Like other i2c controllers we see deadlock issues with clock prepare mutex. In our case this came up with a clock output of a rtc connected to i2c bus. This issue has already been fixed upstream by: (d9a22d71) i2c: imx: avoid taking clk_prepare mutex in PM callbacks But was reintroduced by a wrongly resolved merge conflict with this commit: (d59c7185) MLK-11403: I2C: imx: restore pin setting for i2c So again we keep the i2c clock prepared and only enable and disable it for a transfer.
