serial: 8250_omap: Work around errata spurious IRQs with DMA As per Advisory 27 of AM437x Silicon errata document, Spurious UART interrupts may occur when DMA mode (FCR.DMA_MODE) is enabled. The Interrupt Controller flags that a UART interrupt has occurred; however, the associated IT_PENDING bit remains set to 1, indicating that no interrupt is pending. Acknowledge the spurious interrupts for every occurrence as workaround. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
