[PORT FROM R2] hsi_ffl_tty.c: using a dedicated work queue for line discipline flush work

BZ: 17676

This patch is introducing a dedicated work to prevent too big a latency on the
modem protocol driver TTY interface when used with a line discipline, such as
the n_gsm. The TTY driver implementation is relying on the system work queue
to flush what is ready to be transferred to the line discipline. But, should
this shared work queue be busy for much too long with other works, the latency
at the user land TTY interface is getting too big making the system either
less responsive or even rebooting the modem !

This patch is forcing the TTY interface to skip its internal flush work to
minimise those latencies (this is the purpose of the TTY low_latency flag).
Still, as the flush mecanism can sleep, some dedicated work queue is put in
place and the full forward TTY mechanism is managed in a work running on this
dedicated work queue (the ffl_forwarding_wq).

This patch is compatible with Linux 2.6 and Linux 3.0 and does not require the
streamlined TTY code to be changed.

usb:composite: reset next_string_id after remove configuration

BZ: 19826

next_string_id can be increase to 255 if configuration is added/removed continuously, and allocation of next_string_id will fail
if the value is 255 which means no more available string id. So reset next_string_id to 0 when configuration is removed.

[Rebase from r2]]audio: sn95031: added GPIO support for jack detection

BZ: 19775

OLD_BZ:14181
PR3.x devices have a GPIO pin which can be used to detect high impedance
headsets.

Added GPIO support in the codec driver so that whenever an insert interrupt is
received and the micbias value is out of range, it checks the GPIO pin and
reports the jack as a HEADSET if the GPIO pin says that there is a headset.

Since PR2 devices don't have this GPIO pin, they are no longer supported.

[Rebase from R2]audio: sst: sn95031: Enable PLL and VAUDA before changing volume registers

BZ: 19775

old_BZ:18716

Due to a problem with the codec, any writes made to the *VOLCTRL registers are
not reflected until the VAUDA and clocks are turned on.

Implemented a volume control function which turns on the PLLs and the VAUDA
before changing the VOLCTRL registers. It then restores the previous state back.

While VOLCTRL registers were getting updated eventually when some actual
playback started, the values read back before playback were wrong. This fixes
that issue. Volume can now be set and read using amixer for tuning purposes.

BZ: 17876 18551

1. Previously, when ALS is enabled, it will report zero before the first
interrupt occurs, this may cause incorrect behavior of LED light.  Now
ALS doesn't report any data until the first interrupt occurs.
2. In order to speed up the interrupt triggering, ADC sample integration
circle of ALS is changed to 1.

[PORT FROM R2] pn544: Adding suspend to ram support.

BZ: 11182

To be able to suspend the pn544, the driver shall guarantee that the
suspend process doesn't occurs within a read cycle. For this purpose,
a read wake lock is held when reading the first byte and released
when reading the requested data.

PN544 interrupt shall wake up the platform from suspend to ram. For
this, the interrupt shall be IRQ wake capable and shall be disabled
on PM_SUSPEND_PREPARE. This is mondatory to avoid loosing interrupts
during the suspend to ram.

Note that suspend process starts by freezing the user space tasks, so
the reader thread will be signaled and wait_event_interruptible will
return -ERESTARTSYS. The upper layer shall handle such situation by
triggering the read process again.

BZ: 12814

This patch will use udelay instead of mdelay when waiting for
SDHCI hardware to be stable. udelay can help to reduce the waiting
time when is in critical region which is protected by spinlock.

With this patch, __sdhci_set_ios only take a few microseconds to be
done.

Checking in color correction IOCTL call

BZ: 17761

This IOCTL call exposes the csc_program_DC function to allow a user
to send in a 3x3 color correction matrix to the driver.

The basics are that you have a new struct defined in psb_drm.h as follows:
struct drm_psb_csc_matrix {
    int pipe;
    int64_t matrix[9];
};

The matrix variable is define such that the 3x3 matrix will be represented
in a vector with 9 elements.
M00 = V0, M01 = V1, M02 = V2,
M10 = V3, M11 = V4, M12 = V5,
M20 = V6, M21 = V7, M22 = V8.

The pipe variable is defined as the offset to the PIPEASRC register value
as defined in psb_intel_reg.h (see the PIPEB and PIPEC definitions in that
file.  The function that does the color correction checks against PIPEB
and PIPEC values and assumes you are setting the correction to PIPEA if no
match is found.
FYI
PIPEB = 0x1
PIPEC =0x2
PIPEA has no formal definition.  I used 0x0 for my purposes.

The ioctl number is defined as
\#define DRM_IOCTL_PSB_SET_CSC DRM_IOW(DRM_PSB_SET_CSC + DRM_COMMAND_BASE, \
 struct drm_psb_csc_matrix (found in psb_drv.c)
\#define DRM_PSB_SET_CSC     0x29 (found in psb_drm.h)

Finally the actual function doing the work looks like this:

static int psb_set_csc_ioctl(struct drm_device *dev, void *data, struct drm_file *file_priv)
{
    struct drm_psb_csc_matrix *csc_matrix = data;
    csc_program_DC(dev, csc_matrix->matrix, csc_matrix->pipe);
    return 0;
}
