a09e64fbc0 [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach
This just leaves include/asm-arm/plat-* to deal with.

be50972935 [ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

0f8469a54f [ARM] Eliminate useless includes of asm/mach-types.h
There are 43 includes of asm/mach-types.h by files that don't
reference anything from that file.  Remove these unnecessary
includes.

2e74378798 i2c-davinci: Initialize cmd_complete sooner
If an interrupt happens before an I2c master read/write,
complete is called on uninitialized structure.

5a0d5f5ffa i2c-davinci: Fix signal handling bug
If wait_for_completion_interruptible_timeout exits due
to a signal, the i2c bus was locking up.

0ab56e2067 i2c-davinci: Remove useless IVR read
Interrupts are enabled at the point where the DAVINCI_I2C_IVR_REG is read,
so unless an interrupt happened just at that moment, no interrupt would be
pending. Even though documentation implies you should do this, I see no
reason. If slave support is added, this read would cause a hard to
reproduce bug.

d868caa177 i2c-davinci: Move dev_dbg statement for more output
Previously the dev_dbg only printed if no error.
Printing also on an error is more useful

add8eda7f2 i2c: Fix platform driver hotplug/coldplug
Since 43cc71eed1, the platform
modalias is prefixed with "platform:". Add MODULE_ALIAS() to the
hotpluggable I2C platform drivers, to allow module auto loading.

[ db: add some more drivers ]

b73a9aece5 i2c-davinci: Fix lost interrupt
DAVINCI_I2C_STR_REG is a write 1 to clear register,
so don't use a read/modify/write cycle.

2caeac8104 i2c: Don't uselessly set i2c_adapter.retries
I2C adapter drivers are supposed to handle retries on nack by themselves
if they do, so there's no point in setting .retries if they don't.

As this retry mechanism is going away (at least in its current form),
clean this up now so that we don't get build failures later.
