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.

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: NTony Lindgren <tony@atomide.com> Signed-off-by: NLee Jones <lee.jones@linaro.org>

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.

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>.

* 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.

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.

For Nokia RX-51 there is rx51_battery power_supply driver which reporting battery information via twl4030_madc_conversion.
