Hi Nishanth, The following series adds the HwSpinlock and Mailbox DT nodes for AM64x SoCs on AM64x-EVM and AM64x-SK boards. The bindings for both drivers were merged in 5.12-rc1. Patches are based on top of your latest ti-k3-dts-next branch, commit 04a80a75baa1 ("arm64: dts: ti: k3-am642-evm: Add USB support"). Following is the patch summary: - Patch 1 adds the HwSpinlock node - Patch 2 adds all the relevant Mailbox clusters that generate interrupts towards A53 - Patches 3 and 4 add the actual communication sub-mailbox devices and disables unused clusters for AM64x EVM and AM64x SK boards respectively.
