* bcm2835: introduce mach-bcm283xAlexander Aring2016-01-042-5/+5
| | | | | | | | | | | | This patch changes the most part of mach-bcm2835 to mach-bcm283x. This prepares to add RPi2 support which is a bcm2836. This patch changes the Kconfig entry namens to BCM283X for drivers only. These drivers should working the same in bcm2836. While updating defconfig I added LED support/trigger option.

| * video: i.MX IPUv3: Set ldb clocks correctlySascha Hauer2015-11-301-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | The clocks for the LVDS display bridge have a fixed /3.5 and a configurable /1,/2 divider in their path. The configurable divider has to be explicitly configured for single/dual channel support, so we can't rely on clock rate parent propagation here. Clear the CLK_SET_RATE_PARENT flag for the configurable divider and configure the clock explicitly in the ldb driver. Tested on a custom i.MX6 board, currently untested on i.MX53.

| | | | | | | | | | | | | | | | | | If probed from device tree we have an array of pwm duty cycle levels in the brightness-levels property. Although the driver parsed the property, the values have been ignored. Make use of these flags so that the driver can work for example with inverted PWMs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | rework remap_rangeSascha Hauer2015-11-033-9/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | remap_range is for remapping regions with different cache attributes. It is implemented for ARM and PowerPC only, the other architectures only provide stubs. Currently the new cache attributes are passed in an architecture specific way and the attributes have to be retrieved by calls to mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags(). Make this simpler by providing architecture independent flags which can be directly passed to remap_range() Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function. The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture has as default. the arch_can_remap() function returns true if the architecture can change the cache attributes, false otherwise. This allows the memtest code to better find out what it has to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This does not work properly when two users (splash and fbconsole) use the same framebuffer since in this case two different shadow framebuffers will be used. This patch implements shadowfb handling in the fb core directly. With this the fb device gets a parameter 'shadowfb'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complex video pipelines are modelled with the of_graph bindings in the devicetree. This patch adds a ioctl infrastructure to issue commands to the remote endpoint of a of_graph. Currently defined ioctls are prepare/unprepare, enable/disable and get_modes. This is enough to control LVDS or HDMI encoder or simple panels. A device node which contains of_graph endpoints can be registered as a VPL entity. An entity can receive ioctls via the .ioctl callback and also issue ioctls by calling vpl_ioctl. The core itself will never iterate over the entire pipeline. Instead, the different VPL entities should forward an ioctl to the next instance in the pipeline whenever necessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
