* regulator: Add WM8350 regulator supportMark Brown2008-10-136-0/+1494
| | | | | | | | | | | | 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.

* mfd: Add WM8350 interrupt supportMark Brown2008-10-133-6/+787
| | | | | | | | | | | | | | | | 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.

* mfd: Add initialisation callback for WM8350Mark Brown2008-10-133-3/+25
| | | | | | | | | | | | 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.

* mfd: Add GPIO pin configuration support for WM8350Mark Brown2008-10-133-1/+233
| | | | | | | | | | | | | | | | | | | 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.

* mfd: Core support for the WM8350 AudioPlus PMICMark Brown2008-10-135-0/+2409
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | The WM8400 provides two programmable DCDC step-down (buck) convertors and four low-dropout (LDO) regulators.

* regulator: core - Rework machine API to remove string based functions.Liam Girdwood2008-10-136-330/+334
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This improves the machine level API in order to configure regulator constraints and consumers as platform data and removes the old string based API that required several calls to set up each regulator. The intention is to create a struct regulator_init_data, populate it's fields with constraints, consumers devices, etc and then register the regulator device from board.c in the standard Linux way. e.g. regulator LDO2 (supplying codec and sim) platform data. /* regulator LDO2 consumer devices */ static struct regulator_consumer_supply ldo2_consumers[] = { { .dev = &platform_audio_device.dev, .supply = "codec_avdd", }, { .dev = &platform_sim_device.dev, .supply = "sim_vcc", } }; /* regulator LDO2 constraints */ static struct regulator_init_data ldo2_data = { .constraints = { .min_uV = 3300000, .max_uV = 3300000, .valid_modes_mask = REGULATOR_MODE_NORMAL, .apply_uV = 1, }, .num_consumer_supplies = ARRAY_SIZE(ldo2_consumers), .consumer_supplies = ldo2_consumers, }; /* machine regulator devices with thier consumers and constraints */ static struct platform_device wm8350_regulator_devices[] = { { .name = "wm8350-regulator", .id = WM8350_LDO_2, .dev = { .platform_data = &ldo2_data, }, }, }; Changes in detail:- o Removed all const char* regulator config functions in machine API. o Created new struct regulator_init_data to contain regulator machine configuration constraints and consmuers. o Changed set_supply(), set_machine_constraints(), set_consumer_device_supply() to remove their string identifier parameters. Also made them static and moved functions nearer top of core.c. o Removed no longer used inline func to_rdev() o Added regulator_get_init_drvdata() to retrieve init data. o Added struct device* as parameter to regulator_register(). o Changed my email address.

* vfs: Use const for kernel parser tableSteven Whitehouse2008-10-1338-43/+43
| | | | | | | | | | | | | | This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.
