2014-01-21mfd: max77693: Set proper maximum register for MUIC regmapKrzysztof Kozlowski1-1/+7
The MUIC block in max77693 has different I2C address than PMIC. The driver allocated two regmaps: for PMIC and MUIC. However it used the same regmap_config (with max_register field) for both regmaps. Actual maximum address of register for MUIC is different than for PMIC. Define another regmap_config for MUIC with proper max_register value.

The regmap used by max77686 MFD driver was not freed with regmap_exit() on driver exit. This lead to leak of resources. Replace regmap_init_i2c() call in driver probe with initialization of managed register map so the regmap will be properly freed by the device management code.

2014-01-21mfd: Always assign of_node in mfd_add_device()Stephen Warren1-0/+2
mfd_add_device() assigns .of_node in the device objects it creates only if the mfd_cell for the device has the .of_compatible field set and the DT node for the top-level MFD device contains a child whose compatible property matches the cell's .of_compatible field. This leaves .of_node unset in many cases. When this happens, entries in the DT /aliases property which refer to the top-level MFD DT node will never match the MFD child devices, hence causing the requested alias not to be honored. Solve this by setting each MFD child device's .of_node equal to the top- level MFD device's .of_node field in the cases where it would otherwise remain unset. The first use-case for this will be aliases for the TPS6586x's RTC device. Signed-off-by: Stephen Warren <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2014-01-21mfd: cros ec: spi: Add delay for raising CSRhyland Klein2-0/+38
The EC has specific timing it requires. Add support for an optional delay after raising CS to fix timing issues. This is configurable based on a DT property "google,cros-ec-spi-msg-delay". If this property isn't set, then no delay will be added. However, if set it will cause a delay equal to the value passed to it to be inserted at the end of a transaction.

2014-01-21regulator: tps6586x: Add and use correct voltage tableStefan Agner2-21/+76
Depending on the regulator version, the voltage table might be different. Use version specific regulator tables in order to select correct voltage table. For the following regulator versions different voltage tables are now used: * TPS658623: Use correct voltage table for SM2 * TPS658643: New voltage table for SM2 Both versions are in use on the Colibri T20 module. Make use of the correct tables by requesting the correct SM2 voltage of 1.8V. This change is not backward compatible since an old driver is not able to correctly set that value. The value 1.8V is out of range for the old driver and will refuse to probe the device. The regulator starts with default settings and the driver shows appropriate error messages. On Colibri T20, the old value used to work with TPS658623 since the driver applied a wrong voltage table too. However, the TPS658643 used on V1.2 devices uses yet another voltage table and those broke that pseudo-compatibility. The regulator driver now has the correct voltage table for both regulator versions and those the correct voltage can be used in the device tree.

This is the other of the LP3943 MFD driver. LP3943 can be used as a PWM generator, up to 2 channels. * Two PWM generators supported * Supported PWM operations request, free, config, enable and disable * Pin assignment A driver data, 'pin_used' is checked when a PWM is requested. If the output pin is already assigned, then returns as failure. If the pin is available, 'pin_used' is set. When the PWM is not used anymore, then it is cleared. It is defined as unsigned long type for atomic bit operation APIs, but only LSB 16bits are used because LP3943 has 16 outputs.

LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver.

This is one of LP3943 MFD driver. LP3943 is configurable as a GPIO expander, up to 16 GPIOs. * Application note: how to configure LP3943 as a GPIO expander http://www.ti.com/lit/an/snva287a/snva287a.pdf * Supported GPIO controller operations request, free, direction_input, direction_output, get and set * GPIO direction register not supported LP3943 doesn't have the GPIO direction register. It only provides input and output status registers. So, private data for the direction should be handled manually. This variable is updated whenever the direction is changed and used in 'get' operation. * Pin assignment A driver data, 'pin_used' is checked when a GPIO is requested. If the GPIO is already assigned, then returns as failure. If the GPIO is available, 'pin_used' is set. When the GPIO is not used anymore, then it is cleared. It is defined as unsigned long type for atomic bit operation APIs, but only LSB 16bits are used because LP3943 has 16 outputs.
