mfd: max77686: Add Maxim 77802 PMIC support

2014-07-25T14:31:48+00:00

Maxim MAX77802 is a power management chip that contains 10 high
efficiency Buck regulators, 32 Low-dropout (LDO) regulators used
to power up application processors and peripherals, a 2-channel
32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface
to program the individual regulators, clocks outputs and the RTC.

This patch adds support for MAX77802 to the MAX77686 driver and is
based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.

mfd: max77686: Convert to use regmap_irq

2014-07-21T15:54:26+00:00

By using the generic IRQ support in the Register map API, it
is possible to get rid max77686-irq.c and simplify the code.

mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption

2014-07-09T13:58:12+00:00

This patch use regulator_suspend_prepare() function to prepare the proper state
of regulators for suspend state to remove un-necessary leakage power-consumption.

mfd: Fix cs5535 dependencies

2014-07-09T13:57:59+00:00

As far as I know, the CS5535 and CS5536 chipsets are companions of the
Geode series of processors, which are 32-bit only. So the CS5535
drivers are not needed on x86-64, except for build testing purpose.

This aligns the dependencies to what FB_GEODE already uses.

mfd: timberdale: Depend on X86_32

2014-07-09T13:57:59+00:00

As far as I know the Timberdale chip was only used as a companion for
Intel Atom E600 series processors. As such, its drivers are only
useful on X86_32.

mfd: davinci: Voicecodec needs regmap_mmio

2014-06-26T12:33:58+00:00

Without REGMAP_MMIO, building that driver results in a link error:

drivers/built-in.o: In function `davinci_vc_probe':
:(.init.text+0x3c1c): undefined reference to `devm_regmap_init_mmio_clk'

This adds a Kconfig 'select' statement as the usual way to ensure
that REGMAP_MMIO is enabled.

mfd: STw481x: Allow modular build

2014-06-26T12:33:50+00:00

This driver depends on I2C, which may be a loadable module.
While you'd probably want both to be built-in in practice,
allowing a modular build avoids possible randconfig link
errors.

mfd: UCB1x00: Enable modular build

2014-06-26T12:33:34+00:00

The UCB1200 / UCB1300 driver uses the MCP_SA11X0 driver, which
can be a loadable module, but this results in a link error
when UCB1200 itself is built-in:

drivers/built-in.o: In function `ucb1x00_io_set_dir':
:(.text+0x4a364): undefined reference to `mcp_reg_write'
drivers/built-in.o: In function `ucb1x00_io_write':
:(.text+0x4a3dc): undefined reference to `mcp_reg_write'
drivers/built-in.o: In function `ucb1x00_io_read':
:(.text+0x4a400): undefined reference to `mcp_reg_read'
drivers/built-in.o: In function `ucb1x00_adc_enable':
:(.text+0x4a460): undefined reference to `mcp_enable'
...

This can easily be resolved by making CONFIG_MCP_UCB1200 itself
a tristate option, since that causes Kconfig to track the
dependency correctly.
