The MFC nodes with the memory regions reserved for memory allocations are missing in the Exynos5420 Peach Pit and Exynos5800 Peach Pi DTS. This causes the s5p-mfc driver probe to fail with the following error: [ 4.140647] s5p_mfc_alloc_memdevs:1072: Failed to declare coherent memory for MFC device [ 4.216163] s5p-mfc: probe of 11000000.codec failed with error -12 Add the missing nodes so the driver probes and the {en,de}coder video nodes are registered correctly: [ 4.096277] s5p-mfc 11000000.codec: decoder registered as /dev/video4 [ 4.102282] s5p-mfc 11000000.codec: encoder registered as /dev/video5 Signed-off-by: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx> --- arch/arm/boot/dts/exynos5420-peach-pit.dts | 5 +++++ arch/arm/boot/dts/exynos5800-peach-pi.dts | 5 +++++ 2 files changed, 10 insertions(+) diff --git a/arch/arm/boot/dts/exynos5420-peach-pit.dts b/arch/arm/boot/dts/exynos5420-peach-pit.dts index b644858231b6..f9d2e4f1a0e0 100644 --- a/arch/arm/boot/dts/exynos5420-peach-pit.dts +++ b/arch/arm/boot/dts/exynos5420-peach-pit.dts @@ -694,6 +694,11 @@ status = "okay"; }; +&mfc { + samsung,mfc-r = <0x43000000 0x800000>; + samsung,mfc-l = <0x51000000 0x800000>; +}; + &mmc_0 { status = "okay"; num-slots = <1>; diff --git a/arch/arm/boot/dts/exynos5800-peach-pi.dts b/arch/arm/boot/dts/exynos5800-peach-pi.dts index 6ba9aec15485..62ceb89e073f 100644 --- a/arch/arm/boot/dts/exynos5800-peach-pi.dts +++ b/arch/arm/boot/dts/exynos5800-peach-pi.dts @@ -669,6 +669,11 @@ status = "okay"; }; +&mfc { + samsung,mfc-r = <0x43000000 0x800000>; + samsung,mfc-l = <0x51000000 0x800000>; +}; + &mmc_0 { status = "okay"; num-slots = <1>; -- 2.5.5 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
