2017-06-17ARM: dts: imx7-colibri: assign LDO2 to USDHC2 by defaultStefan Agner
The USDHC instance 1 is powered with a separate rail. This allows to switch voltage of the SD card signals for higher speed modes such as UHS-I. The reset state of that rail is enabled and 3.3V. Revision before Colibri iMX7S V1.1C and iMX7D V1.1D had that rail connected to +3.3V rail switchable with a PMIC GPIO which turned out to be not controllable in regular run mode and to LDO2. Colibri iMX7S V1.1C and iMX7D V1.1D and later connect it to the PMIC LDO2 only, which allows to control the voltage directly. This change explicitly assigning the PMIC regulator which allows the SDHC driver code to control the SD card voltage and hence negotiate higher speeds for SD cards capable of UHS-I or later. Note that the carrier board device tree needs to be adjusted too (see comments at the usdhc1 node) and the carrier board should have no pull-ups populated.

2017-06-17ARM: dts: imx7-colibri: Add new hoggrp for GPIO4_IO23Sanchayan Maity
Add a new hoggrp just for GPIO4_IO23 pin at the module level. Add this new group to pinctrl-0 in iomuxc by default at module level and overwrite it at Aster carrier board level without the new hoggrp-6. This is required so this pin is muxed as GPIO at module level but can be used by SPI driver as chip select for Aster carrier board on RPi header X20.

2017-04-03ARM: dts: imx7-colibri: use pull-down for USBC_DET pinStefan Agner
The Standard Colibri pin for Client/Host detection USBC_DET (SODIMM pin 137) is multiplexed on the module with USB_OTG1_VBUS. The USB_OTG1_VBUS pad seems to be pulled low by default and not controllable through pinctrl. When the pin is unconnected on the Carrier board, the pin is at a intermediate voltage level which is not ideal. Pull-down the pin to make sure that the pin is at a defined state by default (low, USB host).

2017-04-03ARM: dts: imx7-colibri: use round numbersStefan Agner
Use round voltages as it is common in other device trees. Also fix wrong voltage of PWR_EN_+V3.3 rail. The error had no noticeable effect since no customer explicitly requested a specific voltage.

2017-04-03ARM: dts: imx7-colibri: allow to disable Ethernet railStefan Agner
The regulator-always-on property on the Ethernet rail prevents Linux from disabling the rail when Ethernet is shut down (suspend or simply link down). With this change the regulator framework will disable the rail when the Ethernet PHY is not used, saving power especially on carrier board not using Ethernet.

2017-01-10ARM: dts: imx7-colibri: Fix use of pull-up by SODIMM 45Sanchayan Maity
The iMX7 wakeup pin currently has a 47k pullup configured. Thus one has to pull the pin to 0V to generate the wakeup event. All other Colibri modules use pull downs and require 3.3V to generate an event. Also on the Colibri Evaluation Board an external 100kOhm pulldown is connected, thus the pin is neither at 0V nor 3.3V but at 2.2V potentially increasing power consumption. Change logic to use pulldown and require 3.3V to generate wakeup event. Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com> Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
2017-01-10arm: dts: imx7: mux pad of SODIMM 169 as GPIOStefan Agner
The pad SAI1_RX_DATA can be used as second chip select for dual-die NAND. However, with an assembly option the pad is available as GPIO on SODIMM 169. All current version of Colibri iMX7 modules have the pad available as GPIO hence mux it as GPIO by default.
