c08b7b3ef6 [ARM] 4435/1: PXA: remove PXA_INTERNAL_IRQS
1. define PXA_GPIO_IRQ_BASE to be right after the internal IRQs,
   and define PXA_GPIO_IRQ_NUM to be 128 for all PXA2xx variants

2. make the code specific to the high IRQ numbers (32..64) to be
   PXA27x specific

3. add a function pxa_init_irq_high() to initialize the internal
   high IRQ chip, the invoke of this function could be moved to
   PXA27x specific initialization code

486c955118 [ARM] 4434/1: PXA: remove PXA_IRQ_SKIP
1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
   starts from zero. This makes IRQ numbering inconsistent between
   PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
   definition has the same value on both PXA25x and PXA27x.

2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
   avoids unintentional use of these macros on PXA25x

88dfe98c68 [ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()
pxa_pm_prepare() tried to validate the suspend method type.  As
noted in previous commits:
	eb9289eb20
	9c372d06ce
	e8c9c50269

the checking of the suspend type in the 'prepare' method is the
wrong place to do this; use the 'valid' method instead.  This
means that pxa_pm_prepare() can be entirely removed.

7edcb9abb5 i2c-i801: Use the internal 32-byte buffer on ICH4+
Add an ability to utilize the internal SRAM buffer on ICH4
and newer host controllers to speed up execution of block operations.

I've split the code so that it is more clear which block transaction is
performed.

First of all the host controller's type is identified. isich4 is set when
we think that the controller has the internal buffer. Then, before every
block transaction, if isich4 is set, we attempt to enable the E32B bit in
SMBAUXCTL register.

4b2643d7d9 i2c: Fix the i2c_smbus_read_i2c_block_data() prototype
Let the drivers specify how many bytes they want to read with
i2c_smbus_read_i2c_block_data(). So far, the block count was
hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense.
Many driver authors complained about this before, and I believe it's
about time to fix it. Right now, authors have to do technically stupid
things, such as individual byte reads or full-fledged I2C messaging,
to work around the problem. We do not want to encourage that.

I even found that some bus drivers (e.g. i2c-amd8111) already
implemented I2C block read the "right" way, that is, they didn't
follow the old, broken standard. The fact that it was never noticed
before just shows how little i2c_smbus_read_i2c_block_data() was used,
which isn't that surprising given how broken its prototype was so far.

There are some obvious compatiblity considerations:
* This changes the i2c_smbus_read_i2c_block_data() prototype. Users
  outside the kernel tree will notice at compilation time, and will
  have to update their code.
* User-space has access to i2c_smbus_xfer() directly using i2c-dev, so
  the changed expectations would affect tools such as i2cdump. In order
  to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA
  a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the
  old numeric value. When i2c-dev receives a transaction with the
  old value, it can convert it to the new format on the fly.
