    Subject[PATCH 5.10 711/717] regulator: axp20x: Fix DLDO2 voltage control register mask for AXP22x
    Date
    From: DingHua Ma <dinghua.ma.sz@gmail.com>

    commit 291de1d102fafef0798cdad9666cd4f8da7da7cc upstream.

    When I use the axp20x chip to power my SDIO device on the 5.4 kernel,
    the output voltage of DLDO2 is wrong. After comparing the register
    manual and source code of the chip, I found that the mask bit of the
    driver register of the port was wrong. I fixed this error by modifying
    the mask register of the source code. This error seems to be a copy
    error of the macro when writing the code. Now the voltage output of
    the DLDO2 port of axp20x is correct. My development environment is
    Allwinner A40I of arm architecture, and the kernel version is 5.4.
