2022-06-29ARM: dts: colibri-imx6ull: fix snvs pinmux groupMax Krummenacher
A pin controlled by the iomuxc-snvs pin controller must be specified under the dtb's iomuxc-snvs node. Move the one and only pin of that category from the iomuxc node and set the pinctrl-0 using it accordingly. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

2021-08-09cpufreq: imx6: ignore dc_regulator for toradex skusDenys Drozdov
dc_regulator is supported on NXP i.MX6UL/ULL EVK board and should be always ignored for toradex products. The regulator does not apply to the iMX6ULL 512MB, operating at 800MHz maximal clock and should be ignored for any other modules, like iMX6ULL 256MB, running at 528Mhz maximal.

Move all atmel and fusion touchscreen nodes from board-level to the main module DT. Prepare the DTs for use with atmel mxt overlays, adding required pinmux groups. The common scheme of pin groups for TS overlays: - pinctrl_atmel_conn - SODIMM 106/107 pins for INT/RST (default) - pinctrl_atmel_adap - SODIMM 28/30 pins for INT/RST signals.

2021-03-01ARM: dts: colibri-imx6ull: Change drive strength for usdhc2Philippe Schenker
The current setting reflects about 86 Ohms of source-impedance on the SDIO signals where the WiFi board is hooked up. PCB traces are routed with 50 Ohms impedance and there are no serial resistors on those traces. This commit changes the source-impedance to 52 Ohms to better match our hardware design.

All Toradex Colibri family boards support the ecspi interface. Move the definition of spidev0 to the module devicetree and enable it by default. Colibri Eval board has a CAN SPI controller. Disable the spidev0 for this board to have the CAN controller been enabled by default. Colibri Aster board supports 2 spidev interfaces. Enable both of them and fix the CS configuration.

2021-01-28ARM: dts: colibri-imx6ull: do not pull-up sd-clk but sd-cmd signalPhilippe Schenker
From the SD-Card specification: > The host shall supply power to the card so that the voltage is > reached to V DD _min within 250ms and start to supply at least > 74 SD clocks to the SD card with keeping CMD line to high. In case of > SPI mode, CS shall be held to high during 74 clock cycles. According to this information I think we should pull the CMD data line like on other boards to 3.3V. Also on other boards we do have the CLK signal pulled. This looks like this got mixed that up. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>

2021-01-27ARM: dts: colibri-imx6ull: correct wrong pinmuxing and add commentsPhilippe Schenker
Some pinmuxings are obviously wrong, originating from a copy/paste error. This patch corrects that with the following strategy: - Set all reserved bits to zero - Leave drive strength and slew rate as is - Add sensible pull and hysteresis depending on the function of the pin - Not used pins are muxed to their reset-value defined by the SoC Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> (cherry picked from commit 3eea0d71ed16ce2294fb097b1d292fc8b915f62f)

2021-01-27ARM: dts: imx6ull-colibri: fix vqmmc regulatorMax Krummenacher
The correct spelling for the property is gpios, otherwise the regulator will neither reserve nor control any gpio(s). Thus any SD/MMC card which can use UHS 1 modes will fail.

2021-01-27ARM: dts: imx6ull-colibri: reduce v_batt current in power offMax Krummenacher
Reduce the current drawn from VCC_BATT when the main power on the 3V3 pins to the module are switched off. This switches off SoC internal pull resistors which are provided on the module for TAMPER7 and TAMPER9 SoC pin and switches on a pull down instead of a pullup for the USBC_DET module pin (TAMPER2).

2019-02-11ARM: dts: imx6*-apalis/-colibri: mark I2C recovery GPIOs as open drainStefan Agner
Since commit d2d0ad2aec4a ("i2c: imx: use open drain for recovery GPIO") GPIO lib expects this GPIO to be configured as open drain. Make sure we define this GPIO as open drain in the device tree. This gets rid of the following warning: gpio-81 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file Note that currently the i.MX pinctrl driver does not support enabling open drain directly, so this patch has no effect in practice. Open drain is enabled by the fixed pinmux entry.
