1) It looks like the correct entry in kilauea.dts file should be: 208 IIC1: i...@ef600500 { 209 compatible = "ibm,iic-405ex", "ibm,iic"; 210 reg = <ef600500 14>; 211 interrupt-parent = <&UIC0>; 212 interrupts = <7 4>; 213 #address-cells = <1>; 214 #size-cells = <0>; 215 }; 216 217 SPI0: s...@ef600600 { 218 /* compatible = "ibm,iic-405ex", "ibm,iic"; */ 219 compatible = "amcc,scp-405ex"; 220 reg = <ef600600 6>; 221 interrupts = <8 4>; 222 interrupt-parent = <&UIC0>; 223 }; 224 225 RGMII0: emac-rg...@ef600b00 { 226 compatible = "ibm,rgmii-405ex", "ibm,rgmii"; 227 reg = <ef600b00 104>; 228 has-mdio; 229 }; 230 231 EMAC0: ether...@ef600900 {
2) Right now the e.g. scp-dev.c is in drivers/scp directory in one of the internal release I have found, NOT in the e.g. 2.6.29. Additional comments: - Ideally the file should be moved to drivers/spi, like all other spi drivers. - Even in the internal release, the files do NOT compile properly, because of missing file, need CONFIG_PINE, etc [supp...@localhost linux]$ make uImage scripts/kconfig/conf -s arch/powerpc/Kconfig CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh CHK include/linux/compile.h CALL arch/powerpc/kernel/systbl_chk.sh CC drivers/scp/scp-dev.o drivers/scp/scp-dev.c:84:24: error: asm/ibm4xx.h: No such file or directory drivers/scp/scp-dev.c:705: error: 'scpdev_init' undeclared here (not in a function) make[2]: *** [drivers/scp/scp-dev.o] Error 1 make[1]: *** [drivers/scp] Error 2 make: *** [drivers] Error 2 [supp...@localhost linux] Q: Marri, what do we need to provide to Nathan French ?

I've added the below to the device tree (under plb/opb/): [nfre...@nfrench-laptop linux-2.6-denx]$ diff -C2 arch/powerpc/boot/dts/kilauea.dts spi.dts *** arch/powerpc/boot/dts/kilauea.dts 2009-05-05 15:56:16.000000000 -0700 --- spi.dts 2009-08-06 08:42:19.000000000 -0700 *************** *** 207,210 **** --- 207,221 ---- #size-cells = <0>; }; + + SPI0: s...@ef600600 { + cell-index = <0>; + compatible = "ibm,spi-405ex", "ibm,spi"; + reg = <ef600600 6>; + interrupts = <8 4>; + interrupt-parent = <&UIC0>; + mode = "cpu"; + }; RGMII0: emac-rg...@ef600b00 { I've also compiled my kernel with the following enabled: CONFIG_SPI=y CONFIG_SPI_MASTER=y CONFIG_SPI_SPIDEV=y I see this make it into the device tree after boot: [r...@10.2.3.28 /]$ find /proc/device-tree/ | grep spi /proc/device-tree/plb/opb/s...@ef600600 /proc/device-tree/plb/opb/s...@ef600600/name /proc/device-tree/plb/opb/s...@ef600600/mode /proc/device-tree/plb/opb/s...@ef600600/interrupt-parent /proc/device-tree/plb/opb/s...@ef600600/interrupts /proc/device-tree/plb/opb/s...@ef600600/reg /proc/device-tree/plb/opb/s...@ef600600/compatible /proc/device-tree/plb/opb/s...@ef600600/cell-index But I don't see any /dev/spidev* devices created or any mention of SPI at boot time. I'm starting to suspect that I don't have the kernel configured right, otherwise I would see at least the SPI driver complaining about something, right?
