[PATCH 0/7] slimbus: fixes and some helpers

[Srinivas Kandagatla]

Hi Greg,

Here is set of patches for slimbus, there are 5 fixes and
two helper functions.
Most of these issues were found while testing QCOM NGD SLIMBus
controller with WCD9335 codec.

thanks,
Srini

Srinivas Kandagatla (7):
  slimbus: core: add of_slim_device_get() helper
  slimbus: core: rearrange slim_eaddr structure
  slimbus: core: add need_tid flag to slim_msg_txn
  slimbus: messaging: pass correct wbuf
  slimbus: messaging: remove multiple calls to pm_runtime_mark_last_busy
  slimbus: messaging: add slim_prepare_txn() helper function
  slimbus: messaging: initialize completion correctly

[PATCH 1/7] slimbus: core: add of_slim_device_get() helper

[Srinivas Kandagatla]

On SLIMBus controllers like Qcom NGD(non ported device), controller
can request logical address once the remote side is powered, having a
helper function like this to explicitly enumerate the bus is helpful.
Also codec drivers which are taking to interface device would need
such a helper too.

[PATCH 2/7] slimbus: core: rearrange slim_eaddr structure

[Srinivas Kandagatla]

Rearrange struct slim_eaddr so that the structure is packed correctly
to be able to send in SLIMBus messages.

[PATCH 3/7] slimbus: core: add need_tid flag to slim_msg_txn

[Srinivas Kandagatla]

Add need_tid flag to txn, this flag can be set before start of transcation.
Having this flag would avoid calling slim_tid_txn() multiple times on the
same txn. Also it is handy for controller drivers too.

[PATCH 5/7] slimbus: messaging: remove multiple calls to pm_runtime_mark_last_busy

[Srinivas Kandagatla]

There seems to be a multiple calls to pm_runtime_mark_last_busy(),
which looks like a typo.
Fix this by properly adding pm_runtime_put_autosuspend to put controller
in auto suspend state.
