[PATCH v6 27/33] staging: mt7621-pci: add some definitions for enabling and disabling GEN and GEN1 clocks

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

 



Instead of use hardcoded values when calling 'rt_sysc_m32' for enabling
and disabling RALINK_PCIE_CLK_GEN and RALINK_PCIE_CLK_GEN1 create
some preprocessor definitions.
