MLK-11051 net: phy: mdio_bus: don't call .phy_suspendi() when netdev is NULL
In .mdio_bus_phy_may_suspend(), there check netdev is NULL to judge to set
phy to suspend status.
netdev is NULL has three cases:
- phy is not found
- phy is found, match to general phy driver
- phy is found, match to specifical phy driver
Case 1: phy is not found, cannot communicate by MDIO bus.
Case 2: phy is found:
if phy dev driver probe/bind err, netdev is not __open__ status,
mdio bus is unregistered.
if phy is detached, phy had entered suspended status.
Case 3: phy is found, phy is detached, phy had entered suspended status.
So, in here, it shouldn't set phy to suspend by calling mdio bus.
In i.MX6UL evk/arm2 board, if down the ethx interface and do suspend/resume,
system will hang. Because after ethx down all clocks are gated off, for general
phy driver, unbind the phy device, for specifical phy driver, no unbind the
device, and the original driver call mdio bus to set phy to suspend during
system suspend, so system will hang since there have mdio register access.
The patch can fix it.

A patch(set imx6qp eim_slow to 132Mh) was pushed to eliminate

Replace of_irq_to_resource() in the SECVIO module with the simpler
equivalent irq_of_parse_and_map(). Also, add error checking to
to the SECVIO and Job Ring modules. Based on upstream commit
f7578496a671a96e501f16a5104893275e32c33a.

MLK-10036 Freescale CAAM: Add support for DSM with Mega/Fast mix on
This patch allows CAAM to be enabled as a wakeup source for the
Mega/Fast mix domain. If CAAM is enabled as a wakeup source, it
will continue to be powered on across Deep Sleep Mode (DSM). This
allows CAAM to be functional after the system resumes from DSM.

MLK-9769-20 Limit AXI pipeline to a depth of one in CAAM for i.MX6 devices
i.MX6 devices have an issue wherein AXI bus transactions may not occur
in the correct order. This isn't a problem running single descriptors,
but can be if running multiple concurrent descriptors. Reworking the CAAM
driver to throttle to single requests is impractical, so this patch limits
the AXI pipeline to a depth of one (from a default of four) to preclude
this situation from occurring.
