db15e6312e rx51_battery: Fix channel number when reading adc value
This issue was introduced in commit 8e2747f031 "power: rx51_battery:
Replace hardcoded channels values."

Original code use channel as argument which was shifted by one in
function. After mentioned commit argument is already shifted so we need to
get index back.

8e2747f031 rx51_battery: Replace hardcoded channels values.
In twl4030_madc header exist defines for fixed channels + add rx51
specific channels and replace all hardcoded channels values.

f70d739ada rx51_battery: Remove unnecessary platform_set_drvdata()
The driver core clears the driver data to NULL after device_release or on
probe failure, since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is
not needed to manually clear the device driver data to NULL.

d7ab7302f9 For 3.10 we have a few new MFD drivers for:
- The ChromeOS embedded controller which provides keyboard, battery and power
   management services. This controller is accessible through i2c or SPI.
 
 - Silicon Laboratories 476x controller, providing access to their FM chipset
   and their audio codec.
 
 - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader.
 
 - Nokia's Tahvo power button and watchdog device. This device is very similar
   to Retu and is thus supported by the same code base.
 
 - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by
   the stmpe driver.
 
 - ST-Ericsson AB8540 and AB8505 power management and voltage converter
   controllers through the existing ab8500 code.
 
 Some other drivers got cleaned up or improved. In particular:
 
 - The Linaro/STE guys got the ab8500 driver in sync with their internal code
   through a series of optimizations, fixes and improvements.
 
 - The AS3711 and OMAP USB drivers now have DT support.
 
 - The arizona clock and interrupt handling code got improved.
 
 - The wm5102 register patch and boot mechanism also got improved.

8059c1c6be power: rx51_battery: Fix reporting correct values
Tell twl4030_madc_conversion that this driver needs raw values.
Driver twl4030_madc has some hardcoded values and conversation
functions which are incorrect for Nokia RX-51 board. This driver
rx51_battery expects raw values which convert itself.

This patch fixing values reported by power supply interface.
Before this patch driver reported always incorrect values on
3.8 kernel (sometimes design capacity was negative).

6d2cea4fca Drivers: power: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitconst,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
