2012-06-04mfd: Fix tps65910 build failureSamuel Ortiz
The tps65910_parse_dt() prototype for !CONFIG_OF was not correct, leading to: drivers/mfd/tps65910.c: In function ‘tps65910_i2c_probe’: drivers/mfd/tps65910.c:218:3: error: too many arguments to function ‘tps65910_parse_dt’ Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> (cherry picked from commit 7f65f74ccee15f6eb0009921a428e3c5d5d06ae0) Change-Id: I1592020268c408effc331069b7ae241c6da248bb Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Reviewed-on: http://git-master/r/105927 GVS: Gerrit_Virtual_Submit
2012-06-04mfd: Register tps65910 gpios as an mfd deviceLaxman Dewangan

2012-06-04mfd: Cache tps65910 register when we need itLaxman Dewangan
During regmap initialization, we do not provide the default value and hence in place of caching register during regmap_init(), cache it when actually we need it i.e. after reading of that register.

2012-06-04mfd: Fix tps65910 section annotationsMark Brown
A warning was being generated by the reference from tps65910_i2c_probe() to tps65910_sleepinit() since the latter was annotated as __init but the former was unannotated. Since these functions can only be called during device init make them both __devinit, and while we're at it also annotate tps65910_i2c_remove() __devexit for symmetry.

2012-02-28mfd: Use regmap for tps65910 register access.Laxman Dewangan
Using regmap apis for accessing the device registers and using RBTREE caching mechanims for caching registers. Enabling caching of the registers which is used for voltage controls. By doing this, the modify_bits operation is faster as it does not involve the i2c register read from device, just read from cache. This results faster set voltage operation.

2011-07-31mfd: Avoid two assignments if failures happen in tps65910_i2c_probeJesper Juhl
In drivers/mfd/tps65910.c:tps65910_i2c_probe() there's potential for a tiny optimization. We assign to init_data->irq and init_data->irq_base long before we need them, and there are two potential exits from the function before they are needed. Moving the assignments below these two potential exits means we completely avoid doing them in these two (failure) cases.

2011-07-31mfd: Implement tps65910 IRQ cleanupMark Brown
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.

2011-05-27MFD: TPS65910: Add support for TPS65911 deviceJorge Eduardo Candelaria
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.
