Hi,
this series aims to make it possible to validate NS 8250 compatible serial port
nodes in Device Tree. It ultimately ends up converting the 8250.txt binding
specification to YAML for json-schema.
It starts by fixing up a couple of issues that would fail validation of
device trees for various boards. Note there might be validation issues in other
boards -- I don't have computing power to run "make dtbs_check" with
CONFIG_OF_ALL_DTBS=y at the moment. I'm happy to fix up issues if somebody
runs the test output to me.
Unless someone has a different idea, I'd like to submit this to arm-soc once
I get the Acks from PXA and Tango maintainers as well as DT reviewers:
[PATCH 01/10] ARM: dts: pxa*: Don't redeclare phandle references
[PATCH 02/10] ARM: dts: pxa*: Fix serial port names
[PATCH 03/10] ARM: dts: pxa*: Make the serial ports compatible with
[PATCH 04/10] ARM: dts: mmp2-brownstone: Don't redeclare phandle
[PATCH 05/10] ARM: dts: mmp*: Fix serial port names
[PATCH 06/10] ARM: dts: mmp*: Make the serial ports compatible with
[PATCH 07/10] ARM: dts: tango4: Make /serial compatible with ns16550a
What follows is a large yet straightforward fixup of similar nature for PowerPC.
I'd be thankful if PowerPC maintainers could pick this patch up.
[PATCH 08/10] powerpc/fsl: Make serial ports compatible with ns16550a
Then follows folding of mrvl-serial.txt into 8250.txt (the Marvell serial
port is in fact an XScale UART, a variation of 8250) and the actual
conversion. Perhaps the best route these patches could take via the tty
tree.
[PATCH 09/10] dt-bindings: serial: Move Marvell compatible string to
[PATCH 10/10] dt-bindings: serial: Convert 8250 to json-schema
Thanks,
Lubo

Extend the nodes by their phandle references instead of recreating the
tree and declaring references of the same names.

There's a preferred node name for serial ports, and it's not "uart":
pxa910-dkb.dt.yaml: uart@d4017000: $nodename:0: 'uart@d4017000'
does not match '^serial(@[0-9a-f,]+)*$'

Some drivers that claim to support mrvl,mmp-uart default to a reg-shift
of two, some don't. Be explicit to be on a safe side.
With that in place, a XScale serial port driver is perfectly capable of
supporting the MMP serial port. Add a compatible string.

Extend the nodes by their phandle references instead of recreating the
tree and declaring references of the same names.

does not match '^serial(@[0-9a-f,]+)*$'

XScale serial port driver is perfectly capable of supporting this hardware. A
separate compatible string is probably a historical mess.

ralink,rt2880-uart is compatible with ns16550a and all other
instances of RT2880 UART nodes include it in the compatible property.
Add it also here, to make the binding schema simpler.

Lubomir Rintel
There are separate compatible strings for ns16550 and ns16550a and the
Freescale serial port is compatible with the latter one, with working
FIFO.
Use the appropriate compatible string that is also consistent with ARM64
Freescale boards and thus avoiding one special case in the binding schema.

These ports are compatible with NS8250 and handled by the same driver.
Get rid of the extra document that fails to document the properties that
are actually supported.

Some fixes were done during the conversion:
Slightly better examples. The original example was for an OMAP serial
port, which is not even described by this binding, but by
omap_serial.txt instead.
Added compatible strings, that were used, byt not documented:
andestech,uart16550, cavium,octeon-3860-uart, fsl,16550-FIFO64,
nvidia,tegra186-uart, nvidia,tegra194-uart, nxp,lpc1850-uart,
opencores,uart16550-rtlsvn105, ralink,mt7620a-uart, ralink,rt3052-uart,
ralink,rt3883-uart and xlnx,xps-uart16550-2.00.b.
Removed "serial" compatible string. It's redundant with the node name
(which, in OFW, serves the same purpose as the compatible string).

-- reg : offset and length of the register set for the device.
-- interrupts : should contain uart interrupt.
-- clock-frequency : the input clock frequency for the UART
- or
- clocks phandle to refer to the clk used as per Documentation/devicetree
- /bindings/clock/clock-bindings.txt
-
-Optional properties:
-- current-speed : the current active speed of the UART.
-- reg-offset : offset to apply to the mapbase from the start of the registers.
-- reg-shift : quantity to shift the register offsets by.
-- reg-io-width : the size (in bytes) of the IO accesses that should be
- performed on the device. There are some systems that require 32-bit
- accesses to the UART (e.g. TI davinci).
-- used-by-rtas : set to indicate that the port is in use by the OpenFirmware
- RTAS and should not be registered.
-- no-loopback-test: set to indicate that the port does not implements loopback
- test mode
-- fifo-size: the fifo size of the UART.
-- auto-flow-control: one way to enable automatic flow control support. The
- driver is allowed to detect support for the capability even without this
- property.
-- tx-threshold: Specify the TX FIFO low water indication for parts with
- programmable TX FIFO thresholds.
-- resets : phandle + reset specifier pairs
-- overrun-throttle-ms : how long to pause uart rx when input overrun is encountered.
-- {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
- line respectively. It will use specified GPIO instead of the peripheral
- function pin for the UART feature. If unsure, don't specify this property.
-- aspeed,sirq-polarity-sense: Only applicable to aspeed,ast2500-vuart.
- phandle to aspeed,ast2500-scu compatible syscon alongside register offset
- and bit number to identify how the SIRQ polarity should be configured.
- One possible data source is the LPC/eSPI mode bit.
- Example: aspeed,sirq-polarity-sense = <&syscon 0x70 25>
-
-Note:
-* fsl,ns16550:
- ------------
- Freescale DUART is very similar to the PC16552D (and to a
- pair of NS16550A), albeit with some nonstandard behavior such as
- erratum A-004737 (relating to incorrect BRK handling).
-
- Represents a single port that is compatible with the DUART found
- on many Freescale chips (examples include mpc8349, mpc8548,
- mpc8641d, p4080 and ls2085a).
-
-Example:
-
- uart@80230000 {
- compatible = "ns8250";
- reg = <0x80230000 0x100>;
- clock-frequency = <3686400>;
- interrupts = <10>;
- reg-shift = <2>;
- };
-
-Example for OMAP UART using GPIO-based modem control signals:
-
- uart4: serial@49042000 {
- compatible = "ti,omap3-uart";
- reg = <0x49042000 0x400>;
- interrupts = <80>;
- ti,hwmods = "uart4";
- clock-frequency = <48000000>;
- cts-gpios = <&gpio3 5 GPIO_ACTIVE_LOW>;
- rts-gpios = <&gpio3 6 GPIO_ACTIVE_LOW>;
- dtr-gpios = <&gpio1 12 GPIO_ACTIVE_LOW>;
- dsr-gpios = <&gpio1 13 GPIO_ACTIVE_LOW>;
- dcd-gpios = <&gpio1 14 GPIO_ACTIVE_LOW>;
- rng-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;

I don't think changing this is right. First, 'ns16550' is what's
documented in the DT spec (and ePAPR which it's based on).
Second, these dts files are pretty mature/stable, so I'm less inclined
to change them. AFAICT, this change either enables the fifo (which
would be an untested change in behavior) or has no effect because the
fifo is auto-detected.

Well, that's annoying...

Yeah, that seems fairly useless to me.

Seems to me these are just as likely to be wrong as the fsl,ns16550 as
it's unlikely the FIFO is broken. Perhaps a note here to use
'ns16550a' instead unless you have a broken FIFO.

We'll assume these have a type definition elsewhere.

No need to define properties from serial.yaml again. Just 'rts-gpios: true'.
