Bartosz Golaszewski f82bf3c579 power: sequencing: make the QCom PMU pwrseq driver depend on CONFIG_OF
This driver uses various OF-specific functions and depends on phandle
parsing. There's no reason to make it available to non-OF systems so add
a relevant dependency switch to its Kconfig entry.

Fixes: 2f1630f437 ("power: pwrseq: add a driver for the PMU module on the QCom WCN chipsets")

This subsystem is designed to control power to devices that share

help
Say Y here to enable the power sequencing driver for Qualcomm
WCN Bluetooth/WLAN chipsets.
Typically, a package from the Qualcomm WCN family contains the BT
and WLAN modules whose power is controlled by the PMU module. As the
former two share the power-up sequence which is executed by the PMU,
this driver is needed for correct power control or else we'd risk not
respecting the required delays between enabling Bluetooth and WLAN.
