We have a number of unused flags defined today and since we are scarce
on space and may need to introduce new flags in the future remove and
shift every existing flag down into a contiguous assignment. No
functional change.

Good to see some of the dev_flags go away!
PHY_BCM_FLAGS_MODE_1000BX is used just from broadcom.c, therefore it can
probably be moved to a structure in phydev->priv.
PHY_BRCM_STD_IBND_DISABLE, PHY_BRCM_EXT_IBND_RX_ENABLE and
PHY_BRCM_EXT_IBND_TX_ENABLE are set by
drivers/net/ethernet/broadcom/tg3.c but not used anywhere.

The next step would be to move it to a private flag, indeed.

That's right, tg3 drove a lot of the Broadcom PHY driver changes back
then, I also would like to rework the way we pass flags towards PHY
drivers because tg3 is basically the only driver doing it right, where
it checks the PHY ID first, then sets appropriate flags during connect.

Why does the tg3 controller need to enable the auto power down PHY
feature in the first place and the PHY driver can't just enable it by
itself?

That would be a question for Michael if he remembers those details from
12 years ago.

When support for optionally disabling the TXC was introduced, bit 2 was
used to do that operation but the datasheet for 50610M from 2009 does
not show bit 2 as being defined. Bit 8 is the one that allows automatic
disabling of the RXC/TXC auto disabling during auto power down.

We may have a problem here, with the layout of the Spare Control 3
register not being as universal as we think.
Your finding may have been the same as Kevin Lo's from commit
b0ed0bbfb304 ("net: phy: broadcom: add support for BCM54811 PHY"),
therefore your change is making BCM54XX_SHD_SCR3_TRDDAPD ==
BCM54810_SHD_SCR3_TRDDAPD, so currently this if condition is redundant
and probably something else is wrong too:
if (phydev->dev_flags & PHY_BRCM_DIS_TXCRXC_NOENRGY) {
if (BRCM_PHY_MODEL(phydev) == PHY_ID_BCM54810 ||
BRCM_PHY_MODEL(phydev) == PHY_ID_BCM54811)
val |= BCM54810_SHD_SCR3_TRDDAPD;
else
val |= BCM54XX_SHD_SCR3_TRDDAPD;
}
I'm not sure what "TRDD" stands for, but my copy of the BCM5464R
datasheet shows both bits 2 as well as 8 as being reserved. I have
"CLK125 Output" in bit 0, "DLL Auto Power-Down" in bit 1, "SD/Energy
Detect Change" in bit 5, "TXC Disable" in bit 6, and that's about it.
But I think it doesn't matter what BCM5464R has, since this feature is
gated by PHY_BRCM_DIS_TXCRXC_NOENRGY.

Let me go back to the datasheet of all of the PHYs supported by
bcm54xx_adjust_rxrefclk() and make sure we set the right bit.
I also have no idea what TRDD stands for.

Yes, but it should be working nonetheless.

I really don't know what the situation is with the 50610 and 50610M and
the datasheet appears to reflect that the latest PHYs should be revision
3 or newer (which we explicitly check for earlier), and that bit 8 is
supposed to control the disabling of RXC/TXC during auto-power down. I
can only trust that Matt checked with the design team back then and that
the datasheet must be wrong (would not be an isolated incident), let's
try not to fix something that we do not know for sure is broken.
I will respin without this patch and with another clean up added.

BCM54210E/BCM50212E has been verified to work correctly with the
auto-power down configuration done by bcm54xx_adjust_rxrefclk(), add it
to the list of PHYs working.
