  virtio: set pci bus master enable bit

This patch adds support for the Xilinx XPS IIC Bus Interface.

The driver uses the dynamic mode, supporting to put several
I2C messages in the FIFO to reduce the number of interrupts.

It has the same feature as ocores, it can be passed a list
of devices that will be added when the bus is probed.

The current i2c-omap driver is set up for 32-bit registers, which
corresponds to most OMAP devices.  However, OMAP730/850 based
devices use a 16-bit register size.

This change modifies the driver to perform a runtime CPU type check
to determine the register sizes, and uses a bit shift of either 1
or 2 bits to compute the proper register sizes for all registers.

The start/stop condtions are set in different places repetedly in the i2c-pnx
driver.  Beside in i2c_pnx_start and i2c_pnx_stop the start/stop bit are also
set during the transfer of a i2c message in the master_xmit/rcv calls. This is
wrong since we can't set the start/stop condition during the transaction of a
single message any way. As a matter of fact, the driver will sometimes set both
the start and the stop bits at one time. This can be easily reproduced by
sending a simple read request like e.g
struct i2c_msg msgs[] = {
{ addr, 0, 1, buf },
{ addr, I2C_M_RD, offset, buf }
};
While processing the first message the i2c_pnx_master_xmit will set both the
start_bit and the stop_bit, which will eventually confuse the slave.

Fixed by remove setting start/stop condition from the transmit routines.

As I2C interrupts must  be enabled for the MPC512x by the setup function
as well, "fsl,preserve-clocking" is handled in a slighly different way.
Also, the old settings are now reported calling dev_dbg(). For the
MPC512x the clock setup function of the MPC52xx can be re-used.
Furthermore, the Kconfig help has been updated and corrected.

LPC_SCH is selected by GPI_SCH and I2C_ISCH, even when PCI is not
enabled, but LPC_SCH depends on PCI, so make GPI_SCH and I2C_ISCH
also depend on PCI.

Those 2 selects also need to select what LPC_SCH selects,
since kconfig does not follow selects.

Use the completion interrupt generated by the device rather than
polling for conversions to complete. As a backup we still check
the status of the AUXADC if we don't get a completion, mostly for
systems that don't have the WM831x interrupt infrastructure hooked
up.

Also reduce the timeout for completion of conversions to 5ms from
the previous 10ms, the lower timeout should be sufficient.

New function twl4030_remove_script(u8 flags) takes a script type as
defined in twl.h and prevents any script already loaded in that position
from running.  This is accomplished by programming SEQ_ADD_* to 0x3f,
the END_OF_SCRIPT value, where SEQ_ADD_* is determined by flags.

facing a race condition between sleep and warm reset.

Take account of this in the gpiolib driver.

A current sink regulation status bit has also been added in revision B,

This revision also adds an interrupt on key up for the ON pin event
