* ARM: 6455/2: Better use of the RTC framework for sa11xx.Marcelo Roberto Jimenez2010-12-211-24/+74
| | | | | | | | | | This patch uses the RTC framework to treat some common ioctl. In particular, it fixes the behaviour of rtc_irq_set_freq(), which did not work as expected because the timer was not beeing retriggered.

* ARM: 6447/3: sa1100: Put nanoEngine support back in the kernelMarcelo Roberto Jimenez2010-12-214-13/+142
| | | | | | | | | | | | | | Adds Bright Star Engineering's nanoEngine board support to the kernel. Also: - Adds the nanoEngine memory chip to arch/arm/mach-sa1100/cpu-sa1110.c (Micron MT48LC8M16A2TG-75). - Increase in the sdram_params->name[] field length to accomodate the name of the memory chip. - Clean up of header content and order of arch/arm/mach-sa1100/cpu-sa1110.c Signed-off-by: Marcelo Roberto Jimenez <mroberto@cpti.cetuc.puc-rio.br> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: 6454/1: sa1100: Fix for a nasty initialization bug in the RTSR.Marcelo Roberto Jimenez2010-11-101-1/+41
| | | | | | | | | | | | | | | | | | This patch fixes a nasty initialization condition on the RTSR register. Sometimes, bit 1 will wake up set, sometimes not. This can be seen by checking the value of the RTSR by typing '$ cat /proc/driver/rtc', which has been provided by the previous patch. If this bit is set, the command '$ cat /dev/rtc0' will lock the system in an endless interrupt routine calling loop. This patch fixes the issue both at sa1100_rtc_probe(), where it avoids a spurious interrupt from happening, and at sa1100_rtc_interrupt(), which is the robust solution, though it does not avoid the first spurious interrupt.

The driver deals with much shorter times (<200ms). This will fix a rare division by zero bug in Mode1. This could happen, when the work is not executed in time (within mode1_latency) after the interrupt. In this case the DAC33 will not receive the needed nSample command in time, and enters to an unknown state, and won't recover. In such event the time window will increase, and eventually going to be bigger than 1s, resulting devision by zero.

There is just one LED on the device. The LED can either be On or it can be set to Blink. There doesn't seem to be a way to switch it off. The control message to change LED status is similar to that of audigy2nx except that the index is to be set to 0 and value is 1 for Blink and 0 for On. The 'Power LED' control in alsamixer when muted will cause the LED to Blink continuously. When unmuted the LED will stay On. The Creative driver under Windows sets the LED to blink whenever audio is muted. This LED can be treated as the CMSS LED but I figured since there is just one LED, it should be treated as the Power LED. Is that alright? I've also changed the comment "Usb X-Fi" to "Usb X-Fi S51" as there are other external X-Fi devices from Creative like Usb X-Fi Go and Xmod. The volume knob and LED support patch doesn't apply to them. Signed-off-by: Mandar Joshi <emailmandar@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

It seems to me that we don't always free the various memory buffers we allocate and we also do some work (structure member assignment) early, that is completely pointless if some of the memory allocations fail and we end up just aborting the whole thing. I don't have hardware to test, so the patch below is compile tested only, but it makes the following changes: - Make sure we always free all allocated memory on failures. - Don't do pointless work assigning to structure members before we know all memory allocations, that may abort progress, have completed successfully. - Remove some trailing whitespace.

The convention is intended to reduce text usage by sharing the common bits of the string, but the implementation is inherently fragile (a change to one format string but not the other will nullify any possible advantage), it isn't necessarily a net win depending on what this compiler does, and it it reduces code readability.

| * | | | spi/bfin_spi: only request GPIO on first loadMichael Hennerich2010-10-221-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gpiolib code does not allow people to do gpio_request() on a GPIO once it has already been requested. So make sure we only request the pin on the first setup of a SPI device. Otherwise, if you attempts to reconfigure a SPI device on the fly (like change bit sizes), the setup function incorrectly fails.

| * | | | spi/bfin_spi: handle error/status changes after data interruptsMichael Hennerich2010-10-221-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error interrupt on the BF537 SIC cannot be enabled on a per-peripheral basis. Once the error interrupt is enabled for one peripheral, it is automatically enabled for all. So in the Blackfin on-chip SPI driver, we need to clear out these known errors in the data interrupt once we've successfully finished processing all of the pending data.

| * | | | spi: enable spi_board_info to be registered after spi_masterFeng Tang2010-10-212-41/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently spi_register_board_info() has to be called before its related spi_master be registered, otherwise these board info will be just ignored. This patch will remove this order limit, it adds a global spi master list like the existing global board info listr. Whenever a board info or a spi_master is registered, the spi master list or board info list will be scanned, and a new spi device will be created if there is a master-board info match.
