The i2c driver is generic to all JZ47XX based SoCs not only the JZ4740. Reflect

Subject: [PATCH 14/23] input: Add touchscreen driver for the JZ4740 SoC
This patch adds a touchscreen driver for the Ingenic JZ4740 SoC.
The touchscreen controller is part of the ADC unit and thus this driver is a mfd
cell from the jz4740-adc driver.

Subject: [PATCH 22/23] MIPS: JZ4740: Set nand ecc offsets for the qi_lb60 board
Now that the mtd core supports more then 64 ecc bytes we can use it instead of
some a custom hack in the jz4740 nand driver.
This patches sets the ecc pos fields of the ecc_layout of the qi_lb60 board.

Subject: [PATCH 06/21] MTD: NAND: JZ4740: Multi-bank support with
autodetection
The platform data can now specify which external memory banks to probe
for NAND chips, and in which order. Banks that contain a NAND are used
and the other banks are freed.
Squashed version of development done in jz-2.6.38 branch.
Original patch by Lars-Peter Clausen with some bug fixes from me.
Thanks to Paul Cercueil for the initial autodetection patch.

Subject: [PATCH 09/21] /dev/mem: Add kernel config option to omit this
device.
Omitting this device prevents software from accessing the hardware directly, which can cause trouble if the kernel accesses the same hardware.
It also saves some space on embedded systems.

Subject: [PATCH 13/21] MMC: JZ4740: Added support for CPU frequency changing.
The MSC device clock is stopped before the frequency change.
After the change a new divider is computed and the clock is restarted.
Also the frequency change is postponed if an I/O operation is in progress.

Subject: [PATCH 14/21] MIPS: JZ4740: reset: Initialize hibernate wakeup
counters.
In hibernation mode only the wakeup logic and the RTC are left running,
so this is what users perceive as power down.
If the counters are not initialized, the corresponding pin (typically
connected to the power button) has to be asserted for two seconds
before the device wakes up. Most users expect a shorter wakeup time.
I took the timing values of 100 ms and 60 ms from BouKiCHi's patch for
the Dingoo A320 kernel.

Subject: [PATCH 16/21] ASoC: JZ4740: Support buffer size that is not a
multiple of period size.
This fixes glitches triggered by libao, which sets time-based intervals
instead of byte-based intervals like SDL does.
Thanks to Paul Cercueil for figuring out that the buffer size was causing
the glitches and to Lars Clausen for helping me write the fix.
