Subject: [PATCH net v3 0/1] net: ravb: fixes for the ravb driver

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Hi,

Series adds one fix for the ravb driver to wait for the operating
mode to be applied by hardware before proceeding.

Thank you,
Claudiu Beznea

Changes in v3:
- s/csr_opmode/csr_ops in ravb_set_opmode()
- mask opmode with CCC_OPC when retrieveing csr_ops
- in ravb_set_opmode() updated modify mask passed to ravb_modify() to
  include GAC and CSEL bits if these are part of opmode
- s/failed to switch device to config mode/failed to switch device to
  requested mode/ in ravb_set_opmode()
- s/operation/operating in the title of patch 1/1

Changes in v2:
- dropped patch 2/2 from v1 ("net: ravb: Check that GTI loading request is
  done")
- kept a single "Fixes" entry in commit description
- updated commit description for patch 1/1
- introduce ravb_set_opmode() that does all the necessities for
  setting the operating mode (set DMA.CCC and wait for CSR.OPS) and call it
  where needed; this should comply with all the HW manuals requirements as
  different manual variants specify different modes need to be checked in
  CSR.OPS when setting DMA.CCC.
