I'm very pleased to see that you describe the clock topology using DT. In general I think your patch looks fine, but I have some comment related to the multiplatform integration, please see below. > diff --git a/drivers/clk/Makefile b/drivers/clk/Makefile > index 7b11106..3e64ac4 100644 > --- a/drivers/clk/Makefile > +++ b/drivers/clk/Makefile > @@ -32,6 +32,8 @@ obj-$(CONFIG_ARCH_VT8500) += clk-vt8500.o > obj-$(CONFIG_ARCH_ZYNQ) += zynq/ > obj-$(CONFIG_ARCH_TEGRA) += tegra/ > obj-$(CONFIG_PLAT_SAMSUNG) += samsung/ > +obj-$(CONFIG_ARCH_SHMOBILE) += shmobile/ > +obj-$(CONFIG_ARCH_SHMOBILE_MULTI) += shmobile/ Here I believe it is enough that you only use CONFIG_ARCH_SHMOBILE_MULTI. Building common clocks to coexist with the old legacy board code does not make any sense IMO. If you think it makes sense for some reason, please explain why. =) > diff --git a/drivers/clk/shmobile/Makefile b/drivers/clk/shmobile/Makefile > new file mode 100644 > index 0000000..6a26eb6 > --- /dev/null > +++ b/drivers/clk/shmobile/Makefile > @@ -0,0 +1,5 @@ > +ifeq ($(CONFIG_COMMON_CLK), y) > +obj-$(CONFIG_ARCH_EMEV2) += clk-emev2.o > +endif I don't think you would need the above ifeq/endif wrapper if you only used CONFIG_ARCH_SHMOBILE_MULTI above. Apart from that it looks good to me. And, yes, I have tested this on my KZM9D board together with multiplatform and it works very well!
