cover WM8350 support

These patches against the regulator tree add initial support for the WM8350, a multi-function device with several subsystems targetted at embedded systems. This series adds a core driver providing device acess under drivers/mfd and support for the PMIC functionality of the device via the regulator API. Due to their use in the core some definitions for other parts of the device are also included - drivers for these will follow.

All the WM8350 drivers submitted here were originally written by Liam Girdwood with some updates from me for submission to mainline.

Samuel, as with the WM8400 are you OK with merging this via the regulator tree?

The following changes since commit fcbd54dd718e6741b05f8e5b08cbc75548acf0e4:

PATCH 11/13 mfd: Add initialisation callback for WM8350

In reply to Mark Brown

Some functions of the WM8350 require board-specific initialisation on startup. Provide a callback to the WM8350 driver in platform data for platforms to use to configure the chip. Use of a callback allows platforms to control the ordering of initialisation which can be important.

PATCH 10/13 mfd: Add GPIO pin configuration support for WM8350

The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions.

This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so.

This code was all written by Liam Girdwood and has had minor updates and rearrangements by Mark Brown.

PATCH 12/13 mfd: Add WM8350 interrupt support

In reply to Mark Brown

The WM8350 has an interrupt line to the CPU which is shared by the devices on the CPU. This patch adds support for the interrupt controller within the WM8350 which identifies which identifies the interrupt cause. In common with other similar chips this is done outside the standard interrupt framework due to the need to access the interrupt controller over an interrupt-driven bus.

This code was all originally written by Liam Girdwood with updates for submission by me.

PATCH 13/13 regulator: Add WM8350 regulator support

The WM8350 features six DCDC convertors (four buck and two boost), four LDO voltage regulators and two constant current sinks. This driver adds support for these through the regulator API.

This driver was written by Liam Girdwood with updates for submission from Mark Brown.

PATCH 8/13 mfd: Core support for the WM8350 AudioPlus PMIC

In reply to Mark Brown

The WM8350 is an integrated audio and power management subsystem intended for use as the primary PMIC in mobile multimedia applications. The WM8350 can be controlled via either I2C or SPI - the control interface is provided by a separate module in order to allow greatest flexibility in configuring the kernel.

This driver was originally written by Liam Girdwood and has since been updated to current kernel APIs and split up for submission by me. All the heavy lifting here was done by Liam.

I would make the WM8350 mode configuration selectable by the target machines Kconfig rather than let the user choose. Wrong choices would probably mean broken hardware.

Shouldn't this be #elif for each mode ?

Ditto for the default register values. I would also #error if no mode was selected just to make it's correctly set by machine/board authors.

I would make the WM8350 mode configuration selectable by the target machines Kconfig rather than let the user choose. Wrong choices would probably mean broken hardware.

Machines can still select config modes - this just allows people to enable additional modes. That said, on reflection I can't actually see much use for that so I'll just hide the options from the user menus (patch below).

Ditto for the default register values.

This is a deliberate decision in order to allow people to build kernel images supporting multiple boards - the driver will check the mode with the hardware and error out at probe time if support for the mode isn't compiled in. If the register maps were smaller I'd just compile them all in.

was selected just to make it's correctly set by machine/board authors.

Yeah, that'd be nice but if the driver does that then it'll be harder for people like subsystem maintainers to do build tests with WM8350 drivers and they won't get picked up by things like allmodconfig checks.

The patch below adds a build time warning for this case - the runtime checks will mean that the driver should be safe since it won't run on unknown hardware.

These patches against the regulator tree add initial support for the WM8350, a multi-function device with several subsystems targetted at embedded systems. This series adds a core driver providing device acess under drivers/mfd and support for the PMIC functionality of the device via the regulator API. Due to their use in the core some definitions for other parts of the device are also included - drivers for these will follow.

Quoted 5 lines

All the WM8350 drivers submitted here were originally written by Liam Girdwood with some updates from me for submission to mainline.

Samuel, as with the WM8400 are you OK with merging this via the regulator tree?

Samuel, are fine to Ack the MFD parts ?

PATCH 10/14 mfd: Add GPIO pin configuration support for WM8350

In reply to Mark Brown

The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions.

This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so.

This code was all written by Liam Girdwood and has had minor updates and rearrangements by Mark Brown.

PATCH 11/14 mfd: Add initialisation callback for WM8350

In reply to Mark Brown

Some functions of the WM8350 require board-specific initialisation on startup. Provide a callback to the WM8350 driver in platform data for platforms to use to configure the chip. Use of a callback allows platforms to control the ordering of initialisation which can be important.

PATCH 14/14 mfd: Add WM8350 subdevice registration helper

In reply to Mark Brown

Most of the subdevices for the WM8350 code are registered in the same fashion so factor out the code to do the initial registration.

PATCH 13/14 regulator: Add WM8350 regulator support

In reply to Mark Brown

The WM8350 features six DCDC convertors (four buck and two boost), four LDO voltage regulators and two constant current sinks. This driver adds support for these through the regulator API.

This driver was written by Liam Girdwood with updates for submission from Mark Brown.

PATCH 12/14 mfd: Add WM8350 interrupt support

In reply to Mark Brown

The WM8350 has an interrupt line to the CPU which is shared by the devices on the CPU. This patch adds support for the interrupt controller within the WM8350 which identifies which identifies the interrupt cause. In common with other similar chips this is done outside the standard interrupt framework due to the need to access the interrupt controller over an interrupt-driven bus.

This code was all originally written by Liam Girdwood with updates for submission by me.

PATCH 8/14 mfd: Core support for the WM8350 AudioPlus PMIC

In reply to Mark Brown

The WM8350 is an integrated audio and power management subsystem intended for use as the primary PMIC in mobile multimedia applications. The WM8350 can be controlled via either I2C or SPI - the control interface is provided by a separate module in order to allow greatest flexibility in configuring the kernel.

This driver was originally written by Liam Girdwood and has since been updated to current kernel APIs and split up for submission by me. All the heavy lifting here was done by Liam.

Re: [PATCH 10/14] mfd: Add GPIO pin configuration support for WM8350

In reply to Mark Brown
Quoted 9 lines · Mark Brown

The WM8350 provides a number of user-configurable pins providing access to various signals generated by the functions on the chip. These are referred to as GPIO pins in the device documentation but in Linux terms they are more general than that, providing configuration of alternate functions.

This patch implements support for selecting the alternate functions for these pins. They can also be used as GPIOs in the normal Linux sense - a subsequent patch will add support for doing so.

I expect it to implement the giolib interface, right ?

Cheers,
Samuel.

Re: [PATCH 14/14] mfd: Add WM8350 subdevice registration helper

In reply to Mark Brown
Quoted 2 lines · Mark Brown

Most of the subdevices for the WM8350 code are registered in the same fashion so factor out the code to do the initial registration.

Out of curiosity (and also because I would like to start working on improving mfd-core), why didnt you consider using the mfd-core API ?

Cheers,
Samuel.

Sorry guys, but I havent had time to look at those patches yet. Liam, when would be the last moment for me to ACK/NACK them ? I expect to be able to do so during this weekend.

Quoted 5 lines

I've done some updates since the original posting incorporating feedback from Liam and an update for the regulator API - do you want me to repost with those? They're sitting in:

git://opensource.wolfsonmicro.com/linux-2.6-audioplus for-lrg

Yes please.

I'm fine with Mark's mfd patches going upstream via your tree. Please add an "Acked-by: Samuel Ortiz <[email protected]>" line to all the mfd patches (i.e. all of them except patch #13).

Thanks to Mark and you for those.

Cheers,

In reply to Samuel Ortiz

Most of the subdevices for the WM8350 code are registered in the same fashion so factor out the code to do the initial registration.

Out of curiosity (and also because I would like to start working on improving mfd-core), why didnt you consider using the mfd-core API ?

I did actually consider that - if it hadn't been so near the merge window it'd have got a bit more attention but I'd been going for a minimally invasive approach.

Originally the major issue was that the MFD API only worked for platform devices but that has now been resolved. Now the main issue for the WM8350 is that the MFD core API uses platform_device_add_resources() unconditionally but that fails if the device has no resources as will be the case for anything on the WM8350, at least until I integrate the
interrupt controller with the standard interrupt interface. The MFD
core does ignore the result of the call currently but it probably shouldn't and I didn't want to rely on it continuing to do so. The patch below ought to address that, though it's tested with my "Hey, look! It compiles!" test plan - if it looks sane to you I'll give it a test and repost with a proper changelog.

It's not an issue for the WM8350 but some devices with interrupt controllers may have issues since currently the MFD API wants to put all the interrupts within a per-device range but for some devices there will be interrupts exposed via separate IRQ lines (so you don't have to take the hit of working with an I2C/SPI interrupt controller) meaning that some of the interrupts for subdevices may be in different ranges. For the WM8350 this isn't such a problem since everything *can* go via the main interrupt controller and overrides can be provided via platform data (as they are at present, though the main interrupt controller doesn't use the standard API) but if use of a separate interrupt line were non-optional it'd be a problem.

There's also the issue of passing over the pointer to the shared device data for arbitration - you can use platform data but the MFD API wants to copy it so it's a bit fiddly. I'm thinking that the sensible thing may just be to have the child devices use the parent link in the device tree for this which is already fine with the MFD core.
