Hi,
grepping for tdi (arc/chipidea/mips otg ehci like controller)
registers in driver/usb/gadget show interesting things : it seems we
have 4 drivers for handling the same controller.
- fsl_udc_core [1]
- ci13xxx_udc [2]
- mv_udc [3]
- langwell [4]
fsl is the historic driver (freesale and tegra will be using it).
ci13xxx was added by mips and msm chip use it
mv_udc/langwell is newer.
I didn't look at the driver in details, there may be tiny difference
between all this controllers.
Shouldn't we try to merge them and rename to a clear name in order
people don't rewrite again the same driver ?
Sure, if you think it is possible, please do so.
But without help of the current maintainers it will be difficult. I have
no way to test on their platform.
Also how to select which driver should be the base of the merge :
- fsl_udc_core is the historic driver and seems to have tested pretty
well (and was used on big endian arch)
- langwell_udc seems the most active one.
