mfd: da9052: Simplify function return logic

2015-10-30T17:19:46+00:00

The invoked functions already return zero on success or a negative
errno code so there is no need to open code the logic in the caller.

spi: Drop owner assignment from spi_drivers

2015-10-28T01:30:17+00:00

An spi_driver does not need to set an owner, it will be populated by the
driver core.

mfd: da9052: Fix register access via SPI

2015-03-12T09:06:40+00:00

The range of registers used by this driver exceeds that available
via SPI with no paging (127), so we have to override the values
from the default config which is set-up for I2C access.
Also change SPI settings to match device's recommended OTP values.

mfd: da9052: Avoid setting read_flag_mask for da9052-i2c driver

2014-09-26T07:15:54+00:00

Current code init regmap with &da9052_regmap_config for both da9052-spi and
da9052-i2c drivers. da9052-spi sets the read_flag_mask.
The same setting may be applied for da9052-i2c if da9052-spi driver is loaded
first because they actually use the same regmap_config setting.
Fix this issue by using a local variable for regmap_config in da9052-spi driver,
so the settings in spi driver won't impact the settings in i2c driver.
Also makes da9052_regmap_config const to avoid similar issue.

mfd: da9052: Add new DA9053 BC chip variant

2014-03-19T08:58:25+00:00

Add support for a new BC variant of the DA9053 PMIC.

There is one difference between it and the AA, BA and BB.

This patch also corrects a typing mistake in one of the BA
name strings that was incorrectly typed as "ab".

mfd: da9052: Use spi_get_drvdata() and spi_set_drvdata()

2013-04-09T10:18:16+00:00

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.
