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.

mfd: Drop owner assignment from i2c_drivers

2015-08-11T14:08:48+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

mfd: da9052-i2c: Remove duplicate test for I2C_FUNC_SMBUS_BYTE_DATA functionality

2014-09-26T07:15:41+00:00

Since commit b42261078a91 ("regmap: i2c: fallback to SMBus if the adapter
does not support standard I2C"), regmap-i2c will check the
I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config
setting if the adapter does not support standard I2C.

So remove the I2C_FUNC_SMBUS_BYTE_DATA functionality check in the driver code.

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: Avoid multiwrite mode due to silicon errata

2013-10-23T15:20:32+00:00

DA9053 (up to revision bc) can corrupt internal registers when multi-write
mode is enabled and power is removed or during shutdown.

mfd: da9052-i2c: Staticize da9052_i2c_fix()

2013-02-13T23:26:41+00:00

da9052_i2c_fix() is only used locally, so let it be static.

Fix the following sparse warning:

drivers/mfd/da9052-i2c.c:63:5: warning: symbol 'da9052_i2c_fix' was not declared. Should it be static?

mfd: da9052/53 lockup fix

2013-01-27T00:35:32+00:00

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.

The failure case is where this unwanted write transfers incorrect data to
a critical register.

This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.
