[PATCH v1 0/2] clk: tegra114: Add CSI pad clock gates

[Svyatoslav Ryhel]

Tegra114 has CSI pad bits in both PLLD and PLLD2 clocks that are required
for the correct work of the CSI block. Add CSI pad A and pad B clock gates
with PLLD/PLLD2 parents, respectively.

This change is similar to Tegra30 pad clocks and is required for CSI block.

[PATCH v1 1/2] dt-bindings: clock: tegra114: Add IDs for CSI pad clocks

[Svyatoslav Ryhel]

Tegra114 has CSI pad clock enable bits embedded into PLLD/PLLD2 registers.
Add ids for these clocks. Additionally, move TEGRA114_CLK_CLK_MAX into
clk-tegra114 source.
