  • 962f170d9   regulator: lm363x: Fix n_voltages setting for lm36274 ... Browse Code »

    According to the datasheet http://www.ti.com/lit/ds/symlink/lm36274.pdf:
    Table 23. VPOS Bias Register Field Descriptions VPOS[5:0]:
    VPOS voltage (50-mV steps): VPOS = 4 V + (Code × 50 mV), 6.5 V max
    000000 = 4 V
    000001 = 4.05 V
    :
    011110 = 5.5 V (Default)
    :
    110010 = 6.5 V
    110011 to 111111 map to 6.5 V

    So the LM36274_LDO_VSEL_MAX should be 0b110010 (0x32).
    The valid selectors are 0 ... LM36274_LDO_VSEL_MAX, n_voltages should be
    LM36274_LDO_VSEL_MAX + 1. Similarly, the n_voltages should be
    LM36274_BOOST_VSEL_MAX + 1 for LM36274_BOOST.

  • 1e2cc8c5e   regulator: lm363x: Fix off-by-one n_voltages for lm3632 ldo_vpos/ldo_vneg ... Browse Code »

    According to the datasheet https://www.ti.com/lit/ds/symlink/lm3632a.pdf
    Table 20. VPOS Bias Register Field Descriptions VPOS[5:0]
    Sets the Positive Display Bias (LDO) Voltage (50 mV per step)
    000000: 4 V
    000001: 4.05 V
    000010: 4.1 V
    ....................
    011101: 5.45 V
    011110: 5.5 V (Default)
    011111: 5.55 V
    ....................
    100111: 5.95 V
    101000: 6 V
    Note: Codes 101001 to 111111 map to 6 V

    The LM3632_LDO_VSEL_MAX should be 0b101000 (0x28), so the maximum voltage
    can match the datasheet.

    Adding regulator support for the LM36274 backlight driver.
    This device can leverage this existing code as the functionality
    and registers are common enough between the LM36274 and the LM363x
    series of devices.

    Use the gpiod_get() rather than the devm_* version so that the
    regulator core can handle the lifecycle of these descriptors.

  • 63239e4bf   regulator: Fetch enable gpiods nonexclusive ... Browse Code »

    Since the core regulator code is treating GPIO descriptors as
    nonexclusive, i.e. it assumes that the enable GPIO line may be
    shared with several regulators, let's add the flag introduced
    for fixing this problem on fixed regulators to all drivers
    fetching GPIO descriptors to avoid possible regressions.

  • 3a8d1a73a   regulator: add LM363X driver ... Browse Code »

    LM363X regulator driver supports LM3631 and LM3632.
    LM3631 has 5 regulators. LM3632 provides 3 regulators.
    One boost output and LDOs are used for the display module.
    Boost voltage is configurable but always on.
    Supported operations for LDOs are enabled/disabled and voltage change.

    Two LDOs of LM3632 can be controlled by external pins.
    Those are configured through the DT properties.
