efb5a790 - mfd: wm831x-core: Drop unused module infrastructure from non-modular code

Sun, 13 Jan 2019 18:36:46 +0000

mfd: wm831x-core: Drop unused module infrastructure from non-modular codeThe Kconfig currently controlling compilation of this code is:drivers/mfd/Kconfig:config MFD_WM831Xdrivers/mfd/Kconfig: bool...meaning that it currently is not being built as a module by anyone.Lets remove the couple traces of modular infrastructure use, so thatwhen reading the driver there is no doubt it is builtin-only.We delete the MODULE_LICENSE tag etc. since all that informationis already contained at the top of the file in the comments.Previous demodularizaion work has made wm831x_device_exit() no longerused, so it is also removed from the 831x core code.Signed-off-by: Paul Gortmaker Acked-by: Charles Keepax Signed-off-by: Lee Jones List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

cd99758b - mfd: Convert wm831x to irq_domain

Mon, 14 May 2012 21:14:24 +0000

mfd: Convert wm831x to irq_domainThe modern idiom is to use irq_domain to allocate interrupts. This isuseful partly to allow further infrastructure to be based on the domainsand partly because it makes it much easier to allocate virtual interruptsto devices as we don't need to allocate a contiguous range of interruptnumbers.Convert the wm831x driver over to this infrastructure, using a legacyIRQ mapping if an irq_base is specified in platform data and otherwiseusing a linear mapping, always registering the interrupts even if theywon't ever be used. Only boards which need to use the GPIOs asinterrupts should need to use an irq_base.This means that we can't use the MFD irq_base management since theunless we're using an explicit irq_base from platform data we can't relyon a linear mapping of interrupts. Instead we need to map things viathe irq_domain - provide a conveniencem function wm831x_irq() to save asmall amount of typing when doing so. Looking at this I couldn't clearlysee anything the MFD core could do to make this nicer.Since we're not supporting device tree yet there's no meaningfuladvantage if we don't do this conversion in one, the fact that theinterrupt resources are used for repeated IP blocks makes accessorfunctions for the irq_domain more trouble to do than they're worth.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

7583a213 - mfd: Simulate active high IRQs with wm831x

Fri, 16 Sep 2011 12:21:47 +0000

mfd: Simulate active high IRQs with wm831xIn order to ease system integration provide a simulation of active highIRQs on the GPIOs by polling the GPIO status when an IRQ is generated.This isn't ideal on several fronts and will miss initially active IRQs inthe current implementation but it should work well for most cases.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

5da721c8 - mfd: Support software initiated shutdown of WM831x PMICs

Thu, 15 Sep 2011 16:54:53 +0000

mfd: Support software initiated shutdown of WM831x PMICsIn systems where there is no hardware signal from the processor to thePMIC to initiate the final power off sequence we must initiate theshutdown with a register write to the PMIC. Support such systems in thedriver. Since this may prevent a full shutdown of the system platformdata is used to enable the feature.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

1df5981b - mfd: Convert WM831x to use regmap API

Fri, 10 Jun 2011 18:28:10 +0000

mfd: Convert WM831x to use regmap APIFactor out the register read/write code to use the register map API. Westill need some wm831x specific code and locking in place to check thatthe user key is handled correctly but only on the write side, reads arenot affected by the key.Signed-off-by: Mark Brown Acked-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

78bb3688 - mfd: Support multiple active WM831x AUXADC conversions

Tue, 07 Jun 2011 10:47:28 +0000

mfd: Support multiple active WM831x AUXADC conversionsThe WM831x AUXADC hardware can schedule multiple conversions at once,allowing higher performance when more than one source is in use as wecan have the hardware start new conversions without having to wait fora register write.Take advantage of this in the interrupt driven case, maintaining a list ofcallers that are waiting for AUXADC conversions and completing them allsimultaneously. The external interface of the AUXADC is not changed sothere will be limited use of the feature immediately.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

c1a82780 - mfd: Read wm831x AUXADC conversion results before acknowledging interrupt

Thu, 02 Jun 2011 18:18:52 +0000

mfd: Read wm831x AUXADC conversion results before acknowledging interruptEnsure that there's no possibility of loosing an AUXADC interrupt by readingthe conversion result in the IRQ handler when using interrupts. Otherwiseit's possible that under very heavy load a new conversion could be initiatedbefore the acknowledgement for a previous interrupt has happened.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

Thu, 02 Jun 2011 18:18:47 +0000

mfd: Fix bus lock interaction for WM831x IRQ set_type() operationThe WM831x IRQ set_type() operation is doing a direct register write whencalled but since set_type() is called with the bus lock held this isn'tlegal and could cause deadlocks in the IRQ core.Fix this by posting the updates into an array and syncing in thebus_sync_unlock() callback.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

mfd: Factor out WM831x I2C I/O from the core driverIn preparation for the addition of SPI support for the WM831x move the I2Cspecific code into a separate file with a separate Kconfig option so theI2C support can be excluded from the build.Also update the 1133-EV1 PMIC module support for SMDK6410 to use the newsymbol.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

b03b4d7c - mfd: Ensure WM831x charger interrupts are acknowledged when suspending

Thu, 08 Apr 2010 08:02:39 +0000

mfd: Ensure WM831x charger interrupts are acknowledged when suspendingThe charger interrupts on the WM831x are unconditionally a wake sourcefor the system. If the power driver is not able to monitor them (forexample, due to the IRQ line not having been wired up on the system)then any charger interrupt will prevent the system suspending for anymeaningful amount of time since nothing will ack them.Avoid this issue by manually acknowledging these interrupts when wesuspend the WM831x core device if they are masked. If software isactually using the interrupts then they will be unmasked and thischange will have no effect.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h

473fe736 - mfd: Use completion interrupt for WM831x AUXADC

Tue, 23 Feb 2010 11:08:06 +0000

mfd: Use completion interrupt for WM831x AUXADCUse the completion interrupt generated by the device rather thanpolling for conversions to complete. As a backup we still checkthe status of the AUXADC if we don't get a completion, mostly forsystems that don't have the WM831x interrupt infrastructure hookedup.Also reduce the timeout for completion of conversions to 5ms fromthe previous 10ms, the lower timeout should be sufficient.Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/wm831x/core.h
