Anson Huang 7a5568ce08 ARM: imx: using unsigned variable for do_div
The definition of do_div uses unsigned long long
variable as its first parameter, better to pass
a u64 variable as first parameter when calling
do_div function.

Shawn Guo de8e434d09 ARM: imx: drop epit timer initialization from imx35 clock driver
EPIT provides another timer implementation besides the default GPT
timer.  The imx35 clock driver will use EPIT timer when option
CONFIG_MXC_USE_EPIT is enabled.  However, initializing timers from
clock driver is a workaround solution and causes problem when we move
clock drivers into driver/clk.

Let's simply drop the EPIT initialization from there.  If people really
want this EPIT option, EPIT timer driver needs to be reworked to do the
initialization in a standard way - use CLOCKSOURCE_OF_DECLARE() with
device tree support.

Hans de Goede ec80749dfd clk: sunxi: Add support for the usb-clk on sun8i a23 and a33 SoCs
The usb-clk on sun8i a23 and a33 SoCs is similar to the ones found
on sun6i-a31 SoCs but instead of a 3th phy the a23 / a33 have a hsic
interface which gets enabled by almost the same bits as used on
the a31 for the 3rd phy, but not exactly the same bits so we need
a new compatible for this.

Krzysztof Kozlowski e0cdcda508 clk: ti: dra7-atl-clock: Fix possible ERR_PTR dereference
of_clk_get_from_provider() returns ERR_PTR on failure. The
dra7-atl-clock driver was not checking its return value and
immediately used it in __clk_get_hw().  __clk_get_hw()

Robert Jarzmik 5e1d012851 ARM: pxa: change clocks init sequence
Since pxa clocks were ported to the clock framework, an ordering issue
appears between clocks and clocksource initialization. As a consequence,
the pxa timer clock cannot be acquired in pxa_timer, and is disabled by
clock framework because it is "unused".

The ordering issue is that in the kernel boot sequence :
  start_kernel()
    ...
    time_init()
      -> pxa_timer()
        -> here the clocksource is initialized
    ...
    rest_init()
      kernel_init()
	initcalls
	  -> here the clocks are initialized

In the current sequence, the clocks are initialized way after pxa_timer,
which cannot acquire the OSTIMER0 clock.

To solve this issue, the clocks initialization is moved to pxa_timer(),
so that clocks are initialized before clocksource for non device-tree.
For device-tree, the standard arm time_init() will take care of the
ordering.

Russell King d5622a9c13 clkdev: use clk_hw internally
clk_add_alias() calls clk_get() followed by clk_put() but in between
those two calls it saves away the struct clk pointer to a clk_lookup
structure. This leaves the 'clk' member of the clk_lookup pointing at
freed memory on configurations where CONFIG_COMMON_CLK=y. This is a
problem because clk_get_sys() will eventually try to dereference the
freed pointer by calling __clk_get_hw() on it. Fix this by saving away
the struct clk_hw pointer instead of the struct clk pointer so that when
we try to create a per-user struct clk in clk_get_sys() we don't
dereference a junk pointer.

Commit ae43b32891 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power

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.

Stephen Boyd d6968fca78 clk: s/clk/core/ for struct clk_core
While introducing struct clk_core we tried to minimize the diff
by changing the type of 'clk' variables from struct clk to struct
clk_core without changing the names of the variables. Now that
the split is complete, the code is slightly confusing when it
mixes variables called 'clk' and variables called 'core' that are
of the same type struct clk_core. Let's be consistent and use
'core' everywhere we have a struct clk_core pointer and 'clk'
when we have a struct clk pointer.

The statement

	static const char *name[];

defines a modifiable array of pointers to constant chars. That is

	*name[0] = 'f';

is forbidden, but

	name[0] = "f";

is not. So marking an array that is defined as above with __initconst is
wrong. Either an additional const must be added such that the whole
definition reads:

	static const char *const name[] __initconst;

or where this is not possible __initdata must be used.

Philipp Zabel 9a74ccdbbb clk: Add PWM clock driver
Some board designers, when running out of clock output pads, decide to
(mis)use PWM output pads to provide a clock to external components.
This driver supports this practice by providing an adapter between the
PWM and clock bindings in the device tree. As the PWM bindings specify
the period in the device tree, this is a fixed clock.

Robert Jarzmik c7739aebec clk: pxa: pxa3xx: add missing os timer clock
The pxa3xx scheduler relies on the pxa-timer, which requires a clock for
its rate. As the clock handling will be taken over by the clock
framework, add this missing clock.

The miss was discovered by attempting to run a zylonite platform in a
device-tree configuration, with the future patch to shift clocks
handling to clock framework applied.

Thierry Reding a84724a1c3 clk: tegra: Use generic tegra_osc_clk_init() on Tegra114
There is no reason why Tegra114 cannot use the same generic code to set
up the oscillator, clk_m and pll_ref clocks. The only effective change
that this causes is that the CLK_SET_PARENT_RATE flag is dropped, but
since these clocks are all fixed it is not needed anyway.

Thierry Reding 63cc5a4da1 clk: tegra: Model oscillator as clock
Currently the Tegra clock driver simplifies the clock tree somewhat by
taking advantage of the fact that clk_m runs at the same frequency as
the oscillator. While that's true on all currently supported SoCs, it
does not apply to Tegra210 anymore. On Tegra210 clk_m is typically
divided down from the oscillator frequency. To support that setup, add
a separate clock for the oscillator that both clk_m and pll_ref derive
from.

Modify the tegra_osc_clk_init() function to take an additional divider
parameter for clk_m. Existing SoCs always pass in 1, whereas Tegra210
will read the divider from a register in the clock & reset controller.

Thierry Reding 5e43e25917 clk: tegra: Register the proper number of resets
The number of resets controls is 32 times the number of peripheral
register banks rather than 32 times the number of clocks. This reduces
(drastically) the number of reset controls registered from 10080 (315
clocks * 32) to 224 (6 peripheral register banks * 32).

This also fixes a potential crash because trying to use any of the
excess reset controls (224-10079) would have caused accesses beyond
the array bounds of the peripheral register banks definition array.

as the last clock output of the clock node. This makes it rather difficult
to add new outputs, such as fixed dividers, which were previously unknown.

This patch makes the divs clocks data structure specify which output is
the factor clock, and updates all current divs clocks accordingly.

We can then add new outputs after the factor clocks, at least not breaking
backward compatibility with regards to the devicetree bindings.

Also replace kzalloc with kcalloc in sunxi_divs_clk_setup().

Tony Lindgren 9089848d9a clk: ti: Implement FAPLL set_rate for the PLL
Since we have a fractional divider for the synthesizer, just implement
a simple multiply logic for the PLL.

It seems the PLL divider needs to have also the multiplier set for the PLL
to lock. At least I have not yet figured out if divided rates are doable.

So let's just ignore the PLL divider for now as the synthesizer has both
integer and fractional dividers so we don't even need to use the PLL
divider for the rates we know work with PLL locking.

Suman Anna 712f7d64f0 clk: ti: DRA7: Add timer_sys_ck aliases for Timers 13 through 16
The OMAP DMTimer API, omap_dm_timer_set_source(), uses the clock name
timer_sys_ck for setting a timer's clock source for the source index
OMAP_TIMER_SRC_SYS_CLK. There is currently no clock alias data for
the Timers 13 through 16 for this clock name, so add the same.

Suman Anna d4295be387 clk: ti: DRA7: Correct timer_sys_ck clock aliases for Timers
The OMAP DMTimer API, omap_dm_timer_set_source(), can set the parent
of a timer node using 3 different values that use fixed parent names
for the clocks. The parent name, timer_sys_ck, is used for setting the
parent when used with the source index OMAP_TIMER_SRC_SYS_CLK. This
should point to the TIMER_SYS_CLK and not the SYSCLKIN2, so correct
the clock aliases appropriately. SYSCLKIN2 is not a mandatory clock
input.

Suman Anna 03ff41a938 clk: ti: OMAP5: Correct the DT clock aliases for timers
The DT clock aliases for Timers use the legacy (non-DT) device
names and a source clock named sys_ck. OMAP5 is DT-boot only,
so correct the DT clock aliases to use the DT device names
instead. Also, the source clock name is corrected from 'sys_ck'
to 'timer_sys_ck', the name used by the OMAP dmtimer driver.

Suman Anna 2ff8d75c23 clk: ti: OMAP4: Remove the legacy timer DT clock aliases
The DT clock aliases for timers using the legacy OMAP timer
device names have been cleaned up. These device names reflect
the names used in legacy boot, and are no longer applicable
as OMAP4 is DT boot only now.

Peter Ujfalusi c8d3829212 clk: ti: clk-3xxx-legacy: Correct McBSP related clock aliases
Correct the McBSP2/4 ick mapping (they were 2->4 and 4->2).
Add missing mcbsp clock aliases.
Collect the McBSP clock definition in one location at the same time.

Fixes the following warning on boot:
[    0.307739] omap_hwmod: mcbsp2: _wait_target_ready failed: -16
[    0.307769] omap_hwmod: mcbsp2: cannot be enabled for reset (3)
