2019-02-01mfd: max8925-core: Drop unused MODULE_ tags from non-modular codePaul Gortmaker1-6/+1
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_MAX8925 drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX8925 PMIC Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2015-08-11mfd: Kill off set_irq_flags usageRob Herring1-4/+1
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.

2012-09-14mfd: core: Push irqdomain mapping out into devicesMark Brown1-6/+6
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. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>

2012-09-11mfd: max8925: Move _IO resources out of ioport_ioresourceMark Brown1-0/+10
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.

In max8925_irq_sync_unlock(), irq control bit is set at the same time. Zero means enabling irq, and one means disabling irq.

2010-05-28mfd: Delay to mask tsc irq in max8925Haojian Zhuang1-2/+5
There're two IRQ pins output from MAX8925. One is PMIC interrupt, the other is TSC interrupt. But they're sharing one irq chip. After initializing MAX8925 interrupts, unexpected TSC interrupt may occur and it can't be cleared if touch driver isn't loaded. Now move the operation of masking TSC interrupt behind requesting PMIC interrupt. If touch driver isn't loaded, this interrupt is always masked.
