Merge tag 'tegra-for-5.5-clk-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into clk-tegra

Pull Tegra clk driver updates from Thierry Reding:

The bulk of these changes implement suspend/resume support for Tegra210.
In addition, some of the SOR clocks on earlier Tegra generations are
reimplemented to more closely match the implementation on later chips,
which in turn makes it possible to handle HDMI and DP support in a more
unified way.
