Subject: mvebu: enable PCA955x driver for clearfog to enable pcie and usb
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c4f4d65835edc2631e10524e078d73f675e00dca;p=openwrt%2Fstaging%2Fblocktrron.git

mvebu: enable PCA955x driver for clearfog to enable pcie and usb

Some of the PCIe and USB signals use a GPIO expander on I2C on ClearFog,
so enable the driver so that they can be configured to their required
values.
