Convert the corgi backlight driver to a more generic version so it can be reused by other code rather than being Zaurus/PXA specific. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

This patch adds support for powering on and off the Samsung LTV350QV LCD panel via SPI. The driver responds to framebuffer power management, it powers off the panel on reboot/halt/poweroff. It can also be controlled through sysfs. The panel is powered up when the module is loaded, and off when the module is unloaded. Verified on AVR32 STK1000.

Jesper Juhl authored
After fixing the too small memory allocation in cr_backlight_probe() from drivers/video/backlight/cr_bllcd.c (commit e3bbb3f0) I noticed that the Coverity checker also thought there were a few memory leaks in there. I took a closer look and confirmed that there were indeed several leaks. At the start of the function we allocate storage for a 'struct cr_panel' and store the pointer in a variable named 'crp'. Then we call pci_get_device() and pci_read_config_byte() and if either of them fail we return without freeing the memory allocated for the 'struct cr_panel'. These two leaks are easy to fix since we don't even use 'crp' for anything up to this point, so I simply moved the allocation further down in the function so it only happens just before we actually need it. A bit further down we call backlight_device_register() and store the result in 'crp->cr_backlight_device'. In case of error we return 'crp->cr_backlight_device' from the function, thus leaking 'crp' itself. The same thing happens with the call to lcd_device_register(). To fix these two leaks I declare two new pointers to hold the return values, so that in case of error we can return the pointer (as before) but without leaking 'crp'. This version of the patch also adds missing backlight_device_unregister() / lcd_device_unregister() / pci_dev_put() calls to error paths. Thanks to Richard Purdie <rpurdie@rpsys.net> for noticing.

As explained on: http://www.avrfreaks.net/index.php?nameÿphpBB2&fileÿewtopic&tS307 If the current process is preempted before it can copy RAR_SUP and RSR_SUP both register are lost and the process will segfault as soon as it return from the syscall since the return adress will be corrupted. This patch disable IRQ as soon as we enter the syscall path and reenable them when the copy is done. In the interrupt handlers, check if we are interrupting the srrf instruction, if so disable interrupts and return. The interrupt handler will be re-called immediatly when the interrupts are reenabled. After some stressing workload: - find / > /dev/null in loop - top (in ssh) - ping -f avr32 The segfaults are not seen anymore.

The implementation of __builtin_xchg() in at least some versions of avr32 gcc is buggy. Rather than find out exactly which versions that have this bug, let's just avoid the problem altogether by implementing xchg() in inline assembly. Also, in most architectures, xchg() seems to imply a memory barrier, while the existing avr32 implementation did not. This patch also fixes that discrepancy.

Make the NGW100 bitbang i2c use open drain signaling. Also, speed it up, so it's closer to 100 kHz ... the code paths seem to be long enough that the udelay isn't dominating bit times. The peak bit rate I observed was around 125 kHz, but that's with large delays (usually before ACK/NAK) which hold the overall rate down to around 80 kHz (call it 100 usec/byte on average).

I don't think the dma_sync_*_for_cpu ever did anything useful. We flush the relevant cache lines when mapping the buffer or when calling dma_sync_*_for_device(), and the CPU isn't allowed to touch the buffer after that. In other words, if these functions actually have anything to flush from the caches, we're already in trouble. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

__init_end, which comes immediately before .text, is already page aligned, and that should be more than enough for the .text section. The reason why we need to align the .text section is because the interrupt handler offset is ORed with EVBA, so we need to provide enough alignment of EVBA that this OR operation works as an ADD. Currently, the last interrupt handler is not nearly a full page away from EVBA, so it won't be a problem. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
