be6686b8 - firmware: imx: IMX_SCMI_MISC_DRV should depend on ARCH_MXC

Wed, 05 Feb 2025 14:41:43 +0000

firmware: imx: IMX_SCMI_MISC_DRV should depend on ARCH_MXCThe i.MX System Controller Management Interface firmware is only presenton Freescale i.MX SoCs. Hence add a dependency on ARCH_MXC, to preventasking the user about this driver when configuring a kernel withoutFreescale i.MX platform support.Fixes: 514b2262ade48a05 ("firmware: arm_scmi: Fix i.MX build dependency")Signed-off-by: Geert Uytterhoeven Reviewed-by: Fabio Estevam Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/firmware/imx/Kconfig

514b2262 - firmware: arm_scmi: Fix i.MX build dependency

Fri, 15 Nov 2024 23:05:18 +0000

firmware: arm_scmi: Fix i.MX build dependencyThe newly added SCMI vendor driver references functions in theprotocol driver but needs a Kconfig dependency to ensure it can link,essentially the Kconfig dependency needs to be reversed to match thelink time dependency: | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_write': | fsl_mqs.c:(.text+0x1aa): undefined reference to `scmi_imx_misc_ctrl_set' | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_read': | fsl_mqs.c:(.text+0x1ee): undefined reference to `scmi_imx_misc_ctrl_get'This however only works after changing the dependency in the SND_SOC_FSL_MQSdriver as well, which uses 'select IMX_SCMI_MISC_DRV' to turn on adriver it depends on. This is generally a bad idea, so the best solutionis to change that into a dependency.To allow the ASoC driver to keep building with the SCMI support, thisneeds to be an optional dependency that enforces the link-timedependency if IMX_SCMI_MISC_DRV is a loadable module but notdepend on it if that is disabled.Fixes: 61c9f03e22fc ("firmware: arm_scmi: Add initial support for i.MX MISC protocol")Fixes: 101c9023594a ("ASoC: fsl_mqs: Support accessing registers by scmi interface")Signed-off-by: Arnd Bergmann Acked-by: Mark Brown Acked-by: Shengjiu Wang Message-Id: <20241115230555.2435004-1-arnd@kernel.org>Signed-off-by: Sudeep Holla List of files: /linux-6.15/drivers/firmware/imx/Kconfig

firmware: imx: Add DSP IPC protocol interfaceSome of i.MX8 processors (e.g i.MX8QM, i.MX8QXP) containthe Tensilica HiFi4 DSP for advanced pre- and post-audioprocessing.The communication between Host CPU and DSP firmware istaking place using a shared memory area for message passingand a dedicated Messaging Unit for notifications.DSP IPC protocol offers a doorbell interface usingimx-mailbox API.We use 4 MU channels (2 x TXDB, 2 x RXDB) to implement arequest-reply protocol.Connection 0 (txdb0, rxdb0): - Host writes messasge to shared memory [SHMEM] - Host sends a request [MU] - DSP handles request [SHMEM] - DSP sends reply [MU]Connection 1 (txdb1, rxdb1): - DSP writes a message to shared memory [SHMEM] - DSP sends a request [MU] - Host handles request [SHMEM] - Host sends reply [MU]The protocol interface will be used by a Host client tocommunicate with the DSP. First client will be the i.MX8part from Sound Open Firmware infrastructure.The protocol offers the following interface:On Tx: - imx_dsp_ring_doorbell, will be called to notify the DSP that it needs to handle a request.On Rx: - clients need to provide two callbacks: .handle_reply .handle_request - the callbacks will be used by the protocol on notification arrival from DSP.Signed-off-by: Daniel Baluta Reviewed-by: Oleksij Rempel Signed-off-by: Shawn Guo List of files: /linux-6.15/drivers/firmware/imx/Kconfig
