Currently these PMC clocks are registered by Tegra clock driver using clk_register_mux and clk_register_gate by passing PMC base address and register offsets and PMC programming for these clocks happens through direct PMC access by the clock driver. With this, when PMC is in secure mode any direct PMC access from the non-secure world does not go through and these clocks will not be functional. This patch adds these clocks registration with PMC as a clock provider for these clocks. clk_ops callback implementations for these clocks uses tegra_pmc_readl and tegra_pmc_writel which supports PMC programming in secure mode and non-secure mode.

Blink pad DPD state and enable controls are part of Tegra PMC register space. Currently Tegra clock driver registers blink control by passing PMC address and register offset to clk_register_gate which performs direct PMC access during clk_ops and with this when PMC is in secure mode, any access from non-secure world does not go through. This patch adds blink control registration to the Tegra PMC driver using PMC specific clock gate operations that use tegra_pmc_readl and tegra_pmc_writel to support both secure mode and non-secure mode PMC register access.

Any direct PMC register access from non-secure world will not go through and all the PMC clocks and blink control are done in Tegra PMC driver with PMC as clock provider. This patch removes tegra_pmc_clk_init along with corresponding clk ids from Tegra clock driver.

Actual audio mclk is clk_out_1 and to use PLLA for mclk rate control, need to clk_out_1_mux parent to extern1 and extern1 parent to PLLA_OUT0. Currently Tegra clock driver init sets the parents and enables both clk_out_1 and extern1 clocks. But these clocks parent and enables should be controlled by ASoC driver. Clock parents can be specified in device tree using assigned-clocks and assigned-clock-parents. To enable audio mclk, both clk_out_1 and extern1 clocks need to be enabled. This patch configures parents for clk_out_1 and extern1 clocks if device tree does not specify clock parents inorder to support old device tree and controls mclk using both clk_out_1 and extern1 clocks.

New device tree uses clk_out_1 from pmc clock provider. So, this patch adds fallback to extern1 in case of retrieving mclk fails to be backward compatible of new device tree with older kernels.

So, this patch removes parenting and enabling extern1 from clock init of Tegra30 and above and removes enabling cdev1 from Tegra20 clock init.

These clocks are moved from clock driver to pmc driver with pmc as the clock provider for these clocks. This patch adds #clock-cells property with 1 clock specifier to the Tegra PMC node in device tree.
