| | | | | | | | | | | | | | | | | | | | | This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

| | | | | | | | | | | | | | | | This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.

* mfd: Print warning for twl4030 out-of-order script loadingAmit Kucheria2009-09-171-0/+6
| | | | | | | | | | | | | | | | | When the sleep script is loaded before the wakeup script, there is a chance that the system might go to sleep before the wakeup script loading is completed. This will lead to a system that does not wakeup and has been observed to cause non-booting boards. Various options were considered to solve this problem, including modification of the core twl4030 power code to be smart enough to reorder the loading of the scripts. But it felt too over-engineered. Hence this patch just warns the DPS script developer so that they may be reordered in the board-code itself.

| | | | | | | | | | | | | The TWL4030/5030 family of multifunction devices allows board-specific control of the the various regulators, clock and reset lines through 'scripts' that are loaded into its memory. This allows for Dynamic Power Switching (DPS). Implement board-independent core support for DPS that is then used by board-specific code to load custom DPS scripts.

* mfd: AB3100 OTP readoutLinus Walleij2009-09-173-0/+278
| | | | | | | | | | | | This adds the ability to read out OTP (One-Time Programmable) registers in the AB3100 MFD ASIC. It's a simple sysfs file you can cat to prompt. The OTP registers of the AB3100 are used to store various device-unique information such as customer ID, product flags and the 3GPP standard IMEI (International Mobile Equipment Indentity) number.

* mfd: AB3100 accessor function cleanupsLinus Walleij2009-09-171-19/+24
| | | | | | | | | | | | | This adds the _interruptible suffix to the AB3100 accessor functions on par with mutex_lock_interruptible() that's used for blocking simultaneous calls to the AB3100 acessor functions. Since these accesses are slow on a 100kHz I2C bus and may line up waiting for the mutex, we need to handle interruption by system shutdown or kill signals and may just as well denote that in the function names.

* mfd: Export ISEL values from WM831x coreMark Brown2009-09-171-0/+64
| | | | | | | | | | | The current settings which can be used with the WM831x current sinks can't easily be mapped between register values and currents at run time without a lookup table since the values scale logarithmically to match the way the human eye interprets brightness. This lookup table is inclided in the core since several drivers need to use it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: Add basic WM831x OTP supportMark Brown2009-09-172-0/+87
| | | | | | | | | | | | | | The WM831x series of devices use OTP (One Time Programmable, a type of PROM) to store system configuration. At run time this data is visible via registers. Currently the only explicitly supported feature is that the unique ID provided by every WM831x device is exported to user space via sysfs. Other configuration data may be read by system-specific code in the pre_init() and post_init() platform data operations.

* mfd: Conditionally add WM831x backlight subdeviceMark Brown2009-09-171-0/+15
| | | | | | | | | | | The WM831x backlight driver requires at least the specification of the current sink to use and a maximum current to allow them to function and will actively interfere with other users of the regulators it uses if misconfigured so only register the subdevice for it if this platform data has been supplied.

* mfd: Add WM831x AUXADC supportMark Brown2009-09-171-0/+101
| | | | | | | | | | | | | | | | | The WM831x contains an auxiliary ADC with a number of switchable inputs which is used to monitor some of the voltages and temperatures in the system and has some external inputs which can be used for machine specific purposes. Provide an API allowing drivers to read values from the ADC. An internal reference voltage is provided to allow callibration of the ADC. This is used to calibrate the device at startup. The hardware also supports continuous readings and digital comparators. These are not yet supported by the driver.

* mfd: Add WM831x interrupt supportMark Brown2009-09-172-2/+569
| | | | | | | | | | | | | | | | The WM831x includes an interrupt controller managing interrupts for the various functions on the chip. This patch adds support for the core interrupt block on the device. Ideally this would be supported by genirq, particularly for the GPIOs, but currently genirq is unable to cope with controllers on interrupt driven buses so we cut'n'paste the generic interface. Once genirq is able to cope chips like this it should be a case of filing the prefixes off the code and redoing wm831x-irq.c to move over.

* mfd: Allow multiple MFD cells with the same nameMark Brown2009-09-171-1/+1
| | | | | | | | | | | | | | | Provide basic support for MFDs having multiple cells of a given type with different IDs by adding an id to the mfd_cell structure and then adding that to the id passed in to mfd_add_devices(). As it stands this approach requires that MFDs using this feature deal with ensuring that there aren't any ID collisions resulting from multiple MFDs of the same type being instantiated. This needs to happen with the existing code too, but with this approach there is a knock on effect on the IDs for non-duplicated devices.

| | | | | | | | | | | | | | | | | | | | This patch corrects the support for MMCSD card detection and read only feature for SoC DM355. EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that Bit 2 and 4 should be checked for card detection. However on the EVM, bits 1 and 3 gives this status, for MMC/SD instance 0 and 1 respectively. The pdf also suggests that Bit 1 and 3 should be checked for write protection. However on the EVM bits 2 and 4 gives this status.

* mfd: revise locking for pcf50633 ADCPaul Fertser2009-09-171-16/+16
| | | | | | | | | | | | | | Current implementation is prone to races, this patch attempts to remove all but one (in pcf50633_adc_sync_read). The idea is that we need to guard the queue access only on inserting and removing items. If we insert and there're no more items in the queue it means that the last irq already happened and we need to trigger ADC manually. If not, then the next conversion will be triggered by the irq handler upon completion of the previous.

* mfd: use a dedicated workqueue for pcf50633 irq processingPaul Fertser2009-09-171-1/+4
| | | | | | | | | | | | | | Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

* mfd: twl4030 irq fixesRussell King2009-08-041-31/+24
| | | | | | | | | | | | | | | | | | | The TWL4030 IRQ handler has a bug which leads to spinlock lock-up. It is calling the 'unmask' function in a process context. :The mask/unmask/ack functions are only designed to be called from the IRQ handler code, or the proper API interfaces found in linux/interrupt.h. Also there is no need to have IRQ chaining mechanism. The right way to handle this is to claim the parent interrupt as a standard interrupt and arrange for handle_twl4030_pih to take care of the rest of the devices.
