* gpio: sx150x: move platform data into driverLinus Walleij2016-04-14
| | | | | | | | | | | The sx150x has some platform data definition in <linux/i2c/sx150x.h> but this file is only included from the driver in the whole kernel so move its contents into the driver.

* i2c: rcar: Remove obsolete platform data supportGeert Uytterhoeven2015-10-20
| | | | | | | | | | | Since commit 4baadb9e05c68962 ("ARM: shmobile: r8a7778: remove obsolete setup code"), Renesas R-Car SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to use platform data anymore, hence remove platform data configuration.

* Input: atmel_mxt_ts - use deep sleep mode when stoppedNick Dyer2015-08-04
| | | | | | | | | | | | | | | | | | | | | | | | The hardcoded 0x83 CTRL setting overrides other settings in that byte, enabling extra reporting that may not be useful on a particular platform. Implement improved suspend mechanism via deep sleep. By writing zero to both the active and idle cycle times the maXTouch device can be put into a deep sleep mode, using minimal power. It is necessary to issue a calibrate command after the chip has spent any time in deep sleep, however a soft reset is unnecessary. Use the old method on Chromebook Pixel via platform data option. This patch also deals with the situation where the power configuration is zero on probe, which would mean that the device never wakes up to execute commands. After a config download, the T7 power configuration may have changed so it is necessary to re-read it.

* mfd: twl4030-power: Fix pmic for boards that need AC charger disabledTony Lindgren2015-06-22
| | | | | | | | | | | | | | | | | I noticed the PMIC configuration on 37xx-evm won't actually shut down the voltages during off-idle. Turns out 37xx-evm needs the AC charger state transitions disabled like we are doing for SDP and LDP in the legacy booting case. Let's fix this for device tree based booting by setting up the quirk flag based on the compatible flag. And let's also use the existing define for STARTON_CHG. Note that SDP and EVM do not have the PMIC clken wired to gate the the oscillator while LDP has. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

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>.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 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.
