Aren't they compatible?



Are you saying that the spi driver is compatible with 2k0500 ?

Didn't you say this through 11 previous revisions?


Yes, did I understand your meaning incorrectly ?

Thanks,

Yes.  and the 2k1000 spi hardware was same with 2k0500 common type spi
hardware.

but afterwards, it may be necessary to implement a clock drvier for
2k0500, because the spi driver was use "devm_clk_get_optional()" to
get clock and not use "of_property_read_u32(np, "clock-frequency",
&clk)",  But this seems to have nothing to do with bindings.
