85997a7cba clk: samsung: Don't build ARMv8 clock drivers on ARMv7
Currently the Exynos5433 (ARMv8 SoC) clock driver depends on ARCH_EXYNOS
so it is built also on ARMv7. This does not bring any kind of benefit.
There won't be a single kernel image for ARMv7 and ARMv8 SoCs (like
multi_v7 for ARMv7).

Instead build clock drivers only for respective SoC's architecture.

215cd9674f clk: samsung: Enable COMPILE_TEST for Samsung clocks
Enable the COMPILE_TEST to get build coverage of some of Samsung clock
controller drivers. Still some of them will be built only if
appropriate SoC is chosen (like SOC_EXYNOS4415 or ARCH_S3C64XX).

6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

6b4feaea25 clk: exynos: use irqsave version of spin_lock to avoid deadlock with irqs
It is allowed to enable/disable clocks from interrupts, so common Exynos
ARM clock management code for CPUfreq should use 'irqsave' version of
spin_lock calls to avoid potential deadlock caused by spin_lock recursion.
The same spin_lock is used by gate/mux clocks during enable/disable calls.

This deadlock, can be reproduced by enabling CPUfreq (ondemand or
userspace) and decoding video with s5p-mfc driver.

c0d6fe2f01 ARM: DT updates for v4.4
As usual, this is the massive branch we have for each release. Lots of
 various updates and additions of hardware descriptions on existing hardware,
 as well as the usual additions of new boards and SoCs.
 
 This is also the first release where we've started mixing 64- and 32-bit
 DT updates in one branch.
 
 (Specific details on what's actually here and new is pretty easy to tell
 from the diffstat, so there's little point in duplicating listing it here.)

b4dc272b60 clk: samsung: exynos5250: Add DISP1 clocks
When the DISP1 power domain is powered off, there's two clocks that need
to be temporarily reparented to OSC, and back to their original parents
when the domain is powered on again.

We expose these two clocks in the DT bindings so that the DT node of the
power domain can reference them.

d71fc239b6 ARM: SoC: late fixes and dependencies
This is a collection of a few late fixes and other misc. stuff that
 had dependencies on things being merged from other trees.
 
 The bulk of the changes are for samsung/exynos SoCs for some changes
 that needed a few minor reworks so ended up a bit late.  The others
 are mainly for qcom SoCs: a couple fixes and some DTS updates.
 
 There's one conflict with drivers/cpufreq/exynos-cpufreq.c because
 it's now been completely removed, but there were some fixes that hit
 mainline in the meantime.

modified a way that driver registers registers to core framework. This
change has not been applied to s5pv210 clocks driver, which has been
merged in parallel to that commit. This patch adds a missing call to
samsung_clk_of_add_provider(), so the driver is operational again.

e323d56eb0 clk: exynos4: Fix wrong clock for Exynos4x12 ADC
The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver.
However TSADC is present only on Exynos4210 so on Trats2 board (with
Exynos4412 SoC) the exynos-adc driver could not be probed:
   ERROR: could not get clock /adc@126C0000:adc(0)
   exynos-adc 126c0000.adc: failed getting clock, err = -2
   exynos-adc: probe of 126c0000.adc failed with error -2

Instead on Exynos4x12 SoCs the main clock used by Analog to Digital
Converter is located in different register and it is named in datasheet
as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock
is the same as purpose of TSADC from Exynos4210.

The patch adds gate clock for Exynos4x12 using the proper register so
backward compatibility is preserved. This fixes the probe of exynos-adc
driver on Exynos4x12 boards and allows accessing sensors connected to it
on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are

it and add in slab.h where files were relying on it to include

6ae5a0b46f clk: samsung: exynos4: add cpu clock configuration data and instantiate cpu clock
With the addition of the new Samsung specific cpu-clock type, the
arm clock can be represented as a cpu-clock type. Add the CPU clock
configuration data and instantiate the CPU clock type for Exynos4210.

Changes by Bartlomiej:
- fixed issue with wrong dividers being setup by Common Clock Framework
  (by an addition of CLK_RECALC_NEW_RATES clock flag to mout_apll clock,
  without this change cpufreq-dt driver showed ~10 mA larger energy
  consumption when compared to cpufreq-exynos one when "performance"
  cpufreq governor was used on Exynos4210 SoC based Origen board), this
  was probably meant to be workarounded by use of CLK_GET_RATE_NOCACHE
  and CLK_DIVIDER_READ_ONLY clock flags in the original patchset (in
  "[PATCH v12 6/6] clk: samsung: remove unused clock aliases and update
  clock flags") but using these flags is not sufficient to fix the issue
  observed
- removed Exynos5250 and Exynos5420 support for now

ddeac8d968 clk: samsung: add infrastructure to register cpu clocks
The CPU clock provider supplies the clock to the CPU clock domain. The
composition and organization of the CPU clock provider could vary among
Exynos SoCs. A CPU clock provider can be composed of clock mux, dividers
and gates. This patch defines a new clock type for CPU clock provider and
adds infrastructure to register the CPU clock providers for Samsung
platforms.

Changes by Bartlomiej:
- fixed issue with setting lower dividers before the parent clock speed
  was lowered (the issue resulted in lockup on Exynos4210 SoC based
  Origen board when "ondemand" cpufreq governor was stress tested)
- fixed missing spin_unlock on error in exynos_cpuclk_post_rate_change()
  problem by moving cfg_data search outside of the spin locked area
- removed leftover kfree() in exynos_register_cpu_clock() that could
  result in dereferencing the NULL pointer on error
- moved spin_lock earlier in exynos_cpuclk_pre_rate_change() to cover
  reading of E4210_SRC_CPU and E4210_DIV_CPU1 registers
- added missing "last chance" checks to wait_until_divider_stable() and
  wait_until_mux_stable() (needed in case that IRQ handling took long
  time to proceed and resulted in function printing incorrect error
  message about timeout)
- moved E4210_CPU_DIV[0,1]() macros just before their only users,
  this resulted in moving them from patch #2 to patch #3/6 ("clk:
  samsung: exynos4: add cpu clock configuration data and instantiate
  cpu clock")
- removed E5250_CPU_DIV[0,1](), E5420_EGL_DIV0() and E5420_KFC_DIV()
  macros for now
- added my Copyrights to drivers/clk/samsung/clk-cpu.c

Commit ae43b32891 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power
Management support v12") added pm support for the pl330 dma driver but
it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated
during suspend and this in turn makes its parent clock aclk266_g2d to
be gated. But the clock needs to be ungated prior suspend to allow the
system to be suspend and resumed correctly.

Add GATE_BUS_TOP register to the list of registers to be restored when
the system enters into a suspend state so aclk266_g2d will be ungated.

Thanks to Abhilash Kesavan for figuring out that this was the issue.

18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly 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 second major change
 is 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.

     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"

8856010029 clk: exynos5420: Add IDs for clocks used in DISP1 power domain
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.
