* mfd: remove use of __devinitBill Pemberton2012-11-281-10/+10
| | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option so __devinit is no longer needed.

* ARM: omap: fix section mismatch errors in TWL PMIC driverRussell King2012-02-131-10/+10
| | | | | | | | | | | | | | WARNING: drivers/mfd/built-in.o(.devinit.text+0x258): Section mismatch in reference from the function twl_probe() to the function .init.text:twl4030_power_init() The function __devinit twl_probe() references a function __init twl4030_power_init(). If twl4030_power_init is only used by twl_probe then annotate twl4030_power_init with a matching annotation. twl4030_power_init() references other __init marked functions, so these too must become __devinit.

* mfd: Add power off functionality to TWLIgor Grinberg2012-01-091-2/+40
| | | | | | | | | | | | TWL family of PMICs, used in master mode, have a power off functionality. The resulting power off sequence shuts down all the SoC supplies, LDOs, etc. The sequence is described in the datasheets chapter "Power-Off Sequence". Note, that board must be wired correctly for the power off to work as expected. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* mfd: Correct the twl4030-power warning print during script loadingLesly A M2011-05-261-1/+1
| | | | | | | | | | | | | | | Correcting the if condition check for printing the warning, if wakeup script is not updated before updating the sleep script. Since the flag 'order' is set to '1' while updating the wakeup script for P1P2, the condition checking for printing the warning should be if(!order) (ie: print the warning if wakeup script is not updated before updating the sleep script) Signed-off-by: Lesly A M <leslyam@ti.com> Cc: Nishanth Menon <nm@ti.com> Cc: David Derrick <dderrick@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* mfd: Introduce remove_script function for twl4030Mike Turquette2010-03-071-0/+50
| | | | | | | | | | | | | New function twl4030_remove_script(u8 flags) takes a script type as defined in twl.h and prevents any script already loaded in that position from running. This is accomplished by programming SEQ_ADD_* to 0x3f, the END_OF_SCRIPT value, where SEQ_ADD_* is determined by flags. (Future) users of this function include OMAP board files for machines facing a race condition between sleep and warm reset.

* mfd: Fix more undefined twl4030-power resconfig value checksAmit Kucheria2009-12-131-2/+2
| | | | | | | | | | | | | | | | | Based on Aaro's previous fix, this needs to be fixed for the newly added remap_off and remap_sleep resources as well. The code tries to skip values initialized with -1, but since the values are unsigned the comparison is always true. The patch eliminates the following compiler warnings: drivers/mfd/twl4030-power.c: In function 'twl4030_configure_resource': drivers/mfd/twl4030-power.c:338: warning: comparison is always true due to limited range of data type Signed-off-by: Amit Kucheria <amit.kucheria@verdurent.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* mfd: Print warning for twl4030 out-of-order script loadingAmit Kucheria2009-09-171-0/+6
| | | | | | | | | | | | | | | | | When the sleep script is loaded before the wakeup script, there is a chance that the system might go to sleep before the wakeup script loading is completed. This will lead to a system that does not wakeup and has been observed to cause non-booting boards. Various options were considered to solve this problem, including modification of the core twl4030 power code to be smart enough to reorder the loading of the scripts. But it felt too over-engineered. Hence this patch just warns the DPS script developer so that they may be reordered in the board-code itself.

* mfd: Add support for TWL4030/5030 dynamic power switchingAmit Kucheria2009-09-171-0/+466
The TWL4030/5030 family of multifunction devices allows board-specific control of the the various regulators, clock and reset lines through 'scripts' that are loaded into its memory. This allows for Dynamic Power Switching (DPS). Implement board-independent core support for DPS that is then used by board-specific code to load custom DPS scripts.
