phyCORE-AM335x is a SoM (System on Module) containing a AM335x SOC. The module can be connected to different carrier boards.
Some hardware parts are configurable on the phyCORE-AM335x. So they are disabled on default in this som dtsi file. They will be enabled in the board dts files, when populated. * RAM up to 1GiB * PMIC * NAND flash up to 1GiB * Eth PHY on SOM: 1x RMII * SPI NOR flash 8MiB (optional) * i2c RTC (optional) * i2c EEPROM 4kiB (optional) Signed-off-by: Teresa Remmet <t.rem...@phytec.de> --- arch/arm/boot/dts/am335x-phycore-som.dtsi | 368 ++++++++++++++++++++++++++++++ 1 file changed, 368 insertions(+) create mode 100644 arch/arm/boot/dts/am335x-phycore-som.dtsi diff --git a/arch/arm/boot/dts/am335x-phycore-som.dtsi b/arch/arm/boot/dts/am335x-phycore-som.dtsi new file mode 100644 index 0000000..4d28fc3 --- /dev/null +++ b/arch/arm/boot/dts/am335x-phycore-som.dtsi @@ -0,0 +1,368 @@ +/* + * Copyright (C) 2015 Phytec Messtechnik GmbH + * Author: Teresa Remmet <t.rem...@phytec.de> + * + * This program is free software;
