I completely read this wrong the first time... The common meaning of
#defines line this is

VEND1_GLOBAL_CFG_ is the register and what follows indicates some bits
in the register.

However, this is not true here, these are all registers. Maybe add
_REG to the end? It makes them different to other defines for
registers, but if i parsed it wrong, probably other will as well?

How about a comment like

/* The following registers all have similar layouts; first the registers... */
#define VEND1_GLOBAL_CFG_10M 0x0310
...
/* ... and now the fields */
#define VEND1_GLOBAL_CFG_RATE_ADAPT GENMASK(8, 7)

static int aqr107_read_rate(struct phy_device *phydev)
{
int val;
+ u32 config_reg;

Revere Christmass tree. config_reg should be first.

OK
