2021-10-29mailbox: apple: Add driver for Apple mailboxesSven Peter3-0/+398
Apple SoCs such as the M1 come with various co-processors. Mailboxes are used to communicate with those. This driver adds support for two variants of those mailboxes. Signed-off-by: Sven Peter <[email protected]> Signed-off-by: Jassi Brar <[email protected]>
2021-10-19mailbox: mtk-cmdq: Fix local clock ID usageFei Shao1-5/+3
In the probe function, the clock IDs were pointed to local variables which should only be used in the same code block, and any access to them after the probing stage becomes an use-after-free case. Since there are only limited variants of the gce clock names so far, we can just declare them as static constants to fix the issue.

2021-08-31mailbox: cmdq: add multi-gce clocks support for mt8195jason-jh.lin1-22/+79
For the design of GCE hardware event signal transportation, evnet rx will send the event signal to all GCE event merges after receiving the event signal from the other hardware. Because GCE event merges need to response to event rx, their clocks must be enabled at that time. To make sure all the gce clock is enabled while receiving the hardware event, each cmdq mailbox should enable or disable the others gce clk at the same time.

This patch enables the qcom_ipcc driver to be loaded as a module. IPCC is fairly core to system, so as such it should never be unloaded. It registers as a mailbox + irq controller and the irq controller drivers in kernel are not supposed to be unloaded as they don't have the visibility over the clients consuming the irqs. Hence adding supress_bind_attrs to disable bind/unbind via sysfs.

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.

Some sensors connected to Unisoc mailbox will send data very frequently. This makes channel 0 very busy and the messages from other remote cores not able to be handled as soon as possible. It's a trick (un-documented) from Unisoc ASIC designers to resolve this special requirement that an inbox assigned to one of the remote cores before was modified to be exposed to host cpu core. Then from host side, a supplementary inbox is added for transferring mass but not emergency messages from the remote cores, such as step counting sensor, with an independent FIFO and interrupt which is as same as channel 0. Meanwihle, inbox part of this channel is still kept for original remote core to use.
