2013-04-08Merge tag 'ux500-multiplatform-mfd' of ↵Samuel Ortiz14-417/+454
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson MFD portions of the ux500 multiplatform branch. A second tag for the ARM SoC tree will build upon this one. This mainly removes the header file dependencies from the PRCMU driver in the MFD subsystem, and moves the PM functions to the machine. Signed-off-by: Samuel Ortiz <[email protected]>
2013-04-08power: rx51_battery: Fix reporting correct valuesPali Rohár1-0/+1
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).

2013-04-08mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversionPali Rohár2-4/+12
Driver twl4030-madc has hardcoded channel types (10 - battery current, 1 - battery temperature) and also conversation data in variable twl4030_divider_ratios. These hardcoded channels are incorrect for Nokia RX-51 board (where is channel 0 - battery temperature). For Nokia RX-51 there is rx51_battery power_supply driver which reporting battery information via twl4030_madc_conversion. But this driver needs raw values (not converted via some hardcoded functions). So this patch adding new parameter "raw" to struct twl4030_madc_request which tell twl4030-madc driver to not convert values, but rather return raw.

This untangles the final bits of the prcmu code from the platform code: * The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c because they are only of local significance. * u8500_thsens_device goes into the prcmu, because it uses a PRCMU IRQ that the platform does not see. * IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data because the PRCMU does not see it.

2013-04-08ARM: ux500: move PM-related PRCMU functions to machineLinus Walleij9-174/+195
We are trying to decompose and decentralize the code in the DB8500 PRCMU out into subdrivers. The code moved in this patch concerns a group of functions used for decoupling and recoupling the IRQs from the GIC. During sleep and idle the Ux500 system will transfer all IRQ handling to the PRCMU using these functions. Basically we are left with the two alternatives of code placement as: - arch/arm/mach-ux500/pm.c - this because the code is closely related to the GIC, and takes ownership of some of the registers from the PRCMU related to this PM functionality. - drivers/mfd/db8500-prcmu-pm.c - because the code is affecting stuff in the PRCMU register range. But then this code needs to remap and handle GIC registers. This patch implementation is taking the first approach. Currently the cpuidle driver is the only piece of code using this set of functions, but it will later also be used by the suspend/resume code which is currently under review. The header file is moved to: <linux/platform_data/arm-ux500-pm.h> The function prototypes need to be placed in a globally visible header since the CPUidle code is planned to move out to drivers/cpuidle.

2013-04-08mfd: db8500-prcmu: get base address from resourceLinus Walleij5-130/+131
We cannot use a global variable stored in <mach/hardware.h> to find the base address of the PRCMU. The real resource is already there from the board, so use this to look up the base address instead. Currently the patch is kept minimal so as not to interfere with other work being done on refactoring this driver, but at a later point the defines using (prcmu_base + 0xnnn) need to be replaced by pure offset defined for (0xnnn) and the base inlined with the readl()/writel() and similar codepaths.

2013-04-08mfd: prcmu: pass a base and size with the early initcallLinus Walleij4-12/+26
This patch will make an early remapping of the PRCMU, to be used when setting up the clocks, that will call down into parts of the PRCMU driver before it is probed. Going forward this will be removed like this: - The mailbox subsystem need to be merged. http://marc.info/?l=linux-kernel&m=136314559201983&w=2 - At this point the PRCMU clock code can be moved over to the ux500 clock driver in drivers/clk/ux500/* and maintained there in a decentralized manner. - This early initcall and PRCMU base parameters become part of the ux500_clk_init() call instead.
