Linus Torvalds c43a5eb269 This is the 2nd MFD pull request for 3.13
It only contains one fix for the rtsx_pcr driver. Without it we see a
 kernel panic on some machines, when resuming from suspend to RAM.

Krzysztof Kozlowski 3e1e4a5f3a mfd/rtc: s5m: fix register updating by adding regmap for RTC
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.

On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC.  This could be observed in various hangs,
e.g.  in infinite loop during waiting for UDR field change.

On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.

Thomas Gleixner 73beb63d29 mfd: rtsx_pcr: Disable interrupts before cancelling delayed works
This fixes a kernel panic when resuming from suspend to RAM.
Without this fix an interrupt hits after the delayed work is canceled
and thus requeues it. So we end up freeing an armed timer.

Linus Torvalds db0b2d0116 For the 3.13 merge window we have a couple of new drivers for the AMS
AS3722 PMIC and for STMicroelectronics STw481x PMIC.
 
 Although this is a smaller update than usual, we also have:
 
 - Device tree support for the max77693 driver.
 
 - linux/of.h inclusion for all DT compatible MFD drivers, to avoid build
   breakage in the future.
 
 - Support for Intel Wildcat Point-LP PCH through the lpc_ich driver.
 
 - A small arizona update for new wm5110 DSP registers and a few fixes.
 
 - A small palmas update as well, including an of_device table addition
   and a few minor fixes.
 
 - Two small mfd-core changes, one including a memory leak fix for when
   mfd_add_device() fails.
 
 - Our usual round of minor cleanups and janitorial fixes.

Linus Torvalds eeab517b68 sound updates for 3.13-rc1
There are no too intrusive changes in this update batch.  The biggest
 LOC is found in the new DICE driver, and other small changes are
 scattered over the whole sound subtree (which is a common pattern).
 
 Below are highlights:
 
 - ALSA core:
   * Memory allocation support with genpool
   * Fix blocking in drain ioctl of compress_offload
 
 - HD-audio:
   * Improved AMD HDMI supports
   * Intel HDMI detection improvements
   * thinkpad_acpi mute-key integration
   * New PCI ID, New ALC255,285,293 codecs, CX20952
 
 - USB-audio:
   * New buffer size management
   * Clean up endpoint handling codes
 
 - ASoC:
   * Further work on the dmaengine helpers, including support for
     configuring the parameters for DMA by reading the capabilities of
     the DMA controller which removes some guesswork and magic numbers
     from drivers.
   * A refresh of the documentation.
   * Conversions of many drivers to direct regmap API usage in order to
     allow the ASoC level register I/O code to be removed, this will
     hopefully be completed by v3.14.
   * Support for using async register I/O in DAPM, reducing the time
     taken to implement power transitions on systems that support it.
 
 - Fireiwre: DICE driver
 
 - Lots of small fixes for bugs reported by Coverity

Linus Torvalds c6d65bf246 regulator: Updates for v3.13
Lots of driver updates here plus some nice new core features, the main
 one being the first:
 
  - Enable support for providing a dummy regulator when we know that one
    must exist for the device to be functional.  This makes it much
    easier to add regulator support to drivers since we don't require
    that the machine integration for all systems using the device be
    updated to provide regulators.
  - Substantial reduction in the amount of busy waiting done while
    waiting for enables to complete.
  - Allow MFDs to distribute regulator supplies to child devices so we
    don't have to expose the internal structure of MFDs outside of the
    driver.
  - Managed registeration for regulators.

Geert Uytterhoeven 0b208e41ac mfd: Fix memory leak in mfd_add_devices()
If the first call to mfd_add_device() fails, no child devices have been
registered to the parent yet, and thus mfd_remove_devices() won't find
anything to remove nor free.
Hence the previously allocated array of atomic_t objects will leak.

Free the array instead of calling mfd_remove_devices() on failure during
the first loop iteration to fix this.

Geert Uytterhoeven 03e361b25e mfd: Stop setting refcounting pointers in original mfd_cell arrays
Commit 1e29af62f2 ("mfd: Add refcounting
support to mfd_cells") had to drop the "const" keyword on the "cell"
parameter of mfd_add_devices(), as it added the refcounting pointers
to the objects of the passed mfd_cell array itself.

However, the mfd core code operates on copies of the mfd_cell objects,
so there's no need to modify the originally passed objects.

Hence, move the setting of the refcounting pointers from mfd_add_devices()
to mfd_platform_add_cell(), where the copy of the mfd_cell objects is made.
mfd_clone_cell() can just pass (a copy of) the original usage_count
pointer.

This allows to make the "cell" parameter of mfd_add_devices() "const"
again, and avoids future race conditions when registering multiple
instances of the same device in parallel.
