media: ccs: Fix setting initial sub-device state

2026-03-04T12:21:11Z

[ Upstream commit 31e5191aa11931b53e1242acef4f4375f00ca523 ] Fix setting sub-device state for non-source sub-devices.

media: ccs: Avoid possible division by zero

2026-03-04T12:21:10Z

[ Upstream commit 679f0b7b6a409750a25754c8833e268e5fdde742 ] Calculating maximum M for scaler configuration involves dividing by MIN_X_OUTPUT_SIZE limit register's value. Albeit the value is presumably non-zero, the driver was missing the check it in fact was. Fix this.

2026-02-26T23:01:00Z

[ Upstream commit 3085977e734dab74adebb1dda195befce25addff ] We need to set correct mode for PLL to calculate correct frequency. Signalling mode is known at this point, so use it for that.

media: ccs: Use %pe format specifier

2025-10-17T09:31:15Z

The %pe format specifier is designed to print error pointers. It prints a symbolic error name (eg. -EINVAL) and it makes the code simpler by omitting PTR_ERR() This patch fixes this cocci report: ./i2c/ccs/ccs-core.c:3241:3-10: WARNING: Consider using %pe to print PTR_ERR() ./i2c/ccs/ccs-core.c:3298:3-10: WARNING: Consider using %pe to print PTR_ERR() Signed-off-by: Ricardo Ribalda Acked-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: Remove redundant pm_runtime_mark_last_busy() calls

2025-08-18T07:55:08Z

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

media: ccs: Don't complain about missing "clock-frequency" property

2025-04-25T08:15:34Z

The clock frequency is often available via the clock itself and not read by the driver from the "clock-frequency" property. Don't complain if the property doesn't exist. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: ccs: Don't complain about lack of quirks

2025-04-25T08:15:34Z

Generally any deviance from the standard is handled via CCS static data nowadays and so not having quirks is expected. Don't warn about it. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: ccs: Remove I²C write retry hack

2025-04-25T08:15:33Z

The I²C retry hack has been there in order to address transient I²C register write access issues on a few very old sensors and possibly it has addressed also first I²C access problems (device not responding until a certain amount of time has passed) but that is now separately handled. The retry hack has a good potential for introducing hard to debug problems in updating sensor settings while streaming. Remove it and instead pass those rare errors to the user space -- which is also what virtually all other drivers do. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: ccs: Use read_poll_timeout() in reset polling

2025-04-25T08:15:33Z

Use read_poll_timeout() in polling the device after a reset, either hard or soft. While at it, improve the related error message. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: ccs: Try a little longer to access the sensor before giving up

2025-04-25T08:15:33Z

Some sensors take longer to respond after reset than the spec-required time. Try up to 1 s for the sensor to become accessible. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil
