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 fix the offset of CPU boot address and don't need to send smc call
of SMC_CMD_CPU1BOOT command for secondary CPU boot because Exynos3250 removes
WFE in secure mode.

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

This patch add Exynos3250's SoC ID. Exynos 3250 is System-On-Chip(SoC) that
is based on the 32-bit RISC processor for Smartphone. Exynos3250 uses Cortex-A7
dual cores and has a target speed of 1.0GHz.

1.8.0
The Exynos3250 clocks are statically listed and registered using the
Samsung specific common clock helper functions. Both device tree based
clock lookup and clkdev based clock lookups are supported.

+* 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.

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?

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.

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
