2013-12-24serial: sh-sci: Rework baud rate calculationLaurent Pinchart2-7/+32
Computing the baud rate register value requires knowledge of the hardware sampling rate. This information is currently encoded in a baud rate calculation algorithm ID passed through platform data. However, it can be derived from the port type directly in most cases. Compute the sampling rate internally in the driver if the baud rate calculation algorithm ID isn't specified, and allow platforms to override the sampling rate through platform data in special cases (this is only required for SCIFA ports on sh7723 and sh7724, the reason needs to be investigated).

2013-12-23irq-renesas-irqc: simplify irq_set_type() methodSergei Shtylyov1-10/+7
Value 0 of the sense selection field of CONFIG_n register means "disable event detection" and serves in irqc_sense[] for marking the invalid values of the IRQ type (by just omitting initializers). There is no need for INTC_IRQ_SENSE_VALID and hence INTC_IRQ_SENSE() as all field values matching to the valid IRQ types are non-zero anyway.
