Subject: [PATCH] net: add devm version of alloc_etherdev_mqs function
|
||||
|
||||
This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
|
||||
macro. These can be used for simpler netdev allocation without having to
|
||||
care about calling free_netdev.
|
||||
|
||||
Thanks to this change drivers, their error paths and removal paths may
|
||||
get simpler by a bit.

Subject: [PATCH 1/3] net: bgmac: allocate struct bgmac just once & don't copy
|
||||
it
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8

|
||||
|
||||
So far were were allocating struct bgmac in 3 places: platform code,
|
||||
bcma code and shared bgmac_enet_probe function. The reason for this was
|
||||
bgmac_enet_probe:
|
||||
1) Requiring early-filled struct bgmac
|
||||
2) Calling alloc_etherdev on its own in order to use netdev_priv later
|
||||
|
||||
This solution got few drawbacks:
|
||||
1) Was duplicating allocating code
|
||||
2) Required copying early-filled struct
|
||||
3) Resulted in platform/bcma code having access only to unused struct
|
||||
|
||||
Solve this situation by simply extracting some probe code into the new
|
||||
bgmac_alloc function.

Subject: [PATCH 2/3] net: bgmac: drop struct bcma_mdio we don't need anymore

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit
|
||||
|

Adding struct bcma_mdio was a workaround for bcma code not having access
|
||||
to the struct bgmac used in the core code. Now we don't duplicate this
|
||||
struct we can just use it internally in bcma code.
|
||||
|
||||
This simplifies code & allows access to all bgmac driver details from
|
||||
all places in bcma code.

Subject: [PATCH 3/3] net: bgmac: use PHY subsystem for initializing PHY
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
This adds support for using bgmac with PHYs supported by standalone PHY
|
||||
drivers. Having any PHY initialization in bgmac is hacky and shouldn't
|
||||
be extended but rather removed if anyone has hardware to test it.
