Subject: [RFC PATCH v2 0/9] wii: add usb 2.0 support
Date: Sun, 28 Feb 2010 15:07:53 +0100 [thread overview]
Message-ID: <1267366082-15248-1-git-send-email-albert_herranz@yahoo.es> (raw)
The following patch series adds USB 2.0 support for the Wii PowerPC
platform via the EHCI controller present in the "Hollywood" chipset
of the video game console.
v1 -> v2
- enable per-device DMA coherent support on the Wii
- add a generic dmabounce based on ARM dmabounce
- make PowerPC and ARM use the generic dmabounce support
(ARM just compile-tested)
- do not bounce buffers at the USB layer
- handle bounce buffers on the Wii at the platform support layer via the
DMA API
- introduce a flag HCD_NO_COHERENT_MEM to avoid using coherent memory for
USB buffers
- make the "Hollywood" EHCI controller use HCD_NO_COHERENT_MEM and honor
MEM2 DMA constraints to solve the platform restrictions accessing
coherent memory.
Albert Herranz (9):
powerpc: add per-device dma coherent support
wii: have generic dma coherent
dma-coherent: fix bitmap access races
add generic dmabounce support
arm: use generic dmabounce support
powerpc: add optional per-device dmabounce support
wii: add mem2 dma mapping ops
USB: add HCD_NO_COHERENT_MEM host controller driver flag
wii: hollywood ehci controller support
