2020-11-19mfd: Constify static struct resourcesRikard Falkeborn1-25/+25
Constify a number of static struct resource. The only usage of the structs are to assign their address to the resources field in the mfd_cell struct. This allows the compiler to put them in read-only memory. Done with the help of Coccinelle.

2015-08-11mfd: Kill off set_irq_flags usageRob Herring1-4/+0
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

2014-03-19mfd: 88pm860x: Fix possible NULL pointer dereference on i2c_new_dummy errorKrzysztof Kozlowski1-0/+5
During probe the driver allocates dummy I2C device for companion chip with i2c_new_dummy() but it does not check the return value of this call. In case of error (i2c_new_device(): memory allocation failure or I2C address cannot be used) this function returns NULL which is later used by regmap_init_i2c(). If i2c_new_dummy() fails for companion device, fail also the probe for main MFD driver.

2012-09-16mfd: core: Push irqdomain mapping out into devicesMark Brown1-10/+11
Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

2012-09-11mfd: 88pm860x: Move _IO resources out of ioport_ioresourceMark Brown1-29/+63
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.

2012-03-06mfd: Add power control interface for pm8606 chipJett.Zhou1-0/+95
The reference group and internal oscillator are shared by sub-devs like led, backlight and vibrator in PM8606 chip. Now introduce a voting mechanism to enable/disable it. Add pm8606_osc_enable() and pm8606_osc_disable() interface and related defines to support this. This interface will be called by vibrator led and backlight driver.The refernce group and internal oscillator are enabled only when at least one of it's clients holds it on or disabled only all the clients don't use it any more based on the above mechanism.

Avoid to use constraint name in regulator driver. So use regulator id is used instead in platform driver.

Maybe multiple PMIC devices are installed into one board. Static variable can only make driver logic mess. So remove these variable, and use platform data from platform driver instead. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

WARNING: vmlinux.o(.devinit.text+0x6c4): Section mismatch in reference from the function device_onkey_init() to the (unknown reference) .init.data:(unknown) The function __devinit device_onkey_init() references a (unknown reference) __initdata (unknown). If (unknown) is only used by device_onkey_init then annotate (unknown) with a matching annotation. It's caused by using __initdata on mfd cell resources. Replace __initdata with __devinitdata.

2011-05-26mfd: Use mfd cell platform_data for 88pm860x cells platform bitsSamuel Ortiz1-6/+12
With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.
