Add the dt-bindings header for the rk3328, that gets shared between
the clock controller and the clock references in the dts.
Add softreset ID for rk3328.

+* Rockchip RK3328 Clock and Reset Unit
+
+The RK3328 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,rk3328-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/rk3328-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,
+ - "clkin_i2s" - external I2S clock - optional,
+ - "gmac_clkin" - external GMAC clock - optional
+ - "phy_50m_out" - output clock of the pll in the mac phy
+
+Example: Clock controller node:
+
+ cru: clock-controller@ff440000 {
+ compatible = "rockchip,rk3328-cru", "rockchip,cru", "syscon";
+ reg = <0x0 0xff440000 0x0 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@ff120000 {
+ compatible = "snps,dw-apb-uart";
+ reg = <0xff120000 0x100>;
+ interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ reg-io-width = <4>;
+ clocks = <&cru SCLK_UART0>;
+ };

The rk3328's pll and clock are similar with rk3036's,
it different with pll_mode_mask,there are different
control registers bit,
so these should be independent and separate from
the series of rk3328s.

The example shows other compatibles. IMO, I would drop them rather than

not sure I understand this description. In the patch (and TRM excerpt) I see
that the number of parents is down to only xin24m but the general handling is
similar to the rk3036 and thus reuses its operations.
The description makes it sound like there are operational differences (the
"different control register bit" part), so could you clarify this a bit
please?
Also, please move the pll addition before the addition of the clock-controller
in the series and move the pll-type addition also here from the controller
patch.
Some more below:

you're missing the other parts handling parents, like num_parents check
and the init.num_parents parameter.
The pll really has only one parent, xin24m, so we should handle this
correctly in the code, instead of having 2 times xin24m in the parent
array coming from the clock controller.

please don't duplicate the rk3036-ops assignment, when adding the
pll_rk3328 option to the rk3036 part suffices.
I'd think the pll-patch should look something like the
following (untested, so please test):
--------------- 8< -----------------
Subject: [PATCH] clk: rockchip: add new pll-type for rk3328
The rk3328's pll and clock are similar with rk3036's,
it different with pll_mode_mask,there are different
control registers bit,
so these should be independent and separate from
the series of rk3328s.
