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

this in the driver name.

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.

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 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.

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.
