6745ca5d95 clk: renesas: r9a09g077: Add LCDC and PLL3 clock support for RZ/T2H display pipeline
Add the clock definitions and PLL logic required to supply the LCDC
(VSPD/FCPVD/DU) blocks on the RZ/T2H (R9A09G077) SoC. The RZ/T2H display
subsystem depends on a dedicated PLL (PLL3) and a set of new derived
clocks.

Introduce a new PLL clock type and implement rate recalculation,
programming and locking sequences for PLL3 using the RZ/T2H specific
divider and VCO limits. Add the corresponding muxes and divider entries,
expose the LCDC core clock, and register the LCDC module clock using the
correct PCLK parent.

This enables the RZ/T2H clock driver to generate the display pipeline
clocking tree needed by the DU and VSP-based composition engines, allowing
upcoming display support to be integrated without duplicating CPG logic.

73c360100d clk: renesas: rzv2h-cpg: Extract PLL calculation helpers into shared library
Move the RZ/V2H PLL and divider parameter calculation helpers from
rzv2h-cpg.c into a new reusable library.

Introduce the CLK_RZV2H_CPG_LIB Kconfig symbol and add
rzv2h-cpg-lib.c to host the PLL parameter search algorithms currently
implemented by rzv2h_get_pll_pars() and rzv2h_get_pll_divs_pars().
Export the helpers as rzv2h_cpg_get_pll_pars() and
rzv2h_cpg_get_pll_divs_pars() for use by other drivers.

Update the public clock header to expose the new interfaces and provide
compatibility aliases for the existing helper names, avoiding build
breakage for current users while allowing future conversions to the new
API.

This prepares for reuse of the PLL and divider calculation logic by
other Renesas clock drivers, including upcoming RZ/T2H and RZ/N2H CPG
support, without duplicating the implementation.

4f4230ff5d clk: renesas: rzv2h-cpg: Use per-SoC PLL reference frequency for calculations
Introduce a per-SoC PLL reference input frequency parameter to avoid
relying on a hardcoded 24MHz constant during PLL configuration math.

Add an input_fref member to struct rzv2h_pll_limits. In the core
calculation helper rzv2h_get_pll_pars(), derive the base input clock
rate from limits->input_fref, utilizing the conditional ternary operator
to fall back to 24MHz if the struct field is left uninitialized (0),
and drop the obsolete macro RZ_V2H_OSC_CLK_IN_MEGA.

This abstraction permits the reuse of the common PLL divider logic on
newer SoC platforms like the RZ/T2H, which feature a 48 MHz PLL reference
clock input instead of the 24 MHz signal used by RZ/V2H(P), without
disrupting existing platforms.

0a6643b1a5 clk: renesas: cpg-mssr: Implement dedicated MSTP delay logic for RZ/T2H LCDC and RTC
Introduce a dedicated clock delay mechanism, cpg_rzt2h_mstp_delay(), to
satisfy the module-stop (MSTP) state release requirements specified in
the RZ/T2H hardware manual.

Per the hardware manual, while a standard 10 us delay (satisfying 7 dummy
reads) is sufficient for most IP blocks, the LCDC requires 100 dummy reads
(142 us) and the RTC requires 300 dummy reads (428 us) to stabilize after
being released from a module-stop state.

Implement a conditional bitmask filter helper that switches wait
intervals based on the packaged module clock index. In
cpg_mstp_clock_endisable(), the clock index and individual target bits are
known, allowing an exact match. In the resume path cpg_mssr_resume_noirq(),
where individual bits are not tracked, pass a fallback register index base
(`reg * 32`) with bit verification masked out to match on the peripheral's
register group block instead.

7774d5b240 clk: renesas: r9a09g047: Add audio clock and reset support
Add clock and reset entries for audio-related modules on the RZ/G3E SoC.

Target modules are:
 - SSIU (Serial Sound Interface Unit) with SSI ch0-ch9,
 - SCU (Sampling Rate Converter Unit) with SRC ch0-ch9, DVC ch0-ch1,
   CTU/MIX ch0-ch1,
 - DMACpp (Audio DMA Controller),
 - ADG (Audio Clock Generator) with divider input clocks and audio
   master clock outputs.

The ADG SSI clock outputs (adg_ssi[0-9]_clk) are parented on
CLK_PLLCLN_DIV8 as a deliberate simplification: the ADG dynamically
muxes each output between adg_0_clk_195m and audio_clk[a,b,c] at
runtime via ADG_AUDIO_CLK_SEL{0,1,2}, owned by the rsnd-adg driver.

While at it, reorder plldty_div16 to group it with the other plldty

these macros are not RZG3L-specific and are shared across SoCs.

Also fold CPG_PLL_MON_OFFSET() into rzg2l-cpg.c alongside the other
CPG_PLL_*_OFFSET() helpers introduced in previous patches.

2e3974747e clk: renesas: rzg3s/rzg3l: Simplify PLL configuration macro
Replace the per-SoC G3S_PLL146_CONF() and G3L_PLL1467_CONF() macros with
a unified CPG_PLL_CONF(stby, setting) macro defined in rzg2l-cpg.h.

Drop the now-redundant GET_REG_SAMPLL_{CLK1, SETTING}() macros, replacing
the latter with CPG_PLL1_SETTING_OFFSET() using FIELD_GET() to extract the
offset value. Update RZG3L_PLL_{STBY,MON}_OFFSET() macros to derive
offsets directly from CPG_PLL_STBY_OFFSET().

6549ef9cc2 clk: renesas: rzg2l: Simplify SAM PLL configuration macro
Replace the PLL146_CONF() macro and its associated CPG_SAMPLL_CLK{1,2}(n)
helpers with a single CPG_SAM_PLL_CONF(stby) macro that takes the PLL
standby register offset directly.

This removes the implicit coupling between PLL index n and register layout
and eliminates the now-redundant GET_REG_SAMPLL_CLK2() macro. The RZ/V2M
PLL4 definition is also updated to use the new macro with its explicit
standby offset (0x100), removing the local PLL4_CONF define.

No functional changes.

Extend the determine_rate callback to calculate and propagate PLL
parameters via rzv2h_get_pll_dtable_pars() when LVDS output is selected,
using a new helper function rzv2h_cpg_plldsi_smux_lvds_determine_rate().

The CLK_SMUX2_DSI{0,1}_CLK clock multiplexers select between two paths
with different duty cycles:

- CDIV7_DSIx_CLK (LVDS path, parent index 0): asymmetric H/L=4/3 duty (4/7)
- CSDIV_DSIx (DSI/RGB path, parent index 1): symmetric 50% duty (1/2)

Implement rzv2h_cpg_plldsi_smux_{get,set}_duty_cycle clock operations to
allow the DRM driver to query and configure the appropriate clock path
based on the required output duty cycle.
