2019-08-13media: i2c: Convert to new i2c device probe()Kieran Bingham1-3/+2
The I2C core framework provides a simplified probe framework from commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"). These drivers do not utilise the i2c_device_id table in the probe, so we can easily convert them to utilise the simplified i2c driver registration.

2018-11-23media: adv*/tc358743/ths8200: fill in min width/height/pixelclockHans Verkuil1-1/+1
The v4l2_dv_timings_cap struct is used to do sanity checks when setting and enumerating DV timings, ensuring that only valid timings as per the HW capabilities are allowed. However, many drivers just filled in 0 for the minimum width, height or pixelclock frequency. This can cause timings with e.g. 0 as width and height to be accepted, which will in turn lead to a potential division by zero. Fill in proper values are minimum boundaries. 640x350 was chosen since it is the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the v4l2-dv-timings.h header).

i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by <linux/i2c.h> work with const i2c_device_id. So mark the non-const structs as const.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "This series include: - a new Remote Controller driver for ST SoC with the corresponding DT bindings - a new frontend (cx24117) - a new I2C camera flash driver (lm3560) - a new mem2mem driver for TI SoC (ti-vpe) - support for Raphael r828d added to r820t driver - some improvements on buffer allocation at VB2 core - usual driver fixes and improvements PS this time, we have a smaller number of patches. While it is hard to pinpoint to the reasons, I believe that it is mainly due to: 1) there are several patch series ready, but depending on DT review. I decided to grant some extra time for DT maintainers to look on it, as they're expecting to have more time with the changes agreed during ARM mini-summit and KS. If they can't review in time for 3.14, I'll review myself and apply for the next merge window. 2) I suspect that having both LinuxCon EU and LinuxCon NA happening during the same merge window affected the development productivity, as several core media developers participated on both events" * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (151 commits) [media] media: st-rc: Add ST remote control driver [media] gpio-ir-recv: Include linux/of.h header [media] tvp7002: Include linux/of.h header [media] tvp514x: Include linux/of.h header [media] ths8200: Include linux/of.h header [media] adv7343: Include linux/of.h header [media] v4l: Fix typo in v4l2_subdev_get_try_crop() [media] media: i2c: add driver for dual LED Flash, lm3560 [media] rtl28xxu: add 15f4:0131 Astrometa DVB-T2 [media] rtl28xxu: add RTL2832P + R828D support [media] rtl2832: add new tuner R828D [media] r820t: add support for R828D [media] media/i2c: ths8200: fix build failure with gcc 4.5.4 [media] Add support for KWorld UB435-Q V2 [media] staging/media: fix msi3101 build errors [media] ddbridge: Remove casting the return value which is a void pointer [media] ngene: Remove casting the return value which is a void pointer [media] dm1105: remove unneeded not-null test [media] sh_mobile_ceu_camera: remove deprecated IRQF_DISABLED [media] media: rcar_vin: Add preliminary r8a7790 support ...

v4l2-common.c contained a bunch of dv-timings related functions. Move that to the new v4l2-dv-timings.c which is a more appropriate place for them.
