Add spidev to imx28

imravi — Sat, 10 Oct 2015 05:07:55 GMT

I am trying to add spidev to my linux-2.6.31 version applying the set of patch from freescale "imx_10.08.00.tar.bz2" . I have added the related data in the mach-mx28.c according to this image given by igorpadykov

But still spidev 1.0 is not coming the dev directory. With the latest distribution of ltib as per the spec file for linux-2.6.31 the patch set should be "imx_10.10.00.tar.bz2". but i am unable to download this file. Can anyone please give a link to this file. is it because of this old patch distribution.

You could use kernel 4.2 instead and add spidev support in your dts file.

Take a look at arch/arm/boot/dts/imx28-tx28.dtsi for an example.
