2018-01-04media: fix usage of whitespaces and on indentationMauro Carvalho Chehab1-3/+3
On several places, whitespaces are being used for indentation, or even at the end of the line. Fix them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-10-31media: davinci: make ccdc_hw_device structures constBhumika Goyal1-1/+1
Make these structures const as they are only getting passed to the functions vpfe_{register/unregister}_ccdc_device having the argument as const. Structures found using Coccinelle and changes done by hand.

2017-07-20media: platform: davinci: drop VPFE_CMD_S_CCDC_RAW_PARAMSPrabhakar Lad1-148/+3
drop VPFE_CMD_S_CCDC_RAW_PARAMS ioctl from dm355/dm644x following reasons: - This ioctl was never in public api and was only defined in kernel header. - The function set_params constantly mixes up pointers and phys_addr_t numbers. - This is part of a 'VPFE_CMD_S_CCDC_RAW_PARAMS' ioctl command that is described as an 'experimental ioctl that will change in future kernels'. - The code to allocate the table never gets called after we copy_from_user the user input over the kernel settings, and then compare them for inequality. - We then go on to use an address provided by user space as both the __user pointer for input and pass it through phys_to_virt to come up with a kernel pointer to copy the data to. This looks like a trivially exploitable root hole.

2017-01-27[media] media: Drop FSF's postal address from the source code filesSakari Ailus1-4/+0
Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated. The patch has been created with the following command without manual edits: git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \ drivers/media/ include/media|while read i; do i=$i perl -e ' open(F,"< $ENV{i}"); $a=join("", <F>); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m && $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m; close(F); open(F, "> $ENV{i}"); print F $a; close(F);'; done Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>
2016-10-21[media] davinci: don't break long linesMauro Carvalho Chehab1-2/+2
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Acked-by: Lad, Prabhakar <prabhakar.csengg@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-01-25[media] davinci: ccdc_update_raw_params() frees the wrong thingAl Viro1-1/+1
Passing a physical address to free_pages() is a bad idea. config_params->fault_pxl.fpc_table_addr is set to virt_to_phys() of __get_free_pages() return value; what we should pass to free_pages() is its phys_to_virt(). ccdc_close() does that properly, but ccdc_update_raw_params() doesn't.

2014-08-26[media] dm644x_ccdc: use unsigned long for fpc_table_addrMauro Carvalho Chehab1-2/+2
The fpc_table_addr is used as an unsigned integer that stores an address. At the Kernel, the proper type for such integers is unsigned long. This generates lots of warnings when compiling on 64 bits. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-04-14[media] media: davinci: vpss: enable vpss clocksLad, Prabhakar1-44/+0
By default the VPSS clocks were enabled in capture driver for davinci family which creates duplicates for dm355/dm365/dm644x. This patch adds support to enable the VPSS clocks in VPSS driver, which avoids duplication of code and also adding clock aliases. This patch uses PM runtime API to enable/disable clock, instead of DaVinci clock framework. con_ids for master and slave clocks of vpss is added in pm_domain. This patch cleanups the VPSS clock enabling in the capture driver, and also removes the clock alias in machine file. Along side adds a vpss slave clock for DM365 as mentioned by Sekhar (https://patchwork.kernel.org/patch/1221261/). The Suspend/Resume in dm644x_ccdc.c which enabled/disabled the VPSS clock is now implemented as part of the VPSS driver.

2013-03-19[media] davinci/dm644x_ccdc: fix compiler warningHans Verkuil1-5/+8
drivers/media/platform/davinci/dm644x_ccdc.c: In function ‘validate_ccdc_param’: drivers/media/platform/davinci/dm644x_ccdc.c:233:32: warning: comparison between ‘enum ccdc_gama_width’ and ‘enum ccdc_data_size’ [-Wenum-compare] It took a bit of work, see this thread of an earlier attempt to fix this: https://patchwork.kernel.org/patch/1923091/ I've chosen not to follow the suggestions in that thread since gamma_width is really a different property from data_size. What you really want is to know if gamma_width fits inside data_size and for that you need to translate each enum into a maximum bit number so you can safely compare the two. So I put in two static inline translation functions instead, keeping the rest of the code the same (except for fixing the 'gama' typo).

2013-01-03Drivers: media: remove __dev* attributes.Greg Kroah-Hartman1-2/+2
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
