[PATCH v3 0/4] Add DTs for all Apple M1 (t8103) devices

[PATCH v3 0/4] Add DTs for all Apple M1 (t8103) devices

[Janne Grunau]

Hej All,

this series extends the device tree files and bindings to all current
Apple M1 devices. Specifically it adds DTs for following devices:
- MacBook Air (M1, 2020)
- Macbook Pro (13-inch, M1, 2020)
- iMac (24-inch, M1, 2021)

It also adds i2c and cd321x devices nodes. Bindings and code changes for
those were merged for 5.16 without adding devices to the device tree.
Patches are include in a single series for dependencies

Changes since v2:
 - split i2c and cd321x changes into 2 commit
 - add i2c4 used by MacBooc Pros (j293, 13-inch, M1, 2020)
 - add hpm2 and hpm3 for the additional USB-C ports on j456 iMac
   (24-inch, M1, 2021) models

Series depends for functionality and dtbs verification on
"[PATCH 0/3] Apple Arm patform device tree and bindings fixes".

thanks,
Janne

[PATCH v3 3/4] arm64: dts: apple: t8103: Add i2c nodes

[Janne Grunau]

Apple M1 has at least 5 i2c controllers. i2c0, i2c1 and i2c3 are used
on all M1 Mac devices. The 2020 Mac Mini uses i2c2 and the 13-inch
MacBook Pro uses i2c2 and i2c4.

[PATCH v3 4/4] arm64: dts: apple: t8103: Add cd321x nodes

[Janne Grunau]

All M1 Mac devices have 2 SoC connected USB-C ports and use cd321x USB
type C port switch and power deliver controllers. I2c bus and adresses
configuration are for all devices equal.
The iMac (24-inch, 2021) has a configuration with 2 additional USB-C
ports (j456) using two addiotional cd321x controllers.

Please put these before serial0; I want to keep the nodes sorted by address.

On further testing: i2c3 is not used on the 1GbE variant of j274. iBoot 
actually kills the node entirely. The interesting thing is it doesn't 
work; it times out probe transactions. I suspect iBoot does not enable 
its clock or something like that.

I'll poke around this on IRC, but a priori we probably need m1n1 code to 
kill this node when the ADT doesn't have it. Maybe I should generalize 
the dwc3 killing code...

No need for clock-names in these nodes. The schema only allows a single clock
anyway.

I know that the tps example in the binding uses tps6598x as the node name
but I think that these names are usually more general. Maybe usb-pd@3b
instead which is used in arch/arm64/boot/dts/freescale/imx8mq-librem5.dtsi
and reflects the function of this device.

With that fixed:

I know that the tps example in the binding uses tps6598x as the node name
but I think that these names are usually more general. Maybe usb-pd@3b
instead which is used in arch/arm64/boot/dts/freescale/imx8mq-librem5.dtsi
and reflects the function of this device.

Did that as of m1n1 be7ff3a, so we're good now :)

For those following along in the list: the reason why i2c3 was getting 
stuck is because it seems the unused bus is weakly pulled low on these 
machines, which jams it. Setting the GPIO pull mode to pull-up makes it 
work as an empty bus, but let's just not instantiate at all in this 
case. m1n1 now checks the Apple DT and sets any FDT i2c devices that are 
not present in it to disabled.

That looks like some power saving attempt.

I suppose that means that even i2c buses that are in use
could be weakly pulled low when suspending the system
and maybe even inbetween transactions to save some
leak current.

Pulled up vs. down dosn't really result in better power savings; neither 
state will necessarily have more leakage. I think it's just that the 
pins are completely disconnected, and there's some very minor leakage to 
ground (megaohms will do) that ends up pulling them down.

Pulling down an I2C bus between transactions is not legal; the idle 
state has to be high.

Apple are actually not very good at configuring GPIOs for power saving; 
e.g. the I/Os for that unused i2c bus still have their input buffers 
turned on, which is a waste of power. If they wanted to save the 
smallest drop of power they'd turn that off. But the effect of this is 
so trivial it probably makes no difference in the context of a laptop, 
nevermind a desktop like the Mac Mini.

Hm that's true. The saying is that 99% is the backlight, the remaining 1% isn't
so significant after that.

From watching a USB power meter plugged into the MacBook Air, I can say the backlight is about 70% :-)

Then again, the new MBPs have LED matrix backlit screens... so suddenly dark themes are more efficient again! I should measure that one, see how much power changing themes saves.

there is already a v4 with Sven's comments addressed at

https://lore.kernel.org/linux-arm-kernel/20211123224926.7722-1-j@jannau.net/

Jean-Marc Ranger notified me off-list of a typo in "arm64: dts: apple: 
t8103: Add cd321x nodes" commit messages: 'addiotional'.

I don't think it's worth spinning up a v5 for fixing that typo.

thanks,

Janne

Oh whoops, I think I mixed that one up with this one when scrolling 
through email and thought they were the same series. Was just catching 
up on email and it hadn't hit me yet... thanks for pointing it out.
