2013-09-28usb: phy: twl4030: use the new generic PHY frameworkKishon Vijay Abraham I1-0/+2
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.

2013-08-07i2c: pxa: enable high speed mode for i2c busLeilei Shang1-0/+3
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.

2013-04-08mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversionPali Rohár1-0/+2
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.

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.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This contains pretty many small commits covering fairly large range of files in sound/ directory. Partly because of additional API support and partly because of constantly developed ASoC and ARM stuff. Some highlights: - Introduced the helper function and documentation for exposing the channel map via control API, as discussed in Plumbers; most of PCI drivers are covered, will follow more drivers later - Most of drivers have been replaced with the new PM callbacks (if the bus is supported) - HD-audio controller got the support of runtime PM and the support of D3 clock-stop. Also changing the power_save option in sysfs kicks off immediately to enable / disable the power-save mode. - Another significant code change in HD-audio is the rewrite of firmware loading code. Other than that, most of changes in HD-audio are continued cleanups and standardization for the generic auto parser and bug fixes (HBR, device-specific fixups), in addition to the support of channel-map API. - Addition of ASoC bindings for the compressed API, used by the mid-x86 drivers. - Lots of cleanups and API refreshes for ASoC codec drivers and DaVinci. - Conversion of OMAP to dmaengine. - New machine driver for Wolfson Microelectronics Bells. - New CODEC driver for Wolfson Microelectronics WM0010. - Enhancements to the ux500 and wm2000 drivers - A new driver for DA9055 and the support for regulator bypass mode."

R-Car I2C is similar with SH7760 I2C. But the SH7760 I2C driver had many workaround operations, since H/W had bugs. Thus, it was pointless to keep compatible between SH7760 and R-Car I2C drivers.

Let I2C bus segments behind multiplexers have a class. This allows for device auto-detection on these segments. As long as parent segments don't share the same class, it should be fine. I implemented support in drivers i2c-mux-gpio and i2c-mux-pca954x. I left i2c-mux-pca9541 and i2c-mux-pinctrl alone for the moment as I don't know if this feature makes sense for the use cases of these drivers.

One of our patches added thermal support for power supply class, but thermal/ subsystem changed under our feet. We (well, Stephen, that is) caught the issue and it was decided[1] that I'd just delay the battery pull request, and then will fix it up by merging upstream back into battery tree at the specific commit. That's not all though: another[2] small fixup for thermal subsystem was needed to get rid of a warning in power supply subsystem (the warning was not drivers/power's "fault", the thermal registration function just needed a proper const annotation, which is also done by a small commit on top of the merge. So, to sum this up: - The 'master' branch of the battery tree was in the -next tree for weeks, was never rebased, altered etc. It should be all OK; - Although, for-v3.6 tag contains the 'master' branch + merge + the warning fix.

The polarity of Input ports can be reversed by setting the appropiate bit in Polarity Inversion registers.

These settings are disabled by default, but can be enabled with CONFIG_TWL4030_ALLOW_UNSUPPORTED=y However - that config variable is not mentioned in any Kconfig so cannot be used, and - a global setting is clumsy - a per regulator setting would be better.
