Series clk: renesas: rzg2l-cpg: Drop PM domain abstraction for MSTOP | expand

Commit Message

Claudiu Beznea April 10, 2025, 2:06 p.m. UTC 
From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

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 bits
2/ Set module CLKON bits

B/ Switching to Standby State (e.g., during remove):
1/ Clear CLKON bits
2/ Set MSTOP bits

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 bits
2/ Clear CLKON bits

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 bits
2/ Clear MSTOP bits

B/ Switching to Standby State (e.g., during remove):
1/ Set MSTOP bits
2/ Clear CLKON bits

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.

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.
