2014-03-19mfd: lpc_ich: Fix ACPI enable bitmaskPeter Tyser1-1/+1
The original bitmask of 0x10 was incorrect and would result in a write to a reserved read-only bit instead of enabling the ACPI I/O region. Update it to the proper value of 0x80.

2014-03-19mfd: twl-core: Fix accessibility of some twl4030 audio registersTomas Novotny1-5/+5
There are some unused registers in twl4030 at I2C address 0x49 and function twl4030_49_nop_reg() is used to check accessibility of that registers. These registers are written in decimal format but the values are correct in hexadecimal format. (It can be checked few lines above the patched code - these registers are marked as unused there.) As a consequence three registers of audio submodule are treated as inaccessible (preamplifier carkit right and both handsfree registers).

2014-03-19mfd: pm8xxx: Move pm8xxx-irq.c contents into only driver that uses itStephen Boyd5-405/+348
The pm8xxx-irq.c code is practically mandatory given that the pm8921-core driver will WARN about it missing and the Kconfig marks it as default y when a PM8xxx chips is enabled. The only reason the file was split out was because we planned to support other pm8xxx chips with different pm8xxx-core.c files. Now that we have DT on ARM this isn't necessary because we should be able to support all the ssbi based PM8xxx chips in one driver and one file with no data bloat. Let's move this code into the only driver that uses it right now (pm8921) so that it's always compiled when needed. In the future we can rename pm8921-core.c to something more generic.

This patch will remove the older variant code ID which matches the pre-production silicon ID (0x3) for the DA9063 chip. There is also some small amount of correction done in this patch: it splits the revision code and correctly names it according to the hardware specification and moves the dev_info() call before the variant ID test.
