clk: tegra: Update binding doc for Tegra132
Tegra132 has almost the same clock structure than Tegra124. This patch documents the missing clock IDs. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com> [paul@pwsan.com: updated binding documentation to reflect the recent split of Tegra124 clock IDs into a Tegra124/132-common file and a Tegra124-specific file] Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Paul Walmsley <pwalmsley@nvidia.com> Cc: Stephen Warren <swarren@wwwdotorg.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Alexandre Courbot <gnurou@gmail.com> Cc: Rob Herring <robh+dt@kernel.org> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: Kumar Gala <galak@codeaurora.org>
