[PATCH V4 0/5] mmc: mmci: add get_datactrl_cfg callback

[Ludovic Barre <ludovic.Barre@st.com>]

From: Ludovic Barre <ludovic.barre@st.com>

This patch series adds get_datactrl_cfg callback in mmci_host_ops
to allow to get datactrl configuration specific at variant.

change V4:
-keep mmci and ux500v2 variant init in the c file.

change V3:
-keep the common functions in mmci_start_data. define
function used by some variants like an helper
(example mmci_dctrl_blks used by mmci and sdmmc).
-To be consistent rename callback for ux500v2 

change V2:
-This V2 has been rebased on
"mmc: mmci: Cleanup some variant related code" series
-add helpers functions to define default datactrl value,
each variant could use these helpers to define datactrl
and adds their specific bits.
-use static in qcom and stm32
-regroup mmci_(ux500v2)variant_init in header file
to avoid checkpatch warning:
"WARNING: externs should be avoided in .c files"
-remove unused variant properties:
 "datactrl_dpsm_enable"
 "blksz_datactrl16"
 "blksz_datactrl4"

Ludovic Barre (5):
  mmc: mmci: add get_datactrl_cfg callback and helper functions
  mmc: mmci: define get_dctrl_cfg for legacy variant
  mmc: mmci: qcom: define get_dctrl_cfg
  mmc: mmci: stm32: define get_dctrl_cfg
  mmc: mmci: replace blksz_datactrlXX by get_datactrl_cfg callback
