[PATCH 01/11] MFD: DA9052/53 MFD core module v4

ashishj3 ashish.jangam at kpitcummins.com
Thu Aug 18 13:53:22 UTC 2011


The DA9052 is a highly integrated PMIC subsystem with supply domain flexibility
to support wide range of high performance application.

It provides voltage regulators, GPIO controller, Touch Screen, RTC, Battery
control and other functionality.

Changes since v4:
- Modify KConfig to support DA9052/53
- Use device registration for detemining chip id
- Lower case in device names
- Replace preprocessor directive with runtime bustype variable
- Use of subsys_initcall in spi module
- Remove MODULE_ALIAS from spi module.
Changes since v3:
- Code refactored to use REGMAP API.
- Add Battery resources.
- da9052_set_bits() and da9052_clear_bits() replaced by da9052_reg_update().
- Add support for DA9053 PMIC
Changes since v2:
- Drop da9052_irqs[] table.
- Move struct da9052_subdev_info[].
- Remove initialization of static member.
- Care for NULL pdata init().
- Check removal of subdevices on errors.
- Remove open source spi code.
- Remove '_spi' from the driver name.
- Move tbat_lookup table from header file.
- Remove irq.h 
- Remove num_gpio variable from pdata
