2015-08-07Input: max77693: Add support for Maxim 77843Krzysztof Kozlowski1-3/+45
The Maxim 77843 haptic driver differs from 77693 by: 1. Setting the bias. 2. Different configuration register. 3. Not enabling the low-sys DAC. 4. Using same regmap for PMIC and haptic blocks. Incorporate all differences into max77693 haptic driver so both devices can be supported.

2015-08-07Input: max77693: Prepare for adding support for Maxim 77843Krzysztof Kozlowski1-7/+34
Prepare the driver for supporting two devices: Maxim 77693 and 77843: 1. Add table of device ids and store current device type for later usage. 2. Differentiate the haptic device configuration.

2015-08-07Input: max77693: Remove a read-only pwm_divisor fieldKrzysztof Kozlowski1-3/+1
Storing a predefined PWM divisor in state container structure is meaningless. The field, after initialization, is only read so this only obfuscates the code. Remove the field and use directly enum value.

2015-07-16drivers: max77693: Move state container to common headerKrzysztof Kozlowski1-0/+1
This prepares for merging some of the drivers between max77693 and max77843 so the child MFD driver can be attached to any parent MFD main driver. Move the state container to common header file. Additionally add consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input subsystem updates from Dmitry Torokhov: "Two new drivers for Elan hardware (for I2C touchpad and touchscreen found in several Chromebooks and other devices), a driver for Goodix touch panel, and small fixes to Cypress I2C trackpad and other input drivers. Also we switched to use __maybe_unused instead of gating suspend/ resume code with #ifdef guards to get better compile coverage" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (27 commits) Input: gpio_keys - fix warning regarding uninitialized 'button' variable Input: add support for Elan eKTH I2C touchscreens Input: gpio_keys - fix warning regarding uninitialized 'irq' variable Input: cyapa - use 'error' for error codes Input: cyapa - fix resuming the device Input: gpio_keys - add device tree support for interrupt only keys Input: amikbd - allocate temporary keymap buffer on the stack Input: amikbd - fix build if !CONFIG_HW_CONSOLE Input: lm8323 - missing error check in lm8323_set_disable() Input: initialize device counter variables with -1 Input: initialize input_no to -1 to avoid subtraction Input: i8042 - do not try to load on Intel NUC D54250WYK Input: atkbd - correct MSC_SCAN events for force_release keys Input: cyapa - switch to using managed resources Input: lifebook - use "static inline" instead of "inline" in lifebook.h Input: touchscreen - use __maybe_unused instead of ifdef around suspend/resume Input: mouse - use __maybe_unused instead of ifdef around suspend/resume Input: misc - use __maybe_unused instead of ifdef around suspend/resume Input: cap11xx - support for irq-active-high option Input: cap11xx - add support for various cap11xx devices ...

2014-11-02Input: misc - use __maybe_unused instead of ifdef around suspend/resumeJingoo Han1-4/+2
Use __maybe_unused instead of ifdef guards around suspend/resume functions, in order to increase build coverage and fix build warnings. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-10-31Input: max77693-haptic - fix potential overflowDmitry Torokhov1-3/+2
Expression haptic->pwm_dev->period * haptic->magnitude is of type 'unsigned int' and may overflow. We need to convert one of the operands to u64 before multiplying, instead of casting result (potentially overflown) to u64.
