* ARM: dts: Disable DMA support on the BK4 vf610 device's fsl_lpuartLukasz Majewski2019-10-251-0/+4
| | | | | | | | | | | | | 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 descriptionLukasz Majewski2019-08-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
