ASoC: Fixes for v3.14

Browse Source 
A few things here:
  - Avoid memory leaks in error cases with DPCM, this code has never been
    that well tested in mainline due to the lack of mainline drivers but
    we now have one queued for the merge window!
  - Fix the N810 audio driver to load when booted with DT since the
    platform was converted to DT during the merge window.
  - Fixes for initialisation of some MFD drivers that are probably unused
    in mainline

A successful call allocates ONE interrupt to the device, regardless
of how many MSIs the device supports. The device is switched from
pin-based interrupt mode to MSI mode. The dev->irq number is changed
to a new number which represents the message signaled interrupt;
consequently, this function should be called before the driver calls
request_irq(), because an MSI is delivered via a vector that is
different from the vector of a pin-based interrupt.

If data space is exhausted the pool will either error or queue IO
according to the configuration (see: error_if_no_space). If metadata
space is exhausted or a metadata operation fails: the pool will error IO
until the pool is taken offline and repair is performed to 1) fix any
potential inconsistencies and 2) clear the flag that imposes repair.
Once the pool's metadata device is repaired it may be resized, which
will allow the pool to return to normal operation. Note that if a pool
is flagged as needing repair, the pool's data and metadata devices
cannot be resized until repair is performed. It should also be noted
that when the pool's metadata space is exhausted the current metadata
transaction is aborted. Given that the pool will cache IO whose
completion may have already been acknowledged to upper IO layers
(e.g. filesystem) it is strongly suggested that consistency checks
(e.g. fsck) be performed on those layers when repair of the pool is
required.

Required properties:

"st,stid127-dwmac".
- reg : Offset of the glue configuration register map in system
configuration regmap pointed by st,syscon property and size.
- reg-names : Should be "sti-ethconf".
- st,syscon : Should be phandle to system configuration node which
encompases this glue registers.
- st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
wired up in from different sources. One via TXCLK pin and other via CLK_125
pin. This wiring is totally board dependent. However the retiming glue
logic should be configured accordingly. Possible values for this property
"txclk" - if 125Mhz clock is wired up via txclk line.
"clk_125" - if 125Mhz clock is wired up via clk_125 line.
This property is only valid for Giga bit setup( GMII, RGMII), and it is
un-used for non-giga bit (MII and RMII) setups. Also note that internal
clockgen can not generate stable 125Mhz clock.
- st,ext-phyclk: This boolean property indicates who is generating the clock
for tx and rx. This property is only valid for RMII case where the clock can
be generated from the MAC or PHY.

The 3Com Etherlink Plus (3c505) driver.
This driver now uses DMA. There is currently no support for PIO operation.
The default DMA channel is 6; this is _not_ autoprobed, so you must
make sure you configure it correctly. If loading the driver as a
module, you can do this with "modprobe 3c505 dma=n". If the driver is
linked statically into the kernel, you must either use an "ether="
statement on the command line, or change the definition of ELP_DMA in 3c505.h.
The driver will warn you if it has to fall back on the compiled in
default DMA channel.
If no base address is given at boot time, the driver will autoprobe
ports 0x300, 0x280 and 0x310 (in that order). If no IRQ is given, the driver
will try to probe for it.
The driver can be used as a loadable module.
Theoretically, one instance of the driver can now run multiple cards,
in the standard way (when loading a module, say "modprobe 3c505
io=0x300,0x340 irq=10,11 dma=6,7" or whatever). I have not tested
this, though.
The driver may now support revision 2 hardware; the dependency on
being able to read the host control register has been removed. This
is also untested, since I don't have a suitable card.
Known problems:
I still see "DMA upload timed out" messages from time to time. These
seem to be fairly non-fatal though.
The card is old and slow.
To do:
Improve probe/setup code
Test multicast and promiscuous operation
Authors:
The driver is mainly written by Craig Southeren, email
<craigs@ineluki.apana.org.au>.
