I have fixed the mappings for DNS-327L in this patch Changelog since last respin: * All the style fixes * pinctrl fixes for uart1 Fixed and updated description of the patch from my first email follows. DNS-327L is a 2-bay NAS with the following specs: - 512MiB RAM - 128MiB NAND Flash - 1 GbE interface (Marvell PHY) - 1 rear USB 3.0 port (via PCIe USB 3.0 controller) - 2 internal SATA ports handled by the Armada 370: uses 2 gpios for power control - two front 2-color leds (amber + white) for both discs, controlled by the SoC - One white LED handled by SoC (USB) - 3 buttons. Power handled by weltrend, USB and RESET (on the bottom) are wired via GPIOs - Unidentified i2c device at address 0x13 (via i2cdetect) - UART0 providing serial console - Weltrend MCU serving for RTC, temperature, fan control, and power button handling interfaced via UART1 (Handled via userspace dns320l-daemon) Hardware notes follow: Everything's supported, save for mysterious i2c device at address 0x13 (any ideas what can it be?) that I couldn't even find on the PCB. Stock firmware performs some messing with PHY registers (that have no public documentation) using a userspace script. Using upstream kernel it is possible to match the stock behavior using the following in u-boot prompt: /* Set RGMII voltage to 1.8v, according to public docs. Nice! */ mw.l 0xd00184e0 0xa8a; /* Some weird magic that goes into phy registers, no public docs */ phyWrite 0 16 2; phyWrite 0 19 77; phyWrite 0 18 5747; Andrew Andrianov (1): ARM: mvebu: dts: Add dts file for DLink DNS-327L arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/armada-370-dlink-dns327l.dts | 349 ++++++++++++++++++++++++ 2 files changed, 350 insertions(+) create mode 100644 arch/arm/boot/dts/armada-370-dlink-dns327l.dts -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
