2025-07-08clk: renesas: r9a08g045: Add MSTOP for coupled clocks as wellClaudiu Beznea
If MSTOP is not added for both clocks in a coupled pair, and the clocks are not disabled in the reverse order of their enable sequence, the MSTOP may remain enabled when disabling the clocks. This happens because rzg2l_mod_clock_endisable() executes for coupled clocks only when a single clock from the pair is enabled. If one clock has no MSTOP defined, it can result in the MSTOP configuration being left active when the clocks are disabled out of order (i.e., not in the reverse order of enabling).

2025-06-10clk: renesas: rzg2l: Add support for MSTOP in clock enable/disable APIClaudiu Beznea
The RZ/{G2L,V2L,G3S} CPG versions support a feature called MSTOP. Each module has one or more MSTOP bits associated with it, and these bits need to be configured along with the module clocks. Setting the MSTOP bits switches the module between normal and standby states. Previously, MSTOP support was abstracted through power domains (struct generic_pm_domain::{power_on, power_off} APIs). With this abstraction, the order of setting the MSTOP and CLKON bits was as follows: Previous Order: A/ Switching to Normal State (e.g., during probe): 1/ Clear module MSTOP bit 2/ Set module CLKON bit B/ Switching to Standby State (e.g., during remove): 1/ Clear CLKON bit 2/ Set MSTOP bit However, in some cases (when the clock is disabled through devres), the order may have been (due to the issue described in link section): 1/ Set MSTOP bit 2/ Clear CLKON bit Recently, the hardware team has suggested that the correct order to set the MSTOP and CLKON bits is: Updated Order: A/ Switching to Normal State (e.g., during probe): 1/ Set CLKON bit 2/ Clear MSTOP bit B/ Switching to Standby State (e.g., during remove): 1/ Set MSTOP bit 2/ Clear CLKON bit To prevent future issues due to incorrect ordering, the MSTOP setup has now been implemented in rzg2l_mod_clock_endisable(), ensuring compliance with the sequence suggested in Figure 41.5: Module Standby Mode Procedure from the RZ/G3S HW manual, Rev1.10. Additionally, since multiple clocks of a single module may be mapped to a single MSTOP bit, MSTOP setup is reference-counted. Furthermore, as all modules start in the normal state after reset, if the module clocks are disabled, the module state is switched to standby. This prevents keeping the module in an invalid state, as recommended by the hardware team.

2025-04-22clk: renesas: rzv2h: Use both CLK_ON and CLK_MON bits for clock state validationLad Prabhakar
Update the clock enable/disable logic to follow the latest hardware manual's guidelines, ensuring that both CLK_ON and CLK_MON bits are used to confirm the clock state. According to the manual, enabling a clock requires setting the CPG_CLK_ON bit and verifying the clock has started using the CPG_CLK_MON bit. Similarly, disabling a clock requires clearing the CPG_CLK_ON bit and confirming the clock has stopped via the CPG_CLK_MON bit. Modify `rzv2h_mod_clock_is_enabled()` to check CLK_MON first and then validate CLK_ON for a more accurate clock status evaluation.

2025-04-22clk: renesas: rzv2h: Add macro for defining static dividersLad Prabhakar
Unlike dynamic dividers, static dividers do not have a monitor bit. Introduce the `DEF_CSDIV()` macro for defining static dividers, ensuring consistency with existing dynamic divider macros. Additionally, introduce the `CSDIV_NO_MON` macro to indicate the absence of a monitor bit, allowing the monitoring step to be skipped when `mon` is set to `CSDIV_NO_MON`. Note, `rzv2h_cpg_ddiv_clk_register()` will be re-used instead of generic `clk_hw_register_divider_table()` for registering satic dividers as some of the static dividers require RMW operations.
