f6e7f07c17 ARM: UniPhier: replace <asm/io.h> with <linux/io.h>
In the Linux coding style, it is recommended to include <linux/io.h>
rather than <asm/io.h>.  Follow this trend.

0eb25b6196 common: Make sure arch-specific map_sysmem() is defined
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

099cf77c15 serial: UniPhier: move LCR register setting to probe function
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.

d0c47b3ef7 serial: UniPhier: use 32 bit register access
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.

325b708a61 serial: UniPhier: borrow macros from linux/serial_reg.h
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>.

d064cbffff dm: serial: use Driver Model for UniPhier serial driver
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.
