Hi Simon,

For my rk3399(64bit) dts, the address is described as below:

#address-cells = <2>; reg = <0x0 0xfe320000 0x0 0x4000>;

not like 32-bit soc which reg address describe like: reg = <0xfe320000 0x4000>;

There should have some update for this dts decode, right?

like: map_sysmem() regmap_init_mem_platdata()

Do you have a idea to update all these kind of function call?

It will be very great if you can send a patch for it.

Thanks,

Yes I think so.

But first I'd like to understand why we need to use of-platdata on this very modern SoC. Can you tell me the maximum SPL size you can support on this SoC? I thought you had removed the 30KB limit?

Using of-platdata only saves 3-4KB.
