Wait... so the mode register isn't supported? Does AM35x support any
accelerated modes?
Mode register is available though with some difference due to 15Rx/Tx
eps.
I have not added CPPI4.1 DMA specific register here..
Ah. Then they're not compatible with DA8xx anyway...
We could make it compatible with some change as done at,
http://arago-project.org/git/people/?p=sriram/ti-psp-omap.git;a=commitdiff;h=2ecce9529bd56c32997e0b2cbe84f7727ba5b217
I'm not sure where cppi41_dma.c gets the definitions for
USB_[RT]X_MODE_REG... anyway, I'm thinking of a different solution now,
i.e. moving the functions that access the implementation specific
acceleration
+#define USB_END_OF_INTR_REG 0x60
Hm, I don't see the generic RNDIS EP size registers also. So, generic
RNDIS mode isn't supported? Then cppi41_dma.c won't work with this
chip... :-/
Generic RNDIS mode is suported and CPPi4,1 is already verified to be
working on
AM3517.
I wonder how it can work as the registers cppi41_dma.c relies upon
are not the same as in DA8xx. Did you make some changes to cppi41_dma.c?
There were only few changes to make it work. You can see the changes
in our internal release tree at,
http://arago-project.org/git/people/?p=sriram/ti-psp-omap.git;a=summary
They have all the CPPI patches based out of your latest patch. All these
My latest was take 5, this tree has take 3 as a base.
have to be reviewed/cleaned which is not happening as the base CPPI4.1 patch
itself is pending to be merged.
Any update on CPPI4.1 driver location?
I'm pretty sure it should be in arch/arm/common/...
Are you still waiting for Russell's reply?
Well, yes and no. I'm not hoping on Russell's reply though but
haven't found time to move the code and post the new patch...
WBR, Sergei
