| * [media] soc_camera: Add the ability to bind regulators to soc_camedra devicesAlberto Panizzo2010-12-30
| | | | | | | | | | | | | | | | | | | | In certain machines, camera devices are supplied directly by a number of regulators. This patch add the ability to drive these regulators directly by the soc_camera driver.

Also removed the header include in radio-si470x.h (not used anymore) and from ioctl-number.txt (it's internal to the kernel and never called from userspace).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remote keytables had different names all over the place. Part of the fault is due to a bad naming when rc subsystem was created, but there were lots of old names that were still here. Use a common standard for everything.

| * [media] ir-kbd-i2c: add rc_dev as a parameter to the driverMauro Carvalho Chehab2010-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | There are several fields on rc_dev that drivers can benefit. Allow drivers to pass it as a parameter to the driver. For now, the rc_dev parameter is optional. If drivers don't pass it, create them internally. However, the best is to create rc_dev inside the drivers, in order to fill other fields, like open(), close(), driver_name, etc. So, a latter patch making it mandatory and changing the caller drivers is welcome.

| * [media] ir-core: make struct rc_dev the primary interfaceDavid Härdeman2010-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges the ir_input_dev and ir_dev_props structs into a single struct called rc_dev. The drivers and various functions in rc-core used by the drivers are also changed to use rc_dev as the primary interface when dealing with rc-core. This means that the input_dev is abstracted away from the drivers which is necessary if we ever want to support multiple input devs per rc device. The new API is similar to what the input subsystem uses, i.e: rc_device_alloc() rc_device_free() rc_device_register() rc_device_unregister() [mchehab@redhat.com: Fix compilation on mceusb and cx231xx, due to merge conflicts] Signed-off-by: David Härdeman <david@hardeman.nu> Acked-by: Jarod Wilson <jarod@redhat.com> Tested-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cx88 only depends on VIDEO_IR because it needs ir_extract_bits(). Move that function to ir-core.h and make it inline. Lots of drivers had dependencies on VIDEO_IR when they really wanted IR_CORE. The only remaining drivers to depend on VIDEO_IR are bt8xx and saa7134 (ir_rc5_timer_end is the only function exported by ir-functions). Rename VIDEO_IR -> IR_LEGACY to give a hint to anyone writing or converting drivers to IR_CORE that they do not want a dependency on IR_LEGACY.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the cx88 driver (for sampling hw) to use the decoders provided by ir-core instead of the separate ones provided by ir-functions (and gets rid of those). The value for MO_DDS_IO had a comment saying it corresponded to a 4kHz samplerate. That comment was unfortunately misleading. The actual samplerate was something like 3250Hz. The current value has been derived by analyzing the elapsed time between interrupts for different values (knowing that each interrupt corresponds to 32 samples).

In the Ux500 we have this for out PrimeCell derivates. This patch makes it possible to specify an (optional) regulator to handle the voltage domain switch on AMBA PrimeCells, modeled very similar to how block clocks are handled. Additional amba_vcore_[enable|disable] calls are supplied to make it possible introduce optional powering off of the core voltage. Using this will require code to spool/unspool any core HW state.

Based on a patch from Linus Walliej, with the following changes: - remove RX DMA support. As PL011 doesn't give us receive timeout interrupts, we only get notified of received data when the RX DMA has completed. This rather sucks for interactive use of the TTY. - remove abuse of completions. Completions are supposed to be for events, not to tell what condition buffers are in. Replace it with a simple 'queued' bool. - fix locking - it is only safe to access the circular buffer with the port lock held. - only map the DMA buffer when required - if we're ever behind an IOMMU this helps keep IOMMU usage down, and also ensures that we're legal when we change the scatterlist entry length. - fix XON/XOFF sending - we must send XON/XOFF characters out as soon as possible - waiting for up to 4095 characters in the DMA buffer to be sent first is not acceptable. - fix XON/XOFF receive handling - we need to stop DMA when instructed to by the TTY layer, and restart it again when instructed to. There is a subtle problem here: we must not completely empty the circular buffer with DMA, otherwise we will not be notified of XON. - change the 'enable_dma' flag into a 'using DMA' flag, and track whether we can use TX DMA by whether the channel pointer is non-NULL. This gives us more control over whether we use DMA in the driver. - we don't need to have the TX DMA buffer continually allocated for each port - instead, allocate it when the port starts up, and free it when it's shut down. Update the 'using DMA' flag if we get the buffer, and adjust the TTY FIFO size appropriately. - if we're going to use PIO to send characters, use the existing IRQ based functionality rather than reimplementing it. This also ensures we call uart_write_wakeup() at the appropriate time, otherwise we'll stall. - use DMA engine helper functions for type safety. - fix init when built as a module - we can't have to initcall functions, so we must settle on one. This means we can eliminate the deferred DMA initialization. - there is no need to terminate transfers on a failed prep_slave_sg() call - nothing has been setup, so nothing needs to be terminated. This avoids a potential deadlock in the DMA engine code (tasklet->callback->failed prepare->terminate->tasklet_disable which then ends up waiting for the tasklet to finish running.) - Dan says that the submission callback should not return an error: | dma_submit_error() is something I should have removed after commit | a0587bcf "ioat1: move descriptor allocation from submit to prep" all | errors should be notified by prep failing to return a descriptor | handle. Negative dma_cookie_t values are only returned by the | dma_async_memcpy* calls which translate a prep failure into -ENOMEM. So remove the error handling at that point. This also solves the potential deadlock mentioned in the previous comment. Acked-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

This is useful for example in architectures where 64-bit ELF vmcores are not supported. Specifying zero vmcore_elf64_check_arch() allows compiler to optimize away unnecessary parts of parse_crash_elf64_headers(). We also rename the macro to vmcore_elf64_check_arch() to reflect that it is used for 64-bit vmcores only.
