2012-05-01mfd: Move the mc13xxx-core spi specific code into a separate moduleMarc Reilly
All spi specific code is moved into a new module. The mc13xxx struct moves to a new local include file by necessity. A new config choice selects the SPI bus type support and by default is value of SPI_MASTER to remain compatible with existing configs.

2012-05-01mfd: Use regmap for the mc13xxx-core register accessMarc Reilly
This change converts the mc13xxx core to use regmap rather than direct spi r/w. The spidev member of mc13xxx struct becomes redundant and is removed. Extra debugging aids are added to mc13xxx_reg_rmw. Mutex init is moved to before regmap init.

2012-05-01mfd: Prepare for separating spi and i2c mc13xxx-core backendsMarc Reilly
This patch abstracts the bus specific operations from the driver core. Generic init and cleanup is consolidated into mc13xxx_common_*. spi specific functions are renamed to reflect such. (The irq member of the mc13xxx struct is no longer redundant, it's used to store the irq for cleanup time).

2012-03-06mfd: Add pdata to set mc13783-ts conversion delayMichael Thalmeier
MC13783 can be programmed to wait some clock cycles between the touchscreen polarization and the resistance conversion. This is needed to adjust for touchscreens with high capacitance between plates.

2012-01-09mfd: Fixed unconditional reset of the mc13xxx ADC reading enable bitsRobin van der Gracht
When the ADC is being prepared for a single or multiple channel reading, the adc0 register is reconfigured without taking the lithium cell, charge current and battery current reading enable bits into account. Which results in clearing the bits. Signed-off-by: Robin van der Gracht <robin@protonic.nl> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-01-09mfd: Remove redundant spi driver bus initializationLars-Peter Clausen
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register(), so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

A led subdevice is registered now iff the corresponding platform data is available. Without platform data the device isn't usable so this is a sound check.

2011-10-24mfd: Provide a generic version of mc13xxx adc_do_conversionUwe Kleine-König
This is needed to convert the touch driver away from using struct mc13783. Note this patch drops MC13783_ADC0_ADREFMODE. This is unused and doesn't exist on mc13892. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-05-26mfd: Use mfd cell platform_data for mc13xxx cells platform bitsSamuel Ortiz
With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

2011-03-23mfd: Rename platform_data field of mfd_cell to mfd_dataAndres Salomon
Rename the platform_data variable to imply a distinction between common platform_data driver usage (typically accessed via pdev->dev.platform_data) and the way MFD passes data down to clients (using a wrapper named mfd_get_data). All clients have already been changed to use the wrapper function, so this can be a quick single-commit change that only touches things in drivers/mfd.

2011-03-23mfd: mfd_cell is now implicitly available to mc13xxx driversAndres Salomon
The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2010-10-29mfd: Add mc13892 support to mc13xxxUwe Kleine-König
mc13892 is the companion PMIC for Freescale's i.MX51. It's similar enough to mc13782 to support it in a single driver. This patch introduces enough compatibility cruft to keep all users of the superseded mc13783 driver unchanged.
