SDHCI driver for Tegra

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Olof,

I've been looking into getting mainline Linux better suited for developing
the ALSA driver. Specifically, 

git://android.git.kernel.org/kernel/tegra.git for-next

The primary thing I'm missing is an SDHCI driver. I notice that there is one
in linux-tegra-2.6.36, and a different version derived from that in
chromeos-2.6.37-rc5.

Can you elucidate me on the difference; what's missing or buggy in each,
which would be best to push upstream, etc.

BTW, I have the version from ChromeOS in my tree now, and it kinda works;
I'm able to boot ChromeOS without UI with it. That said, I'm getting a slew
of kernel error spew from it; perhaps because I had to comment out a couple
SDHCI quirks that don't appear to exist in for-next yet:

SDHCI_QUIRK_BROKEN_ADMA_ZEROLEN_DESC
SDHCI_QUIRK_NO_SDIO_IRQ

I haven't looked into that at all yet, but will soon.

[   11.985039] mmc2: ADMA error
[   11.988087] mmc2: Got data interrupt 0x02000000 even though no data operation was in progress.
[   11.996827] mmcblk0: retrying using single block read

Thanks!
