This updates the i.MX8MQ device trees and, necessarily, also the i.MX8MQ clock bindings. These are taken verbatim from from the Linux kernel version v5.4-rc2, which three small changes which were already part of the previous device tree: * Keep the PSCI reserved memory range * Keep the alias for ethernet, so that the MAC address can be set * Keep the modified #include for the IOMUXC pins Signed-off-by: Patrick Wildt <patrick@blueri.se> Acked-by: Peng Fan <peng.fan@nxp.com>

2019-11-03watchdog: imx: Use immediate reset bits for expire_nowRobert Hancock
The expire_now function was previously setting the watchdog timeout to minimum and waiting for the watchdog to expire. However, this watchdog also has bits to trigger immediate reset. Use those instead, like the Linux imx2_wdt driver does. Signed-off-by: Robert Hancock <hancock@sedsystems.ca>
2019-11-03watchdog: imx: Add DT ext-reset handlingRobert Hancock
The Linux imx2_wdt driver uses a fsl,ext-reset-output boolean in the device tree to specify whether the board design should use the external reset instead of the internal reset. Use this boolean to determine which mode to use rather than using external reset unconditionally. For the legacy non-DM mode, the external reset is always used in order to maintain the previous behavior. Signed-off-by: Robert Hancock <hancock@sedsystems.ca>

2019-11-03arm: mxs: Increase VDDD voltage to match specificationMarek Vasut
According to IMX28CEC rev. 4, 10/2018, Table 15. Recommended Operating Conditions, page 16, the VDDD should be set to 1.55V when the CPU is operating at 454MHz. This is the case in U-Boot, hence increase the VDDD voltage. This fixes instability when performing TFTP transfers. Increase the brownout threshold to 1.4V. The documentation recommends 1.45V setting for the brownout, however, this triggers failure during power block init, so keep the brownout slightly lower.

2019-11-03ARM: imx: Fix bmode detection from grp10Claudius Heine
imx6_is_bmode_from_gpr9 always returns false, because IMX6_SRC_GPR10_BMODE is 1<<28 and gets casted to u8 on return. This moves the function body into imx6_src_get_boot_mode, since that is the only one using it and it is on the same abstraction level (accessing registers directly).

The requested_partitions[] array should contain only boot partitions. Usually it's only 'boot' partition, as can be seen in [1]. Also, seems like the requested_partitions[] are only used when there is no 'vbmeta' partition [2], which is not a regular use-case.
