I wont be able to go to FOSDEM this year, i hope you will all have a good time.

My count of the people attending is 18. I may have missed some, but I got stuck at 16 or 17, but with 20 - 22 seats we should be okay :) We will leave Fosdem together by bus around 7pm, meeting point at 6H45 at the O'reilly books stand in the H hall. I know the tram takes special tram-passes. What is the easiest/cheapest way to get this for the group/a few? Payment isn't the issue I would expect. You do have magnetic cards (vs rfid ones) for 10 trips for 12EUR I think. You just have to pass the card multiple times according to the number of people traveling. It is better to take the bus 71 down to Debroukere, because the bus stop is not that far away from the restaurant.

Re: [linux-sunxi] Wiki broken
I did a reboot on the mail server yesterday, maybe you did a change exactly when the server was rebooting. So the php was not able to connect to the server.

Re: [linux-sunxi] Re: Passing the platform data for SPI device
Why dont you just add the device to the fex file ??
activate your spix_para parameters
and add something like:
|[spi_devices]|
spi_dev_num=1
|[spi_board0]|
|modalias| |= |||mcp251x
|max_speed_hz| |= ||1200|
|bus_num| |= ||1|
|chip_select| |= ||0|
|mode| |= ||3|
|full_duplex| |= ||0|
|manual_cs| |= ||0|
With spidev it works well with modalias spidev.

Hi All,
I'm trying to use some SPI devices on A10s OLinuXino. It was flawless for
simple MCU driven by spidev (everything needed is defined in FEX). Now I'm
trying to connect external CAN over SPI (MCP2515).
The mcp251x driver needs to pass oscillator frequency through the
mcp251x_platform_data structure. Is there any clean way how to do it on 3.4
linux-sunxi? It seems that platform data for SPI board aren't passed by sunxi
SPI driver.
I'm using Debian image with custom built 3.4.61 linux-sunxi.
Thanks to all,

Re: [linux-sunxi] Re: Passing the platform data for SPI device
I'm sorry, i didnt see you needed that.
you can use on of the script parse functions to get the oscilator
frequency value from the fex.
Of course you will have to change the spi src as vinicius said.

yes, this is exactly what I did. I was trying both spidev and mcp251x. There
is no problem with spidev (it is currently working) but for mcp251x I need to
pass (very simple) platform data with oscillator frequency. The mcp251x is
being initialized during boot but it fails because of missing platform data.
I don't know if there is some clean way how to pass platform data
of the mcp251x driver. I think that FEX is not able to do that (there is no
handling in sunxi spi).
Thanks for you answer,
Tomas
