Hi
I am working on DM6446 evolution board
I am facing problem with musb with tha latest kernel (2.6.28.7)
musb drivers is registered successfully but it does not detect any client and
hence mouce, keyboard does not work
I have not made any changes in the musb code (using the default that comes with
the kernel). and musb_platform_init function from davinci.c looks fine..
isr that is davinci_interrupt is also fine.
I am using this driver in PIO mode. I have the same problem with DMA mode
In the musb_probe function the base address was obtained using following code
base = ioremap(iomem->start, iomem->end - iomem->start + 1);
if (!base) {
dev_err(dev, "ioremap failed\n");
return -ENOMEM; }
The base address obtained from this code was not correct and used to give me
the No device found error
so I have hardcoded this value to 0xc8060000.
This works for me
here is the log of kernel messages..
