From: Viken Dadhaniya <viken.dadhaniya@oss.qualcomm.com>

Enable GPI DMA controllers (gpi_dma0, gpi_dma1, gpi_dma2) and QUPv3
interfaces (qupv3_id_0, qupv3_id_2) in the device tree to support
DMA and peripheral communication on the Lemans EVK platform.

qupv3_id_0 provides access to I2C/SPI/UART instances 0-5.
qupv3_id_2 provides access to I2C/SPI/UART instances 14-20.

Nit: used for foo, bar, baz and slot ZYX.

Ack.

I will change it to:

qupv3_id_0 is used for I2C, SPI, UART, and slots 0 to 5.

qupv3_id_2 is used for I2C, SPI, UART, and slots 14 to 20.

No. I meant something like 'GPIO expander on I2C 2, NFC reader on I2C 10
and CAN controller on SPI 33'.
