[U-Boot] [PATCH V3 2/2] core: device: use dev_power_domain_on

[Peng Fan]

When multiple power domains attached to a device, need power on
them all, so use dev_power_domain_on to do that.

[U-Boot] [PATCH V3 2/2] core: device: use dev_power_domain_on

[Oliver Graute]

Hello Peng,

this patch broke my u-boot on a IMX8 QM ROM 7720a1 board.

f0cc4eae9a1702a768817ea25d9f23cece69d021

I bisect it and that is the first broken commit. The commits before are
working fine.

I tried to remove your changes but then  I run into this errrors:

sc_rm_get_memreg_info: mr:38 res:22
Memreg get info failed, -110
mu_hal_sendmsg timeout
sc_rm_is_memreg_owned: mr:39 res:21
sc_rm_is_memreg_owned: mr:39 res:21
mu_hal_sendmsg timeout

Some clue whats wrong here? Do I need to adapt my imx8qm board file?

Best regards,

Oliver

Update your scfw/atf and they try again.

correct ATF/SCFW versions.

Does it boot if you use the imx_4.19.35_1.0.0 ATF branch?

Unfortunately, not. I checked out imx-atf in that branch. Build it with:

make PLAT=imx8qm bl31

copied the resulting bl31.bin into my u-boot folder and rebuild that.

But the imx8qm board is not booting with the resulting u-boot.

do I need a new scfw from my vendor?

Oliver

FYI,

I do face the same boot issues on colibri-imx8qxp_defconfig ,
In my case using imx_4.19.35_1.0.0 TF-A(ATF) doesn't help too.

Bi-secting also points to this commit.

As we are close to the release, I think we should do a revert.

Could you please send a revert patch to fix the regression?

Sure, will do tomorrow morning asap.Btw, there is also a regression in MMC
subsystem (currently AFK, will look into it and provide more details also
tomorrow), probably the same as explained in the "i.MX8MM-EVK Boot failure"
thread.

What is the MMC error you see?

It seems we need an equivalent of kernelci.org in U-Boot. We are
seeing lots of regression and we are close to the release.

No, the previous method not check return value of power domain on, so
even if fails, it still continue. However this patch will check the return
value, if power fails, if will return failure. I think this is the issue,
you need check which power domain fails in your side.
Revert this patch is not good.

Thanks,
Peng.

BTW, we are currently working (internally in Toradex) on LAVA-based
solution for testing both U-boot (hopefully Linaro finally added support for
testing bootloaders, [1]) and Linux kernel.

We plan to automate testing of both BSP downstream and mainline
trees, so it makes sense to configure (that's still under discussion)
some interaction with ML, for example sending notification about
regressions/automatic bi-secting results (analog of
syzbot emails in LKML) etc.

If you have any ideas - we're open to any suggestions/input.

Sorry for the noise about mmc, there was a bug introduced in
c20851b3d8("dm: pinctrl: introduce PINCONF_RECURSIVE option"), which
is already fixed in 44510daea4("dm: pinctrl: fix for introduce
PINCONF_RECURSIVE option")

Does it also happen with 2020.01-rc5?

Looks like a different MMC issue than the one we saw with i.MX8MM EVK.

It would be very helpful to have regression notifications in the
U-Boot mailing lists.

Did you made some progress here?

I tried this combination but without success for the imx8qm_rom_7720:

u-boot 2020.01
imx-atf imx_4.19.35_1.1.0
imx-sc-firmware-1.2.7.1.bin
imx-seco-2.3.1.bin

Which latest combination is vaild for the imx8qm_mek board?

Best Regards,

Oliver
