2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2016-09-23treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

2016-07-23ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()Masahiro Yamada
This does not have much impact on behavior, but makes code look more more like Linux. The use of devm_ioremap() often helps to delete .remove callbacks entirely. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-03-31serial: uniphier: use devm_get_addr() to get base addressMasahiro Yamada
Currently, fdtdec_get_addr_size() does not support the address translation, so it cannot handle device trees with non-straight "ranges" properties. (This would be a problem with DTS for UniPhier ARMv8 SoCs.) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2015-08-30serial: uniphier: drop platform data supportMasahiro Yamada
This driver is enabled only for UniPhier SoCs and ARCH_UNIPHIER now selects OF_CONTROL and SPL_OF_CONTROL. This driver no longer needs to support platform data configuration. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2015-08-18of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

2015-05-30ARM: UniPhier: replace <asm/io.h> with <linux/io.h>Masahiro Yamada
In the Linux coding style, it is recommended to include <linux/io.h> rather than <asm/io.h>. Follow this trend. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2015-04-18common: Make sure arch-specific map_sysmem() is definedJoe Hershberger
In the case where the arch defines a custom map_sysmem(), make sure that including just mapmem.h is sufficient to have these functions as they are when the arch does not override it. Also split the non-arch specific functions out of common.h Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2015-02-28serial: UniPhier: move LCR register setting to probe functionMasahiro Yamada
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>
2015-02-28serial: UniPhier: use 32 bit register accessMasahiro Yamada
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>

2014-11-11serial: UniPhier: borrow macros from linux/serial_reg.hMasahiro Yamada
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>

2014-10-24dm: serial: use Driver Model for UniPhier serial driverMasahiro Yamada
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>
