      netlink: Remove netlink_compare_arg.trailer · 8f2ddaac
      由 Herbert Xu 提交于 
      Instead of computing the offset from trailer, this patch computes
netlink_compare_arg_len from the offset of portid and then adds 4
to it.  This allows trailer to be removed.

      Merge branch 'netcp-next' · 69a3b16f
      由 David S. Miller 提交于 
      Murali Karicheri says:

====================
NetCP: Add support for version 1.5

NetCP 1.5 is used in newer K2 SoCs from Texas Instruments
such as K2E, K2L etc. This patch series add support for Ethss
driver for this version of NetCP. While at it, fix couple of
bugs in the original driver.

One of the earlier patch "net: netcp: select davinci_mdio driver
by default" is folded onto this series.

Please review and let me know your comments.

      net: netcp: ethss: enhancement to support NetCP 1.5 ethss · 9a391c7b
      由 WingMan Kwok 提交于 
      NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.

To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.

      net: netcp: use separate reg region for individual ethss modules · 21e0e0dd
      由 Karicheri, Muralidharan 提交于 
      Ethss has multiple modules within the sub system
 - switch sub system
 - sgmii
 - mdio
 - switch module

NetCP driver re-uses existing davinci mdio driver. It requires to
have its own register region to map the reg space. So restructure
the code to use separate reg region for the individual modules it
manages. Use range property to define register space of NetCP and
use reg property to define individual reg spaces. So MDIO will have
its own reg space to map. This is a pre-requisite to enable MDIO
driver for NetCP.
