  • b77eb79ac   mfd: da9061: Fix to remove BBAT_CONT register from chip model ... Browse Code »

    Remove the register DA9062AA_BBAT_CONT (0x0C5) from the DA9061 chip model
    regmap access ranges. This applies to both da9061_aa_readable_ranges[]
    and da9061_aa_writeable_ranges[].

    This change is to correct the DA9061 chip model and align it with the
    latest DA9061 Datasheet.

    This register previously appeared in the DA9061 Datasheet, Revision 3.2,
    01-Mar-2016 and has been removed from later DA9061 datasheet from Dialog,
    Revision 3.3, 04-Apr-2017.

  • 656211b1d   mfd: Add support for DA9061 ... Browse Code »

    MFD support for DA9061 is provided as part of the DA9062 device driver.

    The registers header file adds two new chip variant IDs defined in DA9061
    and DA9062 hardware. The core header file adds new software enumerations
    for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration
    for distinguishing between DA9061/62 devices in software.

    The core source code adds a new .compatible of_device_id entry. This is
    extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The
    .data entry now holds a reference to the enumerated device type.

    A new regmap_irq_chip model is added for DA9061 and this supports the new
    list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the
    new sub system components for DA9061. Support is added for a new DA9061
    regmap_config which lists the correct readable, writable and volatile
    ranges for this chip.

    The probe function uses the device tree compatible string to switch on the
    da9062_compatible_types and configure the correct mfd cells, irq chip and
    regmap config.

    Kconfig is updated to reflect support for DA9061 and DA9062 PMICs.

  • bf742a53c   mfd: da9062: Fix missing volatile registers in the core regmap_range volatile lists ... Browse Code »

    Add an updated set of registers listed in the core regmap_range volatile
    ranges defined for the DA9062.

    These new registers contain bits that cannot be considered under the full
    control of software. Under various conditions the hardware will set and/or
    automatically clear bit(s) contained in these registers.

    When using a cached version of regmap, the volatility of these registers must
    be identified otherwise the regmap operations may not ensure the registers
    are explicitly altered.

    As well as updating the list of volatile registers, this change will fix a
    corner case discovered in the DA9063 ONKEY which is used by the DA9062 core.

    In the ONKEY case, the CONTROL_B register is now listed as volatile in the
    regmap_range because it contains the bit field NONKEY_LOCK. This bit can be
    altered by hardware, in which case regmap must be notified of its ability
    to be manpiulated outside of software control.
