"Highlights:
- class based instantiation finally dropped for most embedded drivers
bringing boot up performance gains
- removed two drivers (one outdated, one a duplicate)
- ACPI has now operation region support (thanks to Lan Tianyu)
- the i2c-stub driver got overhauled and gained new features to
become more useful when writing i2c client drivers (thanks to
Guenter Roeck and Jean Delvare)

The existing implementation which encodes the configuration as a binary blob in platform data is unsatisfactory since it requires a kernel recompile for the configuration to be changed, and it doesn't deal well with firmware changes that move values around on the chip. Atmel define an ASCII format for the configuration which can be exported from their tools. This patch implements a parser for that format which loads the configuration via the firmware loader and sends it to the MXT chip.

It turned out that the s6000 simply has a designware IP core and should use the designated driver for it which is way more maintained and feature complete. There are currently no users in tree, and not even a toolchain for s6000 seems to be available. So, simply remove this duplicate. If someone needs assistance in converting to the designware driver, the i2c list will be there to help. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

The twl4030 PMIC needs to be configured properly for things like warm reset and deeper idle states so the PMIC manages the regulators properly based on the hardware triggers from the SoC. Earlier we have configured twl4030 using platform data, but we want to do it for device tree based booting also. In some cases configuring twl4030 is needed for things to work. For example, when rebooting an OMAP3530 at 125 MHz, it hangs. With this patch, TWL4030 will be reset when a warm reset occures, and OMAP3530 does not hang on reboot. Let's add device tree support and configure things for warm reset as the default when compatible = "ti,twl4030-power". More complicated configurations can be added to the driver based on other compatible flags. Note we now also make the pdata const like it should be. This allows use it for match->data with the device tree related functions. Based on earlier patch by Matthias Brugger <matthias.bgg@gmail.com> and Lesly A M <leslyam@ti.com>.

By reading the touchscreen configuration from the settings that the maXTouch chip is actually using, we can remove some platform data. The matrix size is not used for anything, and results in some rather confusing code to re-read it because it may change when configuration is downloaded, so don't print it out.

The configuration is stored in NVRAM on the maXTouch chip. When the device is reset it reports a CRC of the stored configuration values. Therefore it isn't necessary to send the configuration on each probe - we can check the CRC matches and avoid a timeconsuming backup/reset cycle.

* The mapping of the GPIO numbers into the T19 status byte varies between different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array of up to 8 items is simpler and more generic. So replace #define with configurable number of keys which also allows the removal of is_tp. * Rename platform data parameters to include "t19" to prevent confusion with T15 key array. * Probe aborts early on when pdata is NULL, so no need to check. * Move "int i" to beginning of function (mixed declarations and code) * Use API calls rather than __set_bit() * Remove unused dev variable.

It is not necessary to download these values to the maXTouch chip on every probe, since they are stored in NVRAM. It makes life difficult when tuning the device to keep them in sync with the config array/file, and requires a new kernel build for minor tweaks. These parameters only represent a tiny subset of the available configuration options, tracking all of these options in platform data would be a endless task. In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all. Having these values also makes life more complex for device tree and other platforms where having to define a static configuration isn't helpful.

If the regcache is enabled on the regmap module drivers might need to access to HW register(s) in certain cases in cache bypass mode. As an example of this is the audio block's ANAMICL register. In normal operation the content can be cached but during initialization one bit from the register need to be monitored. With the twl_set_regcache_bypass() the client driver can switch regcache bypass on and off when it is needed so we can utilize the regcache for more registers.

Used the generic PHY framework API to create the PHY. For powering on and powering off the PHY, power_on and power_off ops are used. Once the MUSB OMAP glue is adapted to the new framework, the suspend and resume ops of usb phy library will be removed. Also twl4030-usb driver is moved to drivers/phy/. However using the old usb phy library cannot be completely removed because otg is intertwined with phy and moving to the new framework completely will break otg. Once we have a separate otg state machine, we can get rid of the usb phy library.

This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.

To enter high speed mode, following steps should be done: 1. When running in high speed mode, i2c clock rate is different from standard mode. Clock rate must be set according to specification first. 2. When i2c controller sends a master code and wins arbitration, high speed mode is entered. If you want to enable high speed mode, the following members of platform data should be set to proper value: 1. "high_mode" should be set to "1". 2. "master_code" should be set to "8'b 0000_1xxx"(x is 0 or 1). If no master_code is set, set to default value 0xe. 3. "rate" should be set according to specification.

Driver twl4030-madc has hardcoded channel types (10 - battery current, 1 - battery temperature) and also conversation data in variable twl4030_divider_ratios. These hardcoded channels are incorrect for Nokia RX-51 board (where is channel 0 - battery temperature). For Nokia RX-51 there is rx51_battery power_supply driver which reporting battery information via twl4030_madc_conversion. But this driver needs raw values (not converted via some hardcoded functions). So this patch adding new parameter "raw" to struct twl4030_madc_request which tell twl4030-madc driver to not convert values, but rather return raw.

This same driver can be used by atmel based touchscreens and touchpads (buttonpads). Platform data may specify a device is a touchpad using the is_tp flag. This will cause the driver to perform some touchpad specific initializations, such as: * register input device name "Atmel maXTouch Touchpad" instead of Touchscreen. * register BTN_LEFT & BTN_TOOL_* event types. * register axis resolution (as a fixed constant, for now) * register BUTTONPAD property * process GPIO buttons using reportid T19 Input event GPIO mapping is done by the platform data key_map array. key_map[x] should contain the KEY or BTN code to send when processing GPIOx from T19. To specify a GPIO as not an input source, populate with KEY_RESERVED, or 0.

On newer SH-/R-Mobile SoCs, a clock supply to the I2C hardware block, which is used to generate the SCL clock output, is getting faster than before, while on the other hand, the SCL clock control registers, ICCH and ICCL, stay unchanged in 9-bit-wide (8+1). On such silicons, the internal SCL clock counter gets incremented every 2 clocks of the operating clock. This patch makes it configurable through platform data.

Pull i2c-embedded changes from Wolfram Sang:
"The changes for i2c-embedded include:
- massive rework of the omap driver
- massive rework of the at91 driver. In fact, the old driver gets
removed; I am okay with this approach since the old driver was
depending on BROKEN and its limitations made it practically
unusable, so people used bitbanging instead. But even if there are
users, there is no platform_data or module parameter which would
need to be converted. It is just another driver doing I2C
transfers, just way better. Modifications of arch/arm/at91 related
files have proper acks from the maintainer.
- new driver for R-Car I2C
- devicetree and generic_clock conversions and fixes
- usual driver fixes and changes.
The rework patches have come a long way and lots of people have been
involved in creating/testing them. Most patches have been in
linux-next at least since 3.6-rc5. A few have been added in the last
week, I have to admit.
An unexpected (but welcome :)) peak in private life is the cause for
that. The "late" patches shouldn't cause any merge conflicts and I
will have a special eye on them during the stabilization phase. This
is an exception and I want to have the patches in place properly in
time again for the next kernels."
