Merge tag 'tegra-for-4.9-bus' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers

Pull "bus: NVIDIA Tegra ACONNECT changes for v4.9-rc1" from Thierry Reding:

This contains a patch that makes use of some symbols that were added in
v4.8 and a second patch takes advantage to enable building the driver as
a loadable module.

* tag 'tegra-for-4.9-bus' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  bus: tegra-aconnect: Use of_pm_clk_add_clk()
  bus: tegra-aconnect: Make symbol tristate
