mfd: twl4030-power: Add support for board specific configuration

2014-05-28T07:06:04Z

With the recommended twl4030 configuration added, we can now add board specific changes as modifications to the recommended configuration. Note that the data is private to this driver, and the data must always have a NULL resource in the sentinel. Signed-off-by: Tony Lindgren Signed-off-by: Lee Jones

mfd: twl4030-power: Add generic reset configuration

2014-05-28T07:05:32Z

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 and Lesly A M . Signed-off-by: Tony Lindgren Signed-off-by: Lee Jones

Input: atmel_mxt_ts - read screen config from chip

2014-05-27T02:08:21Z

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.

Input: atmel_mxt_ts - implement CRC check for configuration data

2014-05-19T06:27:26Z

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.

Input: atmel_mxt_ts - improve T19 GPIO keys handling

2014-05-19T06:27:22Z

* 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.

Input: atmel_mxt_ts - remove unnecessary platform data

2014-05-19T06:27:21Z

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.

Pull i2c updates from Wolfram Sang: "Here is the pull request from the i2c subsystem. It got a little delayed because I needed to wait for a dependency to be included (commit b424080a9e08: "reset: Add optional resets and stubs"). Plus, I had some email problems. All done now, the highlights are: - drivers can now deprecate their use of i2c classes. That shouldn't be used on embedded platforms anyhow and was often blindly copy&pasted. This mechanism gives users time to switch away and ultimately boot faster once the use of classes for those drivers is gone for good. - new drivers for QUP, Cadence, efm32 - tracepoint support for I2C and SMBus - bigger cleanups for the mv64xxx, nomadik, and designware drivers And the usual bugfixes, cleanups, feature additions. Most stuff has been in linux-next for a while. Just some hot fixes and new drivers were added a bit more recently." * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (63 commits) i2c: cadence: fix Kconfig dependency i2c: Add driver for Cadence I2C controller i2c: cadence: Document device tree bindings Documentation: i2c: improve section about flags mangling the protocol i2c: qup: use proper type fro clk_freq i2c: qup: off by ones in qup_i2c_probe() i2c: efm32: fix binding doc MAINTAINERS: update I2C web resources i2c: qup: New bus driver for the Qualcomm QUP I2C controller i2c: qup: Add device tree bindings information i2c: i2c-xiic: deprecate class based instantiation i2c: i2c-sirf: deprecate class based instantiation i2c: i2c-mv64xxx: deprecate class based instantiation i2c: i2c-designware-platdrv: deprecate class based instantiation i2c: i2c-davinci: deprecate class based instantiation i2c: i2c-bcm2835: deprecate class based instantiation i2c: mv64xxx: Fix reset controller handling i2c: omap: fix usage of IS_ERR_VALUE with pm_runtime_get_sync i2c: efm32: new bus driver i2c: exynos5: remove unnecessary cast of void pointer ...
