* mailbox: Explicitly include correct DT includesRob Herring2023-09-051-0/+1
| | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

* mailbox: arm_mhu: Remove redundant error printing in mhu_probe()Zhen Lei2021-06-261-3/+1
| | | | | | | | | | | | | | When devm_ioremap_resource() fails, a clear enough error message will be printed by its subfunction __devm_ioremap_resource(). The error information contains the device name, failure cause, and possibly resource information. Therefore, remove the error printing here to simplify code and reduce the binary size.

* mailbox: arm_mhu: Match only if compatible is "arm,mhu"Sudeep Holla2020-10-121-0/+3
| | | | | | | | | | | Since we will be soon adding a separate driver based on this ARM MHU driver to support doorbell mode, let us add explicit check to match the default compatible for this driver. This is needed as the probe and match reuses the AMBA device ids currently and don't have any explicit compatible check.

| * mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 msSudeep Holla2015-08-101-1/+1
| | | | | | | | | | | | | | | | | | | | Since the mailbox core users hrtimers now, it can handle much higher resolutions. We can reduce the txpoll_period to 1 ms as the transmit usually takes just few microseconds.
