2024-08-02ACPI: PMIC: Remove unneeded check in tps68470_pmic_opregion_probe()Aleksandr Mishin
In tps68470_pmic_opregion_probe() pointer 'dev' is compared to NULL which is useless. Fix this issue by removing unneeded check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2017-10-03ACPI / PMIC: Add TI PMIC TPS68470 operation region driverRajmohan Mani
The Kabylake platform coreboot (Chrome OS equivalent of BIOS) has defined 4 operation regions for the TI TPS68470 PMIC. These operation regions are to enable/disable voltage regulators, configure voltage regulators, enable/disable clocks and to configure clocks. This config adds ACPI operation region support for TI TPS68470 PMIC. TPS68470 device is an advanced power management unit that powers a Compact Camera Module (CCM), generates clocks for image sensors, drives a dual LED for flash and incorporates two LED drivers for general purpose indicators. This driver enables ACPI operation region support to control voltage regulators and clocks for the TPS68470 PMIC.
