2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

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.

2016-04-11arc: get rid of running_on_hwAlexey Brodkin
ISS is obsolete now and nSIM is used for simulation instead. In its turn nSIM properly handles baud-rate settings so get rid of now useless check. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-03-14dm: serial: Remove duplicated carriage return characterAlison Wang
As the handling for carriage return and line feed is done in the common DM driver serial-uclass.c, such handling in some serial DM drivers is duplicated and need to be removed. Signed-off-by: Alison Wang <alison.wang@nxp.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-08-31dm: Use dev_get_addr() where possibleSimon Glass
This is a convenient way for a driver to get the hardware address of a device, when regmap or syscon are not being used. Change existing callers to use it as an example to others.

Now when all infrastructure in ARC is ready for it let's switch ARC UART to driver model. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Simon Glass <sjg@chromium.org>
2015-04-03serial/serial_arc: set registers address during compilationAlexey Brodkin
Being global variable with 0 value it falls into .bss area which we may only use after relocation to RAM. And right afetr relocation we zero .bss - effectively cleaing register address set for early console. Now with pre-set value "regs" variable is no longer in .bss and this way safely survives relocation. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

Use default_serial_puts() instead of duplicating the implementation. Signed-off-by: Axel Lin <axel.lin@ingics.com>
2014-02-21serial/serial_arc: switch from {read|write}l to {read|write}b accessorsAlexey Brodkin
This is required for proper functionality on big-endian targets. Memory-mapped registres of ARC UART are not 32-bit words but 8-bit bytes so on little-endian target either acessor (_l or _b) works fine. On big-endian only _b accessors works as expected.
