This patch will enable probing to occur during a Device Tree enabled boot. The IRQ base is expected to be located in and will be fetched from the DT itself. We also prevent any of the db8500 regulators from being registered here, as they will be enabled via DT instead.

The driver still uses a custom cache implementation but the underlying physical I/O is now done using the regmap API, saving some code and avoiding allocating enormous scratch arrays on the stack.

The removal of mach/io.h from most ARM platforms also set the range of valid IO ports to be empty for most platforms when previously any 32 bit integer had been valid. This makes it impossible to add IO resources as the added range is smaller than that of the root resource for IO ports. Since we're not really using IO memory at all fix this by defining our own root resource outside the normal tree and make that the parent of all IO resources. This also ensures we won't conflict with read IO ports if we ever run on a platform which happens to use them.

A warning was being generated by the reference from tps65910_i2c_probe() to tps65910_sleepinit() since the latter was annotated as __init but the former was unannotated. Since these functions can only be called during device init make them both __devinit, and while we're at it also annotate tps65910_i2c_remove() __devexit for symmetry.

This patch makes it possible to disable battery management via a module boot parameter. When 'ab8500-core.no_bm=1' then ab8500_btemp, ab8500_chargalg, ab8500_charger and ab8500_fg will not be probed. This boot parameter is used for scripted testing of the system.

This change converts the mc13xxx core to use regmap rather than direct spi r/w. The spidev member of mc13xxx struct becomes redundant and is removed. Extra debugging aids are added to mc13xxx_reg_rmw. Mutex init is moved to before regmap init.

This patch abstracts the bus specific operations from the driver core. Generic init and cleanup is consolidated into mc13xxx_common_*. spi specific functions are renamed to reflect such. (The irq member of the mc13xxx struct is no longer redundant, it's used to store the irq for cleanup time).

The mfd/asic3 driver does not currently define a irq_set_wake() handler. Consequently any attempt to configure the 3 ASIC3 GPIO buttons - RECORD, CALENDAR, HOME - as wakeup sources results in Unbalanced IRQ warnings when the system is woken from sleep mode: WARNING: at kernel/irq/manage.c:520 irq_set_irq_wake+0xc4/0xf8() Unbalanced IRQ 342 wake disable ...

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment.

The mfd/asic3 driver does not set the ds1wm_driver_data clock_rate field before passing the structure to the DS1WM w1 busmaster driver. This was not noticed before commit 26a6afb9, because ds1wm_find_divisor() unintentionally returned the correct divisor when a zero clock_rate was passed in. However after that commit DS1WM fails a zero clock_rate: ds1wm ds1wm: no suitable divisor for 0Hz clock This patch sets the ds1wm_driver_data clock_rate field.

This driver works on many Intel chipsets, including the ICH6, ICH7, ICH8, ICH9, ICH10, 3100, Series 5/3400 (Ibex Peak), Series 6/C200 (Cougar Point), and NM10 (Tiger Point). Additional Intel chipsets should be easily supported if needed, eg the ICH1-5, EP80579, etc. Tested on QM67 (Cougar Point), QM57 (Ibex Peak), 3100 (Whitmore Lake), and NM10 (Tiger Point).

As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.
