Switched Tegra210 PLLRE registration to common PLL ops instead of special PLLRE ops used on previous Tegra chips. The latter ops do not follow chip specific PLL frequency table, and do not apply chip specific rate calculation method. Removed unnecessary default rate setting that duplicates h/w reset state, and is overwritten by clock initialization, anyway. Signed-off-by:

Remove from Tegra210 PLLSS registration code sections that - attempt to set PLL minimum rate (unnecessary, and dangerous if PLL is already enabled on boot) - apply pre-Tegra210 defaults settings - check IDDQ setting (duplicated with Tegra210 PLLSS check defaults) Replaced setting of reference clock with check that default oscillator selection is not changed, and failed registration otherwise as validation was only done with the oscillator as the reference clock. Reordered registration, so that PLL initialization is called after VCOmin adjustment. Signed-off-by:

Tegra210 PLLX uses the same sequences than then PLLC instances. So there is no need to have a special registration function and ops struct for it. Simplify the code by changing all references to the Tegra210 PLLX registration function to the Tegra210 PLLC registration function and avoid duplicate functionality.

The clock bimc_gpu_clk_src is incorrectly set to use the shared rcg2 ops, which are for RCGs with child branches controlled by different CPUs. The result of the incorrect ops is that the GPU's PM runtime may leave this clock set at a very low rate. Fix this issue by using the correct rcg2 ops.

On R-Car Gen3 SoCs with a Spread Spectrum Clock Generator (e.g. R-Car D3), a peripheral clock divider has been added, to select between clean and spread spectrum parents. Add a new clock type to the R-Car Gen3 driver core to handle this. To avoid increasing the size of struct cpg_core_clk, both parents and dividers are stored in the existing parent resp. div fields.

On some R-Car Gen3 SoCs (e.g. R-Car D3), PLL1 and PLL3 use a divider value different from one. Extend struct rcar_gen3_cpg_pll_config to handle this. As all multipliers and dividers are small, table size increase can be kept limited by storing them in u8s instead of unsigned ints, which saves ca. 0.5 KiB for a generic kernel. Signed-off-by:

The CLK_SET_RATE_PARENT flag is added to clocks between the EPLL and the audio subsystem clock controller so that the EPLL's output frequency can be set indirectly with clk_set_rate() on a leaf clock. That should be safe as EPLL is normally only used to generate clock for the audio subsystem. With this change we can avoid passing the EPLL clock to the ASoC machine driver.

This allows clk rate propagation up to the clock tree so EPLL can be reprogrammed indirectly when setting rate of the Audio Subsystem clocks. The advantage is that sound machine driver can operate only on the leaf clocks rather than explicitly re-configuring the root clock (EPLL). Signed-off-by:
