[PATCH v4 0/2] mmc: mediatek: add support for 64-steps tuning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Change in v4:
- for SD/SDIO, tune 64 steps by default
- reduce some breaks to improve code readability

Change in v3:
- use BIT_ULL() instead of BIT() to avoid potential left shift operations
  that could cause exceed boundary problem on 32-bit platforms

Change in v2:
- move the change made to document to the front
- change mediatek,tune-step dts property type to enum for better scalability

Axe Yang (2):
  dt-bindings: mmc: mtk-sd: add tuning steps related property
  mmc: mediatek: extend number of tuning steps
