[linux-yocto] [yocto-kernel-cache][PATCH] netfilter: enable connection tracking for IPv6

2016-12-12 Thread Dmitry Rozhkov 
In case of the DROP policy in the INPUT chain a host using IPv6 still
might need to receive TCP packets for established connections, that is
to have the rule

-A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT

in its INPUT chain of ip6tables. For this feature to work the option
CONFIG_NF_CONNTRACK_IPV6 needs to be enabled.

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.

2016-12-12 Thread tuomas . katila 
From: Tuomas Katila 

Patches are intended for the bxt-rebase branch

Backported ti-ads1015 support from linux-yocto 4.8 kernel. The
chip is supported in some Joule extender boards, such as Gravity
Expansion Shield for Intel Joule SKU: DFR0465.

Also added ACPI support for the driver.

  iio: adc: Add TI ADS1015 ADC driver support

Matt Ranostay (3):
  iio: adc: ti-ads1015: add support for ADS1115 part
  iio: adc: ti-ads1015: add datasheet names
  iio: adc: ti-ads1015: add indio_dev->dev.of_node reference
