[media] exynos4-is: Allow colorspace conversion at FIMC-LITE The FIMC-LITE output DMA allows to configure different YUV order than the order at the camera input interface. Thus there is some limited colorspace conversion possible. This patch makes the color format variable be per FIMC-LITE input/output, rather than a global per device. This also fixes incorrect behavior where color format at the FIMC-LITE.N subdev's source pad is modified by VIDIOC_S_FMT ioctl on the related video node. YUV order definitions are corrected so that we use notation: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

media: use the BIT() macro As warned by cppcheck: [drivers/media/dvb-frontends/cx24123.c:434]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour [drivers/media/pci/bt8xx/bttv-input.c:87]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour [drivers/media/pci/bt8xx/bttv-input.c:98]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour ... [drivers/media/v4l2-core/v4l2-ioctl.c:1391]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour There are lots of places where we're doing 1 << 31. That's bad, as, depending on the architecture, this has an undefined behavior. The BIT() macro is already prepared to handle this, so, let's just switch all "1 << number" macros by BIT(number) at the header files with has 1 << 31.

[media] exynos4-is: Add Exynos5250 SoC support to fimc-lite driver This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE IP. A 'compatible' string is added for Exynos5250 compatible devices and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ register, masking output DMA buffer address slots. The frame interrupt is enabled so there are now 2 interrupts per frame. This likely can be optimized in future by using any status registers that allow to figure out what the last and the currently written frame buffer is. It would also be more reliable in cases where there are high interrupt service latencies.
