Hi,
We need to support rk3036 soc platform via upstream, there are
3 primary parts for the initial release of minimum system: dts,
pinctrl, and clock tree for rk3036, and additional, we can use
these startup and run to init processs.
Thanks.
Changed in v4:
- add some basic IP modules on rk3036.dtsi
- optimized supporting smp codes
Changed in v3:
- optimized some codes based on v2
- removed the patch "initial set time for rtc-hym8563" (useless)
- removed the patch "pinctrl" (approved)
Changed in v2:
- based on v1, add clock controller documentation
- enable timer5 startup
- add smp for cpu1
- initial set time for rtc-hym8563
Changes in v1:
- add dts, pinctrl and clock tree for rk3036 soc platform
The patchset (8):
8) rockchip: make sure timer5 is enabled on rk3036 platforms
7) ARM: dts: enable smp for rk3036
6) ARM: rockchip: add support smp for rk3036
5) ARM: dts: rockchip: add core rk3036 dts
4) clk: rockchip: add new pll-type for rk3036 and similar socs
3) clk: rockchip: add clock controller for rk3036
2) clk: rockchip: add dt-binding header for rk3036
1) dt-bindings: add documentation of rk3036 clock controller
Changes in v4:

Add the devicetree binding for the cru on the rk3036 which quite similar
structured as previous clock controllers.

+* Rockchip RK3036 Clock and Reset Unit
+
+The RK3036 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3036-cru"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+ If missing pll rates are not changeable, due to the missing pll lock status.
+
+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 the dt-bindings/clock/rk3036-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+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:
+ - "xin24m" - crystal input - required,
+ - "ext_i2s" - external I2S clock - optional,
+ - "ext_gmac" - external GMAC clock - optional
+
+Example: Clock controller node:
+
+ cru: cru@20000000 {
+ compatible = "rockchip,rk3036-cru";
+ reg = <0x20000000 0x1000>;
+ rockchip,grf = <&grf>;
+
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller:
+
+ uart0: serial@20060000 {
+ compatible = "snps,dw-apb-uart";
+ reg = <0x20060000 0x100>;
+ interrupts = <GIC_SPI 20 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ reg-io-width = <4>;
+ clocks = <&cru SCLK_UART0>;
+ };

Add the dt-bindings header for the rk3036, that gets shared between
the clock controller and the clock references in the dts.

From: Heiko Stuebner <heiko@sntech.de>
The dual-core Cortex A7 rk3036 is a bit special in that it does not allow
to control the actual powerdomain of the cpu cores, while the rest of the
smp-bringup like reset control and entry address handling stays the same.
Its bigger sibling, the quad-core rk3128 again allows powerdomain control.
So allow that case by introducing a separate smp-enable-method, that simply
disables powerdomain handling in the common code.
