IOSF is the Intel On-chip System Fabric used in SOCs. IOSF SB is the IOSF SideBand message interface. This patch serializes IOSF SB access using both phy bits in the SWFW_SEMAPHORE register. It also adds a helper function to wait for IOSF SB accesses to complete. Use the new function to perform this wait before each access, as specified in the datasheet, in addition to using it to wait for IOSF SB read/write completion. Signed-off-by:
