As requested by Sakari: "The driver changes are still being reviewed. It's been proposed that the max-microamp property be renamed." So, as the DT bindings are not agreed upstream yet, let's revert it. Requested-by:
Sakari Ailus <sakari.ailus@iki.fi> This reverts commit b6100f10.

Changeset 9b174527 added this new macro, ensuring that it is true only if the function is actually reachable. However, newer drivers were added since when it was written. So, change those drivers to also use it. Signed-off-by:

In the media drivers, the v4l2 core knows about all submodules and calls into them from a common function. However this cannot work if the modules that get called are loadable and the core is built-in. In that case we get drivers/built-in.o: In function `set_type': drivers/media/v4l2-core/tuner-core.c:301: undefined reference to `tea5767_attach' drivers/media/v4l2-core/tuner-core.c:307: undefined reference to `tea5761_attach' drivers/media/v4l2-core/tuner-core.c:349: undefined reference to `tda9887_attach' drivers/media/v4l2-core/tuner-core.c:405: undefined reference to `xc4000_attach' This was working previously, until the IS_ENABLED() macro was used to replace the construct like #if defined(CONFIG_DVB_CX24110) || (defined(CONFIG_DVB_CX24110_MODULE) && defined(MODULE)) with the difference that the new code no longer checks whether it is being built as a loadable module itself. To fix this, this new patch adds an 'IS_REACHABLE' macro, which evaluates true in exactly the condition that was used previously. The downside of this is that this trades an obvious link error for a more subtle runtime failure, but it is clear that the change that introduced the link error was unintentional and it seems better to revert it for now. Also, a similar change was originally created by Trent Piepho and then reverted by teh change to the IS_ENABLED macro. Ideally Kconfig would be used to avoid the case of a broken dependency, or the code restructured in a way to turn around the dependency, but either way would require much larger changes here. Fixes: 7b34be71 ("[media] use IS_ENABLED() macro") See-also: c5dec9fb ("V4L/DVB (4751): Fix DBV_FE_CUSTOMISE for card drivers compiled into kernel") Signed-off-by:

This patch addresses a regression introduced in the following patch: commit 5264a522 Author: Shuah Khan <shuahkh@osg.samsung.com> [media] media: tuner xc5000 - release firmwware from xc5000_release() The "priv" struct is actually reference counted, so the xc5000_release() function gets called multiple times for hybrid devices. Because release_firmware() was always being called, it would work fine as expected on the first call but then the second call would corrupt aribtrary memory. Set the pointer to NULL after releasing so that we don't call release_firmware() twice. This problem was detected in the HVR-950q where plugging/unplugging the device multiple times would intermittently show panics in completely unrelated areas of the kernel. Signed-off-by:

Gets a handle to the system clock, already described in the binding document, and calls the appropriate common clock framework functions to mark it prepared/enabled, the common clock framework initially enables the clock and doesn't disable it at least until the device/driver is removed. It's important the systen clock is enabled before register interface is accessed by the driver. The system clock to IR is needed for the driver to communicate with the IR hardware via MMIO accesses on the system bus, so it must not be disabled during use or the driver will malfunction.

Hans Verkuil authored
In the past the V4L2_DV_BT_STD_CEA861 standard bit was used to determine whether the format is a CE (Consumer Electronics) format or not. However, the 640x480p59.94 format is part of the CEA-861 standard, but it is *not* a CE video format. Add a new flag to make this explicit. This information is needed in order to determine the default R'G'B' encoding for the format: for CE video this is limited range (16-235) instead of full range (0-255). The header with all the timings has been updated with this new flag. Signed-off-by:
