2017-06-01clk: Modify xlate() method for livetreeSimon Glass
Update the xlate() method to use ofnode_phandle_args instead of the fdtdec variant. This will allow drivers to support a live device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: core: Update device_bind_driver_to_node() to use ofnodeSimon Glass
Adjust this function to us an ofnode instead of an offset, so it can be used with livetree. This involves updating all callers. Signed-off-by: Simon Glass <sjg@chromium.org>
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.

2017-06-01dm: Use dm.h header when driver mode is usedSimon Glass
This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass <sjg@chromium.org>

2017-03-16dm: allow limiting pre-reloc markings to spl or tplHeiko Stübner
Right now the u-boot,dm-pre-reloc flag will make each marked node always appear in both spl and tpl. But systems needing an additional tpl might have special constraints for each, like the spl needing to be very tiny. So introduce two additional flags to mark nodes for only spl or tpl environments and introduce a function dm_fdt_pre_reloc to automate the necessary checks in code instances checking for pre-relocation flags. The behaviour of the original flag stays untouched and still marks a node for both spl and tpl.

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.

2016-10-28clk: at91: Improve the clock implementationWenyou Yang
For the peripheral clock, provide the clock ops for the clock provider, such as spi0_clk. The .of_xlate is to get the clk->id, the .enable is to enable the spi0 peripheral clock, the .get_rate is to get the clock frequency. The driver for periph32ck node is responsible for recursively binding its children as clk devices, not provide the clock ops. So do the generated clock and system clock.

2016-10-28clk: at91: Fix at91-pmc and at91-sckc's class IDWenyou Yang
The at91-pmc and at91-sckc aren't the clock providers, change their class ID from UCLASS_CLK to UCLASS_SIMPLE_BUS, they also don't need to bind the child nodes explicitly, the .post_bind callback of simple_bus uclass will do it for them.
