-Qualcomm Shared Memory Manager binding
-
-This binding describes the Qualcomm Shared Memory Manager, used to share data
-between various subsystems and OSes in Qualcomm platforms.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be:
- "qcom,smem"
-
-- memory-region:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: handle to memory reservation for main SMEM memory region.
-
-- qcom,rpm-msg-ram:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: handle to RPM message memory resource
-
-- hwlocks:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: reference to a hwspinlock used to protect allocations from
- the shared memory
-
-= EXAMPLE
-The following example shows the SMEM setup for MSM8974, with a main SMEM region
-at 0xfa00000 and the RPM message ram at 0xfc428000:
-
- reserved-memory {
- #address-cells = <1>;
- #size-cells = <1>;
- ranges;
-
- smem_region: smem@fa00000 {
- reg = <0xfa00000 0x200000>;
- no-map;
- };
- };
-
- smem@fa00000 {
- compatible = "qcom,smem";
-
- memory-region = <&smem_region>;
- qcom,rpm-msg-ram = <&rpm_msg_ram>;
-
- hwlocks = <&tcsr_mutex 3>;
- };
-
- soc {
- rpm_msg_ram: memory@fc428000 {
- compatible = "qcom,rpm-msg-ram";
- reg = <0xfc428000 0x4000>;
- };
- };
