76c7473f75 ARM: davinci: da850: switch to using the clocksource driver
We now have a proper clocksource driver for davinci. Switch the da850
platform to using it.

d470df3bc5 ARM: davinci: WARN_ON() if clk_get() fails
Currently the timer code checks if the clock pointer passed to it is
good (!IS_ERR(clk)). The new clocksource driver expects the clock to
be functional and doesn't perform any checks so emit a warning if
clk_get() fails. Apply this to all davinci platforms.

62e59c4e69 clk: Remove io.h from clk-provider.h
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Found with this grep:

that driver doesn't use clk consumer APIs.

6567954b8e ARM: davinci: cp-intc: use the new-style config structure
Modify the cp-intc driver to take all its configuration from the new

Move the declaration for davinci_cp_intc_init() to
irq-davinci-cp-intc.h and make it take the new config structure as
parameter. Convert all users to the new version.

Also: since the two da8xx SoCs default all irq priorities to 7, just
drop the priority configuration at all and hardcode the channels to 7.

It will simplify the driver code and make our lives easier when it
comes to device-tree support.

The existence of irqs.h in mach-davinci/include/mach only makes sense
without SPARSE_IRQ as it's then expected to define NR_IRQS and is

be moved to mach-davinci and used as the source of HW interrupt numbers.

While updating the includes in various files - also rearrange the
headers by directory (linux/asm/mach).

482db8893e ARM: davinci: da850: add new clock init using common clock framework
This adds the new board-specific clock init in mach-davinci/da850.c
using the new common clock framework drivers.

The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.

Also clean up the #includes since we are adding some here.

Some CFGCHIP macros were removed because we are now including
linux/mfd/da8xx-cfgchip.h which defines the same values.

a7da5277cd ARM: davinci: pass clock as parameter to davinci_timer_init()
This changes davinci_timer_init() so that we pass the clock as a
parameter instead of using clk_get(). This is done in preparation
for converting to the common clock framework.

It removes the requirement that we have to have a clock with con_id
of "timer0", which will be good for DT bindings since clock-names =
"timer0" doesn't really make sense.

Also, drop use of extern in header file since we are touching the
definition.

96c081735d ARM: davinci: move davinci_clk_init() to init_time
This moves the call of davinci_clk_init() from map_io to init_time for all
boards.

This is the proper place to init clocks. This is also done in preparation
for moving to the common clock framework.

dm646x is a special case because we need to handle different ref_clk rates
depending on which board is being used. The clock init in this case is
modified to set the rate before registering the clocks instead of using
davinci_set_refclk_rate() to recalculate the entire clock tree after all
of the clocks are registered.

Also, the cpu_clks field is removed from struct davinci_soc_info since it
is no longer needed.

adbc128fa8 ARM: SoC platform updates for 4.16
These are mostly minor bugfixes, cleanup and many defconfig updates to
 support added drivers. In particular OMAP and PXA keep cleaning up the
 legacy code base, as usual.
 
 Nvidia adds some more SoC support code for Tegra 186.
 
 For the first time on years, we are actually adding a non-DT platform for,
 the EP93xx based Liebherr controller BK3.1. It's a minor variation of
 the EP93xx reference design and in active use, while EP93xx apparently
 doesn't have enough new development to have any device tree support.

6ae52c65e0 ARM: SoC platform updates
In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
 C code changes for SoC platforms. This release cycle the diffstat is quite
 nice, in that we're removing 3x the amount of code that's being added.
 
 The main reason for this is that there's a removal of camera drivers for
 Freescale i.MX chips (driver was removed so the device registration isn't
 needed any more). There's also removal of display initialization code for OMAP
 that is no longer needed.
 
 The rest are mostly minor tweaks and cleanups; constification on Samsung
 platforms, cleanup of ux500 platform data, purge of other unused platform
 data/device seutp on i.MX and other good stuff.
 
 New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

b40881738f ARM: davinci: da850: fix da850_set_pll0rate()
This function is confusing - its second argument is an index to the
freq table, not the requested clock rate in Hz, but it's used as the
set_rate callback for the pll0 clock. It leads to an oops when the
caller doesn't know the internals and passes the rate in Hz as
argument instead of the cpufreq index since this argument isn't bounds
checked either.

Fix it by iterating over the array of supported frequencies and
selecting a one that matches or returning -EINVAL for unsupported
rates.

Also: update the davinci cpufreq driver. It's the only user of this
clock and currently it passes the cpufreq table index to
clk_set_rate(), which is confusing. Make it pass the requested clock
rate in Hz.

e79ab194d1 ARM: SoC platform updates for v4.10
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - Added support for the TI DRA71x family of SoCs in mach-omap2,
   this is an new variant of the the DRA72x/DRA74x automotive
   infotainment chips we already supported for a while.
 
 - Added support for the ST STM32F746 SoC, the first Cortex-M7
   based microcontroller we support, related to the smaller
   STM32F4 family.
 
 - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
   see http://elinux.org/RZ-G
 
 - SMP is now supported on the OX820 platform
 
 - A lot of code in mach-omap2 gets removed as a follow-up to
   removing support for board files in the previous release
 
 - Davinci has some new work to improve USB support
 
 - For i.MX, the performance monitor now supports profiling the
   memory controller using 'perf'
 
 Conflicts:
 arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init()
 is gone, calling of_clk_init(NULL) is sufficient now.

Pull ARM SoC platform updates from Arnd Bergmann:
 "These are updates for platform specific code on 32-bit ARM machines,
  essentially anything that can not (yet) be expressed using DT files.

  Noteworthy changes include:

   - Added support for the TI DRA71x family of SoCs in mach-omap2, this
     is an new variant of the the DRA72x/DRA74x automotive infotainment
     chips we already supported for a while.

   - Added support for the ST STM32F746 SoC, the first Cortex-M7 based
     microcontroller we support, related to the smaller STM32F4 family.

   - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see
     http://elinux.org/RZ-G

   - SMP is now supported on the OX820 platform

   - A lot of code in mach-omap2 gets removed as a follow-up to removing
     support for board files in the previous release

   - Davinci has some new work to improve USB support

   - For i.MX, the performance monitor now supports profiling the memory
     controller using 'perf'"

While the clk lookup table is making reference to "ohci"
other subsystems (such as phy) are trying to match "ohci.0"

Since there is a single ohci instance, instead of changing
the clk name, change the dev id to -1, and add the "-da8xx"
postfix to match the driver name that will also be changed
in a subsequent patch.

36173c2d02 ARM: davinci: da850: Fix pwm name matching
This fixes pwm name matching for DA850 familiy devices. When using device
tree, the da850_auxdata_lookup[] table caused pwm devices to have the exact
same name, which caused errors when trying to register the devices.

We cannot have multiple entries for the same clock in in da850_clks[], so
we have added child clocks to the EHRPWM and ECAP LPSC clocks so that each
PWM device will have its own clock for proper name matching.

8f899b4ed6 ARM: davinci: da850: Add ti-aemif lookup for clock matching
The davinci boards don't have their clocks in DT yet and getting a clock
will fail, unless registering them as clk_lookups. This registers the
aemif clock for the ti-aemif memory driver.

The current aemif lookup entry resolving to the same clock:
    'CLK(NULL,               "aemif",        &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward
compatibility.

Currently the davinci boards only configure the AEMIF in case of non-DT
boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via
the ti-aemif memory driver code.

The da850 family of processors has an async3 clock domain that can be
muxed to either pll0_sysclk2 or pll1_sysclk2. Now that the davinci clocks
have a set_parent callback, we can use this to control the async3 mux
instead of a stand-alone function.

This adds a new async3_clk and sets the appropriate child clocks. The
default is use to pll1_sysclk2 since it is not affected by processor
frequency scaling.
