AB8540 supports power path function in USB charging mode for fast power up with dead and weak battery, and it could extend the battery age. When USB charging starts, if the Vbattrue is below than SW cut off voltage, power path and pre-charge should be enabled. If Vbattrue is higher than SW cut off voltage, power path and pre-charge should be disabled. This is to make sure full current to battery charge. At the end of charge, power path should be enable again to reduce charging the battery again. Signed-off-by: Lee Jones <lee.jones@linaro.org>

No new drivers this time, but a bunch of fairly big cleanups:
- Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee Jones. In
particular, the debugfs and the sysct interfaces got extended and improved.
- Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
driver, with a much needed module id lookup code improvement.
- The regular wm5102 and arizona cleanups and fixes from Mark Brown.
- Laxman Dewangan extended the palmas APIs in order to implement the palmas
GPIO and rt drivers.
- Laxman also added DT support for the tps65090 driver.
- The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
Darren Hart.
- Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
devices to switch to the new abx500 pin-ctrl driver.
- The max8925 now has device tree and irqdomain support thanks to Qing Xu.
- The recently added rtsx driver got a few cleanups and fixes for a better
card detection code path and now also supports the RTS5227 chipset, thanks
to Wei Wang and Roger Tseng.

Today the battery recharge is determined with a voltage threshold. This voltage threshold is only valid when the battery is relaxed. In charging algorithm the voltage read is the loaded battery voltage and no compensation is done to get the relaxed voltage. When maintenance charging is not selected, this makes the recharging condition to almost immediately activate when there is a discharge present on the battery. Depending on which vendor the battery comes from this behavior can wear out the battery much faster than normal. The fuelgauge driver is responsible to monitor the actual battery capacity and is able to estimate the remaining capacity. It is better to use the remaining capacity as a limit to determine when battery should be recharged.

Currently the AB8500 battery management subsystem receives platform specific information via two different means depending on how the platform is booted. If DT is not enabled, a reference to a *_bm_data data structure containing each platform specific attribute is passed though platform_data. However, if DT is enabled, then platform_data is empty and the reference is gained though a DT specific probe function. There are two issues here 1) the same reference is being collected each time and 2) the DT way doesn't allow any provisions to select different platform specific attributes, which kind of defeats the object.

The platform specific battery management configuration data structure is currently called 'bat' short for 'battery'; however, it contains information for all components of the battery management group, rather than information pertaining to the battery itself - there are other structures for that. So, in keeping with its structure namesake 'abx500_bm_data', we rename it to 'bm' here. Using similar logic, we're also renaming 'bmdevs_of_probe' to the more device specific 'ab8500_bm_of_probe'.

This is a charging algorithm driver for abx500 variants. It is the central entity for battery driver and is responsible for charging and monitoring the battery driver. It is a hardware independant driver and also monitors other abx500 power supply devices.

The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

There are currently four different versions of the AB8500 around: AB8500, AB8505, AB9540 and AB8540. Unfortunately: - Some of the chips (AB8500, AB8505, AB9540) cannot read the AB8500_REV_REG register but return errors - Some of them have the same ID value in the hardware register AB8500_REV_REV, for example the first versions of AB8505 and AB9540 have 0xFF in this register - just like the AB8500. So we need to be able to enforce a certain version from the platform. We do this by using the id of the platform device that provides the read/write functions.

The AB3550 never passed the prototype stage. Instead it was used as a precursor to AB5500 for testing basic building blocks used in that chip, since they had large similarities. Since AB3550 will not see the light of day in product form and since the prototypes are no longer used, let's delete the driver and any references to it.

The analog baseband chip ab5500 is a multi functional chip containing regulators, charging, gpio, USB and accessory detect. It also contain various multimedia functionalities like digital encoder and audio codec. The core driver added with this patch provides register access via i2c via PRCMU. Event handling implemented as irq_chip will come in future patches since it depends on PRCMU functionality not yet implemented.

With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

No clients (in mainline kernel, I'm told that drivers exist in external trees that are planned for mainline inclusion) make use of this, nor do they make use of platform_data, so nothing really had to change here. The .data_size field is unused, so its usage gets removed. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

This patch makes the ab8500 mixed signal chip expose the same interface for register access as the ab3100, ab3550 and ab5500 chip. The ab8500_read() and ab8500_write() is removed and replaced with abx500_get_register_interruptible() and abx500_set_register_interruptible().

The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.
