For some platforms such as Qualcomm we need to wait for the
UART to be ready before writing characters to the UART
in the same manner as the macro in debug.S used with the
main "Uncompressing Linux ..." text. Pass an extra temporary
variable to writeb and make it call waituarttxrdy and
busyuart just like the other decomression messages.
Optionally it will also call waituartcts if and only if
CONFIG_DEBUG_UART_FLOW_CONTROL is selected.
After this the decompression debug messages work fine on
Qualcomm platforms if you compile head.S with -DDEBUG.

Instead of a flow control selection mechanism specifically for
8250, make this available for all debug UARTs. If the debug
UART supports waiting for CTS to be asserted, then this code
can be activated for terminals that need it.
We keep the defaults for EBSA110, Footbridge, Gemini and RPC
so that this still works as expected for these older platforms:
they assume that flow control shall be enabled for debug
prints.
I switch the location of the check for
ifdef CONFIG_DEBUG_UART_FLOW_CONTROL from the actual debug
UART drivers: the code would get compiled-out for 8250 and
Tegra unless their custom config (or passing -DFLOW_CONTROL
in the Tegra case) was not set. Instead this is conditional
at the three places where we print debug messages. The idea
is that debug UARTs can be implemented without this ifdef
boilerplate so they look cleaner, alas the ifdef has to be
somewhere.

This patch was triggered by a remark from Russell that
introducing a call to the waituart (needed to fix debug prints
on the Qualcomm platforms) was dangerous because in some cases
this will involve waiting for a modem CTS (clear to send)
signal, and debug messages would maybe not work on platforms
with no modem connected to the UART port: they will just
hang waiting for the modem to assert CTS and this might never
happen.
Looking through all UART debug drivers implementing the waituart
macro I discovered that all users except two actually use this
macro to check if the UART is ready for TX, let's call this
TXRDY.
Only two debug UART drivers actually check for CTS:
- arch/arm/include/debug/8250.S
- arch/arm/include/debug/tegra.S
The former is very significant since the 8250 is possibly
the most common UART on the planet.
We have the following problem: the semantics of waituart are
ambiguous making it dangerous to introduce the macro to debug
code fixing debug prints for Qualcomm. To start to pry this
problem apart, this patch does the following:
- Convert all debug UART drivers to define two macros:
- waituartcts with the clear semantic to wait for CTS
to be asserted
- waituarttxrdy with the clear semantic to wait for the TX
capability of the UART to be ready
- When doing this take care to assign the right function to
each drivers macro, so they now do exactly the above.
- Update the three sites in the kernel invoking the waituart
macro to call waituartcts/waituarttxrdy in sequence, so that
the functional impact on the kernel should be zero.
After this we can start to change the code sites using this
code to do the right thing.

The debug macros debug_reloc_start and debug_reloc_end were
rendered unused in commit 6d7d0ae51574943bf571d269da3243257a2d15db
"ARM: 6750/1: improvements to compressed/head.S".
Later on a different debug macro named dbgkc was introduced
in commit f3c899927e19d1be39818145efc39ea27b8efc69
"ARM: 8786/1: Debug kernel copy by printing".

The SP805 DT binding requires two clocks to be specified, but
Hisilicon platform DTs currently only specify one clock.
In practice, Linux would pick a clock named "apb_pclk" for the bus
clock, and the Linux and U-Boot SP805 driver would use the first clock
to derive the actual watchdog counter frequency.
Since currently both are the very same clock, we can just double the
clock reference, and add the correct clock-names, to match the binding.

The SP804 binding only specifies one or three clocks, but does not allow
just two clocks.
The HiSi 3620 .dtsi specified two clocks for the two timers, plus gave
one "apb_pclk" clock-name to appease the primecell bus driver.
Extend the clocks by duplicating the first clock to the end of the clock
list, and add two dummy clock-names to make the primecell driver happy.
I don't know what the real APB clock for the IP is, but with the current
DT the first timer clock was used for that, so this change keeps the
current status.

This pull request contains Broadcom ARM-based SoCs changes for 5.10,
please pull the following:
- Christian adds support for the Cisco Meraki MR32 which is based on the
BCM53016 SoC, this requires specifying the PWM, second UART and third
PCIe controller in Device Tree before finally adding support for the
board.
- Adrian updates the status properties from "ok" to "okay".
- Andre fixes the SP805 watchdog nodes to have the correct clock names
and binding for both the Cygnus and Northstar Plus (NSP). He does the
same thing with the SP804 timer node which was missing an
"arm,primecell" compatible string.
- Maxime enables the BCM2711 (Raspberry Pi 4) display pipeline since all
DRM changes are ready.

Using full paths to extend or override a device tree node is error
prone. If there was a typo error, a new node will be created instead of
extending the existing node. This will lead to run-time errors that
could be hard to detect.

(during build time).

string.
Add this string so that the Linux primecell bus driver picks the device
up and activates the clock.

The SP805 binding sets the name for the actual watchdog clock to
"wdog_clk" (with an underscore).
Change the name in the DTs for the Broadcom NSP platform to match that.
The Linux and U-Boot driver use the *first* clock for this purpose
anyway, so it does not break anything.

The SP805 DT binding requires two clocks to be specified, but the
Broadcom Cygnus DT currently only specifies one clock.
In practice, Linux would pick a clock named "apb_pclk" for the bus
clock, and the Linux and U-Boot SP805 driver would use the first clock
to derive the actual watchdog counter frequency.
Since currently both are the very same clock, we can just double the
clock reference, and add the correct clock-names, to match the binding.

already.

SERIAL:
WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
The Serial setting is 115200-8-N-1. The board has a populated
right angle 1x4 0.1" pinheader.
The pinout is: VCC, RX, TX, GND.
Odd stuff:
- uart0 clock frequency is 62.5 MHz.
- The LEDs are labeled as SYS-LED1 through SYS-LED3
because of the silkscreen on the PCB.
- the original u-boot has been compiled with most functions
and commands disabled. The u-boot env isn't setup properly
either and as a result, the bcm47xxpart probing is not
working. Hence, the nand partitions are specified through a
"fixed-partition" binding.
- The "WICED SMART(TM)" Bluetooth LE 4.0 BCM20732 chip is
connected to uart2 of the SoC. The BCM20732 does not
provide a HCI. So the linux' bluetooth stack is useless.
The mock-up node with the compatible binding and
enable-gpios property is provided solely as documentation.

Documentation/devicetree/bindings/net/dsa/dsa.txt says that the phy-mode
property should be specified on port nodes. However, the microchip
drivers read it from the switch node.
Let the driver use the per-port property and fall back to the old
location with a warning.
Fix in-tree users.
