X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f780a7229363b4a4f771082692a0f946e9edcacd;p=thirdparty%2Fopenwrt.git

x86: modules: add packages for Intel LPSS drivers

Add driver packages for Intel Low-Power Subsystem devices which are part
of some Intel chipsets. They are mainly needed to have access to the I2C
bus used for HID devices.
