Cover letter [PATCH 0/3] ARM: dts: sun8i-a33: Support for Sinlinx SinA33 dev board
Hi,

Hi Maxime,
This series enables support for the Sinlinx SinA33 dev board. This is a core/daughter board SDK kit from Chinese vendor Sinlinx. The core board itself does not have any special connectivity, so I didn't split them into 2 files.
The series is based on Vishnu/Hans' A33 series (v2). As the last (dts) patch was not merged yet, there might be a conflict in dts/Makefile.
Patch 1 adds a pinmux setting for uart0 on PB pins. This is new on A33, and is much better than using
R_UARTfor console on A23, as we can also see messages from BROM/boot0 when developing, and also use the same earlyprintk settings as other sunxi platforms.

Patch 2 adds a pinmux setting for 8 bit eMMC on mmc2. mmc2 also has a reset pin, though I'm not sure if our mmc driver actually uses it. Not using it seems to work anyway.
Patch 3 adds the dts file for the SinA33 dev board. Just the basic set of features are enabled: UART console, MMC, LRADC.
Cool stuff, looks good to me. Note I plan on adding support for the musb and usb-host on the A33 tonight, I've a 10" tablet which has both an otg and a host usb port.
I'm not sure if I'll post the series for this right away as I'm still waiting on some dependencies to get merged first, but keep an eye out on my sunxi-wip tree as something should show up there tonight (CET).
Regards,
Hans
