I should reword the commit description to be clearer, sorry about that: I
went with "exactly what I've done", but looking at the actual diff, it is
just a rename. What my brain was ticking on here was about removing clocks
that didn't really exist (uart_clk is not a fixed clock, etc), and adding
the ones that do exist.... but then again, the result, casually, is a rename.
Yes, some better explanation would help.
Will do for v2 then!
In any case... no, these clocks are not board-specific for two reasons:
1. AFAIK, these fixed clock outputs are from the SoC itself, not from
external components placed on the board, and
This would be fine.
2. Even if these were from external components, the SoC *needs* these
ones to work and any board that doesn't have these fixed XOs simply
wouldn't be able to work.
This is common pattern and Mediatek is not different here. In all cases
these are needed by SoC and in (almost?) all cases these should be
provided by board DTS. The DTS describes here the hardware, the board
has the clock thus the board DTS should define it.
Right. If external components are strictly necessary, physically, they're
still external components and not inside of the SoC, and anything external
*may* change depending on the (hardware) implementation.
Anyway - I was wondering if splitting this change in two commits would be
better to let people understand what's going on... probably it would, as
that would clearly show both the addition of the 32K/26M clocks and the
subsequent removal of the other two: I would at this point do that, what
do you think?
