ASoC: Updates for v3.19
Lots and lots of changes this time around, the usual set of driver
updates and a huge bulk of cleanups from Lars-Peter. Probably the most
interesting thing for most users is the Intel driver updates which will
(with some more machine integration work) enable support for newer x86
laptops.
- Conversion of AC'97 drivers to use regmap, bringing us closer to the
removal of the ASoC level I/O code.
- Clean up a lot of old drivers that were open coding things that have
subsequently been implemented in the core.
- Some DAPM performance improvements.
- Removal of the now seldom used CODEC mutex.
- Lots of updates for the newer Intel SoC support, including support
for the DSP and some Cherrytrail and Braswell machine drivers.
- Support for Samsung boards using rt5631 as the CODEC.
- Removal of the obsolete AFEB9260 machine driver.
- Driver support for the TI TS3A227E headset driver used in some
Chrombeooks.

If the current transfer control descriptor (TCD) was not yet started,
the address will be the same as the initial address. Hence test if the
current address is less than or equal to the start address of each TCD.

Otherwise the MST resume paths can hit DPMS paths
which hit state checker paths, which hit WARN_ON,
because the state checker is inconsistent with the
hw.
This fixes a bunch of WARN_ON's on resume after

Handle up to 8 block layer requests per HW request. These requests
can be processed in parallel on the device leading to better
throughput (and less interrupts). The overhead for additional
requests is small since we don't blindly allocate new aidaws but
try to use what's left of the previous one.

AOBs (the structure describing the HW request) need to be 4K
aligned but very little of that page is actually used. With
this patch we place aidaws at the end of the AOB page and only
allocate a separate page for aidaws when we have to (lists of
aidaws must not cross page boundaries).

Instead of having a local hack taking care of sending the tuning

Instead of having a local function taking care of sending the tuning
command, let's use the common mmc_send_tuning() API provided by the mmc
core. In this way the request will be handled as any other request by
sdhci core.
As an effect of this change, the pm_runtime_get_sync() call at
esdhc_prepare_tuning() isn't needed any more.
This patch will also introduce another change in behavior, since before
the response pattern to the tuning command wasn't verified by
sdhci-esdhc-imx. The mmc_send_tuning() does that.

The handling of can error states is different between platforms.
This is an attempt to correct that problem.
I've moved this handling into a generic function for changing the
error state. This ensures that error state changes are handled
the same way everywhere (where this function is used).
This new mechanism also adds reverse state transitioning in error
frames, i.e. the user will be notified through the socket interface
when the state goes down.

Several can modules in drivers/net/can use a banner[] variable at the
top which defines a string that is used once during init. This string
is also embedded with KERN_INFO which makes it printk() specific.
Improve the code by eliminating the banner[] variable and moving the
string to where it is printed. Then switch from printk(KERN_INFO to
pr_info() for the lines that were changed.
This patch is similar to [1] which was applied to net/can.
