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).

2013-12-24serial: sh-sci: Compute overrun_bit without using baud rate algoLaurent Pinchart1-12/+14
The overrun bit index is a property of the hardware. It's currently computed based on a different and unrelated hardware property, the baud rate calculation algorithm.

2013-12-14ARM: shmobile: Add select MIGHT_HAVE_PCI for PCI-AHB bridge codeBen Dooks1-0/+4
The PCI sub-system is not enabled by default on ARM and on certain Renesas devices the build does not select it. This means that there are configurations that do not allow the AHB-PCI bridge used for the USB sub-systems to be built. For the R8A7790, R8A7791 and EMEV-2 select MIGHT_HAVE_PCI to allow the PCI drivers to be built. Also select MIGHT_HAVE_PCI for the multi-config where there may be many Reneasas devices selected.

2013-12-14serial: sh-sci: Don't enable/disable port from within break timerLaurent Pinchart1-4/+8
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.

2013-12-10ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACYLaurent Pinchart15-21/+26
SH-Mobile platforms are transitioning from non-multiplatform to multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has been created to group all multiplatform-enabled SH-Mobile SoCs. The existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't been converted yet. This arrangement works fine for the arch/ code, but lots of drivers needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on ARCH_SHMOBILE only. In order to avoid changing them, rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean ARCH_SHMOBILE configuration symbol that is selected by both ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.
