Hello Simon,
To be made to clk_fixed_rate_ofdata_to_plat_(...) in
drivers/clk/clk_fixed_rate.c as it does not currently call
dev_has_ofnode(dev).
Ah OK. So the call stack is something like:
dev_read_u32_default()
dev_ofnode() - returns ofnode_null
ofnode_read_u32_default()
ofnode_read_u32_index
fdt_getprop(NULL, -1, ...) // guess
And I see that I put assert() in some of the ofnode_read..() functions
because I don't have tests for passing an invalid ofnode.
So perhaps fdt_offset_ptr_() should check for NULL and return? I
haven't traced it though.
In previous patch
[PATCH 3/3] libfdt: Check fdt_offset_ptr() return value unconditionally
that approach seems to have been rejected, and these dev_read_*() fixes
were implemented as a replacement.
