| * | power_supply: Add driver for the PMU on WM831x PMICsMark Brown2009-09-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WM831x PMICs provide power path management from three sources: a wall supply, USB and a battery with integrated charger. They also provide an additional backup supply with integrated for maintaining always on functionality such as the RTC and monitoring of power switches. After some initial configuration at startup the device operates autonomously, the driver simply provides reporting of the current state.

| * | ds2760_battery: implement set_charged() featureDaniel Mack2009-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ds2760's internal current meter is not reliable enough as it has an inacurracy of around ~15%. Without any correction for that error, the current accumulator is couting up all the time, even though the battery is already fully charged and hence destroys the static information. The longer it is connected, the worse is the aberration. Fortunately, this can be corrected by the DS2760_CURRENT_OFFSET_BIAS register. Using the external power_supply_set_battery_charged() function, this register is now gauging the measurement. A delayed work is used to debounce flaky GPIO signals and to let the current value settle. Also see Maxim's application note AN4188.

It also includes functions to get a power_supply device from the class of registered devices by name reference. These can be used to find a specific battery to call power_supply_set_battery_charged() on. Some battery drivers might need this information to calibrate themselves.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When connecting a ds2760 to a partly loaded battery the first time, there must be a way to bootstrap the current_accum value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In systems where the battery monitor is not part of the battery pack and is hence not bootstrapped with sane values, the full_active_uAh is likely to be zero. Handle that case by defaulting to the rated_capacity information which can be passed to the driver using the new module parameter.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For systems where the ds2760 is soldered directly on the PCB, the 'rated capacity' register is not set to anything useful. In order to allow users to bootstrap this value, introduce a new module parameter 'rated_capacity' and use it to write the internal EEPROM in case the value differes from what's been given.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds prefetch support to access nand flash in mpu mode. This patch also adds 8-bit nand support (omap_read/write_buf8). Prefetch can be used for both 8- and 16-bit devices.

This approach is a lot less intrusive as adding an of-wrapper around plat-ram.c. As most extensions of plat-ram.c (e.g. custom map-functions) can't be mapped to the device tree anyhow, extending physmap_of seems to be the cleanest approach. Tested with a phyCORE-MPC5121e.

We are using a 1.8V NAND flash which datasheet (unfortunately only available under NDA) says : Page size: x8: 2,112 bytes (2,048 + 64 bytes). Without this patch, all sectors are marked as bad eraseblock.

So convert all of the code to pass back the correct return value and log error messages properly (and using the new pr_fmt() helper). If everything does go smoothly, rather than exit silently, dump a helpful info message like pretty much every other MTD driver does.

The latter form is obviously much better for performance, so let's use it when possible.
