7196c52c93 clk: imx6q: fix typo in CAN clock definition
commit ee36027427 ("clk: imx: Add clock support for imx6qp")
introduced a regression due to a subtle typo in the 'can_root' clock
definition. The effect is that trying to configure the bitrate of the
can interfaces fails with -EDOM or produces a division by zero error
due to the clock_freq of the can serial clock being reported as '0'.

2aac7ddf9a clk: qcom: ipq4019: add some fixed clocks for ddrppl and fepll
Drivers for these don't exist yet so we will add them as fixed clocks
so we don't BUG() if we change clocks that reference these clocks.

33c1f638a0 The clk changes for this release cycle are mostly dominated by
new device support in terms of LoC, but there has been some cleanup
 in the core as well as the usual minor clk additions to various
 drivers.
 
 Core:
 
  - parent tracking has been simplified
 
  - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
 
  - of_clk_init() doesn't consider disabled DT nodes anymore
 
  - clk_unregister() had an error path bug squashed
 
  - of_clk_get_parent_count() has been fixed to only return unsigned ints
 
  - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
 
 New Drivers:
 
  - NXP LPC18xx creg
 
  - QCOM IPQ4019 GCC
 
  - TI dm814x ADPLL
 
  - i.MX6QP
 
 Updates:
 
  - Cyngus audio clks found on Broadcom iProc devices
 
  - Non-critical fixes for BCM2385 PLLs
 
  - Samsung exynos5433 updates for clk id errors, HDMI support,
    suspend/resume simplifications
 
  - USB, CAN, LVDS, and FCP clks on shmobile devices
 
  - sunxi got support for more clks on new SoCs and went through a minor
    refactoring/rewrite to use a simpler factor clk construct
 
  - rockchip added some more clk ids and added suport for fraction dividers
 
  - QCOM GDSCs in msm8996
 
  - A new devm helper to make adding custom actions simpler (acked by Greg)

46e595a17d ARM: SoC driver updates for v4.6
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons:
 
 - Rockchip rk3368 gains power domain support
 - Small updates for the ARM spmi driver
 - The Atmel PMC driver saw a larger rework, touching both
   arch/arm/mach-at91 and drivers/clk/at91
 - All reset controller driver changes alway get merged through
   arm-soc, though this time the largest change is the addition
   of a MIPS pistachio reset driver
 - One bugfix for the NXP (formerly Freescale) i.MX weim bus driver

   - Decompressor cleanups from Masahiro Yamada

   - Avoid printing an error for a missing L2 cache

   - Remove some duplicated symbols in System.map, and move
     vectors/stubs back into kernel VMA

   - Various low priority fixes from Arnd

   - Updates to allow bus match functions to return negative errno
     values, touching some drivers and the driver core.  Greg has acked
     these changes.

   - Virtualisation platform udpates form Jean-Philippe Brucker.

   - Security enhancements from Kees Cook

   - Rework some Kconfig dependencies and move PSCI idle management code
     out of arch/arm into drivers/firmware/psci.c

   - ARM DMA mapping updates, touching media, acked by Mauro.

   - Fix places in ARM code which should be using virt_to_idmap() so
     that Keystone2 can work.

   - Fix Marvell Tauros2 to work again with non-DT boots.

   - Provide a delay timer for ARM Orion platforms"

2c6fae2501 clk: rockchip: associate SCLK_MAC_PLL and disable reparenting on rk3036
The emac needs constant and very specific rate but the possible PLL-sources
are very limited, so we expect the PLL source to be set manually on per
board and don't want it to get changed in an automatic way later.
So add the necessary clock-id and disable reparenting on set_rate calls.

4d3ac66624 clk: bcm2835: fix check of error code returned by devm_ioremap_resource()
The change fixes potential oops while accessing iomem on invalid

The devm_ioremap_resource() function returns ERR_PTR() and never
returns NULL, which makes useless a following check for NULL.
