Merge branch 'pcs-xpcs-cleanups-batch-2'

Russell King says:

====================
net: pcs: xpcs: cleanups batch 2

This is the second cleanup series for XPCS.

Patch 1 removes the enum indexing the dw_xpcs_compat array. The index is
never used except to place entries in the array and to size the array.

Patch 2 removes the interface arrays - each of which only contain one
interface.

Patch 3 makes xpcs_find_compat() take the xpcs structure rather than the
ID - the previous series removed the reason for xpcs_find_compat needing
to take the ID.

Patch 4 provides a helper to convert xpcs structure to a regular
phylink_pcs structure, which leads to patch 5.

Patch 5 moves the definition of struct dw_xpcs to the private xpcs
header - with patch 4 in place, nothing outside of the xpcs driver
accesses the contents of the dw_xpcs structure.

Patch 6 renames xpcs_get_id() to xpcs_read_id() since it's reading the
ID, rather than doing anything further with it. (Prior versions of this
series renamed it to xpcs_read_phys_id() since that more accurately
described that it was reading the physical ID registers.)

Patch 7 moves the searching of the ID list out of line as this is a
separate functional block.

Patch 8 converts xpcs to use the bitmap macros, which eliminates the
need for _SHIFT definitions.

Patch 9 adds and uses _modify() accessors as there are a large amount
of read-modify-write operations in this driver. This conversion found
a bug in xpcs-wx code that has been reported and already fixed.

Patch 10 converts xpcs to use read_poll_timeout() rather than open
coding that.

Patch 11 converts all printed messages to use the dev_*() functions so
the driver and devie name are always printed.

Patch 12 moves DW_VR_MII_DIG_CTRL1_2G5_EN to the correct place in the
header file, rather than amongst another register's definitions.

Patch 13 moves the Wangxun workaround to a common location rather than
duplicating it in two places. We also reformat this to fit within
80 columns.
