Carlos Song f2a3f51365 i2c: imx-lpi2c: change to PIO mode in system-wide suspend/resume progress ... EDMA resumes early and suspends late in the system power transition sequence, while LPI2C enters the NOIRQ stage for both suspend and resume. This means LPI2C resources become available before EDMA is fully resumed. Once IRQs are enabled, a slave device may immediately trigger an LPI2C transfer. If the transfer length meets DMA requirements, the driver will attempt to use EDMA even though EDMA may still be unavailable. This timing gap can lead to transfer failures. To prevent this, force LPI2C to use PIO mode during system-wide suspend and resume transitions. This reduces dependency on EDMA and avoids using an unready DMA resource.
