* ARM: dts: Ux500: move USB PHY pins to PHY deviceLinus Walleij2017-01-311-6/+6
| | | | | | | | | | | | | | The physical pins from the SoC are in a sense belonging to the PHY device (AB8500 USB) rather than the MUSB USB IP block. The driver definately assumes so: before this change it complains that it cannot control the pins it is using: abx5x0-usb ab8500-usb.0: could not get/set default pinstate After this patch the warning goes away.

| | | | | | | | This moves the enable-active-high setting from the SoC to the board for the VMMCQ regulators. It should at least be in the vicinity of the GPIO line it is defined for. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: dts: fix the SD card on the SnowballLinus Walleij2016-10-171-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a very annoying regression on the Snowball SD card that has been around for a while. It turns out that the device tree does not configure the direction pins properly, nor sets up the pins for the voltage converter properly at boot. Unless all things are correctly set up, the feedback clock will not work, and makes the driver spew messages in the console (but it works, very slowly): root@Ux500:/ mount /dev/mmcblk0p2 /mnt/ [ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!

Add in the SDR12 and SDR25 modes which this host can do without any problems. I don't know if this has ever been correct, sadly. It works after this patch.

| | | | | | | | | | | Use the <dt-bindings/gpio/gpio.h> header instead of using hardcoded values for the GPIO flags. Eradicate the totally bogus "0x4" flag used and set that to GPIO_ACTIVE_HIGH as is proper, switch the inverted card detect on the Snowball to flag using GPIO_ACTIVE_LOW instead of using the MMC-specific inversion flag.

* ARM: ux500: Assign proper sensor IRQs for SnowballLinus Walleij2015-11-171-3/+4
| | | | | | | | | | | | | | | The Snowball gyro and magnetometer DRDY (data ready) lines are used as interrupt triggers by the IIO subsystem, triggering new data retrieveal on edges on this signal. Thus assign them as the primary interrupt in the device tree. The "other interrupt" coming out of the sensors is for alarms and similar complex events, the DRDY is for periodic measures, which is what we want. After this the generic_buffer tool from IIO tools gives a nice stream of readings after enabling the desired channels in sysfs.

* ARM: dts: fix gpio-keys wakeup-source propertySudeep Holla2015-10-221-5/+5
| | | | | | | | | | | | | | | | | | The keyboard driver for GPIO buttons(gpio-keys) checks for one of the two boolean properties to enable gpio buttons as wakeup source: 1. "wakeup-source" or 2. the legacy "gpio-key,wakeup" However juno, ste-snowball and emev2-kzm9d dts file have a undetected "wakeup" property to indictate the wakeup source. This patch fixes it by making use of "wakeup-source" property.

* ARM: ux500: fix MMC/SD card regressionLinus Walleij2015-07-141-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Ux500 is regressing due to commit a21763a0b1e5a5ab8310f581886d04beadc16616 "pinctrl: nomadik: activate strict mux mode" which disallows Nomadik GPIO 5 to be muxed in as a level shifter voltage select pin, as it is currently described as being used for RX on UART1. The behaviour is correct, instead the hardware config has been incorrecly specified: UART1 is indeed unused on HREFv60plus and Snowball and that is why HREFv60plus can use the pins it would normally occupy as the voltage select line for the MMC/SD levelshifter (Snowball uses it for I2C4). The reason UART1 was anyway enabled on these platforms was probably to secure the port enumeration to userspace. This can be solved by using aliases (done in a separate patch) so we can now deactivate UART1 and let MMC/SD use it properly on HREFv60plus. We explicitly activate it only for the older HREFprev60 board. To complete, we set up the pin configuration for these pins properly in the sdi0 node.

| | | | | | | | | | | This enumerates the PL011 serial ports on the Ux500. This is necessary to do if we want to remove one of the serial ports, since userspace depends on console to be present on ttyAMA2 and we must not break userspace.

However the HREF common dtsi and these two boards redefine the same PRCMU SoC regulators with the very same names and properties for no reason. This is like filling in the same line three times instead of drawing it once.
