Currently, MoCA fixed PHYs are always in link-up state, regardless of
whether the link is actually up or not.
Add code to properly detect MoCA link state changes and to reflect the
new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of
detecting MoCA link state changes.
The code works as follows:
1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP
or UMAC_IRQ_LINK_DOWN interrupt.
2. Link up/down interrupt is processed in bcmgenet_irq_task(), which
calls phy_mac_interrupt().
3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks
the PHY state machine.
4. PHY state machine proceeds to read the fixed PHY link status
register.
5. When the fixed PHY link status register is being read, the new
function bcmgenet_fixed_phy_link_update() gets called. It copies
the fixed PHY phydev->link value to the fixed PHY status->link.
6. PHY state machine receives the new link state of the fixed PHY.
7. MoCA fixed PHY link state now correctly reflects the real MoCA
hardware link state.

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.

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

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)

This driver is 64 bit only, and so this driver and device are ready
for 2038. This patch changes the driver to the new PHC and also
carries the timespec64 parameter on out to the gxio_mpipe_get-
set_timestamp functions, making explicit the fact that the tv_sec
field is 64 bits wide.
