[PATCH 0/8] ARM: mach-shmobile: armadillo800eva: USB/SDHI/MMIF support patch set

[Kuninori Morimoto]

Hi Rafael, Magnus
Cc Simon

These are incremental patch set for armadillo800eva.

Kuninori Morimoto (8):
      ARM: mach-shmobile: clock-r8a7740: add USB clock
      ARM: mach-shmobile: clock-r8a7740: add SDHI clock
      ARM: mach-shmobile: clock-r8a7740: add MMCIF clock
      ARM: mach-shmobile: armadillo800eva: add USB function support
      ARM: mach-shmobile: armadillo800eva: add SDHI0 support
      ARM: mach-shmobile: armadillo800eva: add SDHI1 support
      ARM: mach-shmobile: armadillo800eva: add MMCIF support
      ARM: mach-shmobile: r8a7740: Reserve DMA memory for the frame buffer

This patch set include v3 of USB support.
Some R8A7740 clocks, for example, SUB/SPU/CEU/ clocks, use "usb24s" clock as parent.
"usb24s" clock is parent clock of "usb24", and this "usb24" is the main clock for USB.
These are very confusing naming, but based on R8A7740 chip datasheet.

#5 support SDHI0, but it use polling mode.
Because CD (Êrd Detect) pin didn't connected to SDHI0_CD pin, but connected IRQ31.
We can use IRQ31 for CD, but it needs chattering removal operation.
So, I selected very simple solution (= polling mode).
But polling mode is very enough at this point.

If you use USB function, please select

CONFIG_USB_RENESAS_USBHS=y
CONFIG_USB_RENESAS_USBHS_UDC=y

and select USB Gadget driver.
I used CONFIG_USB_ETH for test.

And set SW1.6 ON, then you can use CN24.

# insmod g_ether.ko
# ifconfig usb0 xxx.xxx.xxx.xxx up


Best regards

Patches [1-3/8] applied to the r8a7740 branch of the renesas.git tree.
However, I had to handle several merge conflicts with the FSI clock patch
applied previously, so please check if everything is correct in the tree.

Patches [4-8/8] applied to the armadillo800eva branch of the renesas.git tree,
on top of the r8a7740 branch.

Thanks,
Rafael

Thank you for accepting these.
I checked it, and it seems OK.
