[PATCH 0/8] musb patches

[Felipe Balbi]

Hi Tony,

the following are few cleanups for the usb-musb.c
file. Another patch will go through Greg getting rid
of omap_readl/omap_writel.

For ease, these patches are also available at:

git://gitorious.org/usb/usb.git for-tony

. Boot tested on RX-51
. Compile tested with all defconfigs that have USB_MUSB_SOC=y

[PATCH 6/8] arm: omap: musb: pass power to usb_musb_init

each board might have a different charge pump and
thus able to source more or less current on vbus
so let power be easily configurable.

Re: [PATCH 7/8] arm: omap: musb: pass board mode to usb_musb_init

[Tony Lindgren]

The subject and description for this too should be updated
to say it fixes the mode.

How about now ? (did the same to the board mode)

    arm: omap: musb: fix board mode by passing it to usb_musb_init
    
    each board will have a different mode which is peculiar
    to that board.

Oh one more thing: Can you please repost the series one more
time with LAKML Cc'd? We should have all the arch/arm/*omap*/
patches reviewed there too. Maybe Cc linux-usb too?

Similarly, we would need another parameter 'extvbus' which is required by
OMAP3EVM Rev >= E. This way the parameter list would keep increasing and
would look ugly.

So how about passing a "struct musb_board_data" structure completely ? It
Can be generic across the musb platforms or we can have it only for OMAP
platforms.

I suggested that off list already. We will add some void * to
musb_platform_data which would allow archs to pass whatever data
structure they want down to drivers/usb/musb/<arch>.c
