2017-08-22mfd: da9052: Add register details for TSISebastian Reichel2-1/+16
Add register details an channels definition for using the TSI registers in the hwmon driver. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-06-30mfd: da9053: Fix compiler warning message for uninitialised variableSteve Twiss1-1/+1
Fix compiler warning caused by an uninitialised variable inside da9052_group_write() function. Defaulting the value to zero covers the trivial case.

2015-10-30mfd: da9053: Addition of extra registers for GPIOs 8-13Steve Twiss1-0/+3
Definitions for GPIO registers 8, 9, 10, 11, 12 and 13 are added into the register header file. - DA9052_GPIO_8_9_REG 25 - DA9052_GPIO_10_11_REG 26 - DA9052_GPIO_12_13_REG 27 A modification is also made to the MFD core code to define these registers as readable and writable. The functions for da9052_reg_readable() and da9052_reg_writeable() have had their case statements altered to include these new registers.

2014-09-26mfd: da9052: Avoid setting read_flag_mask for da9052-i2c driverAxel Lin1-1/+1
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.

2014-03-19mfd: da9052: Extend support to a new chipOpensource [Anthony Olech]1-0/+1

2013-10-23mfd: da9052: Avoid multiwrite mode due to silicon errataDavid Jander1-6/+14
DA9053 (up to revision bc) can corrupt internal registers when multi-write mode is enabled and power is removed or during shutdown. Signed-off-by: David Jander <david@protonic.nl> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2013-01-27mfd: da9052/53 lockup fixAshish Jangam2-4/+65
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.

2012-11-20mfd: da9052: Introduce da9052-irq.cFabio Estevam1-0/+10
Create a da9052-irq.c file so that it can handle interrupt related functions. This is useful for allowing the da9052 drivers to use such functions when dealing with da9052 interrupts.

2012-05-13mfd: da9052: Fix genirq abuseMark Brown1-0/+1
Rather than using the pointer passed back by the regmap API (or complaining because that wasn't actually being set) the da9052 driver was having some fun and games peering through genirq and regmap internals. Fix the driver to use the API as expected. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
