DWC3 device found on Exynos SoCs cannot work in OTG mode alone, because
it lacks some OTG related control part. OTG mode operation is possible
only with external hardware logic (usually GPIO-based) specific to
the board. Right now, however, there is no driver for such logic and no
bindings, so the OTG mode is dysfunctional at all (this means that it
doesn't work as a peripheral nor as a host). This patch sets the operation
mode to peripheral to get DWC3_1 device at least somehow working. This can
be later updated, when proper OTG driver and bindings get developed.

Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.
Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */

There's a 2GB emmc on hp t410 that's wired to the sd_2 interface.
Note that we also need to configure the evtmux using edma_xbar for
edma channels.
Let's use the McASP2 channels like the original kernel seems to be
doing, most likely the audio on t410 is different from dm814x-evm.

Enabling CPUFreq support for Tegra124 Chromebooks is causing the Tegra124
to hang when resuming from suspend.
When CPUFreq is enabled, the CPU clock is changed from the PLLX clock to
the DFLL clock during kernel boot. When resuming from suspend the CPU
clock is temporarily changed back to the PLLX clock before switching back
to the DFLL. If the DFLL is operating at a much lower frequency than the
PLLX when we enter suspend, and so the CPU voltage rail is at a voltage
too low for the CPUs to operate at the PLLX frequency, then the device
will hang.
Please note that the PLLX is used in the resume sequence to switch the CPU
clock from the very slow 32K clock to a faster clock during early resume
to speed up the resume sequence before the DFLL is resumed.
Ideally, we should fix this by setting the suspend frequency so that it
matches the PLLX frequency, however, that would be a bigger change. For
now simply disable CPUFreq support for Tegra124 Chromebooks to avoid the
hang when resuming from suspend.

Previously, the device tree mapped the FPGA like any other IPs inside
the SoC, but it is actually mapped through the WEIM (Wireless External
Interface Module). This patch updates the device tree to make use of it.
About the timings: in the image provided by the manufacturer, only
CS0GCR1 is changed. The other values are the default ones, but the WEIM
bindings expect them to be all explicitly set in the device tree, so I
just put the default values in the dt.

Add Colibri standard pinmux for FlexCAN controller instances. CAN
is not a standard Colibri feature, but the datasheet predefines
pins which provide CAN (compatible across some modules). Hence,
add the pinmux on module level.

This has been moved to the reg property where it belongs for quite some
time. The range has been unused by the kernel since then and with kernel
4.4 it's flagged as an unparsable range, as it does not comply to the
PCI ranges DT binding. Fix this by removing the superfluous range.

Audio IP need the spba clock, but original clock name "dma" is not
accurate, so change it to name "spba". The audio driver has been
using the new name "spba", the binding document has been updated.

Ventana boards have an off-board connector with signals that can be pinmuxed
as either GPIO or PWM. This patch adds pwm device-tree nodes in the disabled
state which the bootloader can decide to enable based on bootloader config.

imx6qdl.dtsi uses compatibles "fsl,imx6q-gpt", "fsl,imx31-gpt".
imx6dl.dtsi uses compatibles "fsl,imx6dl-gpt", "fsl,imx6q-gpt" since
commit
4e415ed814 (ARM: dts: imx6dl: add imx6dl gpt specific compatible string)
If imx6dl would be compatible with imx6q-gpt it would also have to be
compatible with imx31-gpt which is currently missing.
Based on the above mentioned patch I assume imx6q-gpt and imx6dl-gpt are
not compatible. So imx6q-gpt should be removed as compatible.

Currently it is not possible to have HDMI and LVDS working simultaneously,
because both ports try to use PLL5.
Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
driven from independent sources.
With this change the LDB pixel clock goes to 68.57 MHz, which is still
within the valid range for the displays supported by the Ventana boards.
