MFD_ARIZONA_I2C and MFD_ARIZONA_SPI both select MFD_ARIZONA and all
three of those select MFD_CORE, this makes the selects of MFD_CORE in
MFD_ARIZONA_I2C and MFD_ARIZONA_SPI redundant, so we remove them.Signed-off-by: Charles Keepax

The prcmu_config_clkout() function ensures that the 'clkout' argument
can only be '0' or '1' using an appropriate BUG_ON(), so the compiler
should know that the div_mask, mask, and bits variables are always
initialized later on. However, it doesn't understand this in gcc-5.2
and produces a false positive warning instead:drivers/mfd/db8500-prcmu.c: In function 'prcmu_config_clkout':
drivers/mfd/db8500-prcmu.c:762:10: error: 'div_mask' may be used uninitialized in this function [-Werror=maybe-uninitialized]

^
drivers/mfd/db8500-prcmu.c:757:7: error: 'bits' may be used uninitialized in this function [-Werror=maybe-uninitialized]Replacing the switch() statement with an equivalent if() lets

tps65010 driver's initcall cannot succeed when the driver is built-in,
because it expects that the I2C probe is completed at initcall time;
this cannot happen as MFD is initialized before I2C. Also on systems
where the chip is not present there is unnecessary 30 ms delay during
the boot.Instead of waiting for probe to finish, just register the I2C device.
If some boards need retry mechanism for startup glitches, that should be
done in the actual probe function. Also delete the driver banner message.The patch allows to use tps65010 again with OMAP1 (where it's required
to be built-in) and enables e.g. USB and LED functionality on OMAP5912 OSK.Signed-off-by: Aaro Koskinen

include/asm-generic/div64.h:207:28: warning: comparison of distinct pointer types lacks a cast

This fixes some leftover code style issues in the axp20x core.
Signed-off-by: Chen-Yu Tsai
Signed-off-by: Lee Jones -
The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.Whitespace and other style errors in the moved i2c specific code
have been fixed. Included but unused header files are removed as
well.Signed-off-by: Chen-Yu Tsai

In axp20x_match_device(), match the of_device_id table bound to the
device driver instead of pointing to axp20x_of_match directly. This
will allow us to keep axp20x_match_device() unmodified when we expand
the axp20x driver into multiple ones covering different interface
types.of_device_get_match_data() cannot be used here as we need to know if
it failed to get a match, or if the match data value just happened to
be 0, as it is for the AXP152.Signed-off-by: Chen-Yu Tsai
Signed-off-by: Lee Jones -
The first argument passed to axp20x_match_device(), struct axp20x_dev *,
already contains a pointer to the device. By rearranging some code,
moving the assignment of the pointer before axp20x_match_device() is
called, we can eliminate the second parameter.Suggested-by: Andy Shevchenko

This is a driver for the imx25 ADC/TSC module. It controls the
touchscreen conversion queue and creates a touchscreen input device.
The driver currently only supports 4 wire touchscreens. The driver uses
a simple conversion queue of precharge, touch detection, X measurement,
Y measurement, precharge and another touch detection.This driver uses the regmap from the parent to setup some touch specific
settings in the core driver and setup a idle configuration with touch
detection.Signed-off-by: Markus Pargmann

This is a conversion queue driver for the mx25 SoC. It uses the central
ADC which is used by two seperate independent queues. This driver
prepares different conversion configurations for each possible input.
For a conversion it creates a conversionqueue of one item with the
correct configuration for the chosen channel. It then executes the queue
once and disables the conversion queue afterwards.The reference voltages are configurable through devicetree subnodes,
depending on the connections of the ADC inputs.Signed-off-by: Markus Pargmann

This is the core driver for imx25 touchscreen/adc driver. The module
has one shared ADC and two different conversion queues which use the
ADC. The two queues are identical. Both can be used for general purpose
ADC but one is meant to be used for touchscreens.This driver is the core which manages the central components and
registers of the TSC/ADC unit. It manages the IRQs and forwards them to
the correct components.Signed-off-by: Markus Pargmann

Convert this driver to use clkdev_create() instead of
clk_register_clkdevs(). The latter API is only used by this driver,
although this driver only allocates one clk to add anyway.
Furthermore, this driver allocates the clk_lookup structure with
devm, but clkdev_drop() will free that structure when passed,
leading to a double free when this driver is removed. Clean it
all up and pave the way for the removal of clk_register_clkdevs().Cc: Andy Shevchenko
