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

2021-09-01T03:57:45Z

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

2021-08-30T04:50:15Z

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

mailbox: sti: quieten kernel-doc warnings

mailbox: imx: Avoid using val uninitialized in imx_mu_isr()

2021-06-26T17:06:18Z

Clang warns: drivers/mailbox/imx-mailbox.c:284:2: warning: variable 'val' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized] default: ^~~~~~~ drivers/mailbox/imx-mailbox.c:288:7: note: uninitialized use occurs here if (!val) ^~~ drivers/mailbox/imx-mailbox.c:263:9: note: initialize the variable 'val' to silence this warning u32 val, ctrl; ^ = 0 1 warning generated. Prior to commit 91c8c1fbe498 ("mailbox: imx: add xSR/xCR register array"), val was always initialized in imx_mu_isr() but now, it is not initialized in the default case. Return IRQ_NONE like the statement below does and add a message that there is an unhandled type for this switch statement so that it can be updated.
