2016-12-14drm/exynos: support exynos5422 mipi-dsiAndrzej Hajda
This patch supports mipi dsi for exynos5422. The dsi register offsets of the exynos5422 are similar with exynos5433. However, the values of the registers are quite different from the exynos5433. For example, the exynos5422 uses sw reset like previous chips.

2016-12-14[media] rc: ir-spi: add support for IR LEDs connected with SPIAndi Shyti
The ir-spi is a simple device driver which supports the connection between an IR LED and the MOSI line of an SPI device. The driver, indeed, uses the SPI framework to stream the raw data provided by userspace through a character device. The chardev is handled by the LIRC framework and its functionality basically provides: - raw write: data to be sent to the SPI and then streamed to the MOSI line; - set frequency: sets the frequency whith which the data should be sent; - set length: sets the data length. This information is optional, if the length is set, then userspace should send raw data only with that length; while if the length is set to '0', then the driver will figure out himself the length of the data based on the length of the data written on the character device. The latter is not recommended, though, as the driver, at any write, allocates and deallocates a buffer where the data from userspace are stored. The driver provides three feedback commands: - get length: reads the length set and (as mentioned), if the length is '0' it will be calculated at any write - get frequency: the driver reports the frequency. If userpace doesn't set the frequency, the driver will use a default value of 38000Hz. The character device is created under /dev/lircX name, where X is and ID assigned by the LIRC framework. Example of usage: int fd, ret; ssize_t n; uint32_t val = 0; fd = open("/dev/lirc0", O_RDWR); if (fd < 0) { fprintf(stderr, "unable to open the device\n"); return -1; } /* ioctl set frequency and length parameters */ val = 6430; ret = ioctl(fd, LIRC_SET_LENGTH, &val); if (ret < 0) fprintf(stderr, "LIRC_SET_LENGTH failed\n"); val = 608000; ret = ioctl(fd, LIRC_SET_FREQUENCY, &val); if (ret < 0) fprintf(stderr, "LIRC_SET_FREQUENCY failed\n"); /* read back length and frequency parameters */ ret = ioctl(fd, LIRC_GET_LENGTH, &val); if (ret < 0) fprintf(stderr, "LIRC_GET_LENGTH failed\n"); else fprintf(stdout, "legnth = %u\n", val); ret = ioctl(fd, LIRC_GET_FREQUENCY, &val); if (ret < 0) fprintf(stderr, "LIRC_GET_FREQUENCY failed\n"); else fprintf(stdout, "frequency = %u\n", val); /* write data to device */ n = write(fd, b, 6430); if (n < 0) { fprintf(stderr, "unable to write to the device\n"); ret = -1; } else if (n != 6430) { fprintf(stderr, "failed to write everything, wrote %ld instead\n", n); ret = -1; } else { fprintf(stdout, "written all the %ld data\n", n); } close(fd); The driver supports multi task access, but all the processes which hold the driver should use the same length and frequency parameters.

2016-12-14spi: s3c64xx: add the BROKEN_CS case when setting up the transferAndi Shyti
The CS line might be disconneced ("broken"), therefore unused. In this case, the device doesn't need to wait for the user to handle the CS line for selecting the slave. The data will then be automatically transferred without taking the CS line status into account.

2016-12-14UBSAN: run-time undefined behavior sanity checkerAndrey Ryabinin
UBSAN uses compile-time instrumentation to catch undefined behavior (UB). Compiler inserts code that perform certain kinds of checks before operations that could cause UB. If check fails (i.e. UB detected) __ubsan_handle_* function called to print error message. So the most of the work is done by compiler. This patch just implements ubsan handlers printing errors. GCC has this capability since 4.9.x [1] (see -fsanitize=undefined option and its suboptions). However GCC 5.x has more checkers implemented [2]. Article [3] has a bit more details about UBSAN in the GCC.

2016-12-14cpufreq-dt: add 'boost' mode frequencies supportBartlomiej Zolnierkiewicz
Add 'boost' mode frequencies support: - add boost-opps binding to cpufreq-dt driver bindings - make cpufreq_init() adjust freq_table accordingly - fix set_target() to handle boost frequencies - add boost_supported field to struct cpufreq_dt_platform_data - set dt_cpufreq_driver.boost_supported in dt_cpufreq_probe() This patch makes cpufreq-dt driver aware of 'boost' mode frequencies and prepares it for adding support for Exynos4x12 'boost' support. boost-opps binding is currently limited to cpufreq-dt but once there is a need for cpufreq wide and/or generic Linux device support for 'boost' mode cpufreq-dt can be updated to handle the new code without changing the binding itself. The decision to make 'boost' mode support limited to cpufreq-dt driver for now was taken because 'boost' mode is currently a niche feature and code needed for parsing boost-opps binding is minimal and simple. More generic (i.e. separate 'boost' OPPs list in struct device and generic cpufreq convertion of them to freq_table format) support would need far more code and effort to make it work. Doing it without a demonstrated real need would be on overengineering IMHO.

2016-12-14Smack: limited capability for changing process labelZbigniew Jasinski
This feature introduces new kernel interface: - <smack_fs>/relabel-self - for setting transition labels list This list is used to control smack label transition mechanism. List is set by, and per process. Process can transit to new label only if label is on the list. Only process with CAP_MAC_ADMIN capability can add labels to this list. With this list, process can change it's label without CAP_MAC_ADMIN but only once. After label changing, list is unset. Changes in v2: * use list_for_each_entry instead of _rcu during label write * added missing description in security/Smack.txt Changes in v3: * squashed into one commit Changes in v4: * switch from global list to per-task list * since the per-task list is accessed only by the task itself there is no need to use synchronization mechanisms on it Changes in v5: * change smackfs interface of relabel-self to the one used for onlycap multiple labels are accepted, separated by space, which replace the previous list upon write Signed-off-by: Zbigniew Jasinski <z.jasinski@samsung.com> Signed-off-by: Rafal Krypa <r.krypa@samsung.com> Acked-by: Casey Schaufler <casey@schaufler-ca.com>
2016-12-14Smack: allow multiple labels in onlycapRafal Krypa
Smack onlycap allows limiting of CAP_MAC_ADMIN and CAP_MAC_OVERRIDE to processes running with the configured label. But having single privileged label is not enough in some real use cases. On a complex system like Tizen, there maybe few programs that need to configure Smack policy in run-time and running them all with a single label is not always practical. This patch extends onlycap feature for multiple labels. They are configured in the same smackfs "onlycap" interface, separated by spaces. Signed-off-by: Rafal Krypa <r.krypa@samsung.com>

2016-12-14drm/exynos: mic: add MIC driverHyungwon Hwang
MIC(Mobile image compressor) is newly added IP in Exynos5433. MIC resides between decon and mipi dsim, and compresses frame data by 50%. With dsi, not display port, to send frame data to the panel, the bandwidth is not enough. That is why this compressor is introduced. Signed-off-by: Hyungwon Hwang <human.hwang@samsung.com>
