…SILO-104 peripheral.arch:arm:boot:dts: update imx6ul-ts7250v3-silo104-i2c-gpio.dtso to include driver requirements.
… cell registration on SILO, fix SILO debug loop, and extend regmap to cover SILO block (reads at WIZ_SILO_BASE..+16; writes to CONTROL(+2), REQ_CUR(+4), CRITICAL_PCT(+9), STARTUP_REQ_CUR(+12), MIN_PWR_ON_PCT(+13)). drivers/iio/adc/tswizard_adc.c: Derive IIO device name from DT node with dev_name() fallback and add “technologic,wizard-adc” to OF match table (alongside legacy “technologic,tswizard-adc”). arch/arm/boot/dts/nxp/imx/imx6ul-ts7250v3-silo104-i2c-gpio.dtso: Align Wizard child nodes with driver compatibles and wire the SILO interrupt directly to fpga_intc so the driver probes without deferral.
…top register corruption.

This series introduces the embeddedTS Wizard microcontroller integration:
MFD core with a shared regmap and model/feature discovery
IIO ADC and temperature support
RTC with epoch, alarm, battery detection, and ppb calibration
Reset controller handling reboot and poweroff
SILO-104 supercaps power_supply driver with IRQ-driven updates
DTS and overlay to wire the TS‑7250‑V3 and SILO‑104 add-on
Together this provides a clean, SoC-agnostic integration path for power management, telemetry, and system control on embeddedTS platforms.
Enable CONFIG_MFD_TS_WIZARD, ADC/TEMP/RTC/RESET options and CONFIG_POWER_SUPPLY. DTS wiring is added for TS‑7250‑V3; an overlay is provided to attach SILO‑104 via i2c‑gpio on the PC/104 connector.
Thanks for reviewing!
