linux-gbmc(npcm): i2c: Add clock toggle recovery During init of the bus, the module checks that the bus is idle. If one of the lines are stuck try to recover them first before failing. Sometimes SDA and SCL are low if improper reset occurs (e.g., reboot). Upstream-process: https://patchwork.ozlabs.org/project/linux-i2c/patch/20250327193816.670658-1-mohammed.0.elbadry@gmail.com/ Tested: Repeated hardware lockup and can see bus recovering.
