Merge tag 'qcom-soc-for-4.4' of git://codeaurora.org/quic/kernel/agross-msm into next/drivers
Pull "Qualcomm ARM Based SoC Updates for 4.4" from Andy Gross: * Implement id_table driver matching in SMD * Avoid NULL pointer exception on remove of SMEM * Reorder SMEM/SMD configs * Make qcom_smem_get() return a pointer * Handle big endian CPUs correctly in SMEM * Represent SMD channel layout in structures * Use __iowrite32_copy() in SMD * Remove use of VLAIs in SMD * Handle big endian CPUs correctly in SMD/RPM * Handle big endian CPUs corretly in SMD * Reject sending SMD packets that are too large * Fix endianness issue in SCM __qcom_scm_is_call_available * Add missing prototype for qcom_scm_is_available() * Correct SMEM items for upper channels * Use architecture level to build SCM correctly * Delete unneeded of_node_put in SMD * Correct active/slep state flagging in SMD/RPM * Move RPM message ram out of SMEM DT node * tag 'qcom-soc-for-4.4' of git://codeaurora.org/quic/kernel/agross-msm: soc: qcom: smem: Move RPM message ram out of smem DT node soc: qcom: smd-rpm: Correct the active vs sleep state flagging soc: qcom: smd: delete unneeded of_node_put firmware: qcom-scm: build for correct architecture level soc: qcom: smd: Correct SMEM items for upper channels qcom-scm: add missing prototype for qcom_scm_is_available() qcom-scm: fix endianess issue in __qcom_scm_is_call_available soc: qcom: smd: Reject send of too big packets soc: qcom: smd: Handle big endian CPUs soc: qcom: smd_rpm: Handle big endian CPUs soc: qcom: smd: Remove use of VLAIS soc: qcom: smd: Use __iowrite32_copy() instead of open-coding it soc: qcom: smd: Represent channel layout in structures soc: qcom: smem: Handle big endian CPUs soc: qcom: Make qcom_smem_get() return a pointer soc: qcom: Reorder SMEM/SMD configs soc: qcom: smem: Avoid NULL pointer exception on remove soc: qcom: smd: Implement id_table driver matching
