This is a single register which is 16-bit wide, can you also add a 
comment to that extent like what is done for other register definitions?
+#define B53_BROADSYNC_TS_REPORT_CTRL	0x02
+#define B53_BROADSYNC_PCP_CTRL		0x03
+#define B53_BROADSYNC_MAX_SDU		0x04
+#define B53_BROADSYNC_TIMEBASE1		0x10
Single register which is 32-bit wide, no need to define the 
TIMEBASE1..4, just call it timebase.
+#define B53_BROADSYNC_TIMEBASE2		0x11
+#define B53_BROADSYNC_TIMEBASE3		0x12
+#define B53_BROADSYNC_TIMEBASE4		0x13
+#define B53_BROADSYNC_TIMEBASE_ADJ1	0x14
Likewise.

Likewise, 32-bit register.
+#define B53_BROADSYNC_SLOT_ADJ1		0x1c
+#define B53_BROADSYNC_SLOT_ADJ2		0x1d
+#define B53_BROADSYNC_SLOT_ADJ3		0x1e

+#define B53_BROADSYNC_LINK_STS1		0xe0
+#define B53_BROADSYNC_LINK_STS2		0xe1
Likewise this is a 16-bit register.
