[PATCH v2 1/2] arm64: dts: mediatek: mt8390-genio-700-evk: update regulator names

From: Macpaul Lin
Date: Mon Oct 07 2024 - 05:03:08 EST

Update regulator names to match schematics, replacing generic terms.
1. Add system wide 'reg_vsys' node for 4.2V power rail.
2. Add 'reg_vsys' node as 'vin-supply' for the following nodes
- common_fixed_5v, edp_panel_fixed_3v3, gpio_fixed_3v3, sdio_fixed_3v3,
touch0_fixed_3v3, usb_hub_fixed_3v3, usb_p0_vbus, and usb_p1_vbus.
3. Update regulator names according to the stable output name on
schematics.
- vdd_5v, vedp_3v3, ext_3v3, vio18_conn, wifi_3v3, vio33_tp1, vhub_3v3,
vbus_p0, vbus_p1.
- vcn18_pmu, vcn33_2_pmu, dvdd_proc_l, dvdd_core, vpa_pmu, dvdd_adsp,
va12_abb2_pmu, vsim1_pmu, vufs18_pmu.
4. Remove usb_hub_reset_1v8. Use 'hub' node to probe USB HUB
in subsequent patches.
