arm: mvebu: add Synology DS213j and DS414 .dts files

Hi,

This series adds .dts files for Synology DS213j (armada 370 2-bay NAS) and DS414 (armada XP 4-bay NAS) devices. It is based on comments received on a v0 submission of DS213j .dts file [1] and Andrew's comments on a v1 ( for both DS213j and DS414 .dts files) [2] and Andrew/Sebastian' comments on v2 regarding pinctrl improvements [3].

Cheers,

a+

[3]: http://thread.gmane.org/gmane.linux.drivers.devicetree/98892

Changes since v2:

- Added various patches to improve/refactor Armada 370/XP pinctrl nodes/properties and use sensible defaults when possible.
- changed gpio-fan,speed-map to better match max rotation speed (1900 RPM) for DS213j

Changes since v1:

- Added a patch to fix Seiko Instruments, Inc. prefix from "ssi" to "sii" for s35390 RTC chip in kirkwood-synology.dtsi as reported by Andrew
- Fixed DS414 and DS213j .dts files which had the same issue due to a blind copy-and-paste.
- Added a patch for armada-xp-lenovo-ix4-300d.dts to use uart alias for stdout-path, as suggested by Andrew.
- removed pinctrl properties for ethernet interface wrongly referencing a RGMII pin configuration: the PHY is connected using SGMII.
- moved some DS213j pinctrl entries (spi0, uart0) in armada-370.dtsi
- same thing for DS414 pinctrl entries (ge0/1, spi0) moved to armada-xp-mv78230.dtsi
- changed pinctrl nodes and labels to match naming convention found in .dtsi: pmx_*: pmx- changed to *_pin: -pin.
- same thing for DS414
- added a comment in the .dts file about DS414 being susceptible at boot when an USB/serial converter is connected to the UART pins.

Changes since v0:

- Added a comment at the beginning of DS213j and DS414j .dts file regarding the need for a recent Marvell bootloader. Arnd suggested to do a specific .dtb file for new and old bootloaders but I think if we follow this path for DS414 and DS213j, we will probably have to do it for all Armada-based synology NAS and possibly for other Armada 370/XP based devices. Opting for recent bootloaders config and having a comment is easier. It is likely that a user already has a recent bootloader. Otherwise, upgrade is a one click process anyway. If a user thinks it is easier to have two different .dts files in the kernel, she will still be able to push a patch.
- Added a comment in the .dts file about the bootloader screwing the kernel if the environment is saved.
- Kept GPL licence for .dts file
- Fixed bad naming of node and alias (_ vs -)
- Added micron vendor prefix for n25q064 flash
- Disabled SoC RTC; a Seiko S-35390A is used as main RTC
- Added comments about the purpose of each serial port
- Added stdout-path = &uart0; to help barebox. A specific patch is included in the series to provide labels for uart serial nodes
- Added patch for DS414 .dts file

2.1.1

Micron vendor prefix is not listed yet in vendor-prefixes.txt file. Even if the expected vendor prefix should be the NASDAQ symbol ("mu" in that case), it seems reasonable to use "micron" here because it is what is already found at various locations (e.g. under arch/arm/boot/dts/ for instance).

2.1.1

As reported by Andrew, the vendor prefix for Seiko Instruments, Inc. S-35390A I2C RTC chip in kirkwood-synology.dtsi has a typo (ssi instead of sii). This patches fixes it.

2.1.1

This patch adds uartX labels for Armada SoC serial nodes. This is a preliminary work to be able to easily reference the serial lines in Device Tree files. One expected use is when providing stdout-path property for barebox.

Now that labels for uartX are available in Marvell Armada .dtsi files, this patch replaces the "/soc/internal-regs/serial at 12000" found in armada-xp-lenovo-ix4-300d.dts file for stdout-path property by the more concise &uart0.

2.1.1

As suggested by Sebastian and Andrew, it is possible to refactor and remove duplications in pinctrl nodes for Armada 370/XP in the following way:

1) define a pinctrl node in armada-370-xp.dtsi w/ only the reg property defined (same for all 370/XP SoCs)
2) remove now redundant reg properties in armada-370.dtsi and armada-xp-mv*.dtsi files
3) move identical and redundant SDIO pins definitions found in armada-xp-mv*.dtsi to a newly created pinctrl node in armada-xp.dtsi

2.1.1

This patch defines common Armada 370 pinctrl settings for spi0 and spi1 interfaces:

spi0: MPP33-36 as default, MPP32,63-65 as available alternate config
spi1: MPP49-52 as default

Currently, the Armada 370 DB .dts file has no explicit pinctrl info for the spi0 interface used to access the flash on the board. The patch fixes that by also adding explicit pinctrl info (MPP32,63-65) for this SPI interface.

Note: this patch has the potential to break out-of-tree users w/o specific pinctrl settings for their spi interfaces if the default above does not match their config.

Armada XP AXWiFiAP has local definitions for ge0/1 rgmii pinctrl settings which can be be used by other boards. This patch moves those definitions to armada-xp.dtsi file and then reference those pinctrl entries in all current .dts files using ge0/1 interface in rgmii-id mode for their PHY.

2.1.1

This patch defines common Armada XP pinctrl settings in armada-xp.dtsi for the supported SPI interface (MPP36-39) and use it as default for Armada XP spi interface.

Note: this patch has the potential to break out-of-tree users w/o specific pinctrl settings for their spi interfaces if the default above does not match their config (i.e. if they do not use CS0).

2.1.1

Synology DS213j is a 2-bay NAS powered by a Marvell Armada 370 (88F6710 @1.2Ghz). It is very similar on many aspects to previous 2-bay synology models based on Marvell kirkwood SoC. Here is a short summary of the device:

- 512MB RAM
- boot on SPI flash (64Mbit Micron N25Q064)
- 1 GbE interface (Armada MAC connected to a Marvell 88E1512 PHY via SGMII)
- 2 rear USB 2.0 ports (directly handled by the Armada 370)
- 2 internal SATA ports handled by the Armada 370: 2 GPIO for presence, 2 for powering them
- two front amber LED (disk1, disk2) controlled by the SoC
- Seiko S-35390A I2C RTC chip
- UART0 providing serial console
- UART1 used for poweroff (connected to a TI MSP430F2111)
- Fan handled via 4 GPIO (3 for speed, 1 for alarm)

Synology DS414 is a 4-bay NAS powered by a Marvell Armada XP (mv78230 dual-core @1.33Ghz). It is very similar on many aspects to previous 4-bay synology models based on Marvell kirkwood SoC. Here is a short summary of the device:

- 1GB RAM
- Boot on SPI flash (64Mbit Micron N25Q064)
- 2 GbE interfaces (Armada MAC connected to two Marvell 88E1512 PHY via RGMII)
- 1 front USB 2.0 ports (directly handled by the Armada 370)
- 2 rear USB 3.0 ports (handled by an EtronTech EJ168A XHCI controller on the PCIe bus)
- 4 internal SATA ports handled by a Marvell 88SX7042 SATA-II controller on the PCIe bus)
- Seiko S-35390A I2C RTC chip
- UART0 providing serial console
- UART1 used for poweroff (connected to a Microchip PIC16F883)

Additional note: the front LEDs the and the two fans are not directly connected to the SoC and under its control. The former are presumably driven by the SATA controller, the latter by the PIC.

2.1.1

Arnaud,

sorry I didn't remember earlier, but there has been a similar patch set that already deals with Armada-XP pinctrl and ethernet settings [1].

[1]
https://lkml.kernel.org/g/1411157684-6991-1-git-send-email-sebastian.hesselbarth at gmail.com

It has already been merged by Jason into mvebu/dt for v3.19, so it seems you'll have to rebase your patches on top of it. AFAIKS, you can drop pinctrl node consolidation for the SoCs (XP at least) and RGMII consolidation. The other changes you did for common 370/XP dtsi, UART, and SPI are valuable and you should keep them.

If I find some time, I'll have a closer look at both patch sets. Sorry again for not remembering earlier!

Sebastian

Already have the same patch queued up.

Rob

Hi Sebastian,

I'll rebase the whole series and send a v4.

no problem.

Cheers,

Hi,

Perfect, I'll drop mine.

Cheers,
