Re: [U-Boot] [PATCH 3/4 v5] DA8xx: Add MUSB host support
Hi, 2009/12/21 Gupta, Ajay Kumar ajay.gu...@ti.com: Remy, How about USB patches from me supporting MUSB on DA8xx platform? Okay let's check... 2009/11/17 Gupta, Ajay Kumar ajay.gu...@ti.com: Remy, Any comment on DA8xx USB support patches? These patch set depends on DA8xx base support patches which are available only on uboot-ti tree. The last time I checked this series was not mainlined. Is it now? It is always fun with these dependencies to other repos.. ;-) If the series can be applied to current mainline, I will take them in...

I believe it is in u-boot master as of now http://git.denx.de/?p=u-boot.gita=searchh=HEADst=commits=DA8xx It takes time for stuff in u-boot-ti to go to u-boot as we have an intermediate u-boot-arm :-) We are doing things the way it is supposed to be done though :-) The last time I checked this series was not mainlined. Is it now? So I believe It is always fun with these dependencies to other repos.. ;-) If the series can be applied to current mainline, I will take them in... This I cannot confirm as the base patches were itself were going through a process of review at that point of time. Right.
