Hi Sascha,
This is an update of the patch series below, which had gone through the
review and almost hit the v3.1 (it missed the last pull request Arnd
sent to Linus just for one day or so).
[PATCH v4 0/2] Add device tree support for i.mx51/53 boards
http://thread.gmane.org/gmane.linux.drivers.devicetree/7048
I was planning to hold the series until we have a iomuxc binding to
totally remove the dependency on non-dt board files. But as a cross
platform topic, it needs to take more time to get it settled down,
while I'm concerned by that people keep adding stuff into non-dt board
files with ignoring DT support. I'm here to revisit the series and
trying to get it merged in the coming merge window, so that we have
a base to ask people to move to DT.
Changes since v4:
* Rebase onto imx-features branch
* Have devices in soc dtsi as "disabled" and explicitly enable the
ones in board dts as "okay"
* Utilize of_irq_init() infrastructure added by Rob Herring recently

In the general case, from the above code fragment, I'd say you are. The timer init stuff is supposed to be for bringing up the timers. We do have an early init callback which can be used for this - which gets things like the clk stuff up and running from immediately after the page tables have been setup and initial device mappings put in place - before any drivers or even IRQ controllers have been initialized. ^ permalink raw reply [flat|nested] 16+ messages in thread

I agree with the suggestion below, but I'm trying to reuse non-dt setup as much as possible with minimum changes and impact to non-dt case.

For dt case, these clock frequencies should come from device tree. I was trying to keep it as it is until we finalize the clock bindings or the need of different frequency setup shows up. Now, the need shows up. I will add a new function call mx51_clocks_init_dt() with zero parameter in clock-mx51-mx53.c parsing the clock frequencies from device tree and the calling into mx51_clocks_init(...) with these frequencies as the parameters. The updated patch will come soon. Thanks for the input. Glad to see people are actually planning to move their board setup to DT. -- Regards, Shawn ^ permalink raw reply [flat|nested] 16+ messages in thread
