I have been looking at the pandaboard patch in the series above and I do 
have a question. Among other things the patch adds these dt entries.

+			0x108 0x118	/* sdmmc5_clk.sdmmc5_clk INPUT_PULLUP | MODE0 */
+			0x10a 0x118	/* sdmmc5_cmd.sdmmc5_cmd INPUT_PULLUP | MODE0 */

If I look at the similar names in the deceased board-omap4panda.c:

board-omap4panda.c:	OMAP4_MUX(SDMMC5_CMD, OMAP_MUX_MODE0 | 
OMAP_PIN_INPUT_PULLUP),
board-omap4panda.c:	OMAP4_MUX(SDMMC5_CLK, OMAP_MUX_MODE0 | 
OMAP_PIN_INPUT_PULLUP),

and in mux44xx.h:

mux44xx.h:#define OMAP4_CTRL_MODULE_PAD_SDMMC5_CLK_OFFSET	0x0148
mux44xx.h:#define OMAP4_CTRL_MODULE_PAD_SDMMC5_CMD_OFFSET	0x014a

So how did 0x0148 get 0x0108 in DT and 0x014a get 0x010a. There is 
probably an explanation to it and it would help my understanding to know 
where this difference comes from. Hope you can help me out here.

Below are the definitions that I need to move into a dts.

Arend

	/* MMC2 Mux for extension board */
	/* MMC2 CMD */
	OMAP4_MUX(GPMC_NWE, OMAP_MUX_MODE1 | OMAP_PIN_INPUT_PULLUP),
	/* MMC2 CLK */
	OMAP4_MUX(GPMC_NOE, OMAP_MUX_MODE1 | OMAP_PIN_INPUT_PULLUP),
	/* MMC2 DAT 0-7 */
	OMAP4_MUX(GPMC_AD0, OMAP_MUX_MODE1 | OMAP_PIN_INPUT_PULLUP),
	OMAP4_MUX(GPMC_AD1, OMAP_MUX_MODE1 | OMAP_PIN_INPUT_PULLUP),
	OMAP4_MUX(GPMC_AD2, OMAP_MUX_MODE1 | OMAP_PIN_INPUT_PULLUP),
	OMAP4_MUX(GPMC_AD3, OMAP_MUX_MODE1 | OMAP_PIN_INPUT_PULLUP),
