mfd: Set tps6586x bits if new value is different from the old one

2011-12-20T17:50:56Z

It does not make sense to write new value only when all the bit_mask bits are zero. We need to write new value if the bit mask fields of new value is not equal to old value. Signed-off-by: Axel Lin Signed-off-by: Samuel Ortiz

mfd: Fix tps6586x GPIO value setting

2011-05-26T17:45:31Z

In the current code, every time we set a TPS6586x GPIO pin, the tps6586x_gpio_set function is resetting all other GPIO pins. We need to update the right GPIOxOUT bit of the GPIOSET2 register instead of overriding the full value. Tested by setting sequentially GPIO2 and GPIO3 and verifying the pins voltage.

mfd: Invert tps6586x GPIO and subdevices initialization

2011-03-23T09:41:45Z

When using a fixed voltage regulator triggered by a TPS6586x GPIO, this allows to declare and initialize it conveniently from the "subdev" list. Signed-off-by: Vincent Palatin Signed-off-by: Samuel Ortiz

mfd: Avoid tps6586x burst writes

2011-03-02T09:57:50Z

tps6586 does not support burst writes. i2c writes have to be 1 byte at a time. Cc: stable@kernel.org Signed-off-by: Varun Wadekar Signed-off-by: Samuel Ortiz

mfd: Convert tps6586x driver to new irq_ API

2011-01-14T11:38:08Z

The genirq core is being updated to supply struct irq_data to irq_chip operations rather than an irq number. Update the tps6586x driver to the new APIs. Signed-off-by: Mark Brown Acked-by: Mike Rapoport Signed-off-by: Samuel Ortiz

mfd: Remove tps6586x device ID check

... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.

mfd: Add TPS658621C device ID

The interface for this device should be identical to that of the TPS658521A. Signed-off-by: Andrew Chew Acked-by: Mike Rapoport Signed-off-by: Samuel Ortiz

mfd: Add basic tps6586x interrupt support
