DRA821U: McSPI's MOSI and MISO pin swapped

Tool/software:

Hi there,

I configure main domain SPI 1's pin M19 (MMC1_DATA0.SPI1_D0) as output and pin M20 (MMC1_CMD.SPI1_D1) as input (see line# 5 and 6 in the dts configuration below). However, when we type SPI test command 

 spidev_test -v -D/dev/spidev1.0 -p x\55aa55aa

we saw from oscilloscope screen (screenshot is attached at the bottom) that SPI1_D1 became output (i.e., MOSI) and SPI1_D0 became input (i.e., MISO). Did I miss some configuration in device tree below?

Thanks,

Charles
