have to store the clock pointers in temporary variables before feeding the structure fields.

2015-03-31net/macb: fix capabilities configurationNicolas Ferre1-18/+18
Capabilities configuration by macb_configure_caps() was moved far too late by 421d9df0628b (net/macb: merge at91_ether driver into macb driver) which would lead to badly configured hardware. So, move this function to early probe and modify its prototype to re-gain its original behavior. DT data retrieval is also moved to simplify the probe code flow.

2015-03-31net/macb: only probe queues once and use stored valuesNicolas Ferre2-4/+4
When merging at91_ether and macb driver during 421d9df0628b (net/macb: merge at91_ether driver into macb driver) the probe function has been split. The code dealing with initialization of queues is now moved in macb_init() which needs information computed in the parent macb_probe() function. So, add the queue_mask information to the private structure and use it when needed in macb_init().

Fixed two warnings in e1000e and igb, when switching to timespec64 some printf formats started to not match. In theses cases actually the new type is __kernel_time_t which is __kernel_long_t which unfortunately can be either "long" or "long long". So to solve this I cases the arguments to "long long". -DaveM Richard Cochran says: ==================== ptp: get ready for 2038 This series converts the core driver methods of the PTP Hardware Clock (PHC) subsystem to use the 64 bit version of the timespec structure, making the core API ready for the year 2038. In addition, I reviewed how each driver and device represents the time value at the hardware register level. Most of the drivers are ready, but a few will need some work before the year 2038, as shown: Patch Driver ------------------------------------------------ 12 drivers/net/ethernet/intel/igb/igb_ptp.c 15 ? drivers/net/ethernet/sfc/ptp.c 16 drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c The commit log messages document how each driver is ready or why it is not ready. For patch 15, I could not easily find out the hardware representation of the time value, and so the SFC maintainers will have to review their low level code in order to resolve any remaining issues. * ChangeLog ** V3 - dp83640: use timespec64 throughout per Arnd's suggestion - tilegx: use timespec64 throughout per Chris' suggestion - add Jeff's acked-bys ** V2 - use the new methods in the posix clock code right away (patch #3) ==================== Signed-off-by: David S.

2015-03-29net: fec: setup right value for mdio hold timeUwe Kleine-König1-3/+27
The FEC modules used on i.MX28 and newer have a register to tune the MDIO output hold time that should be at least 10 ns. Up to now this value was not explicitly set and so resulted in less hold time if the fec clock was faster than 100 MHz. This was noticed on an i.MX28 machine that uses an input clock of ~150 Mhz which resulted in unreliable communication with a Marvell switch.

This is resolved by delaying the releasing of resources until we receive acknowledgment from the PF driver that the rings have indeed been stopped.
