regulator: TPS65910: Fix VDD1/2 voltage selector count

2011-11-23T14:03:52Z

Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed Signed-off-by: Mark Brown

mfd: Implement tps65910 IRQ cleanup

2011-07-31T21:28:23Z

The tps65910_irq_exit() cleanup function was generating a warning from sparse due to the lack of a prototype. This wasn't causing GCC warnings as the driver wasn't cleaning up its IRQs on exit at all so there was no use of an unprototyped function. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

treewide: fix potentially dangerous trailing ';' in #defined values/expressions

2011-07-21T12:10:00Z

All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem. (Thus things that are likely to be found in one of the contexts above, more complicated ones aren't.) Signed-off-by: Phil Carmody Signed-off-by: Jiri Kosina

TPS65911: Comparator: Add comparator driver

2011-05-27T09:49:29Z

This driver adds functionality to the tps65911 chip driver. Two of the comparators are configurable by software and measures VCCS voltage to detect high or low voltage scenarios. Signed-off-by: Jorge Eduardo Candelaria Acked-by: Samuel Ortiz Signed-off-by: Liam Girdwood

TPS65911: Add support for added GPIO lines

2011-05-27T09:49:29Z

GPIO 1 to 8 are added for TPS65911 chip version. The gpio driver now handles more than one gpio lines. Subsequent versions of the chip family can add new GPIO lines with minimal driver changes. Signed-off-by: Jorge Eduardo Candelaria Acked-by: Grant Likely Signed-off-by: Liam Girdwood

TPS65911: Add new irq definitions

2011-05-27T09:49:10Z

TPS65911 adds new interrupt sources, as well as two new registers to handle them, one for interrupt status and one for interrupt masking. The added irqs are: -VMBCH2 - Low and High threshold -GPIO1-8 - Rising and falling edge detection -WTCHDG - Watchdog interrupt -PWRDN - PWRDN reset interrupt The code should handle these new registers only when the chip version is TPS65911.

regulator: tps65911: Add new chip version

2011-05-27T09:49:10Z

The tps65911 chip introduces new features, including changes in the regulator module. - VDD1 and VDD2 remain unchanged. - VDD3 is now named VDDCTRL and has a wider voltage range. - LDOs are now named LDO1...8 and voltage ranges are sequential, making LDOs easier to handle.

MFD: TPS65910: Add support for TPS65911 device

2011-05-27T09:49:10Z

The TPS65911 is the next generation of the TPS65910 family of PMIC chips. It adds a few features: - Watchdog Timer - PWM & LED generators - Comparators for system control status It also adds a set of Interrupts and GPIOs, among other things. The driver exports a function to identify between different versions of the tps65910 family, allowing other modules to identify the capabilities of the current chip.

TPS65910: Add tps65910 regulator driver

2011-05-27T09:49:08Z

The regulator module consists of 3 DCDCs and 8 LDOs. The output voltages are configurable and are meant to supply power to the main processor and other components Signed-off-by: Graeme Gregory Signed-off-by: Jorge Eduardo Candelaria Acked-by: Mark Brown Signed-off-by: Liam Girdwood

TPS65910: IRQ: Add interrupt controller

2011-05-27T09:48:43Z

This module controls the interrupt handling for the tps chip.
