2016-11-29arm: dts: imx7: specify keypad port clocktoradex_imx_4.1.15_1.0.0_ga-nextStefan Agner
To access the keypad port registers the IPG clocks need to be on, specify the clock accordingly. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
2016-11-10arm: dts: imx7: decrease DMA CMA to 128MBStefan Agner
Currently DMA CMA is set to 320MB which is rather large and cannot be allocated on Colibri iMX7S. Lower the reserved amount to 128MB which should be enouth for most use cases and works with systems which have only 256MiB memory available. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
2016-11-09ARM: 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>

2016-09-29arm: 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.

2016-09-29ARM: dts: imx7-colibri: add VBUS regulator also to OTG portStefan Agner
On some carrier boards (namely Aster, Viola and Orchid) the second USB port (USBC) is used in host only mode. In this case, the USBH_PEN signal is also used to enable USB power. This change makes sure that USBH_PEN is also set in case only one USB port is available (as it is the case on Colibri iMX7 Solo). Strictly speaking we should not add the regulator in the Evaluation Board device tree. However, we use the Evaluation Board device tree as our "Colibri Standard" device tree and it does not really hurt on the Evaluation Board...

Change the hardware reset gpio to 'GPIO6_IO15' for mipi dsi to allow fec2 and mipi dsi can run at the same time. This needs some hardware rework as follows: " 1. Replace R631 with 100K resistor; 2. Remove D14, D24; 3. Solder the Cathode of the diode to R471, you can use BAT54HT1(ONSEMI) or NSR0320MW2T1G(ONSEMI); 4. Solder the wire to the Anode end of the diode; 5.

2016-06-24ARM: dts: imx7d-colibri: Work around poweroff issueStefan Agner
The AD7879 interrupt GPIO is a wakeup pin. On poweroff, the external pull-up is not holding the GPIO high, hence causing a falling edge on the pad. Since the GPIO is a wakeup pin, this causes the SNVS Dumb PMIC to switch to on again (hence causing a reboot instead of a power- off). Make sure the interrupt line stays high during poweroff by configuring a pull-up on the IOMUXC LPSR GPR.
