[PATCH 0/4] net: fman: Various cleanups

[PATCH 0/4] net: fman: Various cleanups

[Sean Anderson]

This series performs a variety of cleanups for dpaa/fman, with the aim
of reducing unused flexibility. I've tested this on layerscape, but I
don't have any PPC platforms to test with (nor do I have access to the
dtsec errata).


Sean Anderson (4):
  net: fman: Convert to SPDX identifiers
  net: fman: Don't pass comm_mode to enable/disable
  net: fman: Store en/disable in mac_device instead of mac_priv_s
  net: fman: dtsec: Always gracefully stop/start

SPDX license identifiers instead.

[PATCH 2/4] net: fman: Don't pass comm_mode to enable/disable

[Sean Anderson]

mac_priv_s->enable() and ->disable() are always called with
a comm_mode of COMM_MODE_RX_AND_TX. Remove this parameter, and refactor
the macs appropriately.

[PATCH 3/4] net: fman: Store en/disable in mac_device instead of mac_priv_s

[Sean Anderson]

All macs use the same start/stop functions. The actual mac-specific code
lives in enable/disable. Move these functions to an appropriate struct,
and inline the phy enable/disable calls to the caller of start/stop.

[PATCH 4/4] net: fman: dtsec: Always gracefully stop/start

[Sean Anderson]

There are two ways that GRS can be set: graceful_stop and dtsec_isr. It
is cleared by graceful_start. If it is already set before calling
graceful_stop, then that means that dtsec_isr set it. In that case, we
will not set GRS nor will we clear it (which seems like a bug?). For GTS
the logic is similar, except that there is no one else messing with this
bit (so we will always set and clear it). Simplify the logic by always
setting/clearing GRS/GTS. This is less racy that the previous behavior,
and ensures that we always end up clearing the bits. This can of course
clear GRS while dtsec_isr is waiting, but because we have already done
our own waiting it should be fine.

This is the last user of enum comm_mode, so remove it.

# Form letter - net-next is closed

We have already sent the networking pull request for 5.19
and therefore net-next is closed for new drivers, features,
code refactoring and optimizations. We are currently accepting
bug fixes only.

Please repost when net-next reopens after 5.19-rc1 is cut.

RFC patches sent for review only are obviously welcome at any time.

Hi

I ran sanity checks on two PPC platforms (T2080, P5020).
