[PATCH 00/11] Remove unused omap legacy code

[Tony Lindgren]

Hi all,

We can now remove quite a bit of clutter with legacy booting
gone. Basically anything with of_have_populated_dt() not set
can now go.

Regards,

Tony

[PATCH 01/11] ARM: OMAP2+: Remove unused legacy code for opp

[Tony Lindgren]

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

Note that the volt_data is still being used.

[PATCH 02/11] ARM: OMAP2+: Remove unused legacy code for timer

[Tony Lindgren]

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

[PATCH 04/11] ARM: OMAP2+: Remove unused legacy code for device init

[Tony Lindgren]

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

[PATCH 07/11] ARM: OMAP2+: Remove unused legacy code for DMA

[Tony Lindgren]

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where

[PATCH 09/11] ARM: OMAP2+: Remove unused legacy code for interconnects

[Tony Lindgren]

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

This will conflict with the changes introduced by the tusb6010 DMAengine
conversion:
https://patchwork.kernel.org/patch/9734219/

with this patch I think the omap24xx_sdma_map and omap3xxx_sdma_map can
also be removed, but we need to keep the omap24xx_sdma_dt_map for now
till we have proper DT support for tusb.

Oops forgot about that one. I'll take a look if it makes sense
to leave the braces for now to avoid a merge conflict.

We still have omap_init_sti() left there, but it's
just static inline void omap_init_sti(void) {} :)

So yeah will remove that too.

Subject: [PATCH] ARM: OMAP2+: Remove unused legacy code for device init

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

Note that omap_init_sti() won't do anything so we can
remove omap2_init_devices() as pointed out by Sebastian
Reichel <sebastian.reichel@collabora.co.uk>.

Subject: [PATCH] ARM: OMAP2+: Remove unused legacy code for device init

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

Note that omap_init_sti() won't do anything so we can
remove omap2_init_devices() as pointed out by Sebastian
Reichel <sebastian.reichel@collabora.co.uk>.

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

Let's leave the dummy omap2_system_dma_init_dev() check
in place for now to avoid a pointless merge conflict with
tusb6010 dmaengine conversion as pointed out by Peter
Ujfalusi <peter.ujfalusi@ti.com>.

Subject: [PATCH] ARM: OMAP2+: Remove unused legacy code for DMA

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

Let's leave the dummy omap2_system_dma_init_dev() check
in place for now to avoid a pointless merge conflict with
tusb6010 dmaengine conversion as pointed out by Peter
Ujfalusi <peter.ujfalusi@ti.com>.

unfortunately we still have conflict as the
https://patchwork.kernel.org/patch/9734219/
adds entries to omap24xx_sdma_map[] for - back then - valid non DT boot
support.

I have rebased and reworked my patch locally on top of your v1, but
things must go in in a certain order to avoid conflict.

The tsub conversion series in not yet in linux-next, but afaik Bin
already applied it to somewhere.
Leave the mach-omap2/dma.c cleanup for -rc1?

unfortunately we still have conflict as the
https://patchwork.kernel.org/patch/9734219/
adds entries to omap24xx_sdma_map[] for - back then - valid non DT boot
support.

I have rebased and reworked my patch locally on top of your v1, but
things must go in in a certain order to avoid conflict.

The tsub conversion series in not yet in linux-next, but afaik Bin
already applied it to somewhere.
Leave the mach-omap2/dma.c cleanup for -rc1?

Defines for L3_MODULES_MAX_LEN + L3_MODULES and most of the includes
could be dropped now.

Defines for L3_MODULES_MAX_LEN + L3_MODULES and most of the includes
could be dropped now.

Yeah I bet we have tons of unused defines now. I think
I used to have some shell script to grep for those
somewhere.

Yes, the series is in my local tree which is not public available. I
plan to send them to GregKH next week.

Turns out I misread the above and this code is still needed for omap4 PRM
interrupts, so applying a partial revert below to fix it.

Subject: [PATCH] ARM: OMAP4: Fix legacy code clean-up regression

Commit 2a26d31b1bae ("ARM: OMAP2+: Remove unused legacy code for PRM")
removed PRM platform init code that I thought is unused. Turns out omap4
still needs this code, so let's do a partial revert to add it back.

I probably missed this earlier as the comments used to say
"OMAP4+ is DT only now" for !of_have_populated_dt() to exit early and
missed the negative test. Let's not add those lines back as they are
confusing and no longer needed as we only boot in device tree mode.

Without things things can mysterious fail for i2c, for example LM75
I2C temperature sensor can stop working as the PRM interrupts won't work.

I just spent a couple of hours to tracing this and now saw, that you
already did so. Why was this not part of the pull request? :(

haha, I came up with *exactly* the same patch and then noticed
this mail when I checked for a Message-ID as reference :)

Here is the demystification:

Without this fix omap4_pmx_core and omap4_pmx_wakeup will not
register themself as interrupt controller, due to missing parent
interrupt. This means, that any device referencing an interrupt
in one of those controllers will fail their probe routine with
-EPROBE_DEFER waiting for the interrupt controller to appear.
At least for i2c this happens directly in the core, even before
calling the driver's probe routine making this look quite
mysterious.

TLDR: Fix "wakeup-source;" using devices on omap4.

Sorry I did not notice until I had sent out a pull request. I did
send a pull request for this and few other fixes on the 6th that is
still pending.
