Revision 4c116e1ae43955a0a38555dfd4d136a222a8996b authored by Matt Roper on 28 February 2020, 00:43:20 UTC, committed by Jani Nikula on 02 March 2020, 08:48:56 UTC
We need to explicitly set the TLB Request Timer initial value in the
BW_BUDDY registers to 0x8 rather than relying on the hardware default.
v2: Apply missing REG_FIELD_PREP to ensure 0x8 is placed in the correct
bits during the rmw. (Jose)
