a=ed25519; pk=IqNDwUZKECEA+n8wXctFLBbYL9NhFstZNbOznm/nX1k= This series converts the Texas Instruments OMAP Real Time Clock (RTC) binding from the legacy format to dt-schema. The am3352-rtc is compatible with the da830-trc. Update the compatible string to include the ti,da830-rtc fallback Two legacy, undocumented properties were discovered in the upstream device trees: - 'ext-clk-src' in am57xx-idk-common.dtsi - 'ti,no-init' in am335x-shc.dts Both properties are completely unhandled by the rtc-omap driver. Patches 1 and 2 remove them from the device trees. Patch 3 then introduces the new YAML schema. Signed-off-by: Bhargav Joshi --- Changes in v3: - fixed dts where only am3352-rtc was used without da830-rtc - fixed compatible where am3352 is only compatible with da830 - simplified clock-output-names property and pins property - Link to v2: https://lore.kernel.org/r/20260725-ti-omap-rtc-v2-0-13f765ca96b3@gmail.com Changes in v2: - Patch 1: unchanged - Patch 2: unchanged - Patch 3: Removed left out legacy text binding and Added constraint block restricting 'system-power-controller' and 'ext-wakeup' subnodes strictly to hardware variants that support PMIC mode - Link to v1: https://lore.kernel.org/r/20260724-ti-omap-rtc-v1-0-ffef78853cd6@gmail.com --- Bhargav Joshi (4): ARM: dts: ti: am57xx-idk-common: Remove unused ext-clk-src property ARM: dts: ti: am335x-shc: Remove unused ti,no-init property ARM: dts: omap: dra7: add da830 fallback to am3352 rtc compatible string dt-bindings: rtc: ti,omap-rtc: Convert to DT schema Documentation/devicetree/bindings/rtc/rtc-omap.txt | 53 -------- .../devicetree/bindings/rtc/ti,omap-rtc.yaml | 140 +++++++++++++++++++++ arch/arm/boot/dts/ti/omap/am335x-shc.dts | 4 - arch/arm/boot/dts/ti/omap/am57xx-idk-common.dtsi | 1 - arch/arm/boot/dts/ti/omap/dra7-l4.dtsi | 2 +- 5 files changed, 141 insertions(+), 59 deletions(-) --- base-commit: 48a5a7ab8d6ab7090564339e039c421f315de912 change-id: 20260724-ti-omap-rtc-6a5c5888e7e3 Best regards, -- Bhargav
