From: Magnus Damm <[email protected]> This patch reworks platform driver power management code for musb from legacy callbacks to dev_pm_ops.
The callbacks are converted for CONFIG_SUSPEND like this: suspend() -> suspend() resume_early() -> resume_noirq() Signed-off-by: Magnus Damm <[email protected]> --- Untested but compiles fine. drivers/i2c/busses/i2c-pxa.c | 25 +++++++++++++++++-------- 1 file changed, 17 insertions(+), 8 deletions(-) --- 0001/drivers/usb/musb/musb_core.c +++ work/drivers/usb/musb/musb_core.c 2009-06-01 15:27:12.000000000 +0900 @@ -2168,8 +2168,9 @@ static int __devexit musb_remove(struct #ifdef CONFIG_PM -static int musb_suspend(struct platform_device *pdev, pm_message_t message) +static int musb_suspend(struct device *dev) { + struct platform_device *pdev = to_platform_device(dev); unsigned long flags; struct musb *musb = dev_to_musb(&pdev->dev); @@ -2196,8 +2197,9 @@ static int musb_suspend(struct platform_ return 0; } -static int musb_resume_early(struct platform_device *pdev) +static int musb_resume_noirq(struct device *dev) { + struct platform_device *pdev = to_platform_device(dev); struct musb *musb = dev_to_musb(&pdev->dev); if (!musb->clock) @@ -2215,9 +2217,14 @@ static int musb_resume_early(struct plat return 0; } +static struct dev_pm_ops musb_dev_pm_ops = { + .suspend = musb_suspend, + .resume_noirq = musb_resume_noirq, +}; + +#define MUSB_DEV_PM_OPS (&musb_dev_pm_ops) #else -#define musb_suspend NULL -#define musb_resume_early NULL +#define MUSB_DEV_PM_OPS NULL #endif static struct platform_driver musb_driver = { @@ -2225,11 +2232,10 @@ static struct platform_driver musb_drive .name = (char *)musb_driver_name, .bus = &platform_bus_type, .owner = THIS_MODULE, + .pm = MUSB_DEV_PM_OPS, }, .remove = __devexit_p(musb_remove), .shutdown = musb_shutdown, - .suspend = musb_suspend, - .resume_early = musb_resume_early, }; /*-------------------------------------------------------------------------*/ -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
