Poslab Savageboard is i.MX6 SoC base, but BSP code from the vendor is
not mainline u-boot and kernel. Personal reason of using this board is
testing etnaviv user-space driver, so I re-write device tree files based on
mainline kernel for the first step.
This patchset includes common DT file, dual and quad board files.
Supported components are
- Display: HDMI and LVDS panel
- eMMC and SD card
- Ethernet
- Pinmux configuration
- SATA: only for Savageboard quad
- UART1 for debug console
- USB host
Missing features are
- Audio (WM8903)
- USB OTG
- PMIC WM8326: default settings are used so no issue to bring-up the system
- MIPI DSI, CSI
Patches are tested on the Savageboard quad but the dual version should work
because the only difference between dual and quad is SATA support.
More information in http://www.savageboard.org
v2:
Fix DT node for regulator, phy-reset-gpios and iomuxc node.

2.9.3
* Memory
memblock for DDR3 1GB
* Regulator
3.3V for panel and backlight.
* Display
Enable HDMI and LVDS panel. Savageboard supports AVIC TM097TDH02 panel
which is compatible with Hannstar HSD100PXN1, so reuse it.
* Clock
The commit d28be499c45e6 is applied to support LVDS and HDMI output
simultaneously.
* Pinmux
eMMC, ethernet, HDMI, I2C, power button, PWM, SD card and UART.
* Others
Enable ethernet, UART1 debug, USB host, USDHC3 for microSD card and
USDHC4 for built-in eMMC storage.

Oh, I didn't notice because I build the dtbs manually.
Thanks for catching this.
And do you think other patches look OK?
