Date
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Rename label vdd2_reg to reg_1v05.
Rename label ldo6_reg to reg_1v05_avdd_plle.
Drop unused labels.
Rename regulator tps62362-vout to +V1.2_VDD_CORE.
Reorder TPS65911 properties.
Rename +V1.05 to +V1.05_AVDD_PLLE.
Add ti,en-ck32k-xtal.
Specify TPS62362 vin-supply.
Drop spurious newline in TPS62362 properties.
Rename vddio_sdmmc_1v8_reg to reg_1v8_vddio_sdmmc3.
Rename +V1.05 to +V1.05_AVDD_PLLE.
