92b7cb5dc8 extcon: palmas: Support GPIO based USB ID detection
Some palmas based chip variants do not have OTG based ID logic.
For these variants we rely on GPIO based USB ID detection.

These chips do have VBUS comparator for VBUS detection so we
continue to use the old way of detecting VBUS.

bf64dd262e ARM: ux500: add an SMP enablement type and move cpu nodes
The "cpus" node cannot be inside the "soc" node, while this
works for the CoreSight blocks, the early boot code will look
for "cpus" directly under the root node, so this is a hard
convention. So move the CPU nodes.

Augment the "reg" property to match what is actually in the
hardware: 0x300 and 0x301 respectively.

Then add an SMP enablement type to be used by the SMP init
code, "ste,dbx500-smp".

7b9c5162c1 serial: etraxfs-uart: use mctrl_gpio helpers for handling modem signals
In order to use the mctrl_gpio helpers, we change the DT bindings:
ri-gpios renamed to rng-gpios. cd-gpios renamed to dcd-gpios.
However, no in-tree dts/dtsi specifies these, so no worries.

62f4666968 Input: zforce - make the interrupt GPIO optional
Add support for hardware which uses an I2C Serializer / Deserializer
(SerDes) to communicate with the zFroce touch driver. In this case the
SerDes will be configured as an interrupt controller and the zForce driver
will have no access to poll the GPIO line.

To support this, we add two dedicated new GPIOs in the device tree:
reset-gpios and irq-gpios, with the irq-gpios being optional.

To not break the existing device trees, the index based 'gpios' entries
are still supported, but marked as deprecated.

With this, if the interrupt GPIO is available, either via the old or new
device tree style, the while loop will read and handle the packets as long
as the GPIO indicates that the interrupt is asserted (existing, unchanged
driver behavior).

If the interrupt GPIO isn't available, i.e. not configured via the new
device tree style, we are falling back to one read per ISR invocation
(new behavior to support the SerDes).

Note that the gpiod functions help to handle the optional GPIO:
devm_gpiod_get_index_optional() will return NULL in case the interrupt
GPIO isn't available. And gpiod_get_value_cansleep() does cover this, too,
by returning 0 in this case.

c934b36127 phy: ti-pipe3: i783 workaround for SATA lockup after dpll unlock/relock
SATA_PLL_SOFT_RESET bit of CTRL_CORE_SMA_SW_0 must be toggled
between a SATA DPLL unlock and re-lock to prevent SATA lockup.

Introduce a new DT parameter 'syscon-pllreset' to provide the syscon
regmap access to this register which sits in the control module.

If the register is not provided we fallback to the old behaviour
i.e. SATA DPLL refclk will not be disabled and we prevent SoC low
power states.
