The series of patches represent support of Exynos 5410 SoC
The Exynos 5410 is the first Samsung SoC based on bigLITTLE architecture
Patches add new platform description, support of clock controller and device
tree for Exynos 5410.
Has been build on Linux Kernel v3.15-rc1
Has been tested on: 1) Exynos 5410 reference board (exynos_defconfig)
2) Odroid-XU board (exynos_defconfig)
I hope, this will be commited to Linux v3.15...
Tarek.

+* Samsung Exynos5410 Clock Controller
+
+The Exynos5410 clock controller generates and supplies clock to various
+controllers within the Exynos5410 SoC.
+
+Required Properties:
+
+- compatible: should be "samsung,exynos5410-clock"
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #clock-cells: should be 1.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/exynos5410.h header and can be used in device
+tree sources.
+
+External clock:
+There is clock that is generated outside the SoC. It is expected
+that it is defined using standard clock bindings with following
+ - compatible: should be "samsung,exynos5410-oscclk"
+
+Example 1: An example of a clock controller node is listed below.
+
+ clock: clock-controller@0x10010000 {
+ compatible = "samsung,exynos5410-clock";
+ reg = <0x10010000 0x30000>;
+ #clock-cells = <1>;
+ };
+
+Example 2: Required external clock.
+
+ fixed-rate-clocks {
+ oscclk {
+ compatible = "samsung,exynos5410-oscclk";
+ clock-frequency = <24000000>;
+ };
+ };
+
+Example 3: 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@12C20000 {
+ compatible = "samsung,exynos4210-uart";
+ reg = <0x12C00000 0x100>;
+ interrupts = <0 51 0>;
+ clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
+ clock-names = "uart", "clk_uart_baud0";
+ };

* [PATCH v8 2/3] clk: exynos5410: register clocks using common clock framework

The EXYNOS5410 clocks are statically listed and registered
using the Samsung specific common clock helper functions.

+* Samsung Exynos5410 Clock Controller
+
+The Exynos5410 clock controller generates and supplies clock to various
+controllers within the Exynos5410 SoC.
+
+Required Properties:
+
+- compatible: should be "samsung,exynos5410-clock"
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #clock-cells: should be 1.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/exynos5410.h header and can be used in device
+tree sources.
+
+External clock:
+There is clock that is generated outside the SoC. It is expected
+that it is defined using standard clock bindings with following
+ - compatible: should be "samsung,exynos5410-oscclk"
+
+Example 1: An example of a clock controller node is listed below.
+
+ clock: clock-controller at 0x10010000 {
+ compatible = "samsung,exynos5410-clock";
+ reg = <0x10010000 0x30000>;
+ #clock-cells = <1>;
+ };
+
+Example 2: Required external clock.
+
+ fixed-rate-clocks {
+ oscclk {
+ compatible = "samsung,exynos5410-oscclk";
+ clock-frequency = <24000000>;
+ };
+ };
+
+Example 3: 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 at 12C20000 {
+ compatible = "samsung,exynos4210-uart";
+ reg = <0x12C00000 0x100>;
+ interrupts = <0 51 0>;
+ clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
+ clock-names = "uart", "clk_uart_baud0";
+ };

We need this memory region because boot address for exynos5410 located

Is there really no way to map this region dynamically in the entity
(driver, source file, whatever) that actually uses it? The goal is to
get rid of all the static mappings entirely, so adding new one makes us
further from it.

This looks like a fix that's probably not specific to the 5410 and maybe
deserves it's own patch?

This looks like a fix that's probably not specific to the 5410 and maybe
deserves it's own patch?

I also boot tested (to initramfs) on my odroid-XU and see the 4 "big"
cores booted. Presumably I'm still missing the u-boot/firmware magic
for the little cores.

Hi,
Since I've started enforcing reference-based DT syntax due to multiple
advantages over the plain full-tree based one, you should do the same
for your dts/i files. You can take the series adding support for
Exynos5260 as an example:

Hi,
Since I've started enforcing reference-based DT syntax due to multiple
advantages over the plain full-tree based one, you should do the same
for your dts/i files. You can take the series adding support for
Exynos5260 as an example:
