  • 3dbdb4dd4   video: ipu: fix out of bounds access ... Browse Code »

    We need to access reg stp_rep9, but not stp_rep[(9 - 1) / 2].
    If using "__raw_writel(0, DI_STP_REP(disp, 9))", this will exceeds
    the size of stp_rep array.

    Simplify if/else code, since if channel equals to MEM_BG_SYNC or
    MEM_FG_SYNC, we have value 5 for 'dc_chan'.

  • 3e780af12   video: ipu_disp: remove pixclk fixup ... Browse Code »

    The ipu display insists on having a lower_margin smaller
    then 2. If this is not the case it will attempt to force
    it and adjust the pixclk accordingly. This multiplies pixclk
    in Hz with the width and height, since this is typically
    a * 10^7 * b * 10^2 * c * 10^2 this will overflow the
    uint_32 and make things even worse. Since this is a
    bootloader and the adjustment is neglectible, just force
    it to two and warn about it.

  • e6e9cff2d   video: ipu_disp: squash clang warning ... Browse Code »

    Since rgb2ycbcr_coeff and friends are declared const, but assigned
    to a void pointer, clang will warn that the const is implicity casted
    away. If the pointer is changed to void const * gcc will warn when it
    is implicitly casted to a const int array. Just add a correctly
    typed pointer instead to prevent these casts and hence the warnings.

  • e66866c54   video: ipu_disp: wait for DP SF end irq when disabling sync BG flows ... Browse Code »

    Instead of waiting for DC triple buffer to be cleared, this patch
    changes to wait for a relevant DP sync flow end interrupt to come
    when disabling sync BG flows. In this way, we align the implement
    to the freescale internal IPUv3 driver. After applying this patch,
    an uboot hang up issue at the arch_preboot_os() stage, where we
    disable a relevant ipu display channel, is not observed any more on
    some MX6DL platforms.

  • 2740e5de4   video: ipu_disp: Fix clock polarity logic ... Browse Code »

    Currently the HDMI splash screen image quality on mx6solo does not show a
    very stable image.

    By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP,
    we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit.

    >From FSL BSP [1] we have:

    if (!sig.clk_pol)
    di_gen |= DI_GEN_POLARITY_DISP_CLK;

    Applying the same logic into U-boot fixes the HDMI image stability.

  • 575001e40   MX51: Add IPU driver for video support ... Browse Code »

    The patch is a porting of the IPU Linux driver
    developed by Freescale to have framebuffer
    functionalities in u-boot. The port is based on
    kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f,
    as delivered by Freescale [i.MX BSP].
    Most features are dropped from the original driver and
    only LCD support is the goal of this porting.
