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
