[PATCH] ARM: tegra: remove pinmux setup from Tegra124 boards

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

The defined mechanism for programming the Tegra pinmux is to perform all
of the following at once:

- Set the CLAMP_INPUTS_WHEN_TRISTATED PMC register bit.
- Set up any GPIO pins to their "initial" state.
- Program all pinmux settings in one go.

Other methods such as:

- Not setting CLAMP_INPUTS_WHEN_TRISTATED.
- Not setting GPIOs to their "initial" state before programming the
  pinmux settings of the related pin, in particular the mux function.
- Not programming the entire pinmux at once, in order to avoid
  possible conflicting settings.

... are not qualified or supported by NVIDIA ASIC/syseng. They could
cause glitches or undesired output levels on some pins, or controller
malfunction.

While we've been getting away with doing something different on many
Tegra boards without issue, I believe we've just been getting lucky.
I'd like to switch all Tegra124 systems to the correct scheme now so
they provide the right example to follow, and require that any new
boards we support upstream work in the same fashion.

While it would be nice to update boards containing older SoCs for
consistency, I don't anticipate doing so. It's too much churn to change
at this time. At least with all Tegra124 boards converted, the most
recent boards provide the correct example.

Since the bootloader needs to reprogram the pinmux to access certain
peripherals, it must program the entire pinmux due to the supported
rules above. As such, there is no need to program any part of the pinmux
from the kernel, unless dynamic pinmuxing is used. Hence, this change
removes all static pinmux from all Tegra124 board DTs.

The following U-Boot commits fully initialize the pinmux:

Jetson TK1: 4ff213b8e478 ARM: tegra: clamp inputs on Jetson TK1

Venice2: 3365479ce78a ARM: tegra: Venice2 pinmux spreadsheet updates

Without those commits, the only fallout I see from this change is that
HDMI on Venice2 no longer works. Given the very small user-base of this
platform, I feel that requiring a bootloader update is reasonable.

Re: [PATCH] ARM: tegra: remove pinmux setup from Tegra124 boards

[Lucas Stach]

Hi Stephen,

sorry for getting on this late, I completely missed this and only now
stumbled upon this.

I'm not really fond of this change. The barebox bootloader completely
probes itself from DT, including the pinmux. We try to stay as close as
possible to the upstream kernel DTs and only introduce minimal changes.
Removing the pinmux from the DTS will completely break barebox, as we
don't have any static pinmux tables there.

In order to not break the bootloader use-case I strongly advocate to
keep the static pinmux in the DT. Can't we just rename the the state to
something like "initial", so Linux won't try to set it by default? This
way we could still keep the information in the DT, while being able to
say "if you are going to program the initial pinmux state you need to
follow the sequence defined by NVIDIA syseng".

This obviously would make the naming of the state part of the binding,
but I think this may be acceptable.

Regards,
Lucas

Probing bootloaders from DT seems like a huge mistake to me, but that's 
probably a separate discussion.

The pinmux generator scripts spit out DT, so you can easily generate a 
DT representation of the board pinmux, and add that to the DT file in 
Barebox. See https://github.com/NVIDIA/tegra-pinmux-scripts.

That doesn't seem like a good idea. There's no reason for the DT to 
contain data that we know has no use.

Bringing DT into the bootloader was one the single most important
things for productivity we ever did.
On i.MX (the best supported arch in Barebox) it has brought down bringup
time for boards already supported by Linux to a few hours and enables us
to share effort spent for bootloader development on new boards with
later Linux development. Writing a single DT description for the
hardware to bring up the bootloader greatly reduces the time needed to
bring up Linux later on.

I could do that, but...

Just because the DTS are still located in the kernel tree doesn't mean
the kernel is the only user. DT is meant to be a hardware description.
IMHO knowing that the kernel isn't using some information contained in
there is no argument for omitting the info.

Linus, what do you think of Lucas's proposal?

As background, the Tegra HW design implies that all initial pinmux setup 
should be applied one time early during boot before peripherals are 
used. That means it should happen early in boot code, not once an OS 
like Linux has been loaded, since loading the OS requires use of at 
least some peripheral(s). Hence, there's no point the kernel re-applying 
the same configuration.

I had suggested (in this patch) removing the pinmux completely from the 
DT, since no OS should need it. However, the Barebox bootloader is 
configured via DT, and so wants to keep the pinmux configuration in the 
DT, rather than embedding the pinmux tables into the bootloader's board 
support code. Lucas has suggested simply changing the pinmux state name 
in the DT so that the kernel won't apply the pinmux configuration yet 
it's still there for the bootloader to use if it wants.

I'd suggest "boot" rather than "initial" myself for the new state name, 
but that's just bike-shedding.

I guess we say the DTs should be neutral to OS, whether they should
be neutral to the use case for boot loaders is another question, but
I think the more info is in the DT, the better actually as it avoids spreading
relevant information across places where it's hard-coded.

I'm game for "boot".
