The charger led definition ported from imx_4.9.y use the same gpio with
another definition introduced by upstream commit 702bfbef1c98 ("ARM:
dts: imx6qdl-sabresd.dtsi: Add red led")
Fix by explicitly overwriting the upstream definition with ours.
Fixes: 491c8dc6801e ("MLK-11703-6: ARM: imx6: Add charging led support on Sabresd board")
Fixes: 4aada993e5be ("MLK-11703-7: ARM: dts: imx6qdl-sabresd: add retain-state-suspended property in dts")
This commit could be squashed in the above on next rebase.

In imx6qdl-sabresd.dtsi imx_4.9.y defines ov564x_mipi@3c with
compatible="ovti,ov564x_mipi". Upstream added camera@3c with
compatible="ovti,ov5640" on the same bus and this results in i2c errors
on boot:
i2c i2c-1: Failed to register i2c client ov564x_mipi at 0x3c (-16)
i2c i2c-1: of_i2c: Failure registering /soc/aips-bus@02100000/i2c@021a4000/ov564x_mipi@3c
i2c i2c-1: Failed to create I2C device for /soc/aips-bus@02100000/i2c@021a4000/ov564x_mipi@3c
Fix by removing upstream definition.
The other camera camera added by upstream, &ov5642: camera@3c on &i2c0
was already removed/overwritten with our definition during porting.

The mxc display driver framework doesn't support deferral probe.
The following initialization process may cause the mipi dsi driver
deferral probe, however.
pinctrl-imx6 - arch_initcall
gpio-mxc - subsys_initcall
gpio-reset - arch_initcall
This patch customizes gpio reset function so that we can remove
the code to use the reset logic provided by the gpio-reset driver.
Also, the gpio-reset driver is not in the upstreaming kernel,
so it would be good not to use it if possible.

There is noise when use ssi master mode. the reason is the ssi rate
is not accurate for ssi master mode, show below.
pll3_pfd2_508m 0 0 508235294 0 0
ssi3_sel 0 0 508235294 0 0
ssi3_pred 0 0 127058824 0 0
ssi3_podf 0 0 63529412 0 0
ssi3 0 0 63529412 0 0
ssi2_sel 0 0 508235294 0 0
ssi2_pred 0 0 127058824 0 0
ssi2_podf 0 0 63529412 0 0
ssi2 0 0 63529412 0 0
so we need to switch ssi's parent to pll4 (which is dedicate audio pll),
and set a proper rate for pll4, we select 786432000Hz, which can
generate 32kHz,48kHz,96KHz.

The i.MX6Quad Plus processor is an high performance SOC of i.MX6 family.
It has enhanced graphics performance and increased overall memory bandwidth
compared to i.MX6Q. Most of the design are same as i.MX6Quad/Dual, so code
for i.MX6Quad can be resued by this chip. The revision number is identied as

Pull ARM DT updates from Olof Johansson:
"Ladies and gentlemen, we proudly announce to you the latest branch of
ARM device tree contents for the mainline kernel. Come and see, come
and see!
No less than twentythree thousand lines of additions! Just imagine the
joy you will have of using your mainline kernel on newly supported
hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
UniPhier hardware!
For those of you feeling less adventurous, added hardware support on
platforms such as TI DM814x and Gumstix Overo platforms might be more
of your liking.
We've got something for everyone here!
Ahem. Cough. So, anyway...
This is the usual large batch of DT updates. Lots and lots of smaller
changes, some of the larger ones to point out are:
- Rockchip veyron (Chromebook) support, as well as several other new boards
- DRM support on Atmel AT91SAM9N12EK
- USB additions on some Allwinner platforms
- Mediatek MT6580 support
- Freescale i.MX6UL support
- cleanups for Renesas shmobile platforms
- lots of added devices on LPC18xx
- lots of added devices and boards on UniPhier
There's also some dependent code added here, in particular some
branches that are primarily merged through the clock tree"

Currently it is not possible to have HDMI and LVDS working simultaneously,
because both ports try to use PLL5.
Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
driven from independent sources.
With this change the LDB pixel clock goes to 68.57 MHz, which is still
within the valid range for the HSD100PXN1 LVDS panel.
