[PATCH 00/18] Drop remaining pdata for am335x and use genpd

[PATCH 00/18] Drop remaining pdata for am335x and use genpd

[Tony Lindgren]

Hi all,

With the related driver changes, we can now drop the remaining platform
data for am335x for v5.11 merge window and probe using device tree data
and genpd instead.

Regards,

Tony

[PATCH 02/18] ARM: dts: Configure also interconnect clocks for am3 system timers

[Tony Lindgren]

We now manage clocksource and clockevent clocks directly with
timer-ti-dm-systimer. In order to use genpd with prm_omap,
GENPD_FLAG_PM_CLK and simple-pm-bus, we need to keep the system
timer related interconnect clocks enabled until clocksource suspend
is done.

[PATCH 03/18] ARM: OMAP2+: Drop legacy platform data for am3 control module

[Tony Lindgren]

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.

To drop the legacy platform data for am3 control module, we need
to configure the missing functional clock and tag the module to
not idle as platform data also had it configured with
HWMOD_INIT_NO_IDLE.

We can now probe devices with device tree only configuration using

Note that we no longer need ti,no-reset-on-init as the rstctrl resets
are properly handled by the reset driver and claimed by the RTC driver.
And we need to squash together the module ranges for driver compability.

[PATCH 12/18] ARM: OMAP2+: Drop legacy platform data for am3 mpuss

[Tony Lindgren]

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.

As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

[PATCH 18/18] ARM: OMAP2+: Build hwmod related code as needed

[Tony Lindgren]

If we have only am3 selected, there's no need to build the
hwmod related code as we are probing devices with device tree
data.

Strange, bbb has been working for me with NFSroot, that's with
omap2plus_defconfig. Care to send your .config so I can give it a
try tomorrow?

Just tried omap2plus_defconfig, and it also hangs during boot.

Hmm and I just tried and bbb still boots NFSroot for me at commit
5a230524f879 ("ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup").

Not sure why your bbb would produce all the deferred probe while mine
won't.

However, I've noticed that we need the following patch on omap4/5 and
dra7 when playing with updating them to use genpd.

Maybe this also fixes your boot issue if you can give it a try?

Tony

I do also experience the boot problem described by Geert.

Head being:
b0625afe305253d0831af9289b37c906c18a781b
ARM: OMAP2+: Drop legacy platform data for am3 mpuss

=> BBB boots Ok.

Head being:
5a230524f87926f24d637fe62fd689f7f86f5036
ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup

=> BBB boot fails. (I don't have any debug parameters => last thing I
see in UART is from uBoot:

Bytes transferred = 89849 (15ef9 hex)
Kernel image @ 0x81000000 [ 0x000000 - 0x928200 ]
## Flattened Device Tree blob at 82000000
   Booting using the fdt blob at 0x82000000
   Using Device Tree in place at 82000000, end 82018ef8

Starting kernel ...

5a230524f87926f24d637fe62fd689f7f86f5036 + this patch 
ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup (+ patch)
Boot still fails for me.

Please note - my environment takes the intermediate build result file:
arch/arm/boot/dts/.am335x-boneblack.dtb.dts.tmp

and compiles this with '-@' to allow further overlays.

Looking at the .config Geert sent me, at least CONFIG_SIMPLE_PM_BUS=y
is now needed, and probably should be selected or default y for omaps.

Adding that removes the -512 errors at least that I started seeing with
Geert's config too.

Can you guys check if adding CONFIG_SIMPLE_PM_BUS=y fixes the problem?

Regards,

Tony

After enabling CONFIG_SIMPLE_PM_BUS
5a230524f87926f24d637fe62fd689f7f86f5036
ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup


boots Ok :) Sounds like it should be enabled on BBB by default.

Thanks, that did the trick!
Sorry for not realizing that myself.

OK thanks for testing, will send out a patch soon with both of you
in Cc.
