R-Car Sound needs to enable "ADG" on RMSTPCR9/SMSTPCR9 bit 22 to use
clk_i which came from the internal S0D4 or ZA2 clock.

According to the R-Car Series, 3rd Generation Hardware User’s Manual
Rev. 2.30, the parent clock of the Video Input Module (VIN) on R-Car D3
is S3D1. Update the driver to match the documentation.
This has no functional impact, as both S1D2 and S3D1 have the same clock
rate, and are always-on clocks.

The RPC and RPCD2 core clocks were added to the sections for internal
core clocks, while they are core clock outputs, visible from DT.
Move them to the correct sections.
Rename the ".rpc" clock on R-Car S4 to "rpc".
Fixup nearby whitespace to increase uniformity.

Describe the various clocks used by the SPI Multi I/O Bus Controller
(RPC-IF) on the R-Car D3 SoC: RPCSRC internal clock, RPC{,D2} clocks
derived from it, and RPC-IF module clock.
The RPCSRC clock divider on R-Car D3 is very similar to the one on R-Car
E3, but uses a different pre-divider for the PLL0 parent. Add a new
macro to describe it, reusing the existing clock type for R-Car E3.

Add clocks for MLP modules on Renesas R-Car E3 and D3 SoCs.
Similar to other R-Car Gen3 SoC, exact information on the parents of MLP
clocks on E3 and D3 is not available. However, since the parents of
these clocks are not anyhow software-controllable, the only harm from
this is inexact information exported via debugfs. So just keep the
parent set in the same way as with other Gen3 SoCs.

R-Car D3 ZA2 clock is from PLL0D3 or S0,
and it can be controlled by ZA2CKCR.
It is needed for R-Car Sound, but is not used so far.
Using default settings is very enough at this point.
This patch adds it by DEF_FIXED().

Add the CryptoCell module clocks and their parents for the CryptoCell
instances in the various Renesas R-Car Gen3 SoCs that do not have
support for them yet in their clock drivers (M3-W/W+, M3-N, E3, D3).

The clock sources of the AXI-bus clock (266.66 MHz) used for Audio-DMAC
DMA transfers are:
Channel R-Car H3 R-Car M3-W R-Car M3-N R-Car E3
---------------------------------------------------------------
Audio-DMAC0 S1D2 S1D2 S1D2 S1D2
Audio-DMAC1 S1D2 S1D2 S1D2 -
As a result, change the parent clocks of the Audio-DMAC{0,1} module
clocks on R-Car H3, R-Car M3-W, and R-Car M3-N to S1D2, and change the
parent clock of the Audio-DMAC0 module on R-Car E3 to S1D2.
NOTE: This information will be reflected in a future revision of the
R-Car Gen3 Hardware Manual.

The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Dec 22, 2017, and
Feb 28, 2018) removed the SSPSRC, SSP1, and SSP2 clocks on R-Car D3, as
this SoC does not have a Stream and Security Processor.
As these definitions were never used, they can just be removed.
The freed slots in the DT bindings header must not be reused, though.

According to R-Car Gen3 Hardware Manual Rev.1.00, R-Car D3 has the
RCLK Frequency Control Register (RCKCR), which determines the OSC and
RINT predivider values, and selection of the RCLK clock source between
RINT and the On-Chip Oscillator.
Hence change the OSC and RINT clock definitions to use the RCKCR
divider, and add the missing On-Chip Oscillator and RCLK clock source
switching logic.
