[PATCH 00/14] arm64: dts: freescale: Add support for the GOcontroll Moduline Display

[Maud Spierings via B4 Relay]

Add inital support for 2 variants of the Moduline Display controller.
This system is powered by the Ka-Ro Electronics tx8p-ml81 COM, which
features an imx8mp SoC.

[PATCH 05/14] dt-bindings: trivial-devices: add GOcontroll Moduline IO modules

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

The main point of the Moduline series of embedded controllers is its
ecosystem of IO modules, these currently are operated through the spidev
interface. Ideally there will be a full dedicated driver in the future.

Add the gocontroll moduline-module-slot device to enable the required
spidev interface.

I couldn't find anything about SPI for GOcontroll Moduline. Can you 
point me to what this hardware looks like. Based on what I did find, 
this seems incomplete and not likely a trivial device.

I'll give some more details, if there is a v2 of this patch I will also
add more information in the commit message.

The module slots have a number of pins, a lot of them currently unused as
they have not found a function yet, this is very much still a developing
product. The currently used interfaces to the SoC are:
1. SPI bus as a spidev to ease developing new modules and quickly
integrate them. This is the main communication interface for control and
firmware updates.
2. A reset pin, this is/was driven with the gpio-led driver but I doubt
that would get accepted upstream so I intend to switch to the much better
suited libgpio.
3. An interrupt pin, this is currently only used in the firmware update
utility [2] to speed up the update process. Other communication is done at
a regular interval.

What is unused:
1. A potentially multi-master i2c bus between all the module slots and
the SoC
2. An SMBus alert line is shared between the modules, but not the SoC.
3. A shared line designated as a clock line, intended to in the future
aid with synchronizing modules to each other for time critical control.

current software that is used to work with the modules can be found at
[2] and [3], one of them is a Node-RED module the other is a blockset for
Matlab/Simulink generated code.

If you know a better way I could describe this in the devicetree then I
would love to know, I am always keen on learning more. As I said in the
commit message it would be nice to have an in kernel driver that would do
all the interrupt handling, firmware updating, probing but that is sadly
not in our capabilties right now.

We are hoping to eventually make this interface an open standard that
other people can integrate into their PCB's to make use of the various IO
modules. I have personally made a raspberry pi hat that can take 2 modules
for example, which I hope will in the future serve as an open source
reference design. It is not open right now though.

reset-gpios is not in trivial devices, so that's already a hint you
cannot use this binding.

You need dedicated binding where you describe entire device, entire
hardware, not what your driver supports in current release.

I see now that I also forgot the patch that adds this compatible to the
spidev driver. Didn't check for the spidevs in testing I guess.

Could I write bindings for this device, and then add the compatible to the
spidev driver for now? So it probes that driver, and then later when there
is a driver remove the compatible there and keep it only in the purpose
built driver?

So I'll write gocontroll,moduline-module-slot.yaml, don't quite know where
that would go. Define all these attributes in there and then add the 
compatible to drivers/spi/spidev.c

Is that okay?

Kind regards,
Maud

Yes. Bindings are forever, but drivers change. ;)

Perhaps put it in connector/ as this looks a bit like a connector. Do 
you envision DT overlays for the IO modules? Or modules don't have 
sub-devices you need to describe? There's some effort to on connector 
bindings (for mikrobus in particular) in order to de-couple host 
buses/signals from the modules (i.e. so a DT overlay can be applied to 
any DT defining the connector).

Okay that is great to hear, I was afraid I was going to have to drop
support for the foreseeable future. I'll get to work on those for v2.

I don't envision overlays coming in to play here, everything should be
probed by the driver. Just needs the socket definition. The IO module
bootloader will communicate what type of module it is and what firmware
version it is running. Modules can be swapped very easily between boot
cycles if the lid is off, it would be very annoying to then have to mess
with the devicetrees. For most of our customers that might be too
complicated. I am still thinking on how to keep the ecosystem open for
others to develop their own IO modules, but I'll figure that out when we
get there.

Kind regards,
Maud

[PATCH 06/14] arm64: dts: imx8mp: Add pinctrl config definitions

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

Currently to configure each IOMUXC_SW_PAD_CTL_PAD the raw value of this
register is written in the dts, these values are not obvious. Add defines
which describe the fields of this register which can be or-ed together to
produce readable settings.

[PATCH 09/14] MAINTAINERS: add maintainer for the Ka-Ro tx8p-ml81 COM module

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

Add GOcontroll as unofficial maintainers of the Ka-Ro tx8p-ml81 COM
module bindings.

This support is not officially done by Ka-Ro electronics, if they at
some point will supporting mainline, this should be changed to them.

[PATCH 12/14] arm64: dts: freescale: Add the GOcontroll Moduline Display baseboard

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

The Moduline Display platform is a part of the wider GOcontroll Moduline
ecosystem. These are embedded controllers that focus on modularity with
their swappable IO modules.

The base Moduline Display board includes a board-to-board connector with
various busses to enable adding new display types required by the
application. It includes 2 Moduline IO module slots, a simple mono
codec/amplifier, a four channel adc, 2 CAN busses, an RTC and optional
wifi/bluetooth.

busses to the display adapter include:
- 4 lane LVDS
- 4 lane MIPI-DSI
- 4 lane MIPI-CSI
- HDMI 2.0a
- USB 2.0
- I2S
- I2C
- SPI

Also a couple of GPIO and PWM pins for controlling various ICs on the
display adapter board.

[PATCH 13/14] arm64: dts: freescale: Add the BOE av101hdt-a10 variant of the Moduline Display

[Maud Spierings via B4 Relay]

From: Maud Spierings <maudspierings@gocontroll.com>

Add the BOE av101hdt-a10 variant of the Moduline Display, this variant
comes with a 10.1 1280x720 display with a touchscreen (not working in
mainline).

Signed-off-by: Maud Spierings <maudspierings@gocontroll.com>

---
Currently the backlight driver is not available, this will be upstreamed
in a future patch series. It is a Maxim max25014atg.

The touchscreen has a Cypress CYAT81658-64AS48 controller which as far as
I know is not supported upstream, the driver we currently use for this is
a mess and I doubt we will be able to get it in an upstreamable state.
