ARM: dts: Disable DMA support on the BK4 vf610 device's fsl_lpuart
This change disables the DMA support (RX/TX) on the NXP's fsl_lpuart driver - the PIO mode is used instead. This change is necessary for better robustness of BK4's device use cases with many potentially interrupted short serial transfers. Without it the driver hangs when some distortion happens on UART lines.

ARM: dts: vf610-bk4: Fix qspi node description
Before this change the device tree description of qspi node for
second memory on BK4 board was wrong (applicable to old, removed
fsl-quadspi.c driver).
As a result this memory was not recognized correctly when used
with the new spi-fsl-qspi.c driver.
From the dt-bindings:
"Required SPI slave node properties:
- reg: There are two buses (A and B) with two chip selects each.
This encodes to which bus and CS the flash is connected:
<0>: Bus A, CS 0
<1>: Bus A, CS 1
<2>: Bus B, CS 0
<3>: Bus B, CS 1"
According to above with new driver the second SPI-NOR memory shall
have reg=<2> as it is connected to Bus B, CS 0.
Fixes:

ARM: SoC device tree updates for 5.1
This is a smaller update than the past few times, but with just over
500 non-merge changesets still dwarfes the rest of the SoC tree.
Three new SoC platforms get added, each one a follow-up to an existing
product, and added here in combination with a reference platform:
- Renesas RZ/A2M (R7S9210) 32-bit Cortex-A9 Real-time imaging processor
https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rza/rza2m.html
- Renesas RZ/G2E (r8a774c0) 64-bit Cortex-A53 SoC "for
Rich Graphics Applications".
https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rzg/rzg2e.html
- NXP i.MX8QuadXPlus 64-bit Cortex-A35 SoC
https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-8-processors/i.mx-8x-family-arm-cortex-a35-3d-graphics-4k-video-dsp-error-correcting-code-on-ddr:i.MX8X
These are actual commercial products we now support with an in-kernel
device tree source file:
- Bosch Guardian is a product made by Bosch Power
Tools GmbH, based on the Texas Instruments AM335x chip
- Winterland IceBoard is a Texas Instruments AM3874 based
machine used in telescopes at the south pole and elsewhere, see commit

ARM: dts: vf610-bk4: fix incorrect #address-cells for dspi3
The dspi3 is used as slave controller on vf610-bk4, and the default '#address-cells = <1>;' setting in vfxxx.dtsi causes the following DTC warning. DTC arch/arm/boot/dts/vf610-bk4.dtb ../arch/arm/boot/dts/vfxxx.dtsi:550.24-563.6: Warning (spi_bus_bridge): /soc/aips-bus@40080000/spi@400ad000: incorrect #address-cells for SPI bus also defined at ../arch/arm/boot/dts/vf610-bk4.dts:107.8-119.3 arch/arm/boot/dts/vf610-bk4.dtb: Warning (spi_bus_reg): Failed prerequisite 'spi_bus_bridge' For spi device used as slave controller, '#address-cells' should be 0. Let's overwrite the property in vf610-bk4.dts to fix the warning. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Shawn Guo <shawnguo@kernel.org> |

ARM: dts: vf: Fix memory node duplication
Boards based on vf500/vf600 have duplicate memory nodes: - One coming from the board dts file: memory@ - One coming from the vf500.dtsi/vf610m4.dtsi files. Fix the duplication by removing the memory node from the dtsi file and by adding 'device_type = "memory";' in the board dts.
