| |
Hi Stephen.
I had some people ask me about a sdio userspace interface, and ran across the chdio.c file as found in the MSM android kernel trees:
https://android.googlesource.com/kernel/msm/+/57b74303d6f033ab04be039379f6661337fb9279
Any reason why this hasn't been submitted upstream? Or has it, and was it rejected?
Also, what userspace code uses this? Is there some android-specific code somewhere that does a weird mix of sysfs and char control of the hardware? And what type of SDIO devices are controlled with this?
thanks,
greg k-h
