99ae78f1fc ARM: dts: iwg22d-sodimm: Enable touchscreen
In one of the iWave-G22D development board variants, called Generic SODIMM
Development Platform, we have an LCD with touchscreen. The resistive touch
controller, STMPE811 is on the development board and is connected through
the i2c5 of the RZ-G1E.

Additionally, this controller should generate an interrupt to the CPU and
it is connected through GPIO4,4 to the GIC.

Touch was tested with one of our iW-RainboW-G22D-SODIMM RZ/G1E development
platforms.

GPIO pull-up configuration for power enable, R[2:7], G[2:7], B[2:7],
VSYNC, HSYNC, DU0_DISP and, DU0_CLK as inputs.

There is no encoder between the DU and the panel, therefore the default
connector driver is used.

The two variants of the iW-G22D should be mutually exclusive, therefore
this patch also disables the RGB LCD display when the HDMI extension board
is used.

axis) and rotate 180 degrees around the y axis because the device sits on

b1520d8b9b arm64: dts: ls1028a: add node for Felix switch
Add the switch device node, available on PF5, so that the switch port
sub-nodes (net devices) can be linked to corresponding board specific
phy nodes (external ports) or have their link mode defined (internal
ports).

The switch device features 6 ports, 4 with external links and 2
internally facing to the LS1028A SoC and connected via fixed links to 2
internal ENETC Ethernet controller ports.

Add the corresponding ENETC host port device nodes, mapped to PF2 and
PF6 PCIe functions. Since the switch only supports tagging on one CPU
port, only one port pair (swp4, eno2) is enabled by default and the
other, lower speed, port pair is disabled to prevent the PCI core from
probing them. If enabled, swp5 will be a fixed-link slave port.

DSA tagging can also be moved from the swp4-eno2 2.5G port pair to the
1G swp5-eno3 pair by changing the ethernet = <&enetc_port2> phandle to
<&enetc_port3> and moving it under port5, but in that case enetc_port2
should not be disabled, because it is the hardware owner of the Felix
PCS and disabling its memory would result in access faults in the Felix
DSA driver.

All ports are disabled by default, including the CPU port, and need to
be enabled on a per-board basis.

The phy-mode binding of the internal ENETC ports was modified from
"gmii" to "internal" to match the phy-mode of the internal-facing switch
ports connected to them. The ENETC driver does not perform any phy_mode
validation anyway, so the change is only cosmetic. Also, enetc_port2 is
defined as a fixed-link 1000 Mbps port even though it is 2500 Mbps (as
can be seen by the fact that it is connected to mscc_felix_port4). The
fact that it is currently defined as 1000 Mbps is an artifact of its
PHYLIB implementation instead of PHYLINK (the former can't describe a
fixed-link speed higher than what swphy can emulate from the Clause 22
MDIO spec).

The switch's INTB interrupt line signals:
- PTP TX timestamp availability
- TSN Frame Preemption

And don't forget to enable the 4MB BAR4 in the root complex ECAM space,
where the switch registers are mapped.

50f5b89a32 ARM: dts: imx6: phycore-som: add da9062 gpio support
The pmic is a mfd device and supports gpios. Those gpios are not routed
to the SoM baseboard pin header but they are connected to the i.MX6. We
need the GPIO's to configure the pmic to select between the
suspend/resume arm and soc voltages

1f4e29d24b ARM: dts: imx6: phycore-som: explicit disable pmic watchdog during suspend
By default the phycore-som has support for two watchdog devices: 1st the
internal imx6 watchdog and 2nd the DA9062 PMIC watchdog. According [1]
the PMIC watchdog is used as boot watchdog. It is common to use this
watchdog during "system up" time too. Furthermore the PMIC watchdog can
be used to address ERR007117 since the phycore-som can be equipped with
NAND or eMMC storage.

The PMIC watchdog can be enabled/disabled by the PMIC itself if the PMIC
enters POWERDOWN mode or by the host. The PMIC powerdown mode can't be
used due to the PCB design. So the watchdog is still enabled during a
suspend which causes a system reset. We need to tell the driver to
disable the watchdog during a system suspend and to reenable it upon a
resume to fix this.

135be16d35 ARM: dts: imx7s: add snvs clock to pwrkey
On i.MX7, the SNVS requires a clock. This is similar to the clock
bound to the SNVS RTC node, but if the SNVS RTC driver isn't enabled,
then SNVS doesn't work, and as such the pwrkey driver doesn't
work (i.e. hangs the kernel, as the clock isn't enabled).

Also see commit ec2a844ef7
("ARM: dts: imx7s: add snvs rtc clock")
for a similar fix.
