dt-bindings: serial: renesas,scif: Fix 4th IRQ for 4-IRQ SCIFs

2023-03-29T08:58:44+00:00

The fourth interrupt on SCIF variants with four interrupts (RZ/A1) is
the Break interrupt, not the Transmit End interrupt (like on SCI(g)).
Update the description and interrupt name to fix this.

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add node lifecycle unit tests

   - Add of_property_present() helper aligned with fwnode API

   - Print more information on reserved regions on boot

   - Update dtc to upstream v1.6.1-66-gabbd523bae6e

   - Use strscpy() to instead of strncpy() in DT core

   - Add option for schema validation on %.dtb targets

  Bindings:

   - Add/fix support for listing multiple patterns in DT_SCHEMA_FILES

   - Rework external memory controller/bus bindings to properly support
     controller specific child node properties

   - Convert loongson,ls1x-intc, fcs,fusb302, sil,sii8620, Rockchip
     RK3399 PCIe, Synquacer I2C, and Synquacer EXIU bindings to DT
     schema format

   - Add RiscV SBI PMU event mapping binding

   - Add missing contraints on Arm SCMI child node allowed properties

   - Add a bunch of missing Socionext UniPhier glue block bindings and
     example fixes

   - Various fixes for duplicate or conflicting type definitions on DT
     properties"

dt-bindings: serial: snps-dw-apb-uart: add dma & dma-names properties

2023-02-09T12:27:40+00:00

Commit 0c559bc8abfb ("dt-bindings: serial: restrict possible child node
names") exposed the Allwinner D1 devicetrees as users of unevaluated
properties, with a slew of similar warnings now appearing during
dtbs_check:
sun20i-d1-nezha.dtb: serial@2500400: Unevaluated properties are not allowed ('dma-names', 'dmas' were unexpected)

Document the missing properties.

dt-bindings: serial: restrict possible child node names

2023-02-07T21:47:27+00:00

The re-usable serial.yaml schema matches every property with ".*"
pattern, thus any other schema referencing it will not report unknown
(unevaluated) properties.  This hides several wrong properties.  It is
a limitation of dtschema, thus provide a simple workaround: expect
children to be only of few names matching upstream usage (Bluetooth,
GNSS, GPS and MCU).

dt-bindings: reference MC peripheral properties in relevant devices

2023-02-07T21:47:27+00:00

Several devices can be attached to memory controllers (or memory-mapped
buses), thus they can come with additional controller-specific
properties, e.g. devices wired under Intel IXP4XX bus: cfi-flash,
intel,ixp4xx-compact-flash, NS8250 serial and MAX6369 watchdog.

Referencing Memory Controller or IXP4XX bus peripheral properties fixes
few dtbs_check warnings like:

  intel-ixp42x-gateworks-gw2348.dtb: ide@1,0: Unevaluated properties are not allowed
    ('intel,ixp4xx-eb-ahb-split-transfers', 'intel,ixp4xx-eb-byte-access', ... ' were unexpected)

dt-bindings: serial: st,stm32-uart: drop common properties

2023-02-01T05:13:36+00:00

The binding references serial and rs485 schemas, so there is no need to
list their properties.  Simplify a bit by removing unneeded entries.
