2023-05-04mailbox: qcom-apcs-ipc: do not grow the of_device_idKrzysztof Kozlowski1-5/+6
Re-organize the compatible devices and add a comment to avoid unneeded of_device_id growth with every new SoC. These devices have quite a lot of similarities and they can use only one compatible fallback for driver binding.

2023-02-23mailbox: qcom-apcs-ipc: add IPQ5332 APSS clock supportKathiravan T1-0/+1
IPQ5332 has the APSS clock controller utilizing the same register space as the APCS, so provide access to the APSS utilizing a child device like other IPQ chipsets. Like IPQ6018, the same controller and driver is used, so utilize IPQ6018 match data for IPQ5332.

2021-06-26mailbox: qcom: Use PLATFORM_DEVID_AUTO to register platform deviceShawn Guo1-1/+1
In adding APCS clock support for MSM8939, the second clock registration fails due to duplicate device name like below. [ 0.519657] sysfs: cannot create duplicate filename '/bus/platform/devices/qcom-apcs-msm8916-clk' ... [ 0.661158] qcom_apcs_ipc b111000.mailbox: failed to register APCS clk This is because MSM8939 has 3 APCS instances for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache Coherent Interconnect). Although only APCS of Cluster0 and Cluster1 have IPC bits, each of 3 APCS has A53PLL clock control bits. That said, 3 'qcom-apcs-msm8916-clk' devices need to be registered to instantiate all 3 clocks. Use PLATFORM_DEVID_AUTO rather than PLATFORM_DEVID_NONE for platform_device_register_data() call to fix the issue above.

2020-06-10mailbox: qcom: Add clock driver name in apcs mailbox driver dataSivaprakash Murugesan1-18/+38
Some apcs mailbox devices supports a clock driver, the compatible strings of devices supporting clock driver along with the clock driver name are maintained in a separate structure within the mailbox driver. And the clock driver is added based on device match. With increase in number of devices supporting the clock feature move the clock driver name inside the driver data. so that we can use a single API to get the register offset of mailbox driver and clock driver name together, and the clock driver will be added based on the driver data.
