4670c8c3 - media: ipu-bridge: Fix Kconfig dependencies

Wed, 27 Sep 2023 08:53:12 +0000

media: ipu-bridge: Fix Kconfig dependenciesThe current Kconfig symbol dependencies allow having the following Kconfigsymbol values CONFIG_IPU_BRIDGE=m CONFIG_VIDEO_IPU3_CIO2=y CONFIG_CIO2_BRIDGE=nThis does not work as the IPU bridge API is conditional toIS_ENABLED(CONFIG_IPU_BRIDGE). Fix this by changing the dependencies sothat CONFIG_IPU_BRIDGE can be separately selected.The CONFIG_CIO2_BRIDGE symbol becomes redundant as a result and isremoved.Fixes: 2545a2c02ba1 ("media: ipu3-cio2: allow ipu_bridge to be a module again")Suggested-by: Arnd Bergmann Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil List of files: /linux-6.15/drivers/media/pci/intel/Kconfig

29006e19 - media: pci: intel: ivsc: Add CSI submodule

Sat, 08 Jul 2023 14:52:14 +0000

media: pci: intel: ivsc: Add CSI submoduleCSI is a submodule of IVSC which can route camera sensor datato the outbound MIPI CSI-2 interface.The interface communicating with firmware is via MEI. There isa separate MEI UUID, which this driver uses to enumerate.To route camera sensor data to host, the information of linkfrequency and number of data lanes is sent to firmware bysending MEI command when starting stream.CSI also provides a privacy mode. When privacy mode is turnedon, camera sensor can't be used. This means that both IVSC andhost Image Processing Unit(IPU) can't get image data. And whenthis mode is turned on, user is notified via v4l2 controlcallback.Link: https://lore.kernel.org/linux-media/20230803115550.1601965-2-sakari.ailus@linux.intel.comSigned-off-by: Wentong Wu Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/pci/intel/Kconfig

2545a2c0 - media: ipu3-cio2: allow ipu_bridge to be a module again

Thu, 27 Jul 2023 12:22:58 +0000

media: ipu3-cio2: allow ipu_bridge to be a module againThis code was previously part of the VIDEO_IPU3_CIO2 driver, which couldbe built-in or a loadable module, but after the move it turned into abuiltin-only driver. This fails to link when the I2C subsystem is amodule:x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_unregister_sensors':ipu-bridge.c:(.text+0x50): undefined reference to `i2c_unregister_device'x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_init':ipu-bridge.c:(.text+0x9c9): undefined reference to `i2c_acpi_new_device_by_fwnode'In general, drivers should not have to be built-in, so change the optionto a tristate with the corresponding dependency. This in turn opens anew problem with the dependency, as the IPU bridge can be a loadable modulewhile the ipu3 driver itself is built-in, producing a new link failure:86_64-linux-ld: drivers/media/pci/intel/ipu3/ipu3-cio2.o: in function `cio2_pci_probe':ipu3-cio2.c:(.text+0x197e): undefined reference to `ipu_bridge_init'In order to fix this, restore the old Kconfig option that controlledthe ipu bridge driver before it was split out, but make it select ahidden symbol that now corresponds to the bridge driver.When other drivers get added that share ipu-bridge, this should coverall corner cases, and allow any combination of them to be built-inor modular.Link: https://lore.kernel.org/linux-media/20230727122331.2421453-1-arnd@kernel.orgFixes: 881ca25978c6 ("media: ipu3-cio2: rename cio2 bridge to ipu bridge and move out of ipu3")'Signed-off-by: Arnd Bergmann Reviewed-by: Andy Shevchenko Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/pci/intel/Kconfig

881ca259 - media: ipu3-cio2: rename cio2 bridge to ipu bridge and move out of ipu3

Thu, 18 May 2023 10:05:21 +0000

media: ipu3-cio2: rename cio2 bridge to ipu bridge and move out of ipu3cio2 bridge was involved along with IPU3. However, in fact all Intel IPUsbesides IPU3 CIO2 need this bridge driver. This patch move bridge driverout of ipu3 directory and rename as ipu-bridge. Then it can be worked withIPU3 and other Intel IPUs.Signed-off-by: Bingbu Cao Reviewed-by: Daniel Scally Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/pci/intel/Kconfig
