2014-01-06ARM: shmobile: r8a7790: Fix I2C controller namesValentine Barshak
This fixes the issue introduced by the following commit: b448c904f5058b6c "ARM: shmobile: r8a7790: add I2C support" The R8A7790 is an R-Car Gen2 SoC. The clock division factor (CDF) width is 3 bits on Gen2 as opposed to 2 bits on Gen1. Fix the device names for R8A7790 SoC to make the R-Car I2C driver configure the hardware properly. Changes in V2: * rebased on top of the latest branch; * capitalized ARM in the subject line; * noted the commit that caused the issue in the log.

2013-12-24serial: sh-sci: Rework baud rate calculationLaurent Pinchart
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).

2013-12-14serial: sh-sci: Don't enable/disable port from within break timerLaurent Pinchart
The break timer accesses hardware registers and thus requires the port to be enabled. It currently ensures this by enabling the port at the beginning of the timer handler, and disabling it at the end. However, the enable/disable operations call the runtime PM sync functions, which are not allowed in atomic context. The current situation is thus broken. This change relies on non-atomic code to enable/disable the port. The break timer will only be started from the IRQ handler, which already runs with the port enabled. We just need to ensure that the port won't be disabled with the timer running, and that's easily done by just cancelling the timer in the port disable function.
