f11bd978ab clk-gate: fix bit # check in clk_register_gate()
commit 2e9dcdae40 upstream.

In case CLK_GATE_HIWORD_MASK flag is passed to clk_register_gate(), the bit #
should be no higher than 15, however the corresponding check is obviously off-
by-one.

5fcb774872 clk: sunxi: Support factor clocks with N factor starting not from 0
commit 9a5e6c7eb5 upstream.

The PLLs on newer Allwinner SoC's, such as the A31 and A23, have a
N multiplier factor that starts from 1, not 0.

This patch adds an option to the factor clk driver's config data
structures to specify the base value of N.

c52b5661bd sunxi: clk: Set sun6i-pll1 n_start = 1
commit 76820fcf7a upstream.

For all pll-s on sun6i n == 0 means use a multiplier of 1, rather then 0 as
it means on sun4i / sun5i / sun7i. n_start = 1 is already correctly set
for sun6i pll6, but was missing for pll1, this commit fixes this.

dc2301c7ed clk: zynq: Force CPU_2X clock to be ungated
commit 3dccfecdb8 upstream.

The CPU_2X clock does not have a classical in-kernel user, but is,
amongst other things, required for OCM and debug access. Make sure this
clock is not mistakenly disabled during boot up by enabling it in the
platform's clock driver.

4a6c0a1ad6 clk: qcom: Fix MN frequency tables, parent map, and jpegd
commit ff20783f7b upstream.

Clocks that don't have a pre-divider don't list any pre-divider
in their frequency tables, but their tables are initialized using
aggregate initializers. Use tagged initializers so we properly
assign the m and n values for each frequency. Furthermore, the
mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second
element to pll2 instead of pll8, causing the clock driver to
recalculate the wrong rate for any clocks using this array along
with a rate that uses pll2. Plus the .num_parents field is 3
instead of 4 so you can't even switch the parent to pll3. Finally
I noticed that the jpegd clock improperly indicates that the
pre-divider width is only 2, when it's actually 4 bits wide.

ed7150a026 clk: prevent erronous parsing of children during rate change
commit 067bb1741c upstream.

In some cases, clocks can switch their parent with clk_set_rate, for
example clk_mux can do this in some cases. Current implementation of
clk_change_rate uses un-safe list iteration on the clock children, which
will cause wrong clocks to be parsed in case any of the clock children
change their parents during the change rate operation. Fixed by using
the safe list iterator instead.

The problem was detected due to some divide by zero errors generated
by clock init on dra7-evm board, see discussion under
http://article.gmane.org/gmane.linux.ports.arm.kernel/349180 for details.

22c9e299cc clk: s2mps11: Fix double free corruption during driver unbind
commit 2a96dfa49c upstream.

After unbinding the driver memory was corrupted by double free of
clk_lookup structure. This lead to OOPS when re-binding the driver
again.

The driver allocated memory for 'clk_lookup' with devm_kzalloc. During
driver removal this memory was freed twice: once by clkdev_drop() and
second by devm code.

2bf0e785c5 clk: Fix slab corruption in clk_unregister()
commit 874f224cc5 upstream.

When a clock is unregsitered, we iterate over the list of
children and reparent them to NULL (i.e. orphan list). While
iterating the list, we should use the safe iterators because the
children list for this clock is changing when we reparent the
children to NULL. Failure to iterate safely can lead to slab
corruption like this:

798ad2abc1 clk: Fix double free due to devm_clk_register()
commit 293ba3b4a4 upstream.

Now that clk_unregister() frees the struct clk we're
unregistering we'll free memory twice: first we'll call kfree()
in __clk_release() with an address kmalloc doesn't know about and
second we'll call kfree() in the devres layer. Remove the
allocation of struct clk in devm_clk_register() and let
clk_release() handle it. This fixes slab errors like:

1722226dab CLK: TI: OMAP4/5/DRA7: Remove gpmc_fck from dummy clocks
commit 8559087f0e upstream.

When arch/arm/mach-omap2/gpmc.c calls clk_get(..., "fck"), it will
get a dummy clock and try to use it. As the rate is configured to zero,
this will result in several divisions by zero, and misconfigured
timings, with devices on the bus being lost in the La La Land.

It is better to remove gpmc_fck from the dummy clocks, so that gpmc.c
can fail gracefully.

The Z clock frequency change is effective only after setting the kick

Without that, the CA15 CPUs clock rate will never change.

Fix that by checking if the kick bit is cleared and enable it to make

The Nomadik debugfs screws up multiplatform boots if debugfs

initcall that is unconditionally executed and reads from certain

Fix this by checking that the driver has been properly
initialized, so a base offset to the Nomadik SRC controller
exists, before proceeding to register debugfs files.

The host1x clock on Tegra124 is a 3-bit wide mux with 6 parents.
Change thte id to tegra_clk_host1x_8 so that the correct clock gets
registered.

PLLD was using the same mnp table as PLLP.  Fix it to use its own
table which is different from PLLP's.

2ec35fd503 clk: tegra: Fix PLLP rate table
This table had settings for 216MHz, but PLLP is (and is supposed to be)
configured at 408MHz.  If that table is used and PLLP_BASE_OVRRIDE is
not set, the kernel will panic in clk_pll_recalc_rate().

a65e0c6a7f clk: keystone: gate: fix clk_init_data initialization
The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.

Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.

So initialize flags in this structure too.

58d516ae95 clk: mvebu: kirkwood: maintain clock init order
Init order of CLK_OF_DECLARE'd drivers depends on compile order.
Unfortunately, clk_of_init does not allow drivers to return errors,
e.g. -EPROBE_DEFER if parent clocks have not been registered, yet.

To avoid init order woes for MVEBU clock drivers, we take care of
proper init order ourselves. This patch joins core-clk and gating-clk
init to maintain proper init order.

d30492adea The second half of the clock framework pull requeust for 3.14 is
dominated by platform support for Qualcomm's MSM SoCs, DT binding
 updates for TI's OMAP-ish processors and additional support for Samsung
 chips. Additionally there are other smaller clock driver changes and
 several last minute fixes. This pull request also includes the HiSilicon
 support that depends on the already-merged arm-soc pull request.

d1933689aa clk: sunxi: fix overflow when setting up divided factors
Currently, we are allocating space for two pointers, when we actually
may need to store three of them (two divisors plus the original clock).
Fix this, and change sizeof(type) to sizeof(*var) to keep checkpatch.pl
happy.
