Add HS-USB device tree support for R8A7790/Lager board

Hello.

Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20141007-v3.17' tag. Here we add the HS-USB device tree support on the R8A7790/Lager reference board. The patchset requires the USB PHY driver (already merged by Kishon and Greg) and the generic PHY support patches for the HS-USB driver posted by Yoshihiro Shimoda in order to work...

[1/2] ARM: shmobile: r8a7790: add HS-USB device node [2/2] ARM: shmobile: lager: enable HS-USB

WBR, Sergei

From: Yoshihiro Shimoda <[email protected]>

Define the R8A7790 generic part of the HS-USB device node. It is up to the board file to enable the device.

---
Changes in version 3:
- uppercased "arm" in the summary;
- added changelog.

From: Yoshihiro Shimoda <[email protected]>

Enable HS-USB device for the Lager board, defining the GPIO that the driver should check when probing. Since this board doesn't have the OTG ID pin, we assume that GP5_18 (USB0_PWEN) is an ID pin because it is 1 when the SW5 is in position 2-3 (meaning USB function) and 0 in other positions.

Note that there will be pinctrl-related error messages if both internal PCI and HS-USB drivers are enabled but they should be just ignored.

[Sergei: added pin node and prop, moved device node, fixed summary, supplemented changelog]

---
Changes in version 4:
- fixed pin node name;
- moved pin node before USB0's one.

Changes in version 3:
- added pin function/group and the pinctrl-related prop;
- moved the HS-USB node to precede the USB PHY node;
- uppercased "arm" in the summary;
- supplemented changelog.

Now that v3.18-rc1 is present in my devel branch should I queue-up these patches? If so, please rebase them on renesas-devel-20141024-v3.18-rc1

Hi Simon-san,

Since the first patch set was made from me, I will rebase this.

Best regards,
Yoshihiro Shimoda

Define the R8A7794 generic part of the HS-USB device node. It is up to the board file to enable the device.

Thanks, I have queued this up.

Enable HS-USB device for the Porter board, defining the GPIO that the driver should check when probing (which is the ID output from MAX3355 OTG chip).

Note that there will be pinctrl-related error messages if both internal PCI and HS-USB drivers are enabled but they should be just ignored.

This patch is analogous to the commit 6f4f7156e0e6 (ARM: shmobile:
henninger: enable HS-USB) as there are no differences between the boards in this respect.

I took the liberty of tweaking the changelog to address a complaint made by Mr. Check Patch.

Hello.

Which means I forgot to run it again. Sorry about that. :-<

Keep forgetting about the now enforced quotes...

Define the Porter board dependent part of the CAN0 device node.

Hello.

Actually, I was going to check this patch WRT the DU channels used, given
Laurent's remark. OK, I will just send an incremental patch if needed.

MBR, Sergei

Thanks and sorry for being a bit hasty.

Define the SILK board dependent part of the DU device node. Add the device nodes for the Analog Devices ADV7511W HDMI transmitter (connected to DU0) and ADV7123 video DAC (connected to DU1). Add the necessary subnodes to interconnect DU, HDMI/VDAC devices, and HDMI/VGA connectors.

Thanks, I have queued this up for v4.6 after updating the subject with s/shmobile/dts/ to reflect a request made from the ARM SoC maintainers regarding prefixes for DT patches.

Define the Porter board dependent part of the R8A7791 sound device node. Add device node for Asahi Kasei AK4642 stereo codec to the I2C2 bus. Add the "simple-audio-card" device node to interconnect the SoC sound device and the codec.

This is no a big deal, but according to my schematic, porter is using JP3, not SW3, but no one cares ;P

Thanks, I have queued this up.

Sergei, please feel free to provide a follow-up patch to address this.

Hello.

Thank you. I forgot to mention that the patch was based on your work... :-/

Indeed, sorry about that.

MBR, Sergei

Now that Maxim Integrated MAX3355 'extcon' driver and device tree bindings are upstream along with the 'extcon' hook in the Renesas USBHS driver, we can add MAX3355 device node to the Porter device tree and properly refer to it from the USBHS node instead of using "renesas,enable-gpio" property which only allowed checking the USB ID pin at the driver probe time; now this pin's state can be monitored dynamically!

Hi,

I tested this patch on Porter, but interrupt of "usb-otg" didn't happened even if I connected/disconnected a usb convert cable (usb micro-ab to A).
Remarks: I confirmed that the usb convert cable worked correctly on other board.

Do I need other settings for this?

Hello.

I guess I have the same cable and IRQs do happen for me when I connect and
disconnect it (as it should be).

No evident answer to that, your logs show that MAX3355 driver was enabled...

I guess these states doesn't change even if you insert your cable?
They also do change for me.

MBR, Sergei

No, I have mini-AB connector here and hence my cable is mini-AB to A.

MBR, Sergei

Hi,

I checked Porter specification and then I found 2 specifications exist...
Porter "B" : mini AB connecter and Max3355 is on the board.
Porter "C" : micro AB connect and Max3355 is not on the board. (Select host/peripheral by a jumper.)

I guess that your current target is "B".
If so, I think this patch is acceptable.

Best regards,
Yoshihiro Shimoda

Hello.

I've looked thru my schematics files and found 3: Rev. 1.1 Update Version
2, "PORTER_2" Rev. 3.0 Preliminary, and "PORTER_C" Rev. 3.0 Release version! I'm not sure which of the last 2 should be considered final...

Yeah, seeing JP13 in the PORTER_C schematics.

If not earlier. It actually has "Henninger B REV2" printed on it and
"Porter PCB 1 R3" on a pasted sticker.

I'm not so sure now...

MBR, Sergei

Now I've found 5 versions of the Porter schematics... :-)

My boss told me PORTER_C is a final version, so this patch isn't needed.
But then another patch is needed instead: to remove "renesas,enable-gpio" prop from the HS-USB device node...

MBR, Sergei

I am marking this patch as "Rejected" in patchwork. If changes are required in this area please either resubmit this patch or post a different one.

Thanks.

Posted a different one on Saturday.

MBR, Sergei

Define the SILK board dependent part of the R8A7794 sound device node. Add device node for Asahi Kasei AK4643 stereo codec to the I2C1 bus. Add the "simple-audio-card" device node to interconnect the SoC sound device and the codec.

This patch is based on the commit 493b4da7c10c ("ARM: dts: porter: add sound support").

---
This patch is against the 'renesas-devel-20160209-v4.5-rc3' tag of Simon Horman's 'renesas.git' repo. It depends on the 5 R8A7794 sound support patches

in posted earlier this week  in order to build and the R8A7794 PFC driver
patches posted yesterday in  order  for  the pins to be properly configured
(but works without the pins  configured  too)...

Hi

This patch doesn't use SRC, and it is no problem.
We need fixup src.c driver for r8a7794 because it lacks some SRCs.

When finishing the Porter sound support patch, I managed to call the JP3 jumper SW3 in the comment. Fix this along with (also miscalled) jumper positions...

Hi

Thanks, I have queued this up.

In the final versions of the Porter board (called "PORTER_C") Renesas decided to get rid of the Maxim Integrated MAX3355 OTG chip and didn't add any other provision to differ the host/gadget mode, so we'll have to remove no longer valid "renesas,enable-gpio" property from the HS-USB device node. Hopefully, the earlier revisions of the board were never seen in the wild...

Hi Sergei,

sorry for the extended delay. I have queued this up as a fix for v4.5.

Add the (previously omitted) DU pin data to the SILK board's device tree.

Simon, this patch seems stuck while the PFC driver patch hit Linus' tree
long ago. :-(
