* ARM: UniPhier: adjust device trees for business transferMasahiro Yamada2015-03-15-3/+4
| | | | | | | Panasonic's System LSI products, UniPhier SoC family, have been transferred to Socionext Inc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* serial: UniPhier: move LCR register setting to probe functionMasahiro Yamada2015-03-01-9/+11
| | | | | | | We do not have to set the LCR register every time we change the baud-rate. We just need to set it up once in the probe function. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* serial: UniPhier: use 32 bit register accessMasahiro Yamada2015-03-01-28/+26
| | | | | | | | For PH1-Pro4, the 8 bit write access to LCR register (offset = 0x11) is not working correctly. As a side effect, it also modifies MCR register (offset = 0x10) and results in unexpected behavior. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* serial: UniPhier: support OF configurationMasahiro Yamada2014-11-28-8/+11
| | | | | | | This commit implements the ofdata_to_platdata handler for the UniPhier serial driver and adds serial device nodes to the device tree sources. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* serial: UniPhier: borrow macros from linux/serial_reg.hMasahiro Yamada2014-11-12-13/+2
| | | | | | | | | The same bit-field macros are defined in include/linux/serial_reg.h so let's include it and delete duplicated defines. Also, remove unnecessary inclusion of <common.h>. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* serial: UniPhier: add static to locally used functionsMasahiro Yamada2014-10-29-3/+3
| | | | Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* serial: UniPhier: add .pending handlerMasahiro Yamada2014-10-29-0/+11
| | | | | | Without .pending handler, tstc() function always returns 1. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* dm: serial: use Driver Model for UniPhier serial driverMasahiro Yamada2014-10-23-126/+73
| | | | | | | | | | | | | | | | | This commit converts UniPhier on-chip serial driver to driver model. Since UniPhier SoCs do not have Device Tree support, some board files should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories. (Device Tree support for UniPhier platform is still under way.) Now the base address and master clock frequency are passed from platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and CONFIG_SYS_UNIPHIER_UART_CLK should be removed. Tested on UniPhier PH1-LD4 ref board. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>
* serial: add UniPhier serial driverMasahiro Yamada2014-10-05-0/+204
The driver for on-chip UART used on Panasonic UniPhier platform. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
