  • 02fbabd5f   regulator: stm32-vrefbuf: fix a possible overshoot when re-enabling ... Browse Code »

    There maybe an overshoot, when disabling, then re-enabling vrefbuf
    too quickly. VREFBUF is used by ADC/DAC on some boards. When re-enabling
    too quickly, an overshoot on the reference voltage make the conversions
    inaccurate for a short period of time.
    - Don't put the VREFBUF in HiZ when disabling, to force an active
    discharge.
    - Enforce a 1ms OFF/ON delay

  • f63248fac   regulator: stm32-vrefbuf: fix check on ready flag ... Browse Code »

    stm32_vrefbuf_enable() wrongly checks VRR bit: 0 stands for not ready,
    1 for ready. It currently checks the opposite.
    This makes enable routine to exit immediately without waiting for ready
    flag.
