Each entry in the clock table specifies a number of individual bits in
registers, for contolling clock reset, gaiting, etc. These reg/bit were
packed into a u16 to save space. The combined value is difficult to
understand when reviewing the clock table entries.

Introduce a "struct regbit" which still occupies only 16 bits, but
allows the register and bit values to be specified explicitly. Convert
all previous uses of u16 for reg/bit into "struct regbit".

The bulk of this patch converts the clock table to use struct regbit,
making use of the RB() helper macro. The conversion was automated by
script, and as a further verification, the compiled binary of the table
was compared before/after the change (with objdump -D).

The clk_rdesc_set() function now checks for zero reg/bit internally.
This allows callers of that function to remove those checks.

I totally agree.

I was sure the structure would be bigger than 2B but yeah, gcc seems to
keep it small. However if at some point we add another member, we
might consider packing it.

I will trust your tool on the conversion.

Here and below, I would really prefer a "* 4" and a "/ 4". IMHO
shifts should stay reserved to bit operations. Here, what we want
is to convert a 1-byte offset into a 4-byte offset, thus the operation
is a multiplication. Even in -O0, all compilers would convert this into
a shift operation in the end. I believe we shall not sacrifice
readability in situations like that, were the optimization is trivial
for the tools.

Same here.

'bit' being an offset, is it correct to refuse writing BIT(0) ?

Could you unify the how reg is accessed here and below? I think I have
a slight preference for:

u32 __iomem *reg = clocks->reg + (rb.reg * 4);

Thanks,

If we should need to expand this, eg. to handle something more
complicated than a single-bit control, then I would probably want to
rename the structure as well.

I'm going to check again using objdump, just to make sure nothing slips through.

Reasonable, I'll make the change.

This replaces the check that callers previously did on the combined u16 value:

        if (g->reset)
                 clk_rdesc_set(clocks, g->reset, 1);

As you can see, it used zero as a special value to indicate "no reset
bit". I just kept the same approach, but moved the test inside the
function, to streamline the callers.

Of course, this means we cannot control a BIT(0) at register offset=0.
This is okay on RZ/N1 since offset=0 is an unrelated USB mode
configuration register.

Yes, I will unify both.

So naturally, this test uncovered a difference. It seems that gcc
orders bitfields differently on x86 and ARM. So the tables did not
match exactly with the old packed u16 fomat.

It is a harmless difference, but it can easily be eliminated, by
swapping the fields within 'struct regbit'. Now the tables are really
identical.

Patch v2 to follow shortly.
