Hi David, Jonas,

Two concrete data points for the choice in this driver, on top of the general pattern Jonas mentioned:

- pcie_dw_rockchip, the consumer that will drive this clock on rock-5-itx, uses regulator_set_enable_if_allowed() itself for its own vpcie3v3 supply, so the gated-fixed-clock driver runs the exact same code path through the regulator core.

- vcc3v3_mkey on rock-5-itx is currently marked regulator-always-on in the u-boot dtsi, so the strict variant would surface -EACCES on every probe.

Thanks for the review.

Daniele
