2014-08-09serial: sh: Add support External Clock modeNobuhiro Iwamatsu
R8A7780 and R7A7791 of rmobile supports External Clock mode, and these uses different from Internal Clock mode registers and calculations to the baud rate setting. This adds function for External Clock mode. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2013-10-17serial: sh: Add support R8A7790Nobuhiro Iwamatsu
This adds the preset value to register, and setup of baudrate. Signed-off-by: Kouei Abe <kouei.abe.cp@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
2013-10-17serial: sh: Change definition of clock of SCIFNobuhiro Iwamatsu
The former SH/SCIF driver had calculated baudrate based on CONFIG_SYS_CLK_FREQ. The newest SH/SCIF needs calculation of the clock for SCIF. This patch defines clock CONFIG_SH_SCIF_CLK_FREQ for SCIF and changes it to CONFIG_SH_SCIF_CLK_FREQ from CONFIG_SYS_CLK_FREQ.

2012-11-30serial: serial_sh: bugfix: autoboot fails if serial console is not connectedTetsuyuki Kobayashi
On kzm9g board (rmobile SoC), autoboot fails if serial console cable is not connected. When serial cable is not connected, serial error occurs and some garbage comes in data register. sh_serial_tstc() in serial_sh.c does not check error status and misunderstand there is some input data. It is the reason that autoboot fails. This patch adds checking error status in sh_serial_tstc(). This patch is based on v2013.01-rc1 tag of u-boot master git.

2012-10-17serial: Use default_serial_puts() in driversMarek Vasut
Replace the in-place ad-hoc implementation of serial_puts() within the drivers with default_serial_puts() call. This cuts down on the code duplication quite a bit. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tom Rini <trini@ti.com>
2012-10-15serial: Remove CONFIG_SERIAL_MULTI from serial driversMarek Vasut
Remove the support for not-CONFIG_SERIAL_MULTI part from serial port drivers and some board files. Since CONFIG_SERIAL_MULTI is now enabled by default, that part is a dead code. Remove it.

2012-10-15serial: sh: Implement CONFIG_SERIAL_MULTI into sh serial driverMarek Vasut
Implement support for CONFIG_SERIAL_MULTI into sh serial driver. This driver was so far only usable directly, but this patch also adds support for the multi method. This allows using more than one serial driver alongside the sh driver. Also, add a weak implementation of default_serial_console() returning this driver.
