2025-01-07ARM: dts: microchip: add support for sama7d65_curiosity boardRomain Sioen
Add device tree support for the SAMA7D65 Curiosity board. Update the Makefile to include the new device tree file. uart6 is related to flexcom6, hence not sorted in alphabetical order.

2025-01-02ARM: dts: microchip: sama5d27_wlsom1_ek: Add no-1-8-v property to sdmmc0 nodeCristian Birsan
Add no-1-8-v property to sdmmc0 node to keep VDDSDMMC power rail at 3.3V. This property will stop the LDO regulator from switching to 1.8V when the MMC core detects an UHS SD Card. VDDSDMMC power rail is used by all the SDMMC interface pins in GPIO mode (PA0 - PA13). On this board, PA10 is used as GPIO to enable the power switch controlling USB Vbus for the USB Host. The change is needed to fix the PA10 voltage level to 3.3V instead of 1.8V.

The AT91SAM9G25-based GARDENA smart Gateway uses USART3 (ttyS1) to communicate (over PPP, at 115200 baud) with the radio module. We have been experiencing packet loss and seeing errors on the ppp0 interface. Enabling DMA for the serial interface resolves the issues.

The UART controller does not seem to be fast enough to receive data (at 115200 baud) without dropping bytes when DMA is disabled. This has often been noticed when pasting SSH keys into the serial console (ttyS0). Only after multiple tries, the long strings would be successfully transferred without missing characters.
