mailbox: tegra: Fix superfluous IRQ error message

2019-12-13T07:42:19Z

commit c745da8d4320c49e54662c0a8f7cb6b8204f44c4 upstream. Commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()") added an error message to avoid drivers having to print an error message when IRQ lookup fails. However, there are some cases where IRQs are optional and so new optional versions of the platform_get_irq*() APIs have been added for these cases. The IRQs for Tegra HSP module are optional because not all instances of the module have the doorbell and all of the shared interrupts. Hence, since the above commit was applied the following error messages are now seen on Tegra194 ... ERR KERN tegra-hsp c150000.hsp: IRQ doorbell not found ERR KERN tegra-hsp c150000.hsp: IRQ shared0 not found The Tegra HSP driver deliberately does not fail if these are not found and so fix the above errors by updating the Tegra HSP driver to use the platform_get_irq_byname_optional() API.

mailbox: mediatek: cmdq: clear the event in cmdq initial flow

2019-09-17T05:40:05Z

GCE hardware stored event information in own internal sysram, if the initial value in those sysram is not zero value it will cause a situation that gce can wait the event immediately after client ask gce to wait event but not really trigger the corresponding hardware. In order to make sure that the wait event function is exactly correct, we need to clear the sysram value in cmdq initial flow.
