0014-8250_pci-add-ENODEV-code-for-Intel-EG20T-PCH.patch
8250_pci: add -ENODEV code for Intel EG20T PCH
Intel EG20T PCH has UART device which is compatible with 8250.
Currently, with general configuration, the PCH UART driver is not loaded
but 8250 standard driver is loaded.
Therefore, in case of using PCH UART driver, need to disable 8250 pci
function. However, this procedure is not best solution.
This patch, in 8250_pci, if the device is the PCH or the family IOH,
'-ENODEV' is returned.
As a result, disabling 8250-pci processing becomes unnecessary.
0015-pch_uart-MSI-support.patch

Enabling CONFIG_TRACE_IRQFLAGS ans CONFIG_PROVE_LOCKING,
kernel error messages occurs.
This patch fixes the issue.
0022-pch_dma-Fix-CTL-register-access-issue.patch
pch_dma: Fix CTL register access issue
Currently, Mode-Control register is accessed by read-modify-write.
According to DMA hardware specifications datasheet, prohibits this
method. Because this register resets to 0 by DMA HW after DMA transfer
completes. Thus, current read-modify-write processing can cause
unexpected behavior.
The datasheet says in case of writing Mode-Control register, set the
value for only target channel, the others must set '11b'.
e.g. Set DMA0=01b DMA11=10b
CTL0=33333331h
CTL2=00002333h
NOTE:
CTL0 includes DMA0~7 Mode-Control register.
CTL2 includes DMA8~11 Mode-Control register.
This patch modifies the issue.

Currently, when suspend is occurred, register im0/1 and gpio_use_sel are
not saved.
This patch modifies so that register im0/1 and gpio_use_sel are saved.
0027-pch_udc-unlock-on-allocation-failure.patch
pch_udc: unlock-on-allocation-failure
Currently, in case memory allocation fails, spin-lock is not unlocked.
This patch fixes the issue.

by I2S hardware is stopped between sound card stops.
-------------------------------------------
20110824.tar.bz2
-------------------------------------------
0001-support-for-soundcard-monaural-and-i2s-reg-config.patch
soundcard: Playback and recording of a monaural sound are attained
by adding this patch.
i2s driver: The i2s driver before applying this patch supported
the digital audio interface(DAI)
which connects a codec with I2S hardware only at the I2S format.
By applying this patch, the format of DAI can be changed.
The main difference is the followings.
Before applying this patch
Support Samplyng frequency (Fs): 16kHz, 32kHz, 48kHz
Support BCLK : 32*Fs only
Support format : i2s format only
LRCLK and BCLK : Master only

starts. This causes FIFO overrun occurs.
This patch fixes the issue by modifying FIFO tx-threshold and DMA
descriptor size like below.
| Current --> This patch
-----------------------------------------------------------
Rx-descriptor| [1~12][12]...[12] --> [12]...[12][1~12][12]
