2008-10-16fbdev: add new TMIO framebuffer driverDmitry Baryshkov1-0/+19
Add driver for TMIO framebuffer cells as found e.g. in Toshiba TC6393XB chips.

2008-10-13mfd: Add placeholders for WM8350 client devicesMark Brown6-1/+41
In order to avoid merge problems further down the line add placeholders for several of the WM8350 client devices and register them, otherwise the patches adding the client devices will all try to update the same code. Also remove redundant checks for null regulator platform devices while we're at it.

2008-10-13regulator: Add WM8350 regulator supportMark Brown2-0/+47
The WM8350 features six DCDC convertors (four buck and two boost), four LDO voltage regulators and two constant current sinks. This driver adds support for these through the regulator API. This driver was written by Liam Girdwood with updates for submission from Mark Brown.

2008-10-13mfd: Add WM8350 interrupt supportMark Brown1-1/+20
The WM8350 has an interrupt line to the CPU which is shared by the devices on the CPU. This patch adds support for the interrupt controller within the WM8350 which identifies which identifies the interrupt cause. In common with other similar chips this is done outside the standard interrupt framework due to the need to access the interrupt controller over an interrupt-driven bus. This code was all originally written by Liam Girdwood with updates for submission by me.

2008-10-13mfd: Add initialisation callback for WM8350Mark Brown1-1/+13
Some functions of the WM8350 require board-specific initialisation on startup. Provide a callback to the WM8350 driver in platform data for platforms to use to configure the chip. Use of a callback allows platforms to control the ordering of initialisation which can be important.

2008-10-13mfd: Add GPIO pin configuration support for WM8350Mark Brown1-0/+10
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.

2008-10-13mfd: Core support for the WM8350 AudioPlus PMICMark Brown1-0/+585
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.

2008-10-13regulator: Add WM8400 regulator supportMark Brown2-0/+41
The WM8400 provides two programmable DCDC step-down (buck) convertors and four low-dropout (LDO) regulators. This driver provides support for runtime managment of these in the standard regulator API. Support for configuration of the suspend and hibernate mode behaviour of the regulators is not yet included.

2008-10-13mfd: Core support for the WM8400 AudioPlus HiFi CODEC and PMUMark Brown2-0/+2121
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.

2008-07-29mfd: add platform_data to mfd_cellMike Rapoport1-6/+7
Adding platform_data to mfd_cell allows passing of platform data directly to the platform_device created for each cell and thus reuse of existing drivers. On the other side it can be used as a hook to mfd_cell itself removing the need in mfd_get_cell method.

2008-07-20mfd: let asic3 use mem resource instead of bus_shiftPhilipp Zabel1-3/+2
The bus_shift parameter in platform_data is not needed as we can tell the driver with the IOMEM_RESOURCE whether the ASIC is located on a 16bit or 32bit memory bus. The htc-egpio driver uses a more descriptive bus_width parameter, but for drivers where the register map size fixed, we don't even need this.

2008-07-20mfd: add ASIC3_CONFIG_GPIO templatesPhilipp Zabel1-0/+29
As ASIC3 GPIO alternate function configuration is expected to be similar for several devices, it is convenient to define descriptive macros.

This is a patch for the Compaq ASIC3 multi function chip, found in many PDAs (iPAQs, HTCs...). It is a simplified version of Paul Sokolovsky's first proposal [1]. With this code, it is basically a GPIO and IRQ expander. My plan is to add more features once this patch gets reviewed and accepted.
