Add support for CompuLab CM-SOM-AM57X board.
CL-SOM-AM57x is a miniature System-on-Module (SoM) based on
TI Sitara AM57x ARM Cortex-A15 System-on-Chip family.
https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/
Add basic DT support for standalone module (without a carrier board):
* Memory configuration
* Heartbeat led
* I2C1 bus
* PMIC
* SATA

I think if you like to enable LPAE, the format might look a little
different..

Generic comment: As per requirements of the SoC -> all pinctrl must be
done in bootloader. this was a recommendation that came in too late
for TI platforms that got introduced in upstream, but that cleanup
should eventually take place as well.

Also See: https://patchwork.kernel.org/patch/7596541/ ->
Documentation/devicetree/bindings/i2c/i2c.txt -> since you seem to
have a PMIC with power button, you might be able to get wakeup source
also there.

Assuming powerhold signal and BOOT0,1 is proper here, else poweroff
will never work.

for eventual UHS mode support, it is recommended to keep VDD_SD
separate from VDDSHV8. many of TI evms also suffer from this issue :(

Happy to see this is already split up. you might want to document
which PHYs are supplied by PHYA/B in comments for future reference
instead of having to dig through schematics to figure that out..

as per data sheet:
"VD_RTC can optionally be tied to VD_CORE and operate at the VD_CORE
AVS voltages."
I assume that is not the case here.

All SoC VDDAs must be always-on.

We would like to have a basic HW support in the mainline. It might be
enhanced later, once we get to work on LPAE stuff.

Please, could you provide a reference to those recommendations.
Do you mean pinctrl for PMIC pins only?

Do you mean just adding "wakeup-source" property?
According to Documentation/devicetree/bindings/i2c/i2c.txt the primary
interrupt will be used as wakeup interrupt.

You might want to ask your TI support contact for IODelay
recommendations. TRM mentions that pinmuxing must be performed under IO
isolation. There are silicon constraints in DRA7/AM57xx family, which
were not present previously.

I think you might have to describe a "wakeup" interrupt -> which will be
similar in description to the one you used to describe uart wakeup
capability.

well, if poweroff command does not completely power off your board, you
may want to investigate further. overall, the better circuit
configuration is the X15 configuration:
https://github.com/beagleboard/beagleboard-x15/blob/master/BeagleBoard-X15_RevA2.pdf
Pay close attention to the PMIC GPIO_&/POWERHOLD signal. Also notice the
extra reset circuit involved.
Again, a topic that you should probably discuss with your TI support
contact person.

Ok. I understand. This might take time...
Since we'd like to have this in for 4.5, what would you recommend?
Should I drop the muxes from this patch set? All the muxes?
Or should we merge this (as it works correctly) in our tests and check
on this later after investigation with TI?
Also, in theory, there might be pins shared between two or more
different functionalities and remuxed during runtime.
Can this kind of thing be supported on AM57x?

Ok. Thanks!
Well, we are not there yet.
I think it would be better to work this out when I will work on the
suspend/resume.

Ok. Thanks for the explanation! Indeed it does not currently work.

This is why I suggested to talk and confirm with TI support contact on
this. I understand the motivation of SoM concept, but this requires some
careful designing around.

I think what is meant here is the cell sizes should be 2 instead of 1.
You can do that independent of LPAE support. I would expect the base SOC
dtsi file to set the cell sizes correctly though.

Add support for CompuLab CM-SOM-AM57X board.
CL-SOM-AM57x is a miniature System-on-Module (SoM) based on
TI Sitara AM57x ARM Cortex-A15 System-on-Chip family.
https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/
Add basic DT support for standalone module (without a carrier board):
* Memory configuration
* Heartbeat led
* I2C1 bus
* PMIC
* SATA
Signed-off-by: Dmitry Lifshitz <lifshitz@compulab.co.il>
Acked-by: Igor Grinberg <grinberg@compulab.co.il>
---
v2:
* Fixed voltages (for OPP_HIGH) for VDD_GPU, VDD_IVA, VDD_DSPEVE
* Added comments for VDDA_1V8_PHYA/B
* Add "regulator-always-on" property for ldousb_reg

Can you please put these into dra7-tps659038-common.dtsi so we don't have
multiple copies of it? Then make other boards include that..
That allows to set them up as real controllable regulators instead of all
this silly "regulator-always-on" stuff that has been going on since omap4 :)

Tony

It might looks the same set of regulators for multiple boards,
but it is not. Each board may apply its own regulators usage scheme, and
this is our case (as compared to am57xx-beagle-x15.dts).
For the best of my knowledge, it used to be in a common *.dtsi file (at
least in early OMAP5 DT support in TI kernel tree), but then I found
that PMIC registration had been moved to the boards DT files.

Have you actually looked at how much of the implementation is same across
the omap5 boards? My guess is that a whole lot is same.. See for example
omap5-board-common.dtsi.

Tony

Unfortunately with DRA7 / AM57xx:
at least 2 different PMICs -> DRA74/DRA72 evms.
even across similar PMIC usage, different voltage rail usage accross
evms: DRA74evm, x15/GPEVM, AM571x-IDK/AM572x-IDK -> they are not
necessarily compatible.
Example: some of them have Ganged voltage rail, others dont - few others
are mixed. if you are trying to get common regulator usage -> it is
kinda pretty hard given the freedom board designers are being given by
TI.. OMAP5 was more controlled in terms of what specific configuration
the board designers had to follow. that is no longer the case for
DRA7/AM57 platforms. just my 2 cents here.

OK thanks for checking. Best to wait a bit on that then until we have
more common patterns.

SBC-AM57x is a single board computer designed for industrial and
embedded applications. It is based on the Texas Instruments Sitara AM57x
system-on-chip family. SBC-AM57x is implemented with the CL-SOM-AM57x
computer-on-module providing most of the functions, and SB-SOM-AM57x
carrier board providing additional peripheral functions and connectors.

https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/
Add basic board support, including UART3, used as a serial console.

Add HDMI connector node without a valid input endpoint.
CompuLab SB-SOM is a carrier board, hence the endpoint
should be added in the board DT with a valid HDMI output.

SBC-AM57X boards.
CL-SOM-AM57x is a miniature System-on-Module (SoM) based on
TI Sitara AM57x ARM Cortex-A15 System-on-Chip family.
SBC-AM57x is a single board computer, implemented with the
CL-SOM-AM57x computer-on-module providing most of the functions,
and SB-SOM-AM57x carrier board providing additional peripheral
functions and connectors.
The SBC-AM57x has the following features:
CPU: Texas Instruments Sitara AM5728 dual-core ARM Cortex-A15, 1.5GHz or
Texas Instruments Sitara AM5718 single-core ARM Cortex-A15, 1.5GHz
RAM: DDR3, 512MB ? 4GB
Storage: NAND flash, 512MB - 1GB or eMMC flash, 4GB - 32GB
SPI-flash 2MB
Ethernet: Up to 2x 10/100/1000Mbps Ethernet ports (MAC+PHY)
WiFi/BT: 802.11b/g/n WiFi interface (TI WiLink 8 WL1801 chipset) or
Dual-band 2x2 802.11a/b/g/n WiFi interface (TI WiLink 8 WL1837 chipset)
Analog Audio: Audio codec with stereo output, stereo input and microphone support

SBC-AM57x is a single board computer designed for industrial and
embedded applications. It is based on the Texas Instruments Sitara AM57x
system-on-chip family. SBC-AM57x is implemented with the CL-SOM-AM57x
computer-on-module providing most of the functions, and SB-SOM-AM57x
carrier board providing additional peripheral functions and connectors.

https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/
Add basic board support, including UART3, used as a serial console.

Add HDMI connector node without a valid input endpoint.
CompuLab SB-SOM is a carrier board, hence the endpoint
should be added in the board DT with a valid HDMI output.

ETH PHYs setup on CL-SOM-AM57X is established in U-Boot along with
bringing them out of reset. This is done by toggling GPIOs belonging
to GPIO2/3 controllers on AM57xx.
Skip resetting ETH PHYs, by adding "ti,no-reset-on-init" to GPIO2/3
controllers DT nodes.
