[PATCH 09/27] clk: samsung: exynos3250: Add clocks using common clock framework

[Chanwoo Choi]

From: Tomasz Figa <t.figa@samsung.com>

This patch add new the clock drvier of Exynos3250 SoC based on Cortex-A7
using common clock framework. The CMU (Clock Management Unit) of Exynos3250
control PLLs(Phase Locked Loops) and generate system clocks for CPU, buses,
and function clocks for individual IPs.

The CMU of Exynos3250 includes following clock doamins:
- CPU block for Cortex-A7 MPCore processor
- LEFTBUS/RIGHTBUS block
- TOP block for G3D/MFC/LCD0/ISP/CAM/FSYS/MFC/PERIL/PERIR

[PATCH 09/27] clk: samsung: exynos3250: Add clocks using common clock framework

[Chanwoo Choi]

From: Tomasz Figa <t.figa@samsung.com>

This patch add new the clock drvier of Exynos3250 SoC based on Cortex-A7
using common clock framework. The CMU (Clock Management Unit) of Exynos3250
control PLLs(Phase Locked Loops) and generate system clocks for CPU, buses,
and function clocks for individual IPs.

The CMU of Exynos3250 includes following clock doamins:
- CPU block for Cortex-A7 MPCore processor
- LEFTBUS/RIGHTBUS block
- TOP block for G3D/MFC/LCD0/ISP/CAM/FSYS/MFC/PERIL/PERIR

OK, I'll fix it using only two interrupt for dual-core.

That way you avoid a goto, especially since the "goto out" isn't actually
an "out", it's still doing stuff at the end of the funciton.

Please consider samsung,exynos3 instead, so you don't have to update this table
for every SoC. We've talked about this before..

In general, I think we have too much code littered with soc_is_<foo>() going
on, so please try to avoid adding more for this SoC. Especially in cases where
you just want to bail out of certain features where we might already have
function pointers to control if a function is called or not, such as the
firmware interfaces.

There is a Kconfig consolidation patch submitted by me [1]. Please base your

There is a Kconfig consolidation patch submitted by me [1]. Please base your
code on that one to avoid merge conflicts.

There's no point in splitting these off in separate patches; fold them
into one patch that introduces the SoC dtsi, please.

Also, you missed your sign-off on one or two of the previous ones, but that
won't be a problem once they're folded in. :)

Finally, if the code is yours, and you're posting it, then Kyungmin should
probably have a Reviewed-by or Acked-by tag, not a Signed-off-by. See
Documentation/SubmittingPatches, section 12 and 13.

It's better to ask system lsi person. We don't know it well.
I got the guide about secondary boot from system lsi.
But, this patch was completely tested.

OK, I'll modify it as following:

 static int exynos_cpu_boot(int cpu)
 {
+       if (soc_is_exynos4212())
+               cpu = 0;
+
        exynos_smc(SMC_CMD_CPU1BOOT, cpu, 0, 0);
        return 0;
 }

OK, I'll remove goto statement and then modify it as your comment.

exynos_smc(SMC_CMD_CPU1BOOT, ...) is cpu hotplug SMC interface.
Exynos4212 is dual core processor.
Exynos4212 only have to boot cpu1 on smp boot.
So, Second parameter of exynos_smc is fixed by 0 which means cpu1.
It don't need to boot another cpu (ex. cpu2, cpu3 for quad core processor).
But In case of quad core processor (ex. Exynos4412), 
It need to boot another cpu and specify parameter of booting core.
As I know, Exynos3250 is dual core. 
So It can be included 1st condition too.

Sangbeom,

This patchset included only exynos3250.dtsi without exynos3.dtsi.
So, I added only "samsung,exynos3250" compatible name.

Do you prefer to add SoC version as following?
+       "samsung,exynos3",
+       "samsung,exynos3250",

or ?
+       "samsung,exynos3",

Do you prefer dt helper function such as following function instead of new soc_is_xx() ?
- of_machine_is_compatible("samsung,exynos3250")

If you are OK, I'll use of_machine_is_compatible() instead of soc_is_xx().

I think of_machine_is_compatible() is not proper alternative method.
of_machine_is_compatible can be only used if CONFIG_OF is enabled.

I think of_machine_is_compatible() is not proper alternative method.
of_machine_is_compatible can be only used if CONFIG_OF is enabled.

Is the smc API defined to ignore the first argument of SMC_CMD_CPU1BOOT 
command for dual core systems or it is defined as should be zero?

CONFIG_OF is enabled by definition, that wouldn't be a problem. However,
of_machine_is_compatible() doesn't solve the problem that Olof mentioned,
you still make runtime-decisions based on the SoC ID, which you should not.

Instead, the code should be restructured so it doesn't have to know which
SoC is being used. If some machines work differently from others, that should
be local knowledge within the device driver, and it can use for instance
a DT property of the device node that describes the register set the driver
is using.

There is no direct relation between dts file names and compatible string 
(although usually they correspond). You don't need exynos3.dtsi (at 
least until another SoC from this family shows up).

This is actually a good question. If adding exynos3 anyway, it probably 
wouldn't hurt to add exynos3250 anyway, to avoid adding it in future if 
some SoC specific quirks show up, especially when both of compatible 
strings need to be documented anyway.

First of all, there is still a lot of code in mach-exynos/ using the 
soc_is_xx() macros, so having some SoCs use them and other SoCs use 
of_machine_is_compatible() wouldn't make the code cleaner.

For now, I wouldn't mind adding soc_is_exynos3250(), but in general such 
code surrounded with if (soc_is_xx()) blocks should be reworked to use 
something better, for example function pointers, as Olof suggested.

Tomasz

There is no direct relation between dts file names and compatible string 
(although usually they correspond). You don't need exynos3.dtsi (at 
least until another SoC from this family shows up).

This is actually a good question. If adding exynos3 anyway, it probably 
wouldn't hurt to add exynos3250 anyway, to avoid adding it in future if 
some SoC specific quirks show up, especially when both of compatible 
strings need to be documented anyway.

First of all, there is still a lot of code in mach-exynos/ using the 
soc_is_xx() macros, so having some SoCs use them and other SoCs use 
of_machine_is_compatible() wouldn't make the code cleaner.

For now, I wouldn't mind adding soc_is_exynos3250(), but in general such 
code surrounded with if (soc_is_xx()) blocks should be reworked to use 
something better, for example function pointers, as Olof suggested.

What did Kyungmin do then? If you submitted the patch to him, and he
sent it back to you, you should be listed twice, although you could
just as easily leave him out.

I believe the intention was to squash all the patches related to 
exynos3250.dtsi into a single patch called "ARM: dts: Add device tree 
sources for Exynos3250". To retain authorship information, signed-off-by 
tags should be merged from all those patches too.

Sorry, It has happen a confusion due to my mistake.

As I reply on other patch as Olof comment, I'll use 'Acked-by' instead
of  'Signed-off' for Kyungmin Park.

I thought 'function pointers' method instead of soc_is_xxx() macro as following two case:
I need more detailed explanation/example of "for example function pointers, as Olof suggested." sentence.

[case 1]
Each Exynos SoC has other function pointers according to compatible name of DT.

For example, arch/arm/mach-exynos/firmware.c

static const struct firmware_ops exynos_firmware_ops = {
	.do_idle		= exynos_do_idle,
	.set_cpu_boot_addr	= exynos_set_cpu_boot_addr,
	.cpu_boot		= exynos_cpu_boot,
};
static const struct firmware_ops exynos3250_firmware_ops = {
	.do_idle		= exynos_do_idle,
	.set_cpu_boot_addr	= exynos4212_set_cpu_boot_addr,
	.cpu_boot		= exynos3250_cpu_boot,
};

static const struct firmware_ops exynos4212_firmware_ops = {
	.do_idle		= exynos_do_idle,
	.set_cpu_boot_addr	= exynos4212_set_cpu_boot_addr,
	.cpu_boot		= exynos4212_cpu_boot,
};

struct secure_firmware {
	char *name;
	const struct firmware_ops *ops;
} exynos_secure_firmware[] __initconst = {
	{ "samsung,secure-firmware",		&exynos_firmware_ops },
	{ "samsung,exynos3250-secure-firmware", &exynos3250_firmware_ops },
	{ "samsung,exynos4212-secure-firmware", &exynos4212_firmware_ops },
};


[case 2]
Delete all the soc_is_xxx() macro and then
use only get_samsung_soc_id() function as following:
	 
	switch (get_samsung_soc_id()) {
	case EXYNOS3250_SOC_ID:
		// ...
		break;
	case EXYNOS4210_CPU_ID:
		// ...
		break;
	case EXYNOS4212_CPU_ID:
		// ...
		break;
	case EXYNOS4412_CPU_ID:
		// ...
		break;
	case EXYNOS5250_SOC_ID:
		// ...
		break;
	case EXYNOS5420_SOC_ID:
		// ...
		break;
	case EXYNOS5440_SOC_ID:
		// ...
		break;
	};

I thought 'function pointers' method instead of soc_is_xxx() macro as following two case:
I need more detailed explanation/example of "for example function pointers, as Olof suggested." sentence.

[case 1]
Each Exynos SoC has other function pointers according to compatible name of DT.

For example, arch/arm/mach-exynos/firmware.c

static const struct firmware_ops exynos_firmware_ops = {
	.do_idle		= exynos_do_idle,
	.set_cpu_boot_addr	= exynos_set_cpu_boot_addr,
	.cpu_boot		= exynos_cpu_boot,
};
static const struct firmware_ops exynos3250_firmware_ops = {
	.do_idle		= exynos_do_idle,
	.set_cpu_boot_addr	= exynos4212_set_cpu_boot_addr,
	.cpu_boot		= exynos3250_cpu_boot,
};

static const struct firmware_ops exynos4212_firmware_ops = {
	.do_idle		= exynos_do_idle,
	.set_cpu_boot_addr	= exynos4212_set_cpu_boot_addr,
	.cpu_boot		= exynos4212_cpu_boot,
};

struct secure_firmware {
	char *name;
	const struct firmware_ops *ops;
} exynos_secure_firmware[] __initconst = {
	{ "samsung,secure-firmware",		&exynos_firmware_ops },
	{ "samsung,exynos3250-secure-firmware", &exynos3250_firmware_ops },
	{ "samsung,exynos4212-secure-firmware", &exynos4212_firmware_ops },
};


[case 2]
Delete all the soc_is_xxx() macro and then
use only get_samsung_soc_id() function as following:
	 
	switch (get_samsung_soc_id()) {
	case EXYNOS3250_SOC_ID:
		// ...
		break;
	case EXYNOS4210_CPU_ID:
		// ...
		break;
	case EXYNOS4212_CPU_ID:
		// ...
		break;
	case EXYNOS4412_CPU_ID:
		// ...
		break;
	case EXYNOS5250_SOC_ID:
		// ...
		break;
	case EXYNOS5420_SOC_ID:
		// ...
		break;
	case EXYNOS5440_SOC_ID:
		// ...
		break;
	};

This is probably the right solution. Another would be to detect which 
firmware ops to use by matching root node with particular SoC compatible 
strings.

This is probably the right solution. Another would be to detect which 
firmware ops to use by matching root node with particular SoC compatible 
strings.

OK, I'll modify firmware.c using this method on separated patch apart from Exynos3250 patchset.
But, I want to implment it after completed Exynos3250 patchset.
Because Exynos3250 patchset needs other patch such as following patch:
Following patches has not yet to be confirmed or merged.
