Ugh.. powerpc probably has CONFIG_ISA_DMA_API but not
CONFIG_VIRT_TO_BUS.
I'm looking for a fix now.

Doh... This patch is already in li
Tidy up this driver a bit.
v2: redo patch 4 based on suggestions from Alan Stern
H Hartley Sweeten (4):
usb: ohci-ep93xx: use devm_ioremap_resource()
usb: ohci-ep93xx: use platform_get_irq()
usb: ohci-ep93xx: use devm_clk_get()
usb: ohci-ep93xx: tidy up driver (*probe) and (*remove
Use devm_ioremap_resource() to make the code a bit cleaner and
simpler.

Use devm_clk_get() to make the code a bit cleaner and simpler.
This also fixes a bug where a clk_put() is not done if usb_add_hcd()
fails.

The memory resource used by this driver is ioremap()'d and the normal
read,write calls can be used instead of the __raw_* variants.
Also, remove the inline tag on the helper functions and let the compiler
decide if they are inlined.

The divisors needed to generate the SPI clock are calculated per

them in ep93xx_spi_setup().
