[PATCH 7/8] memory: mtk-smi: Rearrange some function position alphabetically

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

 




Only adjust some code position in Soc numerical order, from mt2701,
mt2712 to mt8173.

Besides, 3 minor changes:
1) fix a coding style issue:
    CHECK: Alignment should match open parenthesis
    +               writel(reg_val,
    +                       common->smi_ao_base
2) change from readl to readl_relaxed in gen1_config_port.
3) change the type "larbid" from "int" to "unsigned int" to meet
   the requirement of of_property_read_u32.
