* serial: sh: fix internal clock source on SCIFVladimir Barinov2015-02-25-2/+3
| | | | | | | | | | | | The formula to calculate SCIF BRR for R-Car H2/M2/E2 SoCs is as follows: BRR = pclk / (64 * 2^(2n-1) * baudrate) - 1, the prescaler is 0 due to SCSMR settings, hence n=0 Also SCSCR must be set to use internal or external clock source.

* sh: move CONFIG_{SH2, SH2A, SH3, SH4} to KconfigMasahiro Yamada2014-11-13-1/+1
| | | | | | | | | | | This commit moves CONFIG_SH2, CONFIG_SH2A, CONFIG_SH3, CONFIG_SH4 to Kconfig renaming into CONFIG_CPU_SH2, CONFIG_CPU_SH2A, CONFIG_CPU_SH3, CONFIG_CPU_SH4, respectively because arch/sh/Kconfig of Linux uses CONFIG_CPU_SH* convention.
