If anyone has any objections, please let me know. ------------------ From: Konrad Dybcio [ Upstream commit 58ce9a2b9099bb26aed55d4e350c32af94930532 ] When the I2C controller is disabled, no communication is expected to take place. Without traffic on the bus, the pull-up is unnecessary. Both the vendor kernel for this platform and DTs of other SoCs in upstream concur this logic. Change the default and clean up now-NOP overrides.
