2022-02-23media: cec: seco: Drop pointless includeLinus Walleij1-2/+1
This driver uses GPIO descriptors not the old legacy GPIO API so stop including <linux/gpio.h>. Fix a bug using a completely unrelated legacy API flag GPIOF_IN by switching to the actually desired flag GPIOD_IN.

2021-05-10media: s5p: fix pm_runtime_get_sync() usage countMauro Carvalho Chehab1-1/+4
The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. Replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter, avoiding a potential PM usage counter leak. While here, check if the PM runtime error was caught at s5p_cec_adap_enable().

There's a bug at s5p_cec_adap_enable(): if called to disable the device, it should call pm_runtime_put() instead of pm_runtime_disable(), as the goal here is to decrement the usage_count and not to disable PM runtime.

2020-09-03media: rc: harmonize infrared durations to microsecondsSean Young1-1/+1
rc-core kapi uses nanoseconds for infrared durations for receiving, and microseconds for sending. The uapi already uses microseconds for both, so this patch does not change the uapi. Infrared durations do not need nanosecond resolution. IR protocols do not have durations shorter than about 100 microseconds. Some IR hardware offers 250 microseconds resolution, which is sufficient for most protocols. Better hardware has 50 microsecond resolution and is enough for every protocol I am aware off. Unify on microseconds everywhere. This simplifies the code since less conversion between microseconds and nanoseconds needs to be done.

2020-07-04media: cros-ec-cec: do not bail on device_init_wakeup failureDariusz Marcinkiewicz1-5/+1
Do not fail probing when device_init_wakeup fails. device_init_wakeup fails when the device is already enabled as wakeup device. Hence, the driver fails to probe the device if: - The device has already been enabled for wakeup (by e.g. sysfs) - The driver has been unloaded and is being loaded again. This goal of the patch is to fix the above cases. Overwhelming majority of the drivers do not check device_init_wakeup return code.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada1-1/+1
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <[email protected]>
2020-04-29media: cec-gpio: handle gpiod_get_value errors correctlyHans Verkuil1-7/+11
gpiod_get_value() can return negative values if an error occurs. In several places this error code was ignored. Ensure that errors codes are handled correctly throughout the CEC pin framework and CEC pin drivers. The return code of the cec_pin_ops read() callback had to be changed from 'bool' to 'int', which mean the prototype of that callback in the sun4i drm driver also had to be changed.

While select would be a great idea for most archs, this causes a breakage with s390: "I don't think that's a good idea, as it suddenly enables selecting all PCI drivers on platforms that do not have PCI.

2020-04-15media: cec: rename CEC platform drivers config optionsMauro Carvalho Chehab10-28/+28
Most CEC platform drivers are using VIDEO_*_CEC pattern, some with an _HDMI extension too. Well, they're not related to V4L2 support, and we don't really need those big config names. So drop VIDEO_* from them, remove _HDMI (if present) and move CEC to the start. This way, all platform driver options are now CEC_<driver>.
