[PATCH 03/14] clk: renesas: rzg2l-cpg: Add support for MSTOP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

RZ/{G2L, V2L, G3S} based CPG versions have support for saving extra
power when clocks are disabled by activating module standby. This is done
though MSTOP specific registers that are part of CPG. Each individual
module have one or more bits associated in one MSTOP register (see table
"Registers for Module Standby Mode" from HW manuals). Hardware manual
associates modules' clocks to one or more MSTOP bits. There are 3 mappings
available (identified by researching RZ/G2L, RZ/G3S, RZ/V2L HW manuals):

case 1: N clocks mapped to N MSTOP bits (with N={0, ..., X})
case 2: N clocks mapped to 1 MSTOP bit  (with N={0, ..., X})
case 3: N clocks mapped to M MSTOP bits (with N={0, ..., X}, M={0, ..., Y})

Case 3 has been currently identified on RZ/V2L for VCPL4 module.

To cover all 3 cases the individual platform drivers will provide to
clock driver MSTOP register offset and associated bits in this register
as a bitmask and the clock driver will apply this bitmask to proper
MSTOP register.

As most of the modules have more than one clock and these clocks are
mapped to 1 MSTOP bitmap that need to be applied to MSTOP registers,
to avoid switching the module to/out of standby when the module has
enabled/disabled clocks a counter has been associated to each module
(though struct mstop::count) which is incremented/decremented every
time a module's clock is enabled/disabled and the settings to MSTOP
register are applied only when the counter reaches zero (counter zero
means either 1st clock of the module is going to be enabled or all clocks
of the module are going to be disabled).

The MSTOP functionality has been instantiated at the moment for RZ/G3S.
