2024-12-09media: i2c: tc358743: Fix crash in the probe error path when using pollingAlexander Shiyan
commit 869f38ae07f7df829da4951c3d1f7a2be09c2e9a upstream. If an error occurs in the probe() function, we should remove the polling timer that was alarmed earlier, otherwise the timer is called with arguments that are already freed, which results in a crash. ------------[ cut here ]------------ WARNING: CPU: 3 PID: 0 at kernel/time/timer.c:1830 __run_timers+0x244/0x268 Modules linked in: CPU: 3 UID: 0 PID: 0 Comm: swapper/3 Not tainted 6.11.0 #226 Hardware name: Diasom DS-RK3568-SOM-EVB (DT) pstate: 804000c9 (Nzcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : __run_timers+0x244/0x268 lr : __run_timers+0x1d4/0x268 sp : ffffff80eff2baf0 x29: ffffff80eff2bb50 x28: 7fffffffffffffff x27: ffffff80eff2bb00 x26: ffffffc080f669c0 x25: ffffff80efef6bf0 x24: ffffff80eff2bb00 x23: 0000000000000000 x22: dead000000000122 x21: 0000000000000000 x20: ffffff80efef6b80 x19: ffffff80041c8bf8 x18: ffffffffffffffff x17: ffffffc06f146000 x16: ffffff80eff27dc0 x15: 000000000000003e x14: 0000000000000000 x13: 00000000000054da x12: 0000000000000000 x11: 00000000000639c0 x10: 000000000000000c x9 : 0000000000000009 x8 : ffffff80eff2cb40 x7 : ffffff80eff2cb40 x6 : ffffff8002bee480 x5 : ffffffc080cb2220 x4 : ffffffc080cb2150 x3 : 00000000000f4240 x2 : 0000000000000102 x1 : ffffff80eff2bb00 x0 : ffffff80041c8bf0 Call trace:  __run_timers+0x244/0x268  timer_expire_remote+0x50/0x68  tmigr_handle_remote+0x388/0x39c  run_timer_softirq+0x38/0x44  handle_softirqs+0x138/0x298  __do_softirq+0x14/0x20  ____do_softirq+0x10/0x1c  call_on_irq_stack+0x24/0x4c  do_softirq_own_stack+0x1c/0x2c  irq_exit_rcu+0x9c/0xcc  el1_interrupt+0x48/0xc0  el1h_64_irq_handler+0x18/0x24  el1h_64_irq+0x7c/0x80  default_idle_call+0x34/0x68  do_idle+0x23c/0x294  cpu_startup_entry+0x38/0x3c  secondary_start_kernel+0x128/0x160  __secondary_switched+0xb8/0xbc ---[ end trace 0000000000000000 ]--- Fixes: 4e66a52a2e4c ("[media] tc358743: Add support for platforms without IRQ line") Signed-off-by: Alexander Shiyan <eagle.alexander923@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 9f070b1862f3411b8bcdfd51a8eaad25286f9deb upstream. The v4l2_detect_cvt/gtf functions should check the result against the timing capabilities: these functions calculate the timings, so if they are out of bounds, they should be rejected. To do this, add the struct v4l2_dv_timings_cap as argument to those functions. This required updates to the adv7604 and adv7842 drivers since the prototype of these functions has now changed. The timings struct that is passed to v4l2_detect_cvt/gtf in those two drivers is filled with the timings detected by the hardware. The vivid driver was also updated, but an additional check was added: the width and height specified by VIDIOC_S_DV_TIMINGS has to match the calculated result, otherwise something went wrong. Note that vivid *emulates* hardware, so all the values passed to the v4l2_detect_cvt/gtf functions came from the timings struct that was filled by userspace and passed on to the driver via VIDIOC_S_DV_TIMINGS. So these fields can contain random data. Both the constraints check via struct v4l2_dv_timings_cap and the additional width/height check ensure that the resulting timings are sane and not messed up by the v4l2_detect_cvt/gtf calculations.

2024-08-31media: imx335: Fix reset-gpio handlingUmang Jain
Rectify the logical value of reset-gpio so that it is set to 0 (disabled) during power-on and to 1 (enabled) during power-off. Set the reset-gpio to GPIO_OUT_HIGH at initialization time to make sure it starts off in reset. Also drop the "Set XCLR" comment which is not-so-informative. The existing usage of imx335 had reset-gpios polarity inverted (GPIO_ACTIVE_HIGH) in their device-tree sources. With this patch included, those DTS will not be able to stream imx335 anymore. The reset-gpio polarity will need to be rectified in the device-tree sources as shown in [1] example, in order to get imx335 functional again (as it remains in reset prior to this fix).

2024-08-31media: ov5675: Fix power on/off delay timingsBryan O'Donoghue
The ov5675 specification says that the gap between XSHUTDN deassert and the first I2C transaction should be a minimum of 8192 XVCLK cycles. Right now we use a usleep_rage() that gives a sleep time of between about 430 and 860 microseconds. On the Lenovo X13s we have observed that in about 1/20 cases the current timing is too tight and we start transacting before the ov5675's reset cycle completes, leading to I2C bus transaction failures. The reset racing is sometimes triggered at initial chip probe but, more usually on a subsequent power-off/power-on cycle e.g. [ 71.451662] ov5675 24-0010: failed to write reg 0x0103. error = -5 [ 71.451686] ov5675 24-0010: failed to set plls The current quiescence period we have is too tight. Instead of expressing the post reset delay in terms of the current XVCLK this patch converts the power-on and power-off delays to the maximum theoretical delay @ 6 MHz with an additional buffer. 1.365 milliseconds on the power-on path is 1.5 milliseconds with grace. 85.3 microseconds on the power-off path is 90 microseconds with grace.

2024-08-25media: mt9p031: Extend match support for OF tablesBiju Das
The driver has an OF match table, still, it uses an ID lookup table for retrieving match data. Currently, the driver is working on the assumption that an I2C device registered via OF will always match a legacy I2C device ID. The correct approach is to have an OF device ID table using i2c_get_match_data() if the devices are registered via OF/ID. Unify the OF/ID table by using MEDIA_BUS_FMT as match data for both these tables and replace the ID lookup table for the match data by i2c_get_match_data() and simplifly probe() and mt9p031_init_state(). While at it, remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing.
