* [PATCH 2/5] ARM: EXYNOS4: Add support clock for EXYNOS4212

This patch splits EXYNOS4 clock code to EXYNOS4 common,
EXYNOS4210 and EXYNOS4212 for supporting new EXYNOS4212
SoC with one kernel image. Of course, this patch adds
some clock codes for EXYNOS4212 SoC.

@ 2011-08-24 13:25 ` Kukjin Kim

From: Kukjin Kim @ 2011-08-24 13:25 UTC (permalink / raw)
To: linux-arm-kernel
This patch splits EXYNOS4 clock code to EXYNOS4 common,
EXYNOS4210 and EXYNOS4212 for supporting new EXYNOS4212
SoC with one kernel image. Of course, this patch adds
some clock codes for EXYNOS4212 SoC.

From: Kukjin Kim @ 2011-08-24 13:25 UTC (permalink / raw)
To: linux-arm-kernel, linux-samsung-soc; +Cc: ben-linux, Jonghwan Choi, Kukjin Kim
From: Jonghwan Choi <jhbird.choi@samsung.com>
This patch moves regarding clock stuff of PM into clock
file to support PM on EXYNOS4210 and EXYNOS4212 with one
single kernel image. Because some clock registers are
different on each SoCs.

From: Kukjin Kim @ 2011-08-24 13:25 UTC (permalink / raw)
To: linux-arm-kernel
From: Jonghwan Choi <jhbird.choi@samsung.com>
This patch moves regarding clock stuff of PM into clock
file to support PM on EXYNOS4210 and EXYNOS4212 with one
single kernel image. Because some clock registers are
different on each SoCs.

Hello,
Is there any reason to have the following two
SAVE_ITEM(S5P_CLKSRC_IMAGE),
SAVE_ITEM(S5P_CLKDIV_IMAGE
defined at both clock-exynos4210.c and clock-exynos4212.c, not defined
at clock.c once?
Also, consider using CONFIG_PM_SLEEP rather than CONFIG_PM for
suspend/resume ops.
Cheers!

Yes, I know. I just wanted to keep in mind there is a different
value(CLKGATE_IP_IMAGE) in regarding IMAGE clocks on each SoCs, and I think
need it now. Anyway thanks for your pointing out.

(Cc'ed Rafael)
Well, even though CONFIG_PM_SLEEP is used in regarding syscore_ops, in this
case, using CONFIG_PM looks better.
If ARCH_SUSPEND_POSSIBLE will be selected, then CONFIG_SUSPEND is selected
and CONFIG_PM_SLEEP is selected in kernel/power/Kconfig and of course,
ARCH_SUSPEND_POSSIBLE is selected in arch/arm/Kconfig. However above
everything depends on CONFIG_PM. So I think to use CONFIG_PM is more
reasonable. In addition, it is more popular in other mainline codes now.
Hi Rafael,
How do you think about this?
Its original code is below.
---
#ifdef CONFIG_PM
static int exynos4210_clock_suspend(void)
{
s3c_pm_do_save(exynos4210_clock_save,
ARRAY_SIZE(exynos4210_clock_save));
return 0;
}
static void exynos4210_clock_resume(void)
{
s3c_pm_do_restore_core(exynos4210_clock_save,
ARRAY_SIZE(exynos4210_clock_save));
}
#else
#define exynos4210_clock_suspend NULL
#define exynos4210_clock_resume NULL
#endif
struct syscore_ops exynos4210_clock_syscore_ops = {
.suspend = exynos4210_clock_suspend,
.resume = exynos4210_clock_resume,
};
---
Thanks.
Best regards,
Kgene.

Yes, I know. I just wanted to keep in mind there is a different
value(CLKGATE_IP_IMAGE) in regarding IMAGE clocks on each SoCs, and I think
need it now. Anyway thanks for your pointing out.

(Cc'ed Rafael)
Well, even though CONFIG_PM_SLEEP is used in regarding syscore_ops, in this
case, using CONFIG_PM looks better.
If ARCH_SUSPEND_POSSIBLE will be selected, then CONFIG_SUSPEND is selected
and CONFIG_PM_SLEEP is selected in kernel/power/Kconfig and of course,
ARCH_SUSPEND_POSSIBLE is selected in arch/arm/Kconfig. However above
everything depends on CONFIG_PM. So I think to use CONFIG_PM is more
reasonable. In addition, it is more popular in other mainline codes now.
Hi Rafael,
How do you think about this?
Its original code is below.
---
#ifdef CONFIG_PM
static int exynos4210_clock_suspend(void)
{
s3c_pm_do_save(exynos4210_clock_save,
ARRAY_SIZE(exynos4210_clock_save));
return 0;
}
static void exynos4210_clock_resume(void)
{
s3c_pm_do_restore_core(exynos4210_clock_save,
ARRAY_SIZE(exynos4210_clock_save));
}
#else
#define exynos4210_clock_suspend NULL
#define exynos4210_clock_resume NULL
#endif
struct syscore_ops exynos4210_clock_syscore_ops = {
.suspend = exynos4210_clock_suspend,
.resume = exynos4210_clock_resume,
};
---
Thanks.
Best regards,
Kgene.

If you make syscore_ops depend on CONFIG_PM, they will be built but not
used when CONFIG_PM_RUNTIME is set and CONFIG_PM_SLEEP is unset. If you
think that's acceptable, I guess you can do it (although you may get a
few "defined but not used" warnings in that case, which don't look nice).

Rafael

Hmm...ok, I understand you mean CONFIG_PM_SLEEP is better in this case to
reduce useless warnings. Will use CONFIG_PM_SLEEP.

This patch adds mach-smdk4212.c to support SMDK4212 board.
Now it can support HSMMCs, I2Cs, RTC, WDT and Keypad. Other
features will be supported next time.
