8a02fcf8a0 Allwinner clock patches for 4.13
Some new clock units are supported, for the display clocks unsed in the
 newer SoCs, and the A83T PRCM.
 
 There is also a bunch of minor fixes for clocks that are not used by
 anyone, and reworks needed by drivers that will land in 4.13.

05359be117 clk: sunxi-ng: Add driver for A83T CCU
The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.

Like the A80, the SoC does not have a low speed 32.768 kHz oscillator.
Unlike the A80, there is no clock input either. The only low speed clock
available is the internal oscillator which runs at around 16 MHz,
divided by 512, yielding a low speed clock around 31.250 kHz.

Also, the MMC2 module clock supports switching to a "new timing" mode.
This mode divides the clock output by half, and disables the CCU based
clock delays. The MMC controller must be configure to the same mode,
and then use its internal clock delays.

This driver does not support runtime switching of the timing modes.
Instead, the new timing mode is enforced at probe time. Consumers can
check which mode is active by trying to get the current phase delay
of the MMC2 phase clocks, which will return -ENOTSUPP if the new
timing mode is active.

b5a53b61a2 Sort of on the quieter side this time, which is probably due more
to me not catching up as quickly on patch review than anything else.
 Overall it seems normal though, a few small changes to the core, mostly
 small non-critical fixes here and there as well as driver updates for new
 and existing hardware support. The biggest things are the TI clk driver
 rework to lay the groundwork for clkctrl support in the next merge window
 and the AmLogic audio/graphics clk support.
 
 Core:
  * clk_possible_parents debugfs file so we know which parents a clk
    could possibly have
  * Fix to make clk rate change notifiers stop on the first failure instead
    of continuing
 
 New Drivers:
  * Mediatek MT6797 SoCs
  * hi655x PMIC clks
  * AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
  * Allwinner H5 SoCs and PRCM hardware
 
 Updates:
  * Nvidia Tegra T210 cleanups and non-critical fixes
  * TI OMAP cleanups in preparation for clkctrl support
  * Trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
  * ZTE zx296718 SoC VGA clks
  * Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
  * Support for IDT VersaClock 5P49V5935
  * Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3 support

85d604902e ARM: Device-tree updates
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 Major new platforms:
 
  - Gemini has been ported to DT, so a handful of "new" platforms moved over
    from board files
  - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288 SoM and RDK
  - A bunch of embedded platforms, several Linksys platforms, Synology DS116,
  - Motorola Droid4 (really old OMAP-based phone) support is added.
 
 Some refactorings, i.e. Allwinner H3/H5 support is commonalized.
 
 And lots of smaller changes, cleanups, etc. See shortlog for more description
 
 We're adding ability to cross-include DT files between arm and arm64,
 by creating appropriate links in the dt-include directory, and using arm/
 and arm64/ as include prefixes. This will avoid other local hacks such as
 per-file links between the two arch trees (this broke for external mirroring
 of DT contents). Now they can just provide their own appropriate dt-include
 hierarcy per platform.

5579836026 General rockchip clock changes for 4.12. Contains some new clock-ids
as well as fixups of the clock-ids on rk3368 timers, which were unused
 and completely wrong (more and differently named timers).
 Also there is one new clock on rk3328 using the muxgrf type, a fix for
 pll enablement which should wait for the pll to lock before continuing,
 some more critical clocks and the rename of the rk1108 to rv1108, as the
 soc seems to have been using a preliminary name before its actual release.
 The plan is to have the driver changes (pinctrl, clk) go through the
 respective maintainer trees and once everything landed in mainline do
 the rename of the devicetree files. With the dts-include change in the
 clock rename, we also keep everything compiling and thus bisectability.
