The ICU block on the RZ/G3E SoC is almost identical to the one found on
the RZ/V2H SoC, with the following differences:
- The TINT register offset is 0x830 compared to 0x30 on RZ/V2H.
- The number of supported GPIO interrupts for TINT selection is 141
instead of 86.
- The pin index and TINT selection index are not in the 1:1 map
- The number of TSSR registers is 15 instead of 8
- Each TSSR register can program 2 TINTs instead of 4 TINTs
Add support for the RZ/G3E ICU driver.
v1->v2:
* Collected tags
* Split the simplification patch into two.
* Updated commit header and description for patch#4.
* Replaced devm_reset_control_get_optional_exclusive_deasserted()->
devm_reset_control_get_exclusive_deasserted().
* Moved simplification using devm_pm_runtime_enable() to patch#5.
* Aligned kernel doc, struct members and struct initializers in
a tabular fashion.
* Renamed the macro ICU_PB5_TINT->ICU_RZV2H_TSSEL_MAX_VAL.
* Replaced hexa decimal constant with ICU_RZV2H_TSSEL_MAX_VAL in struct
rzv2h_hw_params.
* Introduced ICU_RZG3E_{TSSEL_MAX_VAL,TINT_OFFSET} macros and used these
macros in struct rzv2h_hw_params rather than using the hex constants.
