mfd: ab8500: Debugfs code depends on gpadc

2013-05-16T22:42:29+00:00

The AB8500_DEBUG code specifically requires access to the gpadc code,
not just the common ab8500 driver.

drivers/built-in.o: In function `ab8500_gpadc_bat_ctrl_print':
 mfd/ab8500-debugfs.c:1733: undefined reference to `ab8500_gpadc_get'

mfd: tps65912: Select MFD_CORE

CONFIG_MFD_CORE must be selected for TPS65912 to properly buid.
Otherwise it results in a link error:

Merge tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

2013-05-06T00:36:20+00:00

Pull MFD update from Samuel Ortiz:
"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."

mfd: si476x: Add header files and Kbuild plumbing

2013-04-19T16:38:13+00:00

This patch adds all necessary header files and Kbuild plumbing for the
core driver for Silicon Laboratories Si476x series of AM/FM tuner
chips.

The driver as a whole is implemented as an MFD device and this patch
adds a core portion of it that provides all the necessary
functionality to the two other drivers that represent radio and audio
codec subsystems of the chip.

mfd: retu: Add Tahvo support

2013-04-18T22:45:20+00:00

Tahvo is a multi-function device on Nokia 770, implementing USB
transceiver and charge/battery control.

It's so close to Retu that a single driver can support both.

mfd: Kconfig alphabetical re-ordering

Ordering so many Kconfig alphabetically makes it a lot easier to read e.g.
from menuconfig.

2013-04-09T12:15:58+00:00

Provides support for 1801 variant of stmpe gpio port expanders.
This chip has 18 gpios configurable as GPI, GPO, keypad matrix,
special key or dedicated key function.

Note that special/dedicated key function is not supported yet.

mfd: Remove twelve unused Kconfig symbols

2013-04-09T08:14:00+00:00

Twelve Kconfig symbols, all related to WM8350, WM8351, and WM8352, are
unused. Commit 19d57ed5a308472a02e773f33c03ad4cb2ec6a9 ("mfd: Remove
custom wm8350 cache implementation") removed all their (actual) users.
Remove these symbols too.

mfd: da9055: Drop "select PMIC_DA9055"

2013-04-08T16:56:06+00:00

The Kconfig entry for DA9055 PMIC Support selects PMIC_DA9055. That was
probably inspired by the similar select statement in the entry for
DA9052/53 PMIC with I2C. But the DA9055 PMIC only comes in an I2C
variant and its driver doesn't need a separate Kconfig symbol for shared
code. In any case, this select can be dropped as PMIC_DA9055 doesn't
exist.

mfd: abx500: Move the AB8500 Kconfig fragment

2013-04-05T16:10:30+00:00

Move the AB8500 Kconfig fragment below the AB3100 so the
menuconfig menu gets hierarchically nested and looks nice.
Having the EZX PCAP in the middle disturbs the nice
hierarchical layout from kconfig.
