This patchset support new Exynos3250 Samsung SoC based on Cortex-A7 dual core.
Exynos3250 is a System-On-Chip (SoC) that is based on 32-bit RISC processor
for Smartphone. It is desigend with the 28nm low-power high-K metal gate process
and provides the best performance features.

This patchset include some patches such as:
- Support booting of Exynos3250
- Supoort uart/mct/adc/gic/i2c/spi/power-domain/pmu/mshc/pwm/amba
- Support the clock control for Exynos3250 using common clk framework

[Pinctrl patch for Exynos3250]
The pinctrl patch for Exynos3250 has been merged in pinctrl.git of Linus Walleij
- [1] https://lkml.org/lkml/2014/4/23/72

This patchset is based on following git repo/branch.
- git repo : git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git
- branch   : for-next (Linux 3.15-rc1)

Changes from v3:
- Remove all dependency about following patchset to remove static memory
  mapping for SYSRAM[1] / PMU ([2] or [3]). If following patchset merged,
  I'll send a further patches to support SYSRAM/PMU for secondary CPU.
 [1] http://www.spinics.net/lists/arm-kernel/msg323011.html
 [2] https://lkml.org/lkml/2014/4/2/48
 [3] http://www.spinics.net/lists/arm-kernel/msg316013.html

Changes from v2:
- Remove static memory mapping about SYSRAM/PMU such as following patches:
  ARM: EXYNOS: Add IO mapping for non-secure SYSRAM of Exynos3250
  ARM: EXYNOS: Add IO mapping for PMU of Exynos3250
- Add description for secondary CPU boot of Exynos4212/Exynos3250
- Fix description in exynos_cpu_die() to remove particular SoC series
- Fix minor coding style
- Add documentation for Exynos3250 clock controller

Changes from v1:
- Add new "samsung,exynos3" compatible name
- Add comment about exynos_cpu_boot in Exynos4212
- Remove unnecessary 'goto' statement in firmware.c
- Use read_cpuid_part_number() function instead of assembler directly
- Post separated pinctrl patch from this patchset
  : https://lkml.org/lkml/2014/4/13/156
- Remove unused pmu interrupts due to Exynos3250 dual-core
- Cosolidate all the patches related to exynos3250.dtsi into one patch
- Fix gic compatible name to "cortex-a15-gic" because Cortex-A7 GIC is same
- Add sign-off of sender to all this patches
- Fix minor typo

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,

+* Samsung Exynos3250 Clock Controller
+
+The Exynos3250 clock controller generates and supplies clock to various
+controllers within the Exynos3250 SoC.
+
+Required Properties:
+
+- compatible: should be one of the following.
+  - "samsung,exynos3250-cmu" - controller compatible with Exynos3250 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.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/exynos3250.h header and can be used in device
+tree sources.
+
+Example 1: An example of a clock controller node is listed below.
+
+	cmu: clock-controller@10030000 {
+		compatible = "samsung,exynos3250-cmu";
+		reg = <0x10030000 0x20000>;
+		#clock-cells = <1>;
+	};
+
+Example 2: 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' property.
+
+	serial@13800000 {
+		compatible = "samsung,exynos4210-uart";
+		reg = <0x13800000 0x100>;
+		interrupts = <0 109 0>;
+		clocks = <&cmu CLK_UART0>, <&cmu CLK_SCLK_UART0>;
+		clock-names = "uart", "clk_uart_baud0";
+	};

Right, It is may mistake.
I'll resend this patch.

Yes, logically the flow would be same and code would be more readable.

I have noticed Leela Krishna Amudala's patch [1] that removes this 
distinction completely and simply uses generic code. Could you check if 
this works on Exynos3250 as well? If yes, then this patch could be 
dropped and Leela's one would be enough.

Although I believe we're approaching the point where everyone just uses
ARM Ltd designed CPUs, it should be remembered that the part number
field is designer specific, so if we were being strict, we'd check both
the part number and the designer fields together.

In original driver present in our internal tree I have separated several 
CMUs to account for certain factors caused by hardware design, which 
require such separation. Is there any reason why they were merged 
together into a single CMU again?

Any reason to have this empty array at all?

This is a hack. The real "fin_pll" is a mux driven by XOM pin which 
selects which clock input is used as main system oscillator. It should 
be implemented properly in this driver or at least appropriate comment 
should be added stressing the fact that it is a hack.

Are there only 2 gate block clocks? By the way, how are they going to be 
handled by respective drivers? There is no mainline support for them 
right now, but you should be aware that adding them will cause common 
clock framework to disable them if not claimed by any driver.

Are all these frequencies above calculated exactly? For correct 
operation of rate setting code, it is necessary for frequency values 
specified in these arrays to be exact, not rounded.

This patch should be applied independently of Exynos3250 support. 
Kukjin, what do you think?

Could you use references instead of re-specifying the whole tree 
hierarchy in every file a node is used?

Instead of

/ {
	pinctrl@11400000 {

	};
};

one may simply use

&pinctrl_0 {

};

You might just need to change the location of #include 
"exynos3250-pinctrl.dtsi" from top of exynos3250.dtsi to bottom of it.

Why only one CPU? I believe Exynos3250 is dual core. Also are physical 
IDs of the cores really 0 and 1? On Exynos4210 for example they are 
0x900 and 0x901, while on Exynos4212 they are 0xa00 and 0xa01. Please 
check this.

Please add label to the node, so it can be referenced from board dts

Oh, well, you also should move all nodes of on-SoC devices under a 
simple-bus node called soc. You can see the patch adding dts file for 
Exynos5260 for an example [1].

OK, I tested this patch[1] to turn on secondary CPu on Exynos3250.
I'll drop following patch on next posting(v5) by using Leela Krishna Amudala's patch [1].
- ARM: EXYNOS: Enter a15 lowpower mode for Exynos3250 based on Cortex-a7

I'll add cpu1 information.

> Also are physical IDs of the cores really 0 and 1? On Exynos4210 for example they are 0x900 and 0x901, while on Exynos4212 they are 0xa00 and 0xa01. Please check this.

The 'reg' property means only hardware id(hwid) of CPU.
You can check it on arm_dt_init_cpu_maps() in arch/arm/kernel/devtree.c.h.
or Documentation/devicetree/bindings/arm/cpus.txt.

Well, as described in Documentation/devicetree/bindings/arm/cpus.txt, on 
32-bit ARM v7 or later CPUs the "reg" property should be equal to the 
lower 24-bits of MPIDR value of given CPU, which in addition to core ID 
includes also cluster ID, which can be non-zero, even on single cluster 
SoCs (like it is on Exynos4210 and 4x12).

There is no need to suffix the RTC with _0, as there is just one RTC in 
the SoC. So in this case rtc: rtc@10070000 will be enough.

OK. In this case there are multiple instances of serial controller 
available so the _0 suffix is fine.

OK, I'll move nodes dependent on SoC under 'soc' dt node as example patch[1] except for 'amba-bus' dt node.

I checked the lower 24-bit of MPIDR value for Exynos3250 in arm_dt_init_cpu_maps().
- the lower 24-bit of MPIDR for CPU0 is '0x0'.

OK, I'll modify it without prefix('_0).

I don't see any reason why amba-bus node shouldn't be under soc node as

I didn't understand the correct meaning of 'simple-bus'.
OK, I'll move 'amba-bus' dt node under 'soc' dt node.

This patch just include clocks in CMU clocks without CMU_DMC/CMU_ISP.
I'll send a further patches to support CMU_DMC/CMU_ISP after verifying it.

OK, I'll add comment about it and if you ok, I'll send a further patchset to set relation
between fin_pll and xusbxti/xxti by reading XOM pin of chipid register.

OK, I'll add remaing clock gate of GATE_BLOCK as following.
- CLK_BLOCK_MFC MFC_BLK
- CLK_BLOCK_CAM CAM_BLK

When I implemnted exynos3250_vpll_rates array, I used 'VPLL PMS Value' in Exynos3250 TRM without modification.
This rate value of exynos3250_vpll_rates is correct.

I agree that in the end the block gates will have to be added. However
currently drivers do not request block gates and enable them.
Considering that common clock framework disables all unused clocks by
default, this will lead to all the gate block clocks being disabled,
which is not desired.

My opinion on this is that block gate clocks should be added in separate
patch along with patches adding code to get and enable them.

The TRM actually lists this as 267, 3, 2, 32768, and according to the
equation it will be 535000015 Hz. Looks like a typo in the data sheet,
as 266, 3, 2, 32768 gives 533000015, which is almost exactly 533 MHz.

which is almost exactly 445.5 MHz.

374250034. This one also looks like a typo. 123, 2, 2, 49512 would give

Well, after checking the values using PLL equation for VPLL, as
specified in TRM and used by clk-pll.c, the values don't match.

Keep in mind that the values must be exact, _not_ rounded, while in the
TRM they are rounded. Moreover it looks like several frequencies in TRM
are off by 1 in M coefficient. Please see above.

You're right.

OK, I'll remove the clocks of GATE_BLOCK on next posting(v6)

When I calculated fout with following data:
- 124, 2, 2, 49512 would give 374266514.1
- 123, 2, 2, 49512 would give 371266514.1.

I think below value is proper. 
- 123, 2, 2, 49512 would give 371266514.1.

Thanks for your point out.

So, I calculated fout of VPLL using PLL equation in Exynos3250 TRM.

OK, thanks.

By the way, if there are no other comments to v5 series than to this
patch, then you can simply send v6 of this single patch as a reply to v5.

Sorry, my bad, I made a typo as well ;). It should be 123, 2, 2, 49152.
The value I got was correct - 371250034.

According to the table above, shouldn't it be 533000015?

There is one more thing, I found when analyzing this. clk-pll.c actually
uses 65536 (actually shift by 16) instead of 65535 in the equation given
in TRM and this gives better values. See samsung_pll36xx_recalc_rate().

By using script

>>> fin = 24000000
>>> def pll(m,p,s,k):
...     print (fin * (m * 65536 + k)) / (65536 * p * 2**s)
...

I'm getting better values, e.g.

>>> pll(266, 3, 2, 32768)
533000000

>>> pll(123, 2, 2, 49152)
371250000

Considering the fact that for PLL36xx Exynos5250 TRM uses 65536 as well,
this is probably the right equation. So please recalculate the values
again using:

FOUT = (MDIV + K/65536) x FIN/(PDIV x 2^SDIV)

or just my script above run in Python 2.x interpreter.

Best regards,
Tomasz
