The Toradex Colibri family is composed of a SoM that can be plugged on various carrier boards, with carrier boards allowing multiple optional accessories (e.g. display, camera, ...). The device tree sources are structured into a SoM dtsi and a carrier dts which then includes the SoM dtsi. The SoM dtsi defines and enables the functionality self-contained on the SoM and prepares for the functionality provided by the carrier HW or accessories so that the carrier dts then can enable or amend nodes provided. Accessories are enabled in overlays depending on HW configuration. Please find the following colibri-imx6ull device trees improvements: - MMC/SD The original Colibri specification only defined 3.3 volt TTL signaling and relied on external on-carrier pull-ups for the SD_DATA[0..3] lines. The latest carrier boards like Iris V2 on the other hand are now UHS-I compliant by leaving such external on-carrier pull-ups away relying on module- or even SoC-level ones which pull up to resp. signaling voltage. In such cases, the carrier board-level device tree may explicitly delete the no-1-8-v property to enable full UHS-I support. Also, fix SD/MMC regulator for the carrier boards using UHS-I modes. - FEC Provide a proper phy-supply for the FEC, actually switched by the 50 Mhz RMII interface clock using a regulator-fixed-clock that is now properly stated. The reference commit for such regulator can be found at commit 8959e5324485 ("regulator: fixed: add possibility to enable by clock"). - I2C Switched on 22 kOhm pull-ups and lower the I2C frequency to 40 kHz to get more reliable communication. - Atmel Touchscreen The Toradex 7" Capacitive and 10" LVDS touch screens are Atmel MXT peripherals available on the I2C bus for touchscreen events. Add atmel_mxt_ts node to the module-level device tree. Also, provide pinmux configuration for the INT/RST inputs from SODIMM pins 106/107 for most carrier boards or an external touchscreen adapter inputs configured to SODIMM pins 28/30. Changes in v3: - Fixed reset GPIO polarity in-line with the following upstream commit: feedaacdadfc ("Input: atmel_mxt_ts - fix up inverted RESET handler") - Fixed comment using more common SODIMM followed by number naming. - Replaced underscores by dashes in GPIO hog node names. - Added more LVDS specific GPIO hogs in-line with other modules. - Re-based on top of Shawn's imx/dt branch. - Dropped [PATCH v2 08/14] dt-bindings: arm: fsl: add toradex,colibri-imx6ull which already got applied by Shawn. Thanks! Changes in v2: - Fixed pinctrl node names as suggested by Shawn. - Fix alphabetical node order as suggested by Shawn. - Dropped [PATCH v1 02/14] ARM: dts: imx6ull-colibri: fix vqmmc regulator which already got applied by Shawn.
