Hi Per..
it is interesting approach..so
we want to test your double buffering in our environment(Samsung SoC).
Did you test with SDHCI?
So far I have only tested on mmci for board u5500 and u8500. I happily

Hi Will.
I have some question...i'm testing dw_mmc in our environment.
but i didn't understand pdata-init(?)...what initialize in there?
In most of our platforms init is empty so I guess it would be fine to
change
I'm also worried about this patch not taking in account the 8 clock cycles
before
shutting down the clock, contrary to the clock gating fw.
If you power down hc, you will also gate the clock. So the sdio protocol
might not be
strictly followed.
As mmc spec said, 8 clock cycles is
This patch series adds support for ADMA on MMC1 MMC2 controllers on OMAP4.
There is no performance improvement observed using ADMA over SDMA.
Advantage using ADMA could be reducing contention over SDMA.
Also the series includes some cleanup.
The series is based on 2.6.37-rc8 and tested on
OMAP4 introduces dedicated internal DMA which is ADMA for its MMC
controllers HSMMC1 HSMMC2.
Renaming use_dma member of the struct omap_hsmmc_host to xfer_type
and defining the transfer modes PIO/SDMA/ADMA that can be used by the
MMC controller.

Renaming omap_hsmmc_dma_cleanup as omap_hsmmc_xfer_cleanup and doing some
cleanup by handling the error success scenarios during a transfer for
different xfer_type.

On OMAP4, MMC1 MMC2 controllers support ADMA feature which will
provide direct access to internal data.
Basically ADMA is a DMA controller embedded in the MMC controller.
It fetches each descriptor line [address+length+attributes] from a
descriptor table and executes the corresponding action

Hi,
I am currently interested in the read performance of the SDHI driver. I
