Hmm yes I guess the panda needs the aux clock and there are various patches posted for that for quite a while but have not gotten merged. When I did my patches it seemed that Nishant's and my solution for getting the auxclk via DT was acceptable. Then Mike started doing all the clocks in DT and things changed. Mike, got any solution for us for v3.11 for the DT defined auxclk? > Yeah, I'm aware that some extra patches are being developped like the > omap clocks one: https://patchwork.kernel.org/patch/2541331/ but they > don't seem to be in -next.

I'd rather not postpone making omap4 DT only because I think at this point fixing the any DT related issues is way less work compared to maintaining and testing both legacy boot and DT boot.

That's also related to the auxclk.

The USB auxclk issue is fixable for DT boot, we just need to decide what's the best way to fix it. Regards, Tony

I understand your concerns but, please, cope with reality: the clock work is not in -next so this tends to make me think it won't reach 3.11. We're at -rc6 after all. Telling users that their system doesn't have any network because it was easier to maintain, is not something they will understand imho. Regards, Arnaud

Right, like I said: the idea is to have it usable with DT. And USB and Ethernet certainly are part of what I call usable. So is MMC, WLAN and DSS. I've certainly spent quite a bit of time on making sure panda works with DT, and I can assure you that fixing the USB extclock is easier than supporting the legacy boot with DT :) This issue can also be fixed with a clock alias if we don't have DT defined clocks ready for v3.11. It may take a few days for us to have the solution. But get getting a clock to a driver certainly is not a showstopper here. After all, that's what all drivers already do. Regards, Tony

Care to test the last patch just posted by Roger in thread " [PATCH 0/4] ARM: OMAP4: Panda USB Host support and DVI EDID fix"? That adds a clock alias for the EHCI auxclk so it should continue working until we have the DT clock patches available. Regards, Tony

I tried to test them but they don't apply on linux-next due to some pinctrl changes probably missing: Error: arch/arm/boot/dts/omap4-panda-common.dtsi:177.14-15 syntax error which corresponds to : 0x82 (PIN_INPUT_PULLDOWN | MUX_MODE4) Also, the patch 3 (ARM: dts: omap5-uevm: Provide USB Host PHY clock) doesn't apply as the omap5-uevm.dts doesn't exist. Which tree should I use to test the patches if it's not linux-next ? Also, you might want to know that drivers/usb/musb/omap2430.c doesn't build due to some typos (musb_resources vs musb_resouces).

Until it is merged, maybe try with Roger's earlier version of that patch that did not yet use the macros? > Also, the patch 3 (ARM: dts: omap5-uevm: Provide USB Host PHY clock) > doesn't apply as the omap5-uevm.dts doesn't exist. OK that's in Benoit's branch.

I've changed the missing macros with their values and now, it compiles and I can even ping the board, so works for me. Thanks, Arnaud

Sounds like we should have things mostly working with DT in mainline kernel by v3.11-rc1. I'm sure some minor fixes will be needed as more people start using it, but they should be all fixable either by binding changes, or by initializing missing things using platform data. Regards, Tony

We can now boot with device tree. If you don't want to update u-boot, you can boot with appended DTB with the following instructions: 1. Make sure you have the appended DTB support in .config CONFIG_ARM_APPENDED_DTB=y CONFIG_ARM_ATAG_DTB_COMPAT=y CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND=y 2. Build the zImage $ ARCH=arm CROSS_COMPILE=... make zImage 3. Build the device tree blobs $ ARCH=arm CROSS_COMPILE=... make dtbs 4. Append the correct panda dtb to zImage Depending on your hardware it's omap4-panda.dtb, omap4-panda-a4.dtb or omap4-panda-es.dtb. $ cat arch/arm/boot/zImage arch/arm/boot/dts/omap4-panda-es.dtb > /tmp/appended 5. Use mkimage to produce the appended device tree uImage $ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \ -n "Linux" -d /tmp/appended /tmp/uImage Signed-off-by: Tony Lindgren <tony@atomide.com --- arch/arm/mach-omap2/Kconfig | 8 - arch/arm/mach-omap2/Makefile | 1 arch/arm/mach-omap2/board-omap4panda.c | 455 -------------------------------- 3 files changed, 464 deletions(-) delete mode 100644 arch/arm/mach-omap2/board-omap4panda.c
