Arnd,
Sorry for yet another patchset for you :(
This one adds in support for SPEAr1310 and SPEAr1340. It supports:
- DT probing
- pinctrl drivers
- common clock framework
All you requested to get this upstream. :)
I have CC-ed Linus and Mike for their patches and would ask them for their Acks,
as this would evantually make through your ARM-SoC tree.
Few devices/drivers mentioned in dts files have their DT probing patches under
review.
Viresh Kumar (9):
SPEAr13xx: Add header files
SPEAr13xx: Add source files
SPEAr13xx: Add common clock framework support
pinctrl: SPEAr: Create macro for declaring GPIO PINS
pinctrl: Add SPEAr13xx pinctrl drivers
SPEAr13xx: Add dts and dtsi files
SPEAr13xx: Add compilation support
SPEAr13xx: Add defconfig
SPEAr: Update MAINTAINERS and Documentation

This patch adds SPEAr1310 and SPEAr1340's clock framework support. It is based
on earlier support for SPEAr3xx family.

Mike,
This would be required to go through Arnd's tree. So would be great if i can
have your comments/Ack here.

Same GPIO pins declarations would be required for other SoCs and that will be a
lot of lines of code. Its better to create common macros for it.

Linus,
This would be required to go through Arnd's tree. So would be great if i can
have your comments/Ack here.

Ideally we wouldn't have this file and put all the data into
the device tree of course but we're still lacking bindings for
that, so it's still ok for v3.5.

I think we can now probe localtimer from devicetree so you should
not need this one any more.

I'd also prefer if you could add bindings for GPT and probe
these interrupts and the GPT address from the devicetree
for the three spear platforms, that would make the code much
nicer in this area.

Can you go through this list one more time and check which ones are
still needed here? I think most of them can just get removed.

Why are the RAS control registers in a global header? It looks like you
only use them from the clock driver, so they can be moved into a local
header file there.

Again, I hope that we can remove this eventually when we have the DMA bindings,
but it's ok for now.

I'd like to see this done differently, with a ahci_spear driver derived from
ahci_platform that provides these functions in a modular driver that registers
to a spear specific identifier string and is able to do the platform specific
based on information it can find in the device tree. That would however require
changes to the existing ahci_platform code and I'd first like to hear what
Jeff and others have to say about this.

I've looked at all the platform specific bits and they look pretty good,
great work! I have ignored the pinctrl and clock drivers and hope that the
respective maintainers will be able to judge them well.
There are a few places where you still hardcode stuff that could be turned
into device tree properties, but those are corner cases and you have an
existing platform here that you've done a great amount of excellent cleanups
to in the last weeks, so my feeling is that all the platform code can go in
when you take care of the stuff that I've commented on, most of those things
should be simple.

To get platform data for ahci with DT, we need to do as mentioned by you.
But for now maybe we can accept this approach. Once somebody fix ahci
DT support as you suggested, we could create such drivers.

Wow, that was fast ;-)
Can you comment on the ones you did not address? In particular,
I'd like to understand why you put the SPEAR1310_RAS_CTRL*
register definitions into a globally visible header file.

Actually registers serves many different features. Clock, software controlled
chip selects for spi, etc. So really can't move to clock drivers.
I didn't wanted half part of a register in one file and other half in other.
So kept them here, so that these are accessible from all users.

Ok, fair enough. Right now we have only four platforms using this (davinci,
exynos, imx and now spear), but the code is still fairly well isolated.

It's still really ugly to have that in a global header file, including the
hardcoded register addresses.
What I'd suggest you do instead here is export a function to access the
registers from device drivers and add a new header file that contains
only this interface, the register offsets and the register definitions.
Then you can use proper of_iomap calls to get the area from the device
tree in the machine init code and it will be clear which drivers use the
interface because they have to explicitly include that header.

I will check if i can move this to clock.c for now, to move things quicker. :)

Most of this patch looks good to me accept for the two items below:
...

There is no exception handling at all in this function. Do you just
expect to fail at some later point?
...

Ditto.

This is what Russell suggested in his clkdev patch. We don't have to check clk *
returned from clk_register_*(). This will be done in clk_register_clkdev(), clk
lookup wouldn't be registered for failing clocks.
