CLK_NR_CLKS should not be part of the binding. Let's drop it, since
the kernel code no longer uses it either.

CLK_NR_CLKS is not part of the DT bindings and needs to be removed
from it, just like it recently happened for other platforms. This
takes care of it by introducing a new function identifying the
maximum used clock ID at runtime.

The sdmmc node already have a "&sdmmc_det" for pinctrl which switch the
GPIO0A4 to sdmmc detect function, no need to define a separate "cd-gpios".
RK3588 has force_jtage feature which is enable JTAG function via sdmmc
pins automatically when there is no SD card insert, this feature will
need the GPIO0A4 works in sdmmc_det function like other mmc signal instead
of GPIO function, or else the force_jtag can not auto be disabled when
SD card insert.

A hardware switch can set the rs485 transceiver into half or full duplex
mode.
Switching to the half-duplex mode requires the user to enable em485 on
uart5 using ioctl, DE/RE are both connected to GPIO0_B5 which is the
RTS signal for uart0. Implement GPIO0_B5 as rts-gpios with RTS_ON_SEND
option enabled (default) so that driver mode gets enabled while sending
(RTS high) and receiver mode gets enabled while not sending (RTS low).
In full-duplex mode (em485 is disabled), DE is connected to GPIO0_B5 and
RE is grounded (enabled). Since GPIO0_B5 is implemented as rts-gpios, the
driver mode gets enabled whenever we want to send something and RE is not
affected (always enabled) in this case by the state of RTS.

Move the vdd_cpu regulator to the device specific dts. This is in
preparation of adding the Powkiddy RGB10MAX3 device, which uses
a different vendor for the CPU regulator at a different i2c address.
Also add a phandle to the bluetooth device so that we can change the
compatible string for the RGB10MAX3. This device uses the same pinouts
but a different bluetooth device.

There are 6 SPI controllers on RK3399 and they are all numbered in the
TRM, so let's add the appropriate aliases to the main DTSI so that any
RK3399-based board doesn't need to define the aliases themselves to
benefit from stable SPI indices in userspace.

Add missing cache information to the Rockchip RK3399 SoC dtsi. The specified
values were derived by hand from the cache size specifications available from
the RK3399 datasheet; for future reference, here's a brief summary:
- Each Cortex-A72 core has 48 KB of L1 instruction cache and
32 KB of L1 data cache available, four-way set associative
- Each Cortex-A53 core core has 32 KB of instruction cache and
32 KB of L1 data cache available, four-way set associative
- The big (A72) cluster has 1 MB of unified L2 cache available
- The little (A53) cluster has 512 KB of unified L2 cache available
This patch allows /proc/cpuinfo and lscpu(1) to display proper RK3399 cache
information, and it eliminates the following error in the kernel log:
cacheinfo: Unable to detect cache hierarchy for CPU 0
While there, add a couple of somewhat useful comments, which may help a bit
anyone going through the RK3399 SoC dtsi.
