ODROID-N2L is a variant SBC in small form factor and some peripherals
are removed from ODROID-N2PLUS based on S922X SoC.
- On-board ethernet is removed
- On-board RTC is removed
- USB 3.0 hub is removed, so one USB 2.0 and one USB 3.0 host ports
are available
- Huge heatsink is replaced with 40x40mm heatsink, 5V active heatsink
is recommended or a tall passive sink is optional
- 3.5mm earjack is removed
- IR remote receiver is removed
- MIPI DSI port is added new but not tested with upstream kernel yet

Two device tree overlays are added to support GPS PPS client through
GPIO pin header #11 and #12 as 'pps-gpio_p11.dtbo' and
'pps-gpio_p12.dtbo' respectively.

This device overlay patch is to set lower temperature that triggers
cooler fan at 45 degress celsius rather than 65 degrees celsius.

In general, the gpio-line-names property should belong to the node
whereby the gpio-controller property by the related document written.
But from now, at least for the Odroid boards based on AMLogic SoC,
the property has to be in the periphs_pinctrl node so that the
function for assigning the line names recognizes that.

Since commit 210f418f8a ("mfd: rk8xx: Add rk806 support"), devices are
registered with "0" as id, causing devices to not have an automatic device id
and prevents having multiple RK8xx PMICs on the same system.
Properly pass PLATFORM_DEVID_AUTO to devm_mfd_add_devices() and since
it will ignore the cells .id with this special value, also cleanup
by removing all now ignored cells .id values.
Now we have the same behaviour as before rk806 introduction and rk806
retains the intended behavior.
This fixes a regression while booting the Odroid Go Ultra on v6.6.1:

In order to setup the DSI clock, let's make the unused VCLK2 clock path
configuration via CCF.
The nocache option is removed from following clocks:
- vclk2_sel
- vclk2_input
- vclk2_div
- vclk2
- vclk_div1
- vclk2_div2_en
- vclk2_div4_en
- vclk2_div6_en
- vclk2_div12_en
- vclk2_div2
- vclk2_div4
- vclk2_div6
- vclk2_div12
- cts_encl_sel
vclk2 and vclk2_div uses the newly introduced vclk regmap driver
to handle the enable and reset bits.
In order to set a rate on cts_encl via the vclk2 clock path,
the NO_REPARENT flag is set on cts_encl_sel & vclk2_sel in order
to keep CCF from selection a parent.
The parents of cts_encl_sel & vclk2_sel are expected to be defined
in DT.
The following clock scheme is to be used for DSI:
xtal
\_ gp0_pll_dco
\_ gp0_pll
|- vclk2_sel
| \_ vclk2_input
| \_ vclk2_div
| \_ vclk2
| \_ vclk2_div1
| \_ cts_encl_sel
| \_ cts_encl -> to VPU LCD Encoder
|- mipi_dsi_pxclk_sel
\_ mipi_dsi_pxclk_div
\_ mipi_dsi_pxclk -> to DSI controller
The mipi_dsi_pxclk_div is set as RO in order to use the same GP0
for mipi_dsi_pxclk and vclk2_input.
