[PATCH 01/10] ARM: dts: imx6: rdu2: enable WDOG1

[Lucas Stach]

From: Philipp Zabel <p.zabel@pengutronix.de>

Enable the i.MX6 WDOG1 internal watchdog for warm reboots. This allows
to issue emergency restarts without clearing the RAM, so collecting oops
logs from ramoops pstore in barebox becomes feasible.

[PATCH 02/10] ARM: dts: imx6: RDU2: reduce i2c drive-strength

[Lucas Stach]

The current 25 Ohm drive-strength is much too strong, resulting in
significant overshoot of the signal. Reduce the drive-strength to
75 Ohm to get rid of those issues.

[PATCH 03/10] ARM: dts: imx6: RDU2: enable RMI4 reduced reporting

[Lucas Stach]

To use the reduced reporting mode the threshold values need to be set
explicitly. Configure the threshold to be less than 0.5% of the full
touchscreen range. This seems to be a good compromise between system
load and input accurancy.

[PATCH 04/10] ARM: dts: imx6: RDU2: only trigger IRQ on falling edge ucs1002 ALERT pin

[Lucas Stach]

The ALERT signaling happens on the falling edge of the signal, as rising
edge doesn't really have any notion, as it may happen much later (due to
shared IRQ line) or too early if the chip resolves the fault itself. So
only trigger the IRQ on the edge we are actually interested in.

[PATCH 05/10] ARM: dts: imx6: RDU2: adjust audio devices nomenclature

[Lucas Stach]

From: Cory Tusar <cory.tusar@zii.aero>

This adds a "HPA1" prefix to the amplifiers on both audio cards, this is
done in order to get more consistency for userspace running on RDU2 and
RDU3, where we have two amplifiers on a single card device in the "Zest"
configuration.

Also adjust the card names to the new standard expected by userspace.

[Lucas Stach]

Reduce slew rate and set drive strength to 105 Ohm. The previous settings
had some issues with signal ringing, due to the slew rate being too fast.

[PATCH 08/10] arm64: dts: zii-ultra: limit USB ports to USB2 speed

[Lucas Stach]

The internal USB is connected to a USB2 hub, the front-panel USB
is wired directly, but does not support USB3 speeds electrically.
Limit both ports accordingly.

[PATCH 09/10] arm64: dts: zii-ultra: only trigger IRQ on falling edge ucs1002 ALERT pin

[Lucas Stach]

The ALERT signaling happens on the falling edge of the signal, as rising
edge doesn't really have any notion, as it may happen much later (due to
shared IRQ line) or too early if the chip resolves the fault itself. So
only trigger the IRQ on the edge we are actually interested in.

[PATCH 10/10] arm64: dts: zii-rmb3: enable RMI4 reduced reporting

[Lucas Stach]

To use the reduced reporting mode the threshold values need to be set
explicitly. Configure the threshold to be less than 0.5% of the full
touchscreen range. This seems to be a good compromise between system
load and input accurancy.
