cover ARM: dts: Better support for Gumstix Overo

Hello,

This series adds a number of improvements to Gumstix Overo.

Patch 1+2: fix an issue with the vendor prefix (reported long ago by Javier Martinez Canillas) Patch 3+4: add some missing pinctrl entries
Patch 5: completely turn off the PMIC on power off
Patch 6: enable the on-board Wifi
Patch 7: add the high-speed USB PHY
Patch 8: add specific timings for LAN9221 into a generic file
-> This might interest other people using the same chip, result in doubled bandwith

Patch 9: simplify omap3-tobi by using patch 8
Patch 10: add support for AT24C01 EEPROM used on expansion boards Patch 11: factorize parts common to all expansion boards Patch 12: rename omap3-tobi to omap3-overo-tobi
-> I do not know to which extent this might qualify as an API breakage,
but the new name is far better IMHO

Patch 13 to 17: add new extension boards (Palo43, Gallop43, Alto35, Chestnut43, Summit) Patch 18: add the HDMI output
-> this patch depends on Tomi Valkeinen's DT binding for OMAPDSS, which is
not yet merged, so this patch will have to wait

The patches 13 to 17 are based on the hardware schematics and compile-tested, as I do not have the necessary hardware (anyone willing to send me some boards ? :-) We are mainly missing the support for the various LCDs, the accelerometer + probably other small things.

This series is based on Tony's omap-for-v3.14/dt branch + work from Tomi [1] for the patch 18.

Benoit: I guess that I am too late for the 3.14... ?

Regards,

Florian

PATCH 5/18 ARM: dts: omap3-overo: Use complete poweroff

In reply to Florian Vaussard

Currently, the TWL4030 PMIC does not completely poweroff the processor. Commit b0fc1da4d0359d3cce8f12e0f014aed0704ae202 introduced the necessary binding to do this, so use it.

PATCH 6/18 ARM: dts: omap3-overo: Enable MMC2

In reply to Florian Vaussard

MMC2 is used by the on-board WiFi module populated on some boards (based on Marvell Libertas 8688 SDIO).

Note: currently WiFi only works on cold boot, as the module is not properly reset (missing binding for the GPIO reset).

Have you looked at commit 0e9fd777 ("ARM: dts: omap3-igep: Add support for LBEE1USJYC WiFi connected to SDIO") ?

If I remember correctly the LBEE1USJYC Wifi/BT combo module is basically a Marvell Libertas 8688 Wlan and Enric got soft reset working too by adding a GPIO property to the regulator for the reset GPIO.

Hope it helps,

Many thanks for the pointer. In the initial version, I had a regulator like you. But now I doubt if it was correctly added to the MMC node, which could be why it was not working... I will try again.

Thanks for your help!

Thank you, I got it working. It is a bit messy, as I have 3 GPIOs (poweron, wifi-reset and bt-reset). As a regulator can control only one GPIO, I had to define 3 regulators, and assigning them to the vmmc, vqmmc, and vmmc_aux. I hope that a better solution will pop-up in this thread [1]. It is a pity that the previous version of the GPIO-reset controller was not merged.

PATCH 8/18 ARM: dts: omap: Add common file for SMSC9221

In reply to Florian Vaussard

Some devices (SMSC9217, SMSC9218 and SMSC9221 at least) have better timings, allowing a higher transfer speed. Create a common file with these timings.

Performance results with iperf:

- omap-gpmc-smsc911x.dtsi => 54.9 Mbps
- omap-gpmc-smsc9221.dtsi => 92.7 Mbps

cover ARM: dts: Better support for Gumstix Overo

In reply to Florian Vaussard

Hi Florian,

Hello,
This series adds a number of improvements to Gumstix Overo.

Thanks for that nice series.

Quoted 21 lines

Patch 1+2: fix an issue with the vendor prefix (reported long ago by Javier Martinez Canillas) Patch 3+4: add some missing pinctrl entries
Patch 5: completely turn off the PMIC on power off
Patch 6: enable the on-board Wifi
Patch 7: add the high-speed USB PHY
Patch 8: add specific timings for LAN9221 into a generic file
-> This might interest other people using the same chip, result in doubled bandwith
Patch 9: simplify omap3-tobi by using patch 8
Patch 10: add support for AT24C01 EEPROM used on expansion boards Patch 11: factorize parts common to all expansion boards Patch 12: rename omap3-tobi to omap3-overo-tobi
-> I do not know to which extent this might qualify as an API breakage,
but the new name is far better IMHO
Patch 13 to 17: add new extension boards (Palo43, Gallop43, Alto35, Chestnut43, Summit) Patch 18: add the HDMI output
-> this patch depends on Tomi Valkeinen's DT binding for OMAPDSS, which is
not yet merged, so this patch will have to wait

Quoted 8 lines

The patches 13 to 17 are based on the hardware schematics and compile-tested, as I do not have the necessary hardware (anyone willing to send me some boards ? :-) We are mainly missing the support for the various LCDs, the accelerometer + probably other small things.
This series is based on Tony's omap-for-v3.14/dt branch + work from Tomi [1] for the patch 18.
Benoit: I guess that I am too late for the 3.14... ?

Yeah, I think so, even my 3.14 branch is too late for 3.14 :-)

Thanks,
Benoit

Firstly: thanks!
Secondly: Could you email (ash at gumstix.com) me a wish list of boards/hardware? I'll see what I can wrangle.

Ok, I will see what I would need to advance further the DT support.

Do you have any thoughts on this? I guess that the Tobi DT is not very widely used, apart for testing purposes, but I do not want to be flamed due to an API breakage :D But I deem the new name to be worth the risk.

Yeah, I think so, even my 3.14 branch is too late for 3.14 :-)

Damn!

Ok, will go for 3.15. Anyway, I have other DT patches under the hood (OMAP4 DuoVero + my own board), so everything can go into the same release.

Best,

Florian
