+Mediatek MT8135 Clock Controller
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The Mediatek MT8135 clock controller generates and supplies clock to various
+controllers within Mediatek MT8135 SoC.
+
+Required Properties:
+
+- compatible: should be one of following:
+ - "mediatek,mt8135-topckgen" : for topckgen clock controller of MT8135.
+ - "mediatek,mt8135-apmixedsys" : for apmixed_sys (PLLs) of MT8135.
+ - "mediatek,mt8135-infracfg" : for infra_sys clock controller of MT8135.
+ - "mediatek,mt8135-pericfg" : for peri_sys clock controller of MT8135.
+
+- 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/mt8135-clk.h header and can be used in device tree sources.
+
+Example: I2C controller node that consumes the clock generated by the clock
+ controller (refer to the standard clock bindings for information about
+ "clocks" and "clock-names" properties):
+
+ pericfg: pericfg at 10003000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "mediatek,mt8135-pericfg";
+ reg = <0 0x10003000 0 0x1000>;
+ #clock-cells = <1>;
+ };
+
+ i2c0: i2c at 1100d000 {
+ compatible = "mediatek,mt8135-i2c", "mediatek,mt6589-i2c";
+ reg = <0 0x1100d000 0 0x70>, <0 0x11000300 0 0x80>;
+ interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_LOW>;
+ clock-div = <16>;
+ clocks = <&pericfg PERI_I2C0_CK>, <&pericfg PERI_AP_DMA_CK>;
+ clock-names = "main", "dma";
+ };

You use pericfg and infracfg which will be used by other drivers as
well. So please use syscon for this driver. As it is no longer a
platform device it is present early in boot.
The changes should look something like the patch beneath. Please
beware that it does only show the general concept and may not even
compile. I asked Sascha to implement the reset controller as part of
the clk driver, as the registers addresses are mixed between both,
clock and reset controller. Please coordinate with him to get them
integrated (even as one series or as incremental series).

I don't really understand the "as part of the clk driver part". I now
have replaced the devm_regmap_init_mmio with syscon_node_to_regmap
in the pericfg / infracfg drivers. Is that all that you want or do you
want me to move the source code to drivers/clk/mediatek?

Yes, I propose to move the source code to drivers/clk/mediatek.
Please have a look on other clock drivers which implement the reset
controller, e.g. rockchip.

Ok, I'm halfway through implementing this, but let's have weekend first.
Henry, If you're fine with this I'll change your clock series according
to Matthias suggestions.
