mfd: twl4030 IRQ handling update

2008-10-21T23:19:37+00:00

- Move it into a separate file; clean and streamline it - Restructure the init code for reuse during secondary dispatch - Support both levels (primary, secondary) of IRQ dispatch - Use a workqueue for irq mask/unmask and trigger configuration Code for two subchips currently share that secondary handler code. One is the power subchip; its IRQs are now handled by this core, courtesy of this patch. The other is the GPIO module, which will be supported through a later patch. There are also minor changes to the header file, mostly related to GPIO support; nothing yet in mainline cares about those. A few references to OMAP-specific symbols are disabled; when they can all be removed, the TWL4030 support ceases being OMAP-specific.

mfd: TWL4030 core driver

2008-10-19T20:54:11+00:00

This patch adds the core of the TWL4030 driver, which supports chips including the TPS65950. These chips are multi-function; see http://focus.ti.com/docs/prod/folders/print/tps65950.html Public specs are in the works. For now, the block diagram on the second page of the datasheet is fairly informative. There are some known issues with this core code. Most notably, the IRQ dispatching needs simplification (to use more of genirq), generalization (integrating support for secondary IRQ dispatch as well as primary, and removing the build dependency on OMAP), and then probably updating to leverage threaded IRQ support (expected to arrive in mainline "soon"). Once the core is in mainline, drivers for other parts of this chip can follow its lead and start swimming upstream too. Signed-off-by: David Brownell Signed-off-by: Samuel Ortiz

mfd: Add GPIO pin configuration support for WM8350

2008-10-13T20:51:55+00:00

The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions. This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so. This code was all written by Liam Girdwood and has had minor updates and rearrangements by Mark Brown. Signed-off-by: Mark Brown Acked-by: Samuel Ortiz Signed-off-by: Liam Girdwood

mfd: Add I2C control support for WM8350

2008-10-13T20:51:55+00:00

Implement the I2C control interface for the WM8350. This code was originally written by Liam Girdwood and has been updated for submission by Mark Brown. Signed-off-by: Mark Brown Acked-by: Samuel Ortiz Signed-off-by: Liam Girdwood

mfd: Core support for the WM8350 AudioPlus PMIC

2008-10-13T20:51:55+00:00

The WM8350 is an integrated audio and power management subsystem intended for use as the primary PMIC in mobile multimedia applications. The WM8350 can be controlled via either I2C or SPI - the control interface is provided by a separate module in order to allow greatest flexibility in configuring the kernel. This driver was originally written by Liam Girdwood and has since been updated to current kernel APIs and split up for submission by me. All the heavy lifting here was done by Liam.

mfd: Core support for the WM8400 AudioPlus HiFi CODEC and PMU

2008-10-13T20:51:52+00:00

The WM8400 is a highly integrated audio CODEC and power management unit optimised for use in mobile multimedia applications. This patch adds core support for the WM8400 to the MFD subsystem. Both I2C and SPI access are supported by the hardware but currently only I2C access is implemented. The code is structured to allow SPI support to be slotted in later.

[ARM] 5184/1: Split ucb1400_ts into core and touchscreen

2008-08-20T22:22:22+00:00

This patch splits ucb1400_ts into ucb1400_ts and ucb1400_core. Since this chip supports more features than only touchscreen, it was necessary to prepare it for feature addition. The previous functionality is preserved by applying this patch. [Build fixes for non-ARM by Stephen Rothwell and Takashi Iwai] Signed-off-by: Marek Vasut Signed-off-by: Russell King

mfd: driver for the TC6387XB TMIO controller.

2008-08-10T18:09:55+00:00

This patch adds support for the TC6387XB. Unlike other TMIO devices this one has only one subdevice and no interrupt mux, however using the MFD framework allows it to share the TMIO MMC driver. Signed-off-by: Ian Molton Signed-off-by: Samuel Ortiz
