2011-03-23mfd: Push byte swap out of WM8994 bulk I/OMark Brown1-4/+6
For bulk I/O it is both convenient and more sensible to pre-swap the data rather than doing the swap as part of the I/O operation so move the byte swaps we're currently doing into the core write function into the register based functions, giving the bulk write function a straight pass through to the chip. This leaves reads inconsistent, this will be addressed as a followup patch. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-03-23mfd: Avoid copying data in WM8994 I2C writeMark Brown1-9/+13
As well as providing a trivial performance optimisation this also avoids allocating a copy of the message on the stack which is beneficial when doing large transfers. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-03-23mfd: Remove copy from WM831x I2C write functionMark Brown1-5/+13

2011-03-23regulator: MAX8997/8966 supportMyungJoo Ham4-1/+1250
This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD. In this initial release, selecting voltages or current-limit and switching on/off the regulators are supported. Controlling voltages for DVS with GPIOs is not implemented fully and requires more considerations: it controls multiple bucks (selection of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO is activated, we lose the ability to control the voltage of a single buck regulator independently; i.e., contolling a buck affects other two bucks. Therefore, using the conventional regulator framework directly might be problematic. However, in this driver, we try to choose a setting without such side effect of affecting other regulators and then try to choose a setting with the minimum side effect (the sum of voltage changes in other regulators). On the other hand, controlling all the three bucks simultenously based on the voltage set table may help build cpufreq and similar system more robust; i.e., all the three voltages are consistent every time without glitches during transition.

2011-03-23mfd: Reentrance and revamp ab8500 gpadc fetching interfaceDaniel Willerud2-46/+75
This revamps the interface so that AB8500 GPADCs are fetched by name. Probed GPADCs are added to a list and this list is searched for a matching GPADC. This makes it possible to have multiple AB8500 GPADC instances instead of it being a singleton, and rids the need to keep a GPADC pointer around in the core AB8500 MFD struct. Currently the match is made to the device name which is by default numbered from the device instance such as "ab8500-gpadc.0" but by using the .init_name field of the device a more intiutive naming for the GPADC blocks can be achieved if desired.

MAX8997/MAX8966 chip is a multi-function device with I2C bussses. The chip includes PMIC, RTC, Fuel Gauge, MUIC, Haptic, Flash control, and Battery (charging) control.

2011-03-23mfd: Add sharing for cs5535 acpi/pms cellsAndres Salomon2-22/+57
This enables sharing of cs5535-mfd cells via the new mfd_shared_* API. Hooks for enable/disble of resources are added, with refcounting of resources being automatically handled so that cs5535_mfd_res_enable/disable are only called when necessary. Clients of cs5535-mfd (in this case, olpc-xo1.c) are also modified to use the mfd_shared API. The platform drivers are also renamed to olpc-xo1-{pms,acpi}, and resource enabling/disabling is replaced with mfd_shared API calls.

2011-03-23mfd: add platform_device sharing support for mfdAndres Salomon2-0/+70
This adds functions to enable platform_device sharing for mfd clients. Each platform driver (mfd client) that wants to share an mfd_cell's platform_device uses the mfd_shared_platform_driver_{un,}register() functions instead of platform_driver_{un,}register(). Along with registering the platform driver, these also register a new platform device with the same characteristics as the original cell, but a different name. Given an mfd_cell with the name "foo", drivers that want to share access to its resources can call mfd_shared_platform_driver_register with platform drivers named (for example) "bar" and "baz". This will register two platform devices and drivers named "bar" and "baz" that share the same cell as the platform device "foo". The drivers can then call "foo" cell's enable hooks (or mfd_shared_cell_enable) to enable resources, and obtain platform resources as they normally would. This deals with platform handling only; mfd driver-specific details, hardware handling, refcounting, etc are all dealt with separately.

2011-03-23mfd: Add refcounting support to mfd_cellsAndres Salomon2-5/+73

Mfd drivers can provide enable/disable hooks to actually tweak the hardware, and clients can call mfd_shared_cell_{en,dis}able without having to worry about whether or not another client happens to have enabled or disabled the cell/hardware. Note that this is purely optional; drivers can continue to use the mfd_cell's enable/disable hooks for their own purposes, if desired.
