[PATCH v1 1/4] ARM: tegra: asus-tf101: Enable S/PDIF and HDMI audio

[Dmitry Osipenko]

Enable S/PDIF controller to enable HDMI audio support on ASUS TF101.
Use nvidia,fixed-parent-rate property that prevents audio rate conflict
between S/PDIF and I2S.

[PATCH v1 2/4] ARM: tegra: transformer: Drop reg-shift for Tegra HS UART

[Dmitry Osipenko]

From: Svyatoslav Ryhel <clamor95@gmail.com>

When the Tegra High-Speed UART is used instead of the regular UART, the
reg-shift property is implied from the compatible string and should not
be explicitly listed.

[PATCH v1 3/4] ARM: tegra: tf700t: Rename DSI node

[Dmitry Osipenko]

Rename DSI bridge node to match the requirement of the DSI DT schema.
This silences DTB-check warning about the incorrect name.
