d3cb46aa8c rockchip: Init clocks again when chain-loading
Detect with a previous boot loader has already set up the clocks and set
them up again so that U-Boot gets what it expects.

b223c1aead rockchip: rk3288: Convert clock driver to use shifted masks
Shifted masks are the standard approach with rockchip since it allows
use of the mask without shifting it each time. Update the definitions and
the driver to match.

a821c4af79 dm: Rename dev_addr..() functions
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.

6496498a62 rockchip: clk: rk3288: limit gpll and cpll init to SPL build
The gpll and cpll init values are only used in rk_clk_init in the SPL
and therefore produce compile time warnings in regular uboot builds.
Fix that with an #ifdef.

3a8a42d955 rockchip: clk: Support setting ACLK
Add basic support for setting the ARM clock, since this allows us to run
at maximum speed in U-Boot. Currently only a single speed is supported
(1.8GHz).

5564ed5dd9 rockchip: rk3288: Move rockchip_get_cru() out of the driver
This function is called from outside the driver. It should be placed into
common SoC code. Move it.

abd0128eb1 rockchip: remove log2 reimplementation from clock drivers
The already available ilog2 function does exactly the same in the common
case than the log2 function the current clock-driver reimplement.
So, simply move to that one.

aff8795c01 move: rockchip: move clock drivers into a subdirectory
With the number of Rockchip clock drivers increasing, don't clutter up
the core drivers/clk directory with them and instead move them out of
the way into a separate subdirectory.
