-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.

-
-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.
