Added additional information for type and compatibility strings and interrupt information to the SDRAM0 memory-controller device tree nodes for AMCC PowerPC 405EX[r]-based boards to facilitate binding with the new "ibm,sdram-4xx-ddr2" EDAC memory controller adapter driver. Signed-off-by: Grant Erickson <redacted> --- As support in the associated EDAC adapter driver is added over time, similar changes will/should be made to the DTS files for boards leveraging realizations of this "ibm,sdram-4xx-ddr2" controller, including the 440SP, 440SPe, 460EX, 460GT and 460SX. Patch v2, based on review from David Gibson, removes the 'device_type' field because it is only used for legacy OpenFirmware method interfaces and no such compatibility is warranted here. In addition, removed address- and size-cells as this node has no children. arch/powerpc/boot/dts/haleakala.dts | 8 +- arch/powerpc/boot/dts/kilauea.dts | 8 +- arch/powerpc/boot/dts/makalu.dts | 8 +- 3 files changed, 21 insertions(+), 3 deletions(-)diff --git a/arch/powerpc/boot/dts/haleakala.dtsb/arch/powerpc/boot/dts/haleakala.dts index 513bc43..64880ab 100644--- a/arch/powerpc/boot/dts/haleakala.dts +++ b/arch/powerpc/boot/dts/haleakala.dts@@ -89,8 +89,14 @@ clock-frequency = <0>; /* Filled in by U-Boot */ SDRAM0: memory-controller { - compatible = "ibm,sdram-405exr"; + compatible = "ibm,sdram-405exr", "ibm,sdram-4xx-ddr2"; dcr-reg = <0x010 0x002>; + #interrupt-cells = <1>; + interrupt-parent = <&SDRAM0>; + interrupts = <0x0 0x1>; + interrupt-map = </* ECCDED Error */ 0x0 &UIC2 0x5 0x4 + /* ECCSEC Error */ 0x1 &UIC2 0x6 0x4>; + interrupt-map-mask = <0xffffffff>;When all interrupts are mapped the same parent, this should do as well: interrupt-parent = <&UIC2>; interrupts = <0x5 0x4 /* ECCDED Error */ 0x6 0x4>; /* ECCSEC Error */ Other than this: Acked-by: Stefan Roese <sr@denx.de>
Yeah, I agree. Adding an interrupt map when it's not needed is just complexity that doesn't need to be there. josh
