2011-10-24mfd: Remove mc13783 API functions and symbolsUwe Kleine-König
Now that all in-tree users are fixed to use the more general mc13xxx API the obsolete stuff can go away. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
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>
2011-01-12Change the register name definitions for mc13783Yong Shen
To make mc13783 and mc13892 share code, the register names should be changed to fit the new macro definitions in the comming patch.

2010-10-28mfd: 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 This patch introduces enough compatibility cruft to keep all users of the superseded mc13783 driver unchanged.

2010-10-28mfd: Remove deprecated mc13783 functionsUwe Kleine-König
The last user is gone since v2.6.34-rc1~40 Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-08-12mfd: New mc13783 function exposing flagsUwe Kleine-König
This is needed for the mc13783-adc driver to decide if a touch screen is connected. If so some channels are not available as generic hwmon inputs. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-05-26leds: Add mc13783 LED supportPhilippe Rétornaz
This add basic led support for Freescale MC13783 PMIC. Signed-off-by: Philippe Rétornaz <philippe.retornaz@epfl.ch> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
2010-03-06mfd/mc13783: new function reading irq mask and status registerUwe Kleine-König
The driver for the mc13783 rtc needs to know if the TODA irq is pending. Instead of tracking in the rtc driver if the irq is enabled provide that information, too.

2010-03-06mc13783: rename mc13783_{{un,}mask,ack_irq} to have a mc13783_irq prefixUwe Kleine-König
In the source file group these functions together. The mc13783 header file provides fallback implementations for the old names to prevent build failures. When all users of the old names are fixed to use the new names these can go away.

2010-03-03regulator: mc13783: consider Power Gates as digital regulators.Alberto Panizzo
GPO regulators are digital outputs that can be enabled or disabled by a dedicated bit in mc13783 POWERMISC register. In this family can be count in also Power Gates (PWGT1 and 2): enabled by a dedicated pin a Power Gate is an hardware driven supply where the output (PWGTnDRV) follow this law: Bit PWGTxSPIEN | Pin PWGTxEN | PWGTxDRV | Read Back 0 = default | | | PWGTxSPIEN ---------------+-------------+----------+------------ 1 | x | Low | 0 0 | 0 | High | 1 0 | 1 | Low | 0 As read back value of control bit reflects the PWGTxDRV state (not the control value previously written) and mc13783 POWERMISC register contain only regulator related bits, a dedicated function to manage these bits is created here with the aim of tracing the real value of PWGTxSPIEN bits and reproduce it on next writes. All POWERMISC users _must_ use the new function to not accidentally disable Power Gates supplies. v2 changes: -Better utilization of abstraction layers. -Voltage query support. GPO's and PWGTxDRV are fixed voltage regulator with voltage value of 3.1V and 5.5V respectively.

2009-12-13mfd: Near complete mc13783 rewriteUwe Kleine-König
This fixes several things while still providing the old API: - simplify and fix locking - better error handling - don't ack all irqs making it impossible to detect a reset of the rtc - use a timeout variant to wait for completion of ADC conversion - provide platform-data to regulator subdevice (This allows making struct mc13783 opaque for other drivers after the regulator driver is updated to use its platform_data.) - expose all interrupts - use threaded irq After all users in mainline are converted to the new API, some things (e.g. mc13783-private.h) can go away.
