iio: adc: Add TI ADS1015 ADC driver support

The driver has sysfs readings with runtime PM support for power saving.
It also offers buffer support that can be used together with IIO software
triggers.

Datasheet can be found here:

iio: Add IIO support for the DAC on the Apex Embedded Systems STX104

The Apex Embedded Systems STX104 is a 16-channel 16-bit analog input and
2-channel 16-bit analog output PC/104 card. The STX104 incorporates a
large one mega-sample FIFO.

This driver provides IIO support for the 2-channel DAC on the STX104.
The base port addresses for the devices may be configured via the "base"
module parameter array.

The AD5625/AD5645/AD5665 are a family of 4 channel DACs with 12-bit, 14-bit
and 16-bit precision respectively. The devices come in 3 flavors in terms
of built-in reference, either no built-in reference, built-in 1.25V
reference or built-in 2.5V reference.

The AD5627/AD5647/AD5667 are similar to the AD5625/AD5645/AD5665 except
that they have 2 instead of 4 channels.

While these new devices are mostly register map compatible with the
existing devices support by the driver some offsets and register addresses
have been shuffled around. To accommodate this introduce a new register map
layout. For the lack of a better name we will just call it version 2.

This patch makes minor structural changes to support specifics
for LTC2617 DAC. This DAC requires different handling of the
power down modes. The configuration to actually support the
DAC will be submitted in a secondary patch.

Adjust the DECLARE_AD5064_CHANNELS() macro to accept a new
ext_info parameter. This allows to use different power down
modes per DAC. (e.g. DAC only support 90kohm to ground)

Add the chip_info parameter "powerdown_ltc". This parameter is
used in the ad5064_sync_powerdown_mode() function to handle the
power down command for LTC diffently. For those devices the
power down command must be addressed to the channel.

staging: wilc1000: change_virtual_intf: change codes for unified firmware

In previous patch, we use unified firmware on wilc, which means we do not need
to download firmware again to change virtual interfaces.
There are a lot of codes to change interface and they are needless now, so
remove them except wilc_set_operation_mode function which change the mode and
wilc_set_power_mgmt which control power save.
There will be unused functions and they will be removed in later patch.

staging: wilc1000: set bssid with mode

This patch add new argument mode to wilc_wlan_set_bssid and define mode in
struct wilc_vif also. The mode is used by get_if_handler function to get proper
netdevice for each mode.
The get_if_handler is changed together. Remove invalid handle codes and
add mode condition to get netdevice for the mode.

staging: wilc1000: remove wilc_set_machw_change_vir_if

wilc_set_machw_change_vir_if is not used anymore since we use one unified

let the wilc use the proper firmware. Remove wilc_set_machw_change_vir_if
and it's functions calls.
In the later patch, mac index will be passed to wilc device.

Building wilc1000 with clang currently fails in the staging-next branch:

drivers/staging/wilc1000/wilc_spi.c:123:34: warning: tentative definition of variable with internal linkage has incomplete non-array type 'const struct wilc1000_ops' [-Wtentative-definition-incomplete-type]
static const struct wilc1000_ops wilc1000_spi_ops;

The reason is that wilc1000_ops was left behind after a recent cleanup,
and is completely unused and also uninitialized and const and has an
incomplete type.

Removing the variable is obviously correct, and gets rid of the warning.
