mfd: Add WM8326 support

2011-01-14T11:37:39Z

The WM8326 is a high performance variant of the WM832x series with no software visible differences. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Factor out WM831x I2C I/O from the core driver

2010-10-28T22:30:24Z

In preparation for the addition of SPI support for the WM831x move the I2C specific code into a separate file with a separate Kconfig option so the I2C support can be excluded from the build. Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new symbol. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Ensure WM831x charger interrupts are acknowledged when suspending

2010-05-27T23:37:39Z

The charger interrupts on the WM831x are unconditionally a wake source for the system. If the power driver is not able to monitor them (for example, due to the IRQ line not having been wired up on the system) then any charger interrupt will prevent the system suspending for any meaningful amount of time since nothing will ack them. Avoid this issue by manually acknowledging these interrupts when we suspend the WM831x core device if they are masked. If software is actually using the interrupts then they will be unmasked and this change will have no effect. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Use completion interrupt for WM831x AUXADC

2010-03-07T21:17:34Z

Use the completion interrupt generated by the device rather than polling for conversions to complete. As a backup we still check the status of the AUXADC if we don't get a completion, mostly for systems that don't have the WM831x interrupt infrastructure hooked up. Also reduce the timeout for completion of conversions to 5ms from the previous 10ms, the lower timeout should be sufficient. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Add WM831x revision B support

2010-03-07T21:17:29Z

Revision B of the WM831x devices changes the sense of the tristate bit for GPIO configuration, inverting it to become an enable instead. Take account of this in the gpiolib driver. A current sink regulation status bit has also been added in revision B, add a flag indicating if it's present but don't use it yet. This revision also adds an interrupt on key up for the ON pin event which the existing code is able to take advantage of. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Move WM831x to generic IRQ

2009-12-13T18:21:41Z

Replace the wm831x-local IRQ infrastructure with genirq, allowing access to the diagnostic infrastructure of genirq and allowing us to implement interrupt support for the GPIOs. The switchover is done within the wm831x specific IRQ API, further patches will convert the individual drivers to use genirq directly. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: Add support for WM8320 PMICs

2009-12-13T18:20:44Z

The WM8320 is an integrated power management subsystem providing voltage regulators, RTC, watchdog and other functionality. The WM8320 is derived from the WM831x and therefore shares most of the driver code with the WM831x. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

gpiolib: Make WM831x GPIO count dynamic

2009-12-13T18:20:43Z

This supports future devices with fewer GPIOs. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

input: Add support for the WM831x ON pin

2009-09-17T07:47:02Z

The WM831x series of PMICs support control of initial power on through the ON pin on the device with soft control of the pin at other times. Represent this to userspace as KEY_POWER. Signed-off-by: Mark Brown Acked-by: Dmitry Torokhov Signed-off-by: Samuel Ortiz
