Other Parts Discussed in Thread: TLC59108

HI,

I have a omap4430 based board to which want to interface a mipi based lcd ssd2828. I am not able to find the linux driver for the ssd2828 from stable linux source.

Can any one help me to interface it.

I am using the variscite based omap4430 board.

source code being used is 3.8 kernel

Regards,

sainath

    Hi Sainath,

    Linux kernel updates regarding OMAP4 are ceased, I'm afraid.

    You can adopt one of those unsable drivers, i.e. https://github.com/omegamoon/Rockchip-GPL-Kernel/blob/master/drivers/video/rockchip/transmitter/ssd2828.c, add the driver to your board file/device tree, and work around the issues, if any.  

    If you post any specific issue here, our team can provide some pointers...  Otherwise you can contact some of the TI OMAP partners (SW Desigh houses listed here http://www.ti.com/lit/ml/sprw250/sprw250.pdf )  for integrating the sssd2828 display driver to your linux kernel release.

    Best Regards,

    Sainath,

    Since there is no kernel release with dts file for OMAP4, in order to understand what should be done regarding your display in the DTS file, I suggest to download android kernel 3.8.13 for the newer TI platforms (DRA7xx):
    git clone git://git.omapzoom.org/kernel/omap.git kernel/android-3.8
    cd kernel/android-3.8
    git checkout 7e6408234000c6526dae3f55c851adbcaae2d9ef
    When cloning is finished apply the following patches: http://omappedia.org/wiki/6AK.1.2_Application_Notes#Rev-G_10.22_Display_.28J6_Only.29

    Then you can open dra7xx-evm.dts file & search for the lg101, tlc59108 controller, display related configs in i2c nodes & display interfaces nodes, in order to get the idea of what should be included in your device tree.

    Hope this helps.

    Best Regards,
    Yordan
