Huh?
This is used by PCIe PHY, as part of the power on procedures:
+static int hi3670_pcie_noc_power(struct hi3670_pcie_phy *phy, bool enable)
+{
+ struct device *dev = phy->dev;
+ u32 time = 100;
+ unsigned int val = NOC_PW_MASK;
+ int rst;
+
+ if (enable)
+ val = NOC_PW_MASK | NOC_PW_SET_BIT;
+ else
+ val = NOC_PW_MASK;
+ rst = enable ? 1 : 0;
+
+ regmap_write(phy->pmctrl, NOC_POWER_IDLEREQ_1, val);

Do you mean like this?

I'll move it to the USB patch series, where the PMIC is added.

This hunk should be on patch 03/10. Probably some rebase added it here by
mistake. I'll fix it on v8.
