This is a request for comments for the below patches.
Patch 1 is a cleanup I came up with while writing patch 2. I'm sending
it along because the other one depends on some things introduced
in it to compile cleanly.
Patch 2 adds COMMON_CLK support for all configurable internal
clock sources on alchemy socs.
Please have a look!
Thanks a lot,
Manuel Lauss

2.0.0
- remove the custom au_read/write{bwl} accessors as well as au_sync,
and replace them with __raw_readl/writel/wmb in all users.
- changes absolute register addresses to offsets from their base:
- rename the SYS_xxx definitions to AU1000_SYS_ so people know
that addresses have changed.
- add helpers to read/write SYS registers, and use them.
- removes unused register/bit definitions (unused hw blocks, ...)
- moves ethernet register/bit descriptions to au1000_eth driver.
It's not used there either, but I didn't want to lose it.
No functional changes.
Tested on DB1300 and DB1500.

2.0.0
Expose chip-internal configurable clocks to the common clk framework,
and fix a few drivers to take advantage of it.
The patch takes the frequencies and tree configuration set up by
the bootloader and runs with it; all boards should continue to
work without modifications. A few clocks for which I haven't yet
modified the drivers using them are force-enabled when firmware
has left them enabled (the clk framework disables all not yet
clk_enable()d ones late during boot). This whitelist will go away
eventually.
The set_rate logic in the muxes does not request rate changes from
upstream sources, nor does it change parents if it seems more
appropriate: I've kept this logic as simple as possible for
now. Source and rate changes have to be made manually at each pll
and mux.
Tested only on the DB1300 and DB1500 so far, but I see no functional
changes / errors on either board, I'll test on the other DB boards
I have soon as well.
Example clock summaries right after boot:

+ *
+ * Dividers:
+ * - 6 clock dividers with:
+ * * selectable source [one of the PLLs],
+ * * output divided between [2 .. 512 in steps of 2] (!Au1300)

+ * - up to 6 "internal" (fixed) consumers which:

+ * * divide this input by 1, 2, or 4 (and 3 on Au1300).
+ * * can be disabled separately.
+ *
+ * Misc clocks:
+ * - sysbus clock: CPU core clock (CPUPLL) divided by 2, 3 or 4.
+ * depends on board design and should be set by bootloader, read-only.
+ * - peripheral clock: half the rate of sysbus clock, source for a lot
+ * of peripheral blocks, read-only.
+ * - memory clock: clk rate to main memory chips, depends on board
+ * design and is read-only,
+ * - lrclk: the static bus clock signal for synchronous operation.
+ * depends on board design, must be set by bootloader,
+ * but may be required to correctly configure devices attached to
+ * the static bus. The Au1000/1500/1100 manuals call it LCLK, on

Thanks for the patch series! Both patches cover a lot of ground, but
I'll focus on #2. It would be best to split the driver changes out
separately. You can introduce the common clk changes but not compile
them in, then change the drivers, then add the logic to compile the new
common clock driver all as separate patches.

As stated above, in the first patch only introduce
arch/mips/alchemy/common/clock, but don't compile it here in the
Makefile.
A quick glance through clock.c below looks pretty good. I'll go through
it in more detail once the other parts of the series are split out.
Additionally, it would be cool to push this driver out to drivers/clk/
if you are so inclined. It looks like your header dependencies are not
so bad as to make that task impossible. Just a suggestion from me.
Regards,
Mike

I sent the first one along because the second doesn't compile without it.

I'll split them into pure clock framework and enablement parts.

This clock framework is for a single line of MIPS SoCs which are no longer
being developed by the manufacturer and I don't think it is reusable for any
other soc line currently in existence. I'd like to keep it within the mips tree
for that reason. (I find the ARM way of sprinkling the whole tree with
a single driver for each iteration of each custom on-chip peripheral on
each ARM chip [exaggerated of course] quite messy. But that's just me).
