Thank you! [1/4] arm64: dts: ti: k3-am64-main: Add epwm nodes commit: 13a9a3ef66248a1b6e9acaaa5292d96f8635935b [2/4] arm64: dts: ti: k3-am64-main: Add ecap pwm nodes commit: ae0df139b51a8448afb38e9706f257ab56fea097 [3/4] arm64: dts: ti: k3-am642-evm: Add pwm nodes commit: 8032affdf5a156a467d3b109f32cd9f57ea7afda [4/4] arm64: dts: ti: k3-am642-sk: Add pwm nodes commit: c1fa5ac6c2f475b5140e6323801ed93c24e7e5cf All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.
