PATCH 1/1 ARM: dts: OMAP: Add hwlock-base-id property to hwspinlock nodes

Add the generic property "hwlock-base-id" to the hwspinlock DT nodes on all applicable OMAP SoCS (OMAP4, OMAP5, DRA7, AM33xx and AM43xx). This common property is required by the hwspinlock core to be able to translate client locks properly. All the current OMAP SoCs only have a single instance of the IP, and so will use a common value of 0.

PATCH 1/1 ARM: dts: OMAP: Add hwlock-base-id property to hwspinlock nodes

Quoted 5 lines · Suman Anna

Add the generic property "hwlock-base-id" to the hwspinlock DT nodes on all applicable OMAP SoCS (OMAP4, OMAP5, DRA7, AM33xx and AM43xx). This common property is required by the hwspinlock core to be able to translate client locks properly. All the current OMAP SoCs only have a single instance of the IP, and so will use a common value of 0.

As it seems the base-id binding is still under a discussion, I'll untag this one. Suman, please resend once the related spinlock changes are queued.

Thanks,

Tony
