* mfd: Add atmel-hlcdc driverBoris Brezillon2014-11-251-0/+1
| | | | | | | | | | | | | | | | | | The HLCDC IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) exposes 2 subdevices: - a display controller (controlled by a DRM driver) - a PWM chip The MFD device provides a regmap and several clocks (those connected to this hardware block) to its subdevices. This way concurrent accesses to the iomem range are handled by the regmap framework, and each subdevice can safely access HLCDC registers.

* mfd: Add support for Diolan DLN-2 devicesOctavian Purdila2014-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO Master Adapter DLN-2. Details about the device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Information about the USB protocol can be found in the Programmer's Reference Manual [1], see section 1.7. Because the hardware has a single transmit endpoint and a single receive endpoint the communication between the various DLN2 drivers and the hardware will be muxed/demuxed by this driver. Each DLN2 module will be identified by the handle field within the DLN2 message header. If a DLN2 module issues multiple commands in parallel they will be identified by the echo counter field in the message header. The DLN2 modules can use the dln2_transfer() function to issue a command and wait for its response. They can also register a callback that is going to be called when a specific event id is generated by the device (e.g. GPIO interrupts). The device uses handle 0 for sending events.

* | mfd: vexpress: Convert custom func API to regmapPawel Moll2014-05-151-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Components of the Versatile Express platform (configuration microcontrollers on motherboard and daughterboards in particular) talk to each other over a custom configuration bus. They provide miscellaneous functions (from clock generator control to energy sensors) which are represented as platform devices (and Device Tree nodes). The transactions on the bus can be generated by different "bridges" in the system, some of which are universal for the whole platform (for the price of high transfer latencies), others restricted to a subsystem (but much faster). Until now drivers for such functions were using custom "func" API, which is being replaced in this patch by regmap calls. This required: * a rework (and move to drivers/bus directory, as suggested by Samuel and Arnd) of the config bus core, which is much simpler now and uses device model infrastructure (class) to keep track of the bridges; non-DT case (soon to be retired anyway) is simply covered by a special device registration function * the new config-bus driver also takes over device population, so there is no need for special matching table for of_platform_populate nor "simple-bus" hack in the arm64 model dtsi file (relevant bindings documentation has been updated); this allows all the vexpress devices fit into normal device model, making it possible to remove plenty of early inits and other hacks in the near future * adaptation of the syscfg bridge implementation in the sysreg driver, again making it much simpler; there is a special case of the "energy" function spanning two registers, where they should be both defined in the tree now, but backward compatibility is maintained in the code * modification of the relevant drivers: * hwmon - just a straight-forward API change * power/reset driver - API change * regulator - API change plus error handling simplification * osc clock driver - this one required larger rework in order to turn in into a standard platform driver Signed-off-by: Pawel Moll <pawel.moll@arm.com> Acked-by: Mark Brown <broonie@linaro.org> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Mike Turquette <mturquette@linaro.org>

The only reason the file was split out was because we planned to support other pm8xxx chips with different pm8xxx-core.c files. Now that we have DT on ARM this isn't necessary because we should be able to support all the ssbi based PM8xxx chips in one driver and one file with no data bloat. Let's move this code into the only driver that uses it right now (pm8921) so that it's always compiled when needed. In the future we can rename pm8921-core.c to something more generic.

| | | | | | | | | | | | | | | | This patch adds all necessary header files and Kbuild plumbing for the core driver for Silicon Laboratories Si476x series of AM/FM tuner chips. The driver as a whole is implemented as an MFD device and this patch adds a core portion of it that provides all the necessary functionality to the two other drivers that represent radio and audio codec subsystems of the chip.

* mfd: rtsx: Support RTS5249Wei WANG2013-04-191-1/+1
| | | | | | | | | | | | RTS5249 supports SD UHS-II interface. In order to support SD UHS-II，the definitions of some internal registers of RTS5249 have to be modified and are different from its predecessors. So we need this patch to ensure RTS5249 can work, even SD/MMC stack doesn't support UHS-II interface.

| | | | | | | | | | | | | | | | | | | This is the base EC implementation, which provides a high level interface to the EC for use by the rest of the kernel. The actual communcations is dealt with by a separate protocol driver which registers itself with this interface. Interrupts are passed on through a notifier. A simple message structure is used to pass messages to the protocol driver.

We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...
