As a convenience I have been picking up Renesas clocksource patches and passing them on to Daniel. I'm happy to keep doing this. And I'm happy to go the next step and add some entries to MAINTAINERS if that is useful to others. As I mentioned above I have queued these up (though not yet pushed them as I got bogged down yesterday afternoon). But if you would prefer Daniel to take them directly then please use the following: Patches 01 - 03: Acked-by: Simon Horman > > > > --- > > > > > > drivers/clocksource/sh_cmt.c | 20 ++++++++++++++++---- > > > 1 file changed, 16 insertions(+), 4 deletions(-) > > > > > > diff --git a/drivers/clocksource/sh_cmt.c b/drivers/clocksource/sh_cmt.c > > > index 0965e98..940341a 100644 > > > --- a/drivers/clocksource/sh_cmt.c > > > +++ b/drivers/clocksource/sh_cmt.c > > > @@ -634,12 +634,18 @@ static int sh_cmt_clock_event_next(unsigned long > > > delta,> > > > static void sh_cmt_clock_event_suspend(struct clock_event_device *ced) > > > { > > > - pm_genpd_syscore_poweroff(&ced_to_sh_cmt(ced)->pdev->dev); > > > + struct sh_cmt_priv *p = ced_to_sh_cmt(ced); > > > + > > > + pm_genpd_syscore_poweroff(&p->pdev->dev); > > > + clk_unprepare(p->clk); > > > } > > > > > > static void sh_cmt_clock_event_resume(struct clock_event_device *ced) > > > { > > > - pm_genpd_syscore_poweron(&ced_to_sh_cmt(ced)->pdev->dev); > > > + struct sh_cmt_priv *p = ced_to_sh_cmt(ced); > > > + > > > + clk_prepare(p->clk); > > > + pm_genpd_syscore_poweron(&p->pdev->dev); > > > } > > > > > > static void sh_cmt_register_clockevent(struct sh_cmt_priv *p, > > > > > > @@ -737,6 +743,10 @@ static int sh_cmt_setup(struct sh_cmt_priv *p, struct > > > platform_device *pdev)> > > > goto err2; > > > } > > > > > > + ret = clk_prepare(p->clk); > > > + if (ret < 0) > > > + goto err3; > > > + > > > if (res2 && (resource_size(res2) == 4)) { > > > /* assume both CMSTR and CMCSR to be 32-bit */ > > > p->read_control = sh_cmt_read32; > > > @@ -773,19 +783,21 @@ static int sh_cmt_setup(struct sh_cmt_priv *p, > > > struct platform_device *pdev)> > > > cfg->clocksource_rating); > > > if (ret) { > > > dev_err(&p->pdev->dev, "registration failed\n"); > > > - goto err3; > > > + goto err4; > > > } > > > p->cs_enabled = false; > > > > > > ret = setup_irq(irq, &p->irqaction); > > > if (ret) { > > > dev_err(&p->pdev->dev, "failed to request irq %d\n", irq); > > > - goto err3; > > > + goto err4; > > > } > > > > > > platform_set_drvdata(pdev, p); > > > > > > return 0; > > > > > > +err4: > > > + clk_unprepare(p->clk); > > > err3: > > > clk_put(p->clk); > > > err2: > -- > Regards, > > Laurent Pinchart > > -- > To unsubscribe from this list: send the line "unsubscribe linux-sh" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
