Also, it stores the phase settings into the dw_mmc controller, so the code has to be adapted to implement that. Changes since v1: - Renamed use-v2-tuning to v2-tuning - Rewrite v2-tuning description as the hardware feature Detlev Casanova (1): dt-bindings: mmc: Add support for rk3576 dw-mshc Shawn Lin (2): mmc: dw_mmc-rockchip: Add v2 tuning support mmc: dw_mmc-rockchip: Add internal phase support .../bindings/mmc/rockchip-dw-mshc.yaml | 7 + drivers/mmc/host/dw_mmc-rockchip.c | 223 +++++++++++++++++- 2 files changed, 221 insertions(+), 9 deletions(-)
