This patch series is the new s5pv210 clock implementation
(using common clk framework).
This implementation is compatible with device tree definition and board files.
This patch series is based on linux-next and has been tested on goni and aquila
boards using board file.
This patch series require adding new registration method
for PLL45xx and PLL46xx, which is included in this patch series:

Replace clk_enable by clock_enable_prepare and clk_disable with clk_disable_unprepare.
Clock prepare is required by Clock Common Framework, and old clock driver didn`t support it.
Without it Common Clock Framework prints a warning.

+* Samsung S5PC110/S5PV210 Clock Controller
+
+The S5PV210 clock controller generates and supplies clock to various controllers
+within the SoC. The clock binding described here is applicable to all SoCs in
+the S5PC110/S5PV210 family.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "samsung,s5pv210-clock" - controller compatible with S5PC110/S5PV210 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Some of the clocks are available only
+on a particular S5PC110/S5PV210 SoC and this is specified where applicable.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/samsung,s5pv210-clock.h header and can be used in device
+tree sources.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xxti" - xtal - required
+ - "xusbxti" - USB xtal - required,
+
+
+Example: Clock controller node:
+
+ clock: clock-controller@7e00f000 {
+ compatible = "samsung,s5pv210-clock";
+ reg = <0x7e00f000 0x1000>;
+ #clock-cells = <1>;
+ };
+
+Example: Required external clocks:
+
+ fin_pll: clock-xxti {
+ compatible = "fixed-clock";
+ clock-output-names = "xxti";
+ clock-frequency = <12000000>;
+ #clock-cells = <0>;
+ };
+

+* Samsung S5PC110/S5PV210 Clock Controller
+
+The S5PV210 clock controller generates and supplies clock to various controllers
+within the SoC. The clock binding described here is applicable to all SoCs in
+the S5PC110/S5PV210 family.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "samsung,s5pv210-clock" - controller compatible with S5PC110/S5PV210 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Some of the clocks are available only
+on a particular S5PC110/S5PV210 SoC and this is specified where applicable.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/samsung,s5pv210-clock.h header and can be used in device
+tree sources.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xxti" - xtal - required
+ - "xusbxti" - USB xtal - required,
+
+
+Example: Clock controller node:
+
+ clock: clock-controller at 7e00f000 {
+ compatible = "samsung,s5pv210-clock";
+ reg = <0x7e00f000 0x1000>;
+ #clock-cells = <1>;
+ };
+
+Example: Required external clocks:
+
+ fin_pll: clock-xxti {
+ compatible = "fixed-clock";
+ clock-output-names = "xxti";
+ clock-frequency = <12000000>;
+ #clock-cells = <0>;
+ };
+
+ xusbxti: clock-xusbxti {
+ compatible = "fixed-clock";
+ clock-output-names = "xusbxti";
+ clock-frequency = <48000000>;
+ #clock-cells = <0>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller (refer to the standard clock bindings for information about
+ "clocks" and "clock-names" properties):
+
+ uart0: serial at 7f005000 {
+ compatible = "samsung,s5pv210-uart";
+ reg = <0x7f005000 0x100>;
+ interrupt-parent = <&vic1>;
+ interrupts = <5>;
+ clock-names = "uart", "clk_uart_baud2",
+ "clk_uart_baud3";
+ clocks = <&clock PCLK_UART0>, <&clocks PCLK_UART0>,
+ <&clock SCLK_UART>;
+ status = "disabled";
+ };

Although, this is a valid patch, I don't think it is related by any way to
migration of S5PV210 to common clock framework. So, IMHO, this patch should
be send separately, not as a part of this series.
Best regards,
Tomasz

Hi Mateusz,
Generally this patch looks good, but I have some minor nitpicks, that I
would like to be fixed.

nit: I haven't noticed this when reviewing previous patch, but please tone
down those errors messages a bit, by removing the exclamation mark (and the
space before it). We shouldn't be shouting at users. ;)

Hmm, ret already contains the error value returned by clk_prepare_enable()
here, so this looks like a copy paste error.

nit: I haven't noticed this when reviewing previous patch, but please tone
down those errors messages a bit, by removing the exclamation mark (and the
space before it). We shouldn't be shouting at users. ;)

Hmm, I'm not sure if all the boards must always provide both of them.
Actually it looks like the correct statement here would be "At least one of
the above clocks should be specified.".

NAK.
Please don't use headers from mach/ or plat/ directories in drivers, as
this will break future enablement of multiplatform support for S5PV210.

These three macros above does not seem to be used anywhere in this driver.
You can either remove them or change the driver to use them, as I can see
several places they would be appropriate. See below.

I think the four fixed rate clocks above should be assigned IDs too, to
allow referencing them from device tree. The external fixed rate clocks are
an exception to this, because they are specified in device tree using
separate nodes.

This CLK_IGNORE_UNUSED in the three clocks above does not look correct to
me. It should be responsibility of the driver to claim the clock and
control it. CLK_IGNORE_UNUSED should be rather used as last resort, for
example if there is no driver yet, but the clock must be kept enabled.

You should be careful with this kind of hack, because the DACPHY index
introduced here, when first used in DT, would become an ABI, support for
which would have to be kept in future.
There are three possible ways to deal with this:
1) remove this and thus break DAC support (does any existing board file
use it?),
2) implement this hack only for board files, without assigning a clock
specifier index for this clock and thus making it unavailable for DT.
3) implement this properly,
While option 3 would be the best one, I understand that it would require a
significant amount of work, so other choices might better for now. Option
1, if there are board files that have working DAC, will introduce a
regression, so it isn't really good. I guess we could go with 2) for now.

These aliases should not have NULL here. I belive this is to allow looking
these clocks up from board files, but this can be done using clk_get_sys()
and passing appropriate device name to the function.
This would also make the X in mout_fimcX redundant, so the clocks could be
specified as follows:
ALIAS(MOUT_FIMC2, "s5pv210-fimc.0", "mout_fimc"),
ALIAS(MOUT_FIMC1, "s5pv210-fimc.1", "mout_fimc"),

Hmm. This is a bit problematic. I believe the reason for exporting this is
exactly the same as for mout_fimcX. Am I right?
I believe there should be some way to do this kind of lookup from platform
code, without the need to add fake aliases for the clocks. Mike, do you
have any suggestsions?

This one if fine, as the PWM clocksource driver does not have a struct
device bound to it. (Generally speaking, this should be fixed by using
clk_get_sys() in that driver, but this is a material for separate patches.)

This one is needed by s5pv210-cpufreq indeed, but it also needs sclk_dmc0
and hclk_msys, which don't seem to have aliases defined in this driver.
However I also believe that s5pv210-cpufreq should be fixed to use
clk_get_sys(), with some made up device name, e.g. "s5pv210-cpufreq".

Instead of moving the successful path under the if, what about calling

Coding style: Braces should be used consistently, i.e. if used for "if"
clause, then should be used for "else" clause as well and vice versa.
Also you don't even need this else, because panic() does not return.

Hmm, I wonder if it's the right assumption. Maybe it would be better to
simply fail here? I'd like to hear other opinions on this.

Also if you could register here a fixed factor clock with 1:1 factor that
would just have the right parent clock set, instead of fixed rate clock,
the clock tree would be closer to reality.

What about XOM value when booting without device tree? Shouldn't you have
some way to read XOM value in platform code and pass it here, like it was
done in Exynos4 clock driver before we dropped non-DT support for Exynos?
Otherwise looks good.

Hmm, I'm not sure if all the boards must always provide both of them.
Actually it looks like the correct statement here would be "At least one of
the above clocks should be specified.".

These three macros above does not seem to be used anywhere in this driver.
You can either remove them or change the driver to use them, as I can see
several places they would be appropriate. See below.

I think the four fixed rate clocks above should be assigned IDs too, to
allow referencing them from device tree. The external fixed rate clocks are
an exception to this, because they are specified in device tree using
separate nodes.

This CLK_IGNORE_UNUSED in the three clocks above does not look correct to
me. It should be responsibility of the driver to claim the clock and
control it. CLK_IGNORE_UNUSED should be rather used as last resort, for
example if there is no driver yet, but the clock must be kept enabled.

You should be careful with this kind of hack, because the DACPHY index
introduced here, when first used in DT, would become an ABI, support for
which would have to be kept in future.
There are three possible ways to deal with this:
1) remove this and thus break DAC support (does any existing board file
use it?),
2) implement this hack only for board files, without assigning a clock
specifier index for this clock and thus making it unavailable for DT.
3) implement this properly,
While option 3 would be the best one, I understand that it would require a
significant amount of work, so other choices might better for now. Option
1, if there are board files that have working DAC, will introduce a
regression, so it isn't really good. I guess we could go with 2) for now.

These aliases should not have NULL here. I belive this is to allow looking
these clocks up from board files, but this can be done using clk_get_sys()
and passing appropriate device name to the function.
This would also make the X in mout_fimcX redundant, so the clocks could be
specified as follows:
ALIAS(MOUT_FIMC2, "s5pv210-fimc.0", "mout_fimc"),
ALIAS(MOUT_FIMC1, "s5pv210-fimc.1", "mout_fimc"),

Hmm. This is a bit problematic. I believe the reason for exporting this is
exactly the same as for mout_fimcX. Am I right?
I believe there should be some way to do this kind of lookup from platform
code, without the need to add fake aliases for the clocks. Mike, do you
have any suggestsions?

This one if fine, as the PWM clocksource driver does not have a struct
device bound to it. (Generally speaking, this should be fixed by using
clk_get_sys() in that driver, but this is a material for separate patches.)

This one is needed by s5pv210-cpufreq indeed, but it also needs sclk_dmc0
and hclk_msys, which don't seem to have aliases defined in this driver.
However I also believe that s5pv210-cpufreq should be fixed to use
clk_get_sys(), with some made up device name, e.g. "s5pv210-cpufreq".

Instead of moving the successful path under the if, what about calling

Coding style: Braces should be used consistently, i.e. if used for "if"
clause, then should be used for "else" clause as well and vice versa.
Also you don't even need this else, because panic() does not return.

Hmm, I wonder if it's the right assumption. Maybe it would be better to

Also if you could register here a fixed factor clock with 1:1 factor that
would just have the right parent clock set, instead of fixed rate clock,
the clock tree would be closer to reality.

What about XOM value when booting without device tree? Shouldn't you have
some way to read XOM value in platform code and pass it here, like it was
done in Exynos4 clock driver before we dropped non-DT support for Exynos?
Otherwise looks good.
