Various pins for UART0 and UART1, whether you use CTS/RTS or not, etc. I believe this is really the sort of pin mux configuration that is best left at the board level. Best regards, Thomas

Hi Thomas Lets look at this from the perspective of lies, damn lies, and statistics: Kirkwood has a default pinmux configuration in kirkwood.dtsi. Two of the sixty six .dts files overwrite the defaults. Dove has a default pinmux of uart1, but none for uart0. None of the .dts files define a pinmux for uart0 and none overwrite the defaults for uart1. Armanda XP has a default pinmux for uart2 and uart2 in armada-xp.dtsi, but none for uart0 or uart1. None of the .dts files define a pinmux for uart0 or uart1, and none overwrite the defaults for uart2 or uart3. Armada 370 has default pinmux for uart0 and uart1. None of the .dts files overwrite the defaults. I'm too lazy to look at 375, 380, and 385. We have over 80 dts files here with defaults from a .dtsi file, and only two need anything other than defaults.

Fair enough :) Thomas

This commit adds the Device Tree files for the Armada 39x family of processors, as well as one Armada 398 Development Board. Like for other Marvell EBU families, a common armada-39x.dtsi contains the description of the common features of all Armada 39x SoCs, while armada-390.dtsi and armada-398.dtsi respectively describe the specificities of those SoCs. Finally, an armada-398-db.dts file is added to describe the Armada 398 Development Board itself. So far, the following features are supported: * SMP: dual Cortex-A9 * Basic ARM IPs: SCU, timer, GIC * Basic Marvell IPs: pin-muxing, clocks, system controller, MBus controller, MPIC interrupt controller, timer, CPU reset for SMP, PMSU. * I2C * UART * PCIe Additional features will be supported in the future.
