EIM support (via imx-weim) with devicetree on 3.14.28

On the 3.0.35 kernel with 6sl, we were able to get EIM
working quite easily using the board code to setup and support EIM via
userspace remap. On 3.14.28, I've been hitting some messy problems. Currently,
I've got my devicetree changes for the EIM pins done and they compile fine, but
it looks like the imx-weim driver does not support 6sl.

 

I noticed in one of the forum posts from May 2016, an FSL support
person said: https://community.nxp.com/thread/386593

"

  1. i.MX6SL BSP device tree file does not have EIM definitions
    as it uses default

CCM settings, check i.MX6SL dts file (arch/arm/boot/dts/imx6sl.dtsi)
:

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/boot/dts/imx6sl.dtsi?h=imx_3.14.52_1.1.0_ga

arch/arm/mach-imx/clk-imx6sl.c :

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-imx/clk-imx6sl.c?h=imx_3.14.52_1.1.0_ga

If needed, it may be suggested to request through fae
additional patch to provide EIM

support in dts of i.MX6SL BSP.

I'm interested in the last part where he said there is an
additional patch to provide EIM support in devicetree for 6sololite. Is this
something we can get access to?

 

Thanks,
