commit dfc50fcaad574e5c8c85cbc83eca1426b2413fa4 upstream.
Current check of phydev with IS_ERR(phydev) may make not much sense
because of_phy_connect() returns NULL on failure instead of error value.
Still for checking result of phy_connect() IS_ERR() makes perfect sense.
So let's use combined check IS_ERR_OR_NULL() that covers both cases.

The patch b1c17215d718: "stmmac: add ipq806x glue layer", leads to the
following static checker warning:
.../stmmac/dwmac-ipq806x.c:314 ipq806x_gmac_probe()
warn: double left shift '1 << (1 << gmac->id)'
The NSS_COMMON_CLK_SRC_CTRL_OFFSET macro is used once as an offset, and
once as a mask, which is a bug indeed. We'll fix it by defining the
offset as the real offset value and computing the mask from it when
required.
Tested on IPQ806x ref designs AP148 & DB149.

Commit 50649ab14982 ("stmmac: drop driver from stmmac platform code")
was a bit overzealous in removing code and dropped the MODULE_*
macro's that are still needed since stmmac_platform can be a module.
Fix this by putting the macro's remvoed in 50649ab14982 back.
This fixes the following errors when used as a module:
stmmac_platform: module license 'unspecified' taints kernel.
Disabling lock debugging due to kernel taint

Commit 803f8fc46274b ("stmmac: move driver data setting into
stmmac_dvr_probe") mistakenly set priv and not priv->dev as
driver data. This meant that the remove, resume and suspend
callbacks that fetched and tried to use this data would most
likely explode. Fix the issue by using the correct variable.

Current implementation of descriptor init procedure only takes
care about setting/clearing ownership flag in "des0"/"des1"
fields while it is perfectly possible to get unexpected bits
set because of the following factors:
[1] On driver probe underlying memory allocated with
dma_alloc_coherent() might not be zeroed and so
it will be filled with garbage.
[2] During driver operation some bits could be set by SD/MMC
controller (for example error flags etc).
And unexpected and/or randomly set flags in "des0"/"des1"
fields may lead to unpredictable behavior of GMAC DMA block.
This change addresses both items above with:
[1] Use of dma_zalloc_coherent() instead of simple
dma_alloc_coherent() to make sure allocated memory is
zeroed. That shouldn't affect performance because
this allocation only happens once on driver probe.
[2] Do explicit zeroing of both "des0" and "des1" fields
of all buffer descriptors during initialization of
DMA transfer.
And while at it fixed identation of dma_free_coherent()
counterpart as well.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

The first iteration of the dwmac-rk support did access an intermediate
clock directly below the pll selector. This was removed in a subsequent
revision, but the clock and one invocation remained. This results in
the driver trying to set the rate of a non-existent clock when the soc
and not some external source provides the phy clock for RMII phys.
So set the rate of the correct clock and remove the remaining now
completely unused definition.

stmmac DebugFS entries are currently global to the driver. As a result,
having more than one stmmac device in the system creates the following
error:
* ERROR stmmaceth, debugfs create directory failed
* stmmac_hw_setup: failed debugFS registration
This also results in being able to access the debugfs information for
the first registered device only.
This patch changes the debugfs structure to have one sub-directory per
net-device. Files under "/sys/kernel/debug/stmmaceth" will now show-up
under /sys/kernel/debug/stmmaceth/ethN/.

Currently we're getting IRQs after lots of resources are already
allocated:
* netdev
* clocks
* MDIO bus
Also HW gets initialized by the time when checking IRQs as well.
Now there's a possibility for master interrupt controller to be not
probed yet. This will lead to exit from GMAC probe routine with "-
EPROBE_DEFER" and so deferred probe will hapen later on.
But since we exited the first GMAC probe without release of all
allocated resources there could be conflicts on subsequent probes.
For example this is what happens for me:

This patch introduces run-time board detection through DMI and MAC-PHY
configuration function used by quark_default_data() during initialization. It
fills up the phy_addr for Galileo and Galileo Gen2 boards to indicate that the
Ethernet MAC controller is or is not connected to any PHY.
The implementation takes into consideration for future expansion in Quark
series boards that may have different PHY address that is linked to its MAC
controllers.
This piece of work is derived from Bryan O'Donoghue's initial work for Quark
X1000 enabling.
