From 2434bbb30e79468c49cff3cff6005236f55ed188 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sun, 30 Nov 2008 18:53:40 +0000 Subject: powerpc: Fix dma_map_sg() cache flushing on non coherent platforms On PowerPC 4xx or other non cache-coherent platforms, we lost the appropriate cache flushing in dma_map_sg() when merging the 32 and 64-bit DMA code (commit 4fc665b88a79a45bae8bbf3a05563c27c7337c3d, "powerpc: Merge 32 and 64-bit dma code"). This restores it.

Fix this by moving the MCU node into the I2C controller node. The original patch[1] was OK though. ;-) Signed-off-by: Anton Vorontsov Signed-off-by: Kumar Gala --- arch/powerpc/boot/dts/mpc8349emitx.dts | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/arch/powerpc/boot/dts/mpc8349emitx.dts b/arch/powerpc/boot/dts/mpc8349emitx.dts index 2c9d54a..4bdbaf4 100644 --- a/arch/powerpc/boot/dts/mpc8349emitx.dts +++ b/arch/powerpc/boot/dts/mpc8349emitx.dts @@ -91,6 +91,14 @@ interrupts = <18 0x8>; interrupt-parent = <&ipic>; }; + + mcu_pio: mcu@a { + #gpio-cells = <2>; + compatible = "fsl,mc9s08qg8-mpc8349emitx", + "fsl,mcu-mpc8349emitx"; + reg = <0x0a>; + gpio-controller; + }; }; spi@7000 { @@ -139,14 +147,6 @@ interrupt-parent = <&ipic>; interrupts = <71 8>; }; - - mcu_pio: mcu@a { - #gpio-cells = <2>; - compatible = "fsl,mc9s08qg8-mpc8349emitx", - "fsl,mcu-mpc8349emitx"; - reg = <0x0a>; - gpio-controller; - }; }; usb@22000 { -- cgit v1.1
