From da68ccec210c45eb99e461ad31b499b4e7043c41 Mon Sep 17 00:00:00 2001 From: Hema HK Date: Mon, 28 Feb 2011 14:19:33 +0530 Subject: [PATCH] usb: musb: Remove platform context save/restore API For OMAP3 and OMAP4 for offmode and retention support, musb sysconfig is configured to force idle and standby with ENABLE_FORCE bit of OTG_FORCESTNDBY set. And on wakeup configure to no ilde/standby with resetting the ENABLE_FORCE bit. There is not need to save and restore of this register anymore so removed omap2430_save_context/omap2430_restore_context functions. and also removed otg_forcestandby member of musb_context_registers structure Signed-off-by: Hema HK Signed-off-by: Felipe Balbi --- drivers/usb/musb/musb_core.h | 4 ---- drivers/usb/musb/omap2430.c | 11 ----------- 2 files changed, 15 deletions(-) diff --git a/drivers/usb/musb/musb_core.h b/drivers/usb/musb/musb_core.h index 5216729bd4b2..5cb50f8f2907 100644 --- a/drivers/usb/musb/musb_core.h +++ b/drivers/usb/musb/musb_core.h @@ -358,10 +358,6 @@ struct musb_csr_regs { struct musb_context_registers { -#if defined(CONFIG_ARCH_OMAP2430) || defined(CONFIG_ARCH_OMAP3) || \ - defined(CONFIG_ARCH_OMAP4) - u32 otg_forcestandby; -#endif u8 power; u16 intrtxe, intrrxe; u8 intrusbe; diff --git a/drivers/usb/musb/omap2430.c b/drivers/usb/musb/omap2430.c index 64cf2431c05e..b6dcc7eaa21f 100644 --- a/drivers/usb/musb/omap2430.c +++ b/drivers/usb/musb/omap2430.c @@ -488,15 +488,6 @@ static int __exit omap2430_remove(struct platform_device *pdev) } #ifdef CONFIG_PM -static void omap2430_save_context(struct musb *musb) -{ - musb->context.otg_forcestandby = musb_readl(musb->mregs, OTG_FORCESTDBY); -} - -static void omap2430_restore_context(struct musb *musb) -{ - musb_writel(musb->mregs, OTG_FORCESTDBY, musb->context.otg_forcestandby); -} static int omap2430_suspend(struct device *dev) { @@ -505,7 +496,6 @@ static int omap2430_suspend(struct device *dev) omap2430_low_level_exit(musb); otg_set_suspend(musb->xceiv, 1); - omap2430_save_context(musb); if (!pm_runtime_suspended(dev) && dev->bus && dev->bus->pm && dev->bus->pm->runtime_suspend) @@ -524,7 +514,6 @@ static int omap2430_resume(struct device *dev) dev->bus->pm->runtime_resume(dev); omap2430_low_level_init(musb); - omap2430_restore_context(musb); otg_set_suspend(musb->xceiv, 0); return 0; -- GitLab
