I had exactly the same problem. It looks like the struct omap_mcbsp array was
intended to be accessible
>From include/plat/mcbsp.h
extern struct omap_mcbsp **mcbsp_ptr;
I couldn't get access to mcbsp_ptr in an out of tree module. So I added this
arch/arm/plat-omap/include/plat/mcbsp.h
+struct omap_mcbsp* omap_mcbsp_get_mcbsp_ptr(u8 id);
arch/arm/plat-omap/mcbsp.c
+struct omap_mcbsp* omap_mcbsp_get_mcbsp_ptr(u8 id)
+{
+ if (!omap_mcbsp_check_valid_id(id))
+ return NULL;
+
+ return id_to_mcbsp_ptr(id);
+}
+EXPORT_SYMBOL(omap_mcbsp_get_mcbsp_ptr);
+
This was to could get access to .phys_base and .dma_rx_sync for my own DMA ops.
Is there a better way?
