[v6] arm64: dts: qcom: lemans-evk: Extend board support for additional peripherals

[PATCH v6 02/10] arm64: dts: qcom: lemans-evk: Enable GPI DMA and QUPv3 controllers

Posted by Wasim Nazir 2 weeks, 1 day ago

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 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.

Don't rush sending the next iteration until the discussions have been
sorted out.
