mailbox: mtk-cmdq: Fix local clock ID usage

2021-11-18T18:16:35+00:00

[ Upstream commit 0a5ad4322927ee4aaba6facc0e4faf1ab6c0d48e ] 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.

mailbox: mtk-cmdq: Validate alias_id on probe

[ Upstream commit 5c154b6a51c2d2d7f266b3ef49b7dd1dc8cb5b65 ] of_alias_get_id() may return -ENODEV which leads to illegal access to the cmdq->clocks array. Adding a check over alias_id to prevent the unexpected behavior.

mailbox: Remove WARN_ON for async_cb.cb in cmdq_exec_done

2021-11-18T18:16:34+00:00

[ Upstream commit ce1537fe288469bf68ee0aabdb860a790b4755ef ] Because mtk_drm_crtc_update_config is not using cmdq_pkt_flush_async, it won't have pkt->async_cb.cb anymore. So remove the WARN_ON check of pkt->async_cb.cb at cmdq_exec_done.

mailbox: cmdq: add multi-gce clocks support for mt8195

2021-09-01T03:57:45+00:00

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.

mailbox: qcom-ipcc: Enable loading QCOM_IPCC as a module

2021-08-30T04:50:15+00:00

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. Signed-off-by: Amit Pundir Reviewed-by: Manivannan Sadhasivam Signed-off-by: Jassi Brar
