i2c1 and i2c2 bits for CCU are not bit 0 but bit 1 and bit 2.
Because of that, the i2c0 (bit 0) was not correctly configured.

Fix child node-lookup during probe, which ended up searching the whole
device tree depth-first starting at parent rather than just matching on
its children.
Note that the original premature free of the parent node has already
been fixed separately, but that fix was apparently never backported to
stable.

Requesting the GPIOD_OUT_LOW low will make sure the GPIO is
deasserted when requested. The gpiolib core will make sure that
if the GPIO line is active low, it will be logically driven high
when deasserted, see drivers/gpiolib.c gpiod_configure_flags().

After som grep:ing it turns out nothing in the kernel is really calling
clk_[hw_]_register_gpio_[gate|mux](). All existing instances are just
created directly from the device tree probe functions at the bottom of
the clk-gpio.c clock provider file.
This means we can change the signature of the function without any
consequences! Everyone should be using GPIO descriptors now, so let's
just go in and enforce that.
This saves a bit of code since GPIO descriptors know inherently if they
are active low so no need for the code keeping track of that.
We leave it to the caller to come up with the GPIO descriptor. It is
nowadays possible to do that even without a corresponding device, so
no excuse not to pass them around. The one in-kernel user lifecycles
it using devm_gpiod_get() in gpio_clk_driver_probe().

On gcc-4.6, we get a harmless link-time warning:
WARNING: vmlinux.o(.text.unlikely+0x196a0): Section mismatch in reference from the function mtk_infrasys_init_early() to the function .init.text:mtk_clk_register_cpumuxes()
The function mtk_infrasys_init_early() references
the function __init mtk_clk_register_cpumuxes().
This is often because mtk_infrasys_init_early lacks a __init
annotation or the annotation of mtk_clk_register_cpumuxes is wrong.
Newer compilers inline this function so they don't warn, but
marking it __init is the right solution for all versions.

Allowing the lcdif_pre_sel to propagate rate changes to its parent PLL
allows more fine grained control over the LCDIF pixel clock rate.
For example, the Innovision AT043TN24 LCD panel described in the
imx6ul-14x14-evk device tree requires a 9 MHz pixel clock.
Before this patch, the lcdif_pre_sel clock rate is fixed, and just
setting the lcdif_pred and lcdif_podf dividers only allows to get as
close as about 8.44 MHz:
pll3 1 1 480000000 0 0
pll3_bypass 1 1 480000000 0 0
pll3_usb_otg 1 1 480000000 0 0
pll3_pfd1_540m 1 1 540000000 0 0
lcdif_pre_sel 1 1 540000000 0 0
lcdif_pred 1 1 67500000 0 0
lcdif_podf 1 1 8437500 0 0
lcdif_pix 1 1 8437500 0 0
Once lcdif_pre_sel is allowed to propagate rate requests to its parent,
the actual pixel clock matches the requested value:
pll3 1 1 480000000 0 0
pll3_bypass 1 1 480000000 0 0
pll3_usb_otg 1 1 480000000 0 0
pll3_pfd1_540m 1 1 288000000 0 0
lcdif_pre_sel 1 1 288000000 0 0
lcdif_pred 1 1 36000000 0 0
lcdif_podf 1 1 9000000 0 0

On i.MX6 SoCs without VPU (in my case MCIMX6D4AVT10AC), the hdmi driver
fails to probe:
[ 2.540030] dwhdmi-imx 120000.hdmi: Unsupported HDMI controller
(0000:00:00)
[ 2.548199] imx-drm display-subsystem: failed to bind 120000.hdmi
(ops dw_hdmi_imx_ops): -19
[ 2.557403] imx-drm display-subsystem: master bind failed: -19
That's because hdmi_isfr's parent, video_27m, is not correctly ungated.
As explained in commit 5ccc248cc537 ("ARM: imx6q: clk: Add support for
mipi_core_cfg clock as a shared clock gate"), video_27m is gated by
CCM_CCGR3[CG8].
On i.MX6 SoCs with VPU, the hdmi is working thanks to the
CCM_CMEOR[mod_en_ov_vpu] bit which makes the video_27m ungated whatever
is in CCM_CCGR3[CG8]. The issue can be reproduced by setting
CCMEOR[mod_en_ov_vpu] to 0.
Make the HDMI work in every case by setting hdmi_isfr's parent to
mipi_core_cfg.

The RPM clocks were missing for MSM8660/APQ8060. For this to be
completed we need to add a special fixed rate RPM clock that is used
for the PLL4 on these SoCs. The rest of the clocks are pretty
similar to the other supported platforms.
The "active" clock pattern is mirrored in all the clocks. I guess
that the PLL4 that clocks the LPASS is actually never used as
"active only" since the low-power audio subsystem should be left
on when the CPU goes to idle, so that it can be used as a stand-alone
MP3 player type of device.
The PLL4 seems to be enabled only on behalf of the booting LPASS
Hexagon - which will cast its own vote once its booted - and as
such we only configure the active state (meaning both states will
have same configuration). The result is that PLL4 will be on
from prepare() to unprepare() regardless of what the application
CPU does.

By default, it is assumed that the UTMI clock is generated from a 12 MHz
reference clock (MAINCK). If it's not the case, the FREQ field of the
SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the
proper way.
The UTMI clock has a fixed rate of 480 MHz. In fact, there is no
multiplier we can configure. The multiplier is managed internally,
depending on the reference clock frequency, to achieve the target of
480 MHz.
