Move hdmi_pll_compute(), used to calculate the config for HDMI PLL, from
hdmi_pll.c to pll.c, with the name of dss_pll_calc_b(), to make it
available to non-HDMI users.

To make it possible to use HDMI PLL for other video outputs than HDMI,
the HDMI PLL code needs to do runtime_get/put for the HDMI IP, so that
the IP (include the PLL) is enabled.
To do that we also need to store the HDMI pdev in the hdmi_pll_data.

DPI driver uses a fixed clkout index, 0. This has worked fine as the
first clkout is usually used.
To generalize the code and to support additional clock sources, change
the code to use dss_pll_get_clkout_idx_for_src() to get the clkout
index.

We can clean up the DPI driver's clock source handling by using the
dss_clk_source instead of only a dss_pll pointer.
This will also make it possible to use additional clock sources, like
PLL1_3 or HDMI_PLL, which the code did not support earlier.

Add two PLL helper functions:
dss_pll_find_by_src() which returns the dss_pll for the given
dss_clk_source.
dss_pll_get_clkout_idx_for_src() which returns the clkout index for the
given dss_clk_source.

The code to set the clock muxes for DISPC's LCD clock inputs is very
confusing. Especially on DRA7, there's an additional clock muxing that
needs to be done, which at the moment is done in dpi.c using
dss_ctrl_pll_set_control_mux().
Clean this all up by:
- Using dss_clk_source instead of dss_pll_id, as dss_pll_id doesn't
specify the clock source quite correctly.
- Splitting the dss_select_lcd_clk_source() up into DSS version specific
helper functions.
- Using dss_ctrl_pll_set_control_mux() from the helper functions, so
that dpi.c doesn't have to call it.

DSS uses two types of PLLs, type A (DSI & Video) and type B (HDMI). The
two types behave slightly differently, but we don't have the type of the
PLL available anywhere for the driver.
This patch adds an enum for the PLL type and a field in the PLL's HW
data to store it.

We have two functions to return a name for clock sources for debugging
purposes: dss_feat_get_clk_source_name() and
dss_get_generic_clk_source_name().
The former is supposed to return a DSS IP version specific name for the
clock source, and the latter is supposed to return a more generic name.
All this seems a bit pointless, so let's remove the former one.

Pull ARC updates from Vineet Gupta:
"We have a relatively big changeset for ARC for 4.7.
The highlight is support for EZChip (now Mellanox) NPS-400 network
processor, a 400-Gb throughput C-programmable packet processor based
on ARC700 cores from Synopsys. See
http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf
Also present are irqchip and clocksource drivers for NPS as agreed
with respective maintainers to go via ARC tree due to an soc header
dependency. I have the needed ACKs from Jason, Marc, Daniel. You
might run into a trivial merge conflict in drivers/irqchip/*
This EZChip platform support required some deep changes in ARC
architecture code and also opportunity to cleanup past sins (legacy
irq domains, missing irq domain lookup, hard coded timer irqs...)
Summary:
- Support for EZChip (now Mellanox) NPS-400 Network processor based
on ARC700
- NPS interrupt controller and clocksource drivers
- ARC timers probed off DT
- ARC iqrchips switching to linear domain (upgrade from legacy
domains)"

This patch adds binding information for IBM/AMCC/APM GPIO
Controllers of the PowerPC 4XX series and compatible SoCs.
The "PowerPC 405EP Embedded Processor Data Sheet" has the
following to say about the GPIO controllers: "
- Controller functions and GPIO registers are programmed
and accessed via memory-mapped OPB bus master accesses
- All GPIOs are pin-shared with other functions. DCRs control
whether a particular pin that has GPIO capabilities acts
as a GPIO or is used for another purpose.
- Each GPIO outputs is separately programmable to emulate
an open-drain driver (i.e. drives to zero, threestated if
output bit is 1)
"
The ppc4xx_gpio.c driver is part of the platform/sysdev drivers
in arch/powerpc/sysdev.

Function populate_node() is used to unflatten FDT blob to device
tree. It supports maximal 64 level of device nodes. There is one
array @fpsizes[64] tracking the full name length of last unflattened
device node in the corresponding level (index of element in the
array - 1). Build warning is seen with CONFIG_FRAME_WARN=1024 like
below on ARM64 as Geert reported. The issue can be reproduced on
PPC64 as well.
$ make drivers/of/fdt.o
drivers/of/fdt.c:443:1: warning: the frame size of 1136 bytes is \
larger than 1024 bytes [-Wframe-larger-than=]
This changes the data type of @fpsizes[i] from "unsigned long" to
"unsigned int" to avoid the build warning. The return value type
of populate_node() and its @fpsize argument is adjusted accordingly.
With this applied, 256 bytes saved from the stack frame on ARM64 and
PPC64 platforms and the above warning isn't seen.

When the implementation for unflatten_dt_node() changed from being
recursive to being non-recursive, it had a side effect of increasing the
depth passed to fdt_next_node() by 1. This is fine most of the time, but
it seems that when the end of the dtb is being parsed, it will cause the
FDT_END condition in fdt_next_node() to return a different value
(returning nextoffset instead of -FDT_ERR_NOTFOUND). This ends up passing
an FDT_ERR_TRUNCATED error back to the unflatten_dt_node() which then
sees that and complains "Error -8 processing FDT" causing boot to fail.
This patch simply avoids incrementing depth and uses modified accesses
for local array indices so that the depth is the same as it was before
the change as far as fdt_next_node() is concerned.
This problem was discovered trying to boot Tegra210-Smaug platforms.

On ARM64, the mtk-pmic-wrap driver causes a harmless warning:
mtk-pmic-wrap.c:1062:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1074:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
.int_en_all = ~(BIT(31) | BIT(1)),
The problem is that the result of the BIT() macro is an 'unsigned long',
so taking the bitwise NOT operation of that results in an integer
with the upper 32 bits all set and that cannot be assigned to a
'u32' variable without loss of information.
This is harmless because we were never interested in the upper bits
here anyway, so we can shut up the warning by adding a simple cast
to 'u32'.

Set plane_state->base.fence to the dma_buf exclusive fence,
and add a wait to the mmio function. This will make it easier
to unify plane updates later on.

With intel_pipe_update begin/end we ensure that the mmio updates
don't run during vblank interrupt, using the hw counter we can
be sure that when current vblank count != vblank count at the time
of pipe_update_end the mmio update is complete.
This allows us to use mmio updates on all platforms, using the
update_plane call.
With Chris Wilson's patch to skip waiting for vblanks for
legacy_cursor_update this potentially leaves a small race
condition, in which update_plane can be called with a freed
crtc_state. Because of this commit acf4e84d61673
("drm/i915: Avoid stalling on pending flips for legacy cursor updates")
is temporarily reverted.
Changes since v1:
- Split out the flip_work rename.

This reverts commit acf4e84d6167317ff21be5c03e1ea76ea5783701.
Unfortunately this breaks the next commit with a use-after-free, so
temporarily revert until we can apply a solution.

Rename intel_unpin_work to intel_flip_work and use it for mmio flips
and unpinning. Use flip_queued_req to hold the wait request in the
mmio case, and the vblank counter from intel_crtc_get_vblank_counter.
MMIO flips get their own path through intel_finish_page_flip_mmio,
handled on vblank. CS page flips go through *_cs.
Changes since v1:
- Clean up destinction between MMIO and CS flips.

This uses the newly created drm_accurate_vblank_count_and_time to accurately
get a vblank count when the hw counter is unavailable.

Instead of calling prepare_flip right before calling finish_page_flip
do everything from prepare_page_flip in finish_page_flip.
Putting prepare and finish page_flip in a single step removes the need
for INTEL_FLIP_COMPLETE, so it can be removed. This simplifies the code
slightly.
Changes since v1:
- Invert if case to simplify code.
- Add missing barrier.
- Reword commit message.
Changes since v2:
- intel_page_flip_plane is removed.
- work->pending is turned into a bool.
