nitpick: there is an empty line too much.

Do you really need this file?

hmmm, I wonder why you use your nxp address here, but gmail in the

Is this cast to unsigned long needed?  AFAIK IO_ADDRESS(x) has
type unsigned for x in { 0x0 ... 0xffffffff } (provided that int uses a
32 bit 2s-complement representation).  If unsigned long is really
needed, maybe put it into the IO_ADDRESS macro?

inconsistant macro naming.  The headers above don't end in _H__, only
_H.

nitpick: is i2c.h needed in the first patch?  (Ok Ok, you work for NXP :-)

Maybe make these:

	#define LPC32XX_SIC1_IRQ(x)	(32 + (x))
	#define IRQ_LPC32XX_JTAG_COMM_TX	LPC32XX_SIC1_IRQ(1)

?  Then you can use that in lpc32xx_sic1_handler instead of an
equivalent local #define.

are these two 0xf the same?  If so, you can define
LPC32XX_CLKPWR_SET_PLL_USBPDIV without hardcoding it?
