Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

Exynos 3250, 4415 drivers cleanup by using common code
and addition of clock definitions for DVFS on Exynos4.
|
|
When a power domain is powered off on Exynos5420 SoC, the input clocks of
the devices attached to this power domain are re-parented to oscclk and
restored to the original parent after powering on the power domain.
So a reference to the input and parent clocks for the devices attached to
a power domain are needed to be able to do the re-parenting. The DISP1 pd
includes modules which uses the following clocks:
ACLK_200_DISP1 (MIXER and HDMILINK)
ACLK_300_DISP1 (FIMD1)
ACLK_400_DISP1 (Internal Buses)
Each of these clocks are generated as the output of a clock mux so add an
ID for all of these clock muxes and their parents to be referenced in the
DISP1 power domain device node.

The memory allocated by basic clock divider/gate/mux (struct clk_gate,

Audio subsystem clocks are located in separate block. On Exynos 5420 if
clock for this block (from main clock domain) 'mau_epll' is gated then
any read or write to audss registers will block.
This kind of boot hang was observed on Arndale Octa and Peach Pi/Pit
after introducing runtime PM to pl330 DMA driver. After that commit the
'mau_epll' was gated, because the "amba" clock was disabled and there
were no more users of mau_epll.
The system hang on one of steps:
1. Disabling unused clocks from audss block.
2. During audss GPIO setup (just before probing i2s0 because
samsung_pinmux_setup() tried to access memory from audss block which was
gated.
Add a workaround for this by enabling the 'mau_epll' clock in probe.

In addition CLK_SET_RATE_PARENT flag is dropped from sclk_g3d, because

Add clock provider for clocks in DMC domain including EPLL and BPLL. The
DMC clocks are necessary for Exynos3 devfreq driver.
The DMC clock domain uses different address space (0x105C0000) than
standard clock domain (0x10030000 - 0x10050000). The difference is huge
enough to add new DT node for the clock provider, rather than extending
existing address space.

Pull ARM SoC platform changes from Olof Johansson:
"This is the bulk of new SoC enablement and other platform changes for
3.17:
- Samsung S5PV210 has been converted to DT and multiplatform
- Clock drivers and bindings for some of the lower-end i.MX 1/2
platforms
- Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood
- Hwmod data for TI AM43xx and DRA7 platforms
- More additions of Renesas shmobile platform support
- Removal of plat-samsung contents that can be removed with S5PV210
being multiplatform/DT-enabled and the other two old platforms
being removed
New platforms (most with only basic support right now):
- Hisilicon X5HD2 settop box chipset is introduced
- Mediatek MT6589 (mobile chipset) is introduced
- Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code"

Pull clock framework updates from Mike Turquette:
"The clock framework changes for 3.17 are mostly additions of new clock
drivers and fixes/enhancements to existing clock drivers. There are
also some non-critical fixes and improvements to the framework core.
Changes to the clock framework core include:
- improvements to printks on errors
- flattening the previously hierarchal structure of per-clock entries
in debugfs
- allow per-clock debugfs entries that are specific to a particular
clock driver
- configure initial clock parent and/or initial clock rate from
Device Tree
- several feature enhancements to the composite clock type
- misc fixes
New clock drivers added include:
- TI Palmas PMIC
- Allwinner A23 SoC
- Qualcomm APQ8084 and IPQ8064 SoCs
- Rockchip rk3188, rk3066 and rk3288 SoCs
- STMicroelectronics STiH407 SoC
- Cirrus Logic CLPS711X SoC
Many fixes, feature enhancements and further clock tree support for
existing clock drivers also were merged, such as Samsung's "ARMCLK
down" power saving feature for their Exynos4 & Exynos5 SoCs"
