Add UART_DMA loopback example to test M2P/P2M on eDMA. This uses UART3 (pins J1-3 Rx and J1-4 Tx on LP). Signed-off-by: Shreyas Shankar <s-shankar@ti.com>
Add m2m DMA example. Unlike the testcase dma/chan_blen_transfer, this test also uses cache APIs. Signed-off-by: Shreyas Shankar <s-shankar@ti.com>
Add example to perform spi_transceive_cb. This tests SPI Async Operation using McSPI and eDMA. This example spawns multiple threads for concurrent access of a single SPI instance. This tests SPI driver's concurrent access arbitration capability. Signed-off-by: Shreyas Shankar <s-shankar@ti.com>
Update pinctrl_msp driver to configure both iomux and pin function in case of AM13E SoC Series. Fixes: ASMZEP-94 Signed-off-by: Sameer Srivastava <s-srivastava4@ti.com>
Create header with Unicomm I2C controller FIFO trigger levels that can be set for the rxfifo-threshold and txfifo-threshold properties in devicetree. Signed-off-by: Sameer Srivastava <s-srivastava4@ti.com>
