* s3c-fb: add support for display panningPawel Osciak2010-08-11
| | | | | | | | | | | | | | | | | | Supports all bpp modes. The PRTCON register is used to disable in-hardware updates of registers that store start and end addresses of framebuffer memory. This prevents display corruption in case we do not make it before VSYNC with updating them atomically. With this feature there is no need to wait for a VSYNC interrupt before each such update.

* s3c-fb: fix various null references on framebuffer memory alloc failurePawel Osciak2010-08-11
| | | | | | | | | | | | | | | | | | | | The following problems were found in the above situation: sfb->windows[win] was being assigned at the end of s3c_fb_probe_win only. This resulted in passing a NULL to s3c_fb_release_win if probe_win returned early and a memory leak. dma_free_writecombine does not allow its third argument to be NULL. fb_dealloc_cmap does not verify whether its argument is not NULL.

| | | | | | | | | | | | | | | | | | As sysfs_notify_dirent has been made irq safe, there is no reason to not call it directly from irq. With the work_struct removed, the remaining element in poll_desc is a sysfs_dirent pointer which may not be NULL. We can therefore store it directly in the idr and pass it as context to the irq handler. Most part of the patch deals with renaming defines and variables to reflect their new use without functional change. I also took the opportunity to initialize the idr statically.

* gpio: max730x: make pullups configurable via platformdataMarc Kleine-Budde2010-08-11
| | | | | | | | | | | | | | | | | | | | | The gpios on the max730x chips have support for internal pullups while in input mode. This patch adds support for configuring these pullups via platform data. A new member ("input_pullup_active") to the platform data struct is introduced. A set bit in this variable activates the pullups while the respective port is in input mode. This is a compatible enhancement since unset bits lead to disables pullups which was the default in the original driver. _Note_: the 4 lowest bits in "input_pullup_active" are unused because the first 4 ports of the controller are not used, too.

* rtc: fixes and new functionality for fm3130Sergey Matyukevich2010-08-11
| | | | | | | | | | | | | | | | | | | | | | | | - add sanity check for alarm data in fm3130_probe - fix fm3130_set_alarm. According to the datasheet, setting match bit '0' indicates that the corresponding alarm field will be used in the match process - add operation alarm_irq_enable operation which is responsible for handling RTC_AIE_ON, RTC_AIE_OFF ioctls - remove clearing of AF bit after reading rtc/alarm control register: according to datasheet this bit is cleared anyway when rtc/alarm control register is read [akpm@linux-foundation.org: make fm3130_alarm_irq_enable() static, fix comment layout] Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com> Acked-by: Wan ZongShun <mcuos.com@gmail.com> Acked-by: Sergey Lapin <slapin@ossfans.org> Cc: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* rtc/nuc900: fix checking of args during time-settingWan ZongShun2010-08-11
| | | | | | | | | | | | | | When a user application wants to set the rtc time, the RTC subsystem takes advantage of 'rtc_valid_tm(tm)' to check 'rtc_time *tm' value validity, it make sure the 'tm->tm_year' is larger than 70,so if '70< tm_year < 100', the '(settm->tm_year - 100)' will be negative. ' Setting the negative value to hardware register will be invalid, so I add the 'if' condition to make sure set a valid value to register.

* nuc900/rtc: change the waiting for device ready implementWan ZongShun2010-08-11
| | | | | | | | | | | | | | | - add an mdelay(1) to the polling loop to cause less frequent access to the hardware register. - change the return value from ENODEV to EPERM if the loop timed out. I think the 'Operation not permitted' description is more suitable for the meaning of 'check_rtc_access_enable()' function, it just be used to judge rtc access operation is permitted or not.
