* [media] v4l: subdev: Move [gs]_std operation to video opsLaurent Pinchart2014-05-241-1/+1
| | | | | | | | | | | | The g_std and s_std operations are video-related, move them to the video ops where they belong.

| | | | | | | | | | | | changeset 2ccf12a did a crappy job when added multi-line comment lines, violating CodingStyle. Change the comments added there to fulfill CodingStyle, and document the platform_data using Documentation/kernel-doc-nano-HOWTO.txt.

* [media] saa7115: Don't use a dynamic arrayMauro Carvalho Chehab2013-05-211-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | At least on s390, gcc complains about that: drivers/media/i2c/saa7115.c: In function 'saa711x_detect_chip.constprop.2': drivers/media/i2c/saa7115.c:1647:1: warning: 'saa711x_detect_chip.constprop.2' uses dynamic stack allocation [enabled by default] While for me the above report seems utterly bogus, as the compiler should be optimizing saa711x_detect_chip, merging it with saa711x_detect_chip and changing: char chip_ver[size - 1]; to char chip_ver[16]; because this function is only called on this code snippet: char name[17]; ... ident = saa711x_detect_chip(client, id, name, sizeof(name)); It seems that gcc is not optimizing it, at least on s390. As getting rid of it is easy, let's do it.

* [media] saa7115: Add register setup and config for gm7113cJon Arne Jørgensen2013-05-211-10/+37
| | | | | | | | | | | | | | | | | | | | | The gm7113c chip is similar to the original saa7113 chip, so I try to re-use most of the saa7113 specific setup-/configuration registers. According to the datasheet, the gm7113c chip has not implemented any register-addresses after 0x1f, so I add a new entry to for the chip to the saa711x_has_reg function. The devices I've seen using this chip will fail to get stable video-sync if these registers are not zeroed: R_14_ANAL_ADC_COMPAT_CNTL R_15_VGATE_START_FID_CHG R_16_VGATE_STOP R_17_MISC_VGATE_CONF_AND_MSB The saa711x_set_v4lstd is updated to send a simpler configuration-table to avoid setting these registers.

| | | | | | | | | | | | | | Adds a code that (auto)detects gm7113c clones. The auto-detection here is not perfect, as, on contrary to what it would be expected by looking into its datasheets some devices would return, instead: saa7115 0-0025: chip 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 @ 0x4a is unknown (found on a device labeled as GM7113C 1145 by Ezequiel Garcia) Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Tested-by: Jon Arne Jørgensen <jonarne@jonarne.no> Tested-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | As we're now seeing other variants from chinese clones, like gm1113c, we'll need to add more bits at the detection code. So, move it into a separate function.
