3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Felipe Balbi <balbi@xxxxxx> commit 1a947746dbe1486d0e305ab512ddf085b7874cb3 upstream. First of all, that 28 value makes no sense as HIRD threshold is a 4-bit value, second of all it's causing issues for OMAP5. Using 12 because commit cbc725b3 (usb: dwc3: keep default hird threshold value as 4b1100) had the intention of setting the maximum allowed value of 0xc. Also, original code has been wrong forever, so this should be backported as far back as possible.
