Dear Ilya Yanok, > Current MUSB driver in U-Boot uses old UDC API while new gagdet > client drivers need new gadget API. Also current MUSB driver has > some significant limitations (like inability to handle tx for > endpoints other than ep0). So I think port of new Linux driver is > desirable. > > This is initial port, performed mostly by putting DM and OTG > code under #ifndef __UBOOT__ clauses. My intention was to be as > close as possible to the original to ease of possible resyncs. > Some warnings are suppressed via CFLAGS. There are some style > problems but I'm not touching them for now for the above mentioned > reason. There is obviously some room for optimisation, some > structure fields are unused as well as (probably) some code. > > This is not a replacement for existing MUSB driver (at least for > now), cause there are still consumers of USB serial gadget which > uses old API and there is no support for serial with new API > for now. > > OTG and DMA are not supported. Ported drivers include: > musb_dsps (should work both with TI AM33xx and TI81xx, tested only on > AM33xx), am35x (tested on AM3517 EVM) and omap2plus (should work on > OMAP2/3/4, tested on omap3_beagle, omap4_panda doesn't work and needs > more work). Others should be easy to port too. > > Virtual root hub is not implemented but this shouldn't be > a big problem as the old code has virtual root hub support > enabled only for Blackfin platform. > > Pathes are rather big because of the original code size (and I didn't > delete unused code, just disabled it).

Hopefully it will be also useful > if resync with the kernel will be needed in future. > > [1] https://github.com/yanok/u-boot/tree/musb-changes-from-linux-v4 [...]
What is this patchset ? I received another similar one, but which is more complete ... _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
