2019-10-02ARM: dts: imx7-colibri: fix 1.8V/UHS supportStefan Agner1-1/+22
Add pinmuxing and do not specify voltage restrictions for the usdhc instance available on the modules edge connector. This allows to use SD-cards with higher transfer modes if supported by the carrier board.

2019-08-19ARM: dts: imx7-colibri: disable HS400Stefan Agner1-0/+1
Force HS200 by masking bit 63 of the SDHCI capability register. The i.MX ESDHC driver uses SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400. With that the stack checks bit 63 to descide whether HS400 is available. Using sdhci-caps-mask allows to mask bit 63. The stack then selects HS200 as operating mode. This prevents rare communication errors with minimal effect on performance: sdhci-esdhc-imx 30b60000.usdhc: warning! HS400 strobe DLL status REF not lock!

2017-12-26ARM: dts: imx7-colibri: add MCP2515 CAN controllerStefan Agner1-1/+12
The Colibri Evaluation Carrier Board provides a MCP2515 CAN controller connected via SPI. Note that the i.MX 7 provides an internal CAN controller which is much better suited for CAN operations. Using the MCP2515 with a Colibri iMX7 module is mainly useful to test the SPI interface.

2017-12-26ARM: dts: imx7-colibri: move and rename USB Host power regulatorStefan Agner1-1/+1
The Colibri default which enables USB Host power is not necessarily tied to the OTG2 controller, some carrier board use the pin to control USB power for both controllers. Hence name the pinctrl group more generic. Also move the regulator to the generic eval-v3 device tree since the regulator is always on the carrier board. In the Colibri iMX7S case the regulator is just not used. This allows to reuse the regulator in a upcoming SKU Colibri iMX7D 1GB with eMMC.

2017-01-29ARM: dts: imx7: Add "LPSR" to LPSR iomux pin namesSascha Hauer1-8/+8
The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr. In a board dts we have to make sure that both controllers are supplied with the correct pins. It's way too easy to do this wrong since only a look into the reference manual can reveal which pins belong to which controller. To make this clearer add "LPSR" to the pin names which belong to the LPSR controller.

Colibri modules need to be powered using the power pins 3V3 and AVDD_AUDIO. Add fixed regulators which represent this power rails. Potentially, those power rails could be switched on a carrier board. A carrier board device tree could add a own regulator with a GPIO, and reference that regulator in a vin-supply property of those new module level system regulators. This also synchronize the name of the +3.3V regulator with the one used in the Colibri VF50/VF61 device tree.
