Subject: [PATCH 09/32] MIPS: JZ4740: Fix i2c driver name.
The i2c driver is generic to all JZ47XX based SoCs not only the JZ4740. Reflect
this in the driver name.

Subject: [PATCH 11/32] 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 06/28] 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 09/28] /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.

From 27ff621cd9a5347efda4be502abbef13a99146ce Mon Sep 17 00:00:00 2001
From: Maarten ter Huurne <maarten@treewalker.org>
Date: Sun, 29 Aug 2010 08:11:00 +0200
Subject: [PATCH 11/28] MIPS: JZ4740: Added setting of PLL rate and main
dividers.
This functionality makes a cpufreq driver possible.
Squashed version of the development done in the jz-2.6.39 branch.

Subject: [PATCH 13/28] 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 14/28] 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 15/28] ASoC: JZ4740: Replaced comma operators with
semicolons.
They were harmless but also unnecessary, probably a leftover from earlier code.

Subject: [PATCH 16/28] 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.
