* [ARM] 5509/1: ep93xx: clkdev enable UARTSHartley Sweeten2009-05-162-9/+65
| | | | | | | | | | | | | | | | | | | Fix the clkdev API support for the ep93xx uart clocks. The uarts available in the ep93xx have individual clock controls. The current implementation assumes that the bootloader has enabled the clocks before the kernel has booted. It also assumes that the bootloader has set the UARTBAUD bit indicating that the uarts are running off the 14.7456MHz external crystal. This fixes both issues. It also allows the uart clocks to be stopped when there are no users.

* | [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

* [ARM] 5324/2: ep93xx: support gpio interrupt debounceHartley Sweeten2008-12-012-0/+20
| | | | | | | | | | | | | | | | Add debounce support for ep93xx gpio interrupts. On the EP93xx, GPIO ports A, B, and F can be used to generate interrupts. For each port, if interrupts are enabled, it is possible to debouce the input signal. Debouncing is implemented by passing the input signal through a 2-bit shift register clocked by a 128Hz clock. This patch adds a platform specific way to enable the debouce feature for these input ports.

* | [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-291-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

|/ | | | | | | | | | | | | | | | Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently on the EP93xx platform early kernel messages go to UART1. Since this UART is the only one that has modem control signals it might be used for another purpose and it is undesirable for those messages to appear. This patch allows one of the other UARTs to be selected in the kernel configuration. It is assumed that the bootloader has configured and initialized the UART since this was the previous assumption.

| | * [ARM] 4670/1: ep93xx: implement IRQT_BOTHEDGE gpio irq sense typeHerbert Valerio Riedel2008-01-261-11/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having a both-edge sensitive irq trigger type is required for the generic gpio-keys input driver; alas the ep93xx does not support both-edge gpio triggers in hardware, so this patch implements them by switching edge polarity on each triggered interrupt. This is the same approach as taken by the Orion SoC both-edge gpio irq support implementation.

|/ | | | | | | | | | | Move the xtime write mode seqlock into timer_tick(), so it only surrounds the call to do_timer(). This avoids a deadlock in update_process_times() ... hrtimer_get_softirq_time() which tries to get a read mode seqlock on xtime, thereby preventing booting.
