[linux-sunxi] Converting script.bin to device tree file

Is there a straightforward way to convert a script.bin file to a device tree file? Any HOWTO that maps the various options? Should I first be experimenting with the sunxi Uboot instead of Mainline? My device has an AXP152 paired with an A20. Looking at Mainline U-boot, this is an unexpected

[linux-sunxi] Enable Pull-Up on gpio when accessed through sysfs?

Hi all, I want to enable the pull-up resistors for some gpio pins on a BananaPi-R1 when the pins are accessed from user space through /sys/class/gpio/. Therefore I have added the following to the pio node of the device tree: { ... switch3: switch3@0 { allwinner,pins = "PI20";

[linux-sunxi] [RFC 1/2] spi: sunxi: Add Allwinner A23/A33 support to spi-sun6i

The Allwinner A23/A33 SoCs contain an SPI controller that is largely identical to the one in the A31. The major differences from A31 to A23/A33 are: - The TX and RX FIFOs on the A23/A33 are only 64 Bytes deep compared to 128 Bytes on the A31. - On A23/A33, the SPI_INTCTL register provides an

[linux-sunxi] [RFC 0/2] A33 SPI support

Hello everybody, during the mainlining discussion in the Olimex blog at https://olimex.wordpress.com/2016/08/30/free-electrons-add-mainline-linux-kernel-support-for-the-a13-allwinner-vpu/#comments the topic of A33 SPI support came up. Chen-Yu and Siarhei have pointed out that the chances are

[linux-sunxi] [RFC 2/2] ARM: dts: sun8i: Add SPI support to the Allwinner A23/A33 dtsi.

Define the necessary nodes in the A23/A33 dtsi files to make the SPI0 controller accessible. The SoCs also have a secondary SPI controller (SPI1), but it cannot be muxed to any available pins and therefore doesn't get included in the dtsi. Signed-off-by: Karsten Merker ---

Re: [linux-sunxi] Converting script.bin to device tree file

I think there is a tool from Allwinner in their more recent releases for mapping fex to device tree. In here somewhere... https://gitlab.com/pine64-android/tools/tree/master when you go through the pack step it prints out a bunch of messages on how it is doing the mapping. I have not looked at
