media: sun4i-csi: Fix 'Unbalanced pm_runtime_enable!'

2023-02-08T06:30:13+00:00

When removing the module, balance PM runtime enable with the corresponding disable call. Signed-off-by: Oleg Verych Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: sun4i-csi: Use CSI_INT_STA_REG name, fix typo in a comment

2023-02-06T07:41:59+00:00

Fix interrupt status register offset usage to be a defined name CSI_INT_STA_REG (= 0x34) instead of a plain number. Additionally fix a typo in a comment of the same file. Signed-off-by: Oleg Verych Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: sun8i-a83t-mipi-csi2: Clarify return code handling in stream off path

2022-12-12T10:36:00+00:00

Explicitly set ret to zero instead of assigning it and overwriting it later, which is a bit confusing to understand. Signed-off-by: Paul Kocialkowski Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: sun6i-csi: capture: Remove useless ret initialization

2022-12-12T10:36:00+00:00

There is no particular need to assign ret when declaring it as it will be assigned before there is any chance to return it. Signed-off-by: Paul Kocialkowski Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: sun6i-csi: bridge: Error out on invalid port to fix warning

2022-12-12T10:36:00+00:00

The enabled variable is only set for a valid port and used later, which triggers an uninitialized use smatch warning. Explicitly error out in that case to fix the warning.

media: sun6i-csi: clarify return value, fix uninited variable and add missing static

2022-12-06T07:16:39+00:00

This fixes three smatch warnings: drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_bridge.c:629:15: warning: 'enabled' may be used uninitialized [-Wmaybe-uninitialized] drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_bridge.c:439 sun6i_csi_bridge_s_stream() warn: missing error code 'ret' drivers/media/platform/sunxi/sun6i-csi/sun6i_csi_bridge.c:682 sun6i_csi_bridge_notifier_bound() error: uninitialized symbol 'enabled'.

media: sun8i-a83t-mipi-csi2: Register async subdev with no sensor attached

2022-11-25T11:16:02+00:00

This allows the device to probe and register its async subdev without a sensor attached. The rationale is that the parent driver might otherwise wait for the subdev to be registered when it should be available (from the fwnode graph endpoint perspective). This is generally not problematic when the MIPI CSI-2 bridge is the only device attached to the parent, but in the case of a CSI controller that can feed from both MIPI CSI-2 and parallel, it would prevent using the parallel sensor due to the parent waiting for the MIPI CSI-2 subdev to register.

media: sun8i-a83t-mipi-csi2: Require both pads to be connected for streaming

2022-11-25T11:15:04+00:00

The bridge needs both its pads connected to be able to stream data. Enforcing this is useful to produce an error when no sensor is connected.
