  clk: tegra: Remove audio clocks configuration from clock driver (2020-03-12 12:10:49 +0100)

Thanks,
Thierry

----------------------------------------------------------------
clk: tegra: Changes for v5.7-rc1

These changes remove PMC clocks from the clock and reset controller
driver because they are controlled by bits in the PMC controller.

      dt-bindings: clock: tegra: Add IDs for OSC clocks
      dt-bindings: tegra: Convert Tegra PMC bindings to YAML
      dt-bindings: soc: tegra-pmc: Add Tegra PMC clock bindings
      dt-bindings: soc: tegra-pmc: Add ID for Tegra PMC 32 kHz blink clock
      clk: tegra: Add support for OSC_DIV fixed clocks
      clk: tegra: Add Tegra OSC to clock lookup
      clk: tegra: Fix Tegra PMC clock out parents

Hello Thierry,

Since the audio-clk patches haven't been updated and applied, now there
are warnings in the kernel log. Please work with Sowjanya to fix it in
5.7, thanks in advance.
