* mfd: Constify static struct resourcesRikard Falkeborn2020-11-191-1/+1
| | | | | | | | | | 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.

* mfd: tps65090: Make it explicitly non-modularPaul Gortmaker2019-02-011-25/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_TPS65090 drivers/mfd/Kconfig: bool "TI TPS65090 Power Management chips" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

| | | | | | | | | | | | | | Regmap config max_register field should contain number of device last register, however num_reg_defaults_raw field should be set to register count instead (usually one register more than max_register). tps65090 driver had both of these fields set to the same value, fix this by introducing separate defines for max register number and total count of registers.

In order to avoid adding more duplicate #defines, we also move some register offset definitions to the mfd driver (and resolve inconsistent names).

| | | | | | | | | | | | If we weren't given an interrupt we shouldn't tell child devices (like the tps65090 charger) that they have an interrupt. This is needed so that we can support polling mode in the tps65090 charger driver. See also (charger: tps65090: Allow charger module to be used when no irq).

We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.

* mfd: core: Push irqdomain mapping out into devicesMark Brown2012-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.
