| * OMAPDSS: Provide an interface for audio supportRicardo Neri2012-05-111-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exist several display technologies and standards that support audio as well. Hence, it is relevant to update the DSS device driver to provide an audio interface that may be used by an audio driver or any other driver interested in the functionality. The audio_enable function is intended to prepare the relevant IP for playback (e.g., enabling an audio FIFO, taking in/out of reset some IP, enabling companion chips, etc). It is intended to be called before audio_start. The audio_disable function performs the reverse operation and is intended to be called after audio_stop. While a given DSS device driver may support audio, it is possible that for certain configurations audio is not supported (e.g., an HDMI display using a VESA video timing). The audio_supported function is intended to query whether the current configuration of the display supports audio. The audio_config function is intended to configure all the relevant audio parameters of the display. In order to make the function independent of any specific DSS device driver, a struct omap_dss_audio is defined. Its purpose is to contain all the required parameters for audio configuration. At the moment, such structure contains pointers to IEC-60958 channel status word and CEA-861 audio infoframe structures. This should be enough to support HDMI and DisplayPort, as both are based on CEA-861 and IEC-60958. The omap_dss_audio structure may be extended in the future if required. The audio_enable/disable, audio_config and audio_supported functions could be implemented as functions that may sleep. Hence, they should not be called while holding a spinlock or a readlock. The audio_start/audio_stop function is intended to effectively start/stop audio playback after the configuration has taken place. These functions are designed to be used in an atomic context. Hence, audio_start should return quickly and be called only after all the needed resources for audio playback (audio FIFOs, DMA channels, companion chips, etc) have been enabled to begin data transfers. audio_stop is designed to only stop the audio transfers. The resources used for playback are released using audio_disable. A new enum omap_dss_audio_state is introduced to help the implementations of the interface to keep track of the audio state. The initial state is _DISABLED; then, the state transitions to _CONFIGURED, and then, when it is ready to play audio, to _ENABLED. The state _PLAYING is used when the audio is being rendered.

| * OMAPDSS: VENC: allow switching venc output type at runtimeGrazvydas Ignotas2012-05-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | VENC output type (composite/svideo) doesn't have to be fixed by board wiring, it is possible to also provide composite signal through svideo luminance connector (software enabled), which is what pandora does. Having to recompile the kernel for users who have TV connector types that don't match default board setting is very inconvenient, especially for users of a consumer device, so add support for switching VENC output type at runtime over a new sysfs file output_type.

| * | ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architectureViresh Kumar2012-04-221-6/+7
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a generic target for SPEAr3xx machines that can be configured via the device-tree. Currently the following devices are supported via the devicetree: - VIC interrupts - PL011 UART - PL061 GPIO - PL110 CLCD - SP805 WDT - Synopsys DW I2C - Synopsys DW ethernet - ST FSMC-NAND - ST SPEAR-SMI - ST SPEAR-KEYBOARD - ST SPEAR-RTC - ARASAN SDHCI-SPEAR - SPEAR-EHCI - SPEAR-OHCI Other peripheral devices will follow in later patches. This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of 4K for individual peripherals. This is done to have efficient TLB lookup for any I/O windows that are located closely together. ioremap() on this range will return this mapping only instead of creating another.

* ARM: move iotable mappings within the vmalloc regionNicolas Pitre2011-11-261-6/+5
| | | | | | | | | | | | | | | | | | | In order to remove the build time variation between different SOCs with regards to VMALLOC_END, the iotable mappings are now allocated inside the vmalloc region. This allows for VMALLOC_END to be identical across all machines. The value for VMALLOC_END is now set to 0xff000000 which is right where the consistent DMA area starts. To accommodate all static mappings on machines with possible highmem usage, the default vmalloc area size is changed to 240 MB so that VMALLOC_START is no higher than 0xf0000000 by default.

* | ARM: 6999/1: head, zImage: Always Enter the kernel in ARM stateDave Martin2011-07-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the documented kernel entry requirements are not explicit about whether the kernel should be entered in ARM or Thumb, leading to an ambiguitity about how to enter Thumb-2 kernels. As a result, the kernel is reliant on the zImage decompressor to enter the kernel proper in the correct instruction set state. This patch changes the boot entry protocol for head.S and Image to be the same as for zImage: in all cases, the kernel is now entered in ARM. Documentation/arm/Booting is updated to reflect this new policy. A different rule will be needed for Cortex-M class CPUs as and when support for those lands in mainline, since these CPUs don't support the ARM instruction set at all: a note is added to the effect that the kernel must be entered in Thumb on such systems.

* Documentation: update broken web addresses.Justin P. Mattock2010-08-0412-22/+19
| | | | | | | | | | | | | | | | | | Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

* ARM: 6225/1: make TCM allocation static and common for all archsLinus Walleij2010-07-272-12/+26
| | | | | | | | | | | | | | | | This changes the TCM handling so that a fixed area is reserved at 0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but XScale does not have TCM so the mechanisms are mutually exclusive. This change is needed to make TCM detection more dynamic while still being able to compile code into it, and is a must for the unified ARM goals: the current TCM allocation at different places in memory for each machine would be a nightmare if you want to compile a single image for more than one machine with TCM so it has to be nailed down in one place.
