Dear Tom Rini,
From: Pankaj Bharadiya pankaj.bharadiya@ti.com
The endpoint rx count register value will be zero if it is read before receive packet ready bit (PERI_RXCSR:RXPKTRDY) is set.
Check for the receive packet ready bit (PERI_RXCSR:RXPKTRDY) before reading endpoint rx count register. Proceed with rx count read and FIFO read only if RXPKTRDY bit is set.
As this makes the function fit less-well within 80 columns, use __func__ in some debug statements rather than __PRETTY_FUNCTION__ as they are identical for C programs.
I'd say this is TI stuff, so let's push it through TI tree (both the musb patches please).
Best regards, Marek Vasut
