[PATCH v5 5/9] mfd: cgbc: Use PLATFORM_DEVID_AUTO for child device registration
From: Thomas Richard (congatec GmbH)
Date: Tue Nov 03 2026 - 11:56:09 EST
Since parameters are now passed to the i2c-cgbc driver via platform
data, the I2C driver no longer depends on the platform device ID to probe
the correct I2C buses. Drop the hardcoded cell ID in favor of
PLATFORM_DEVID_AUTO.
