Add TODO file for DWC2 driver Signed-off-by: Paul Zimmerman <paulz@xxxxxxxxxxxx> --- Greg, this should be applied after the microframe scheduler patch, since it assumes that one has already been applied. drivers/staging/dwc2/TODO | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 drivers/staging/dwc2/TODO diff --git a/drivers/staging/dwc2/TODO b/drivers/staging/dwc2/TODO new file mode 100644 index 0000000..282470d --- /dev/null +++ b/drivers/staging/dwc2/TODO @@ -0,0 +1,33 @@ +TODO: + - Dan Carpenter would like to see some cleanups to the microframe + scheduler code: + http://www.mail-archive.com/linux-usb@xxxxxxxxxxxxxxx/msg26650.html + + - Should merge the NAK holdoff patch from Raspberry Pi + (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands + that patch is incomplete, it needs more investigation to see if it + can be made to work for non-Raspberry Pi platforms that lack the + special FIQ interrupt that the Pi has. Without this patch, the driver + has a high interrupt rate (8K/sec). + + - The Raspberry Pi platform needs to have support for its FIQ interrupt + added, to get the same level of functionality as the downstream + driver. The raspberrypi.org developers have indicated they are + willing to help with that. + + - Some of the default driver parameters (see 'struct dwc2_core_params' + in core.h) won't work for many platforms. So DT attributes will need + to be added for some of these. But that can be done as-needed as new + platforms are added. + + - Eventually the driver should be merged with the s3c-hsotg peripheral + mode driver, so that both modes of operation can be supported with a + single driver. But I think that can wait till after the driver has + been moved to mainline. + + - After that, OTG support can be added. I'm not sure how much demand + there is for that, though, so I have that as a low priority. + +Please send any patches for this driver to Paul Zimmerman <paulz@xxxxxxxxxxxx> +and Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>.
