* fb: add support for foreign endiannessAnton Vorontsov2008-04-289-131/+193
| | | | | | | | | | | | | | | | | | | | Add support for the framebuffers with non-native endianness. This is done via FBINFO_FOREIGN_ENDIAN flag that will be used by the drivers. Depending on the host endianness this flag will be overwritten by FBINFO_BE_MATH internal flag, or cleared. Tested to work on MPC8360E-RDK (BE) + Fujitsu MINT framebuffer (LE).

* fbdev: make the best-fit section of fb_find_mode return the closest matching ↵Michal Januszewski2008-04-281-8/+16
| | | | | | | | | | | | | | | | | | | | mode Currently, if a perfect match in terms of resolution is not found, fb_find_mode() only looks for a best-fit mode among modes with a higher resolution than the one requested. Thus, if the user requests a resolution higher than the largest supported one, they are dropped to the default mode (usually a low resolution one). Change this behaviour so that all valid video modes are considered when looking for a best-fit mode, while still preferring modes with a higher resolution.

* gpiochip_reserve()Anton Vorontsov2008-04-281-3/+47
| | | | | | | | | | | | | | Add a new function gpiochip_reserve() to reserve ranges of gpios that platform code has pre-allocated. That is, this marks gpio numbers which will be claimed by drivers that haven't yet been loaded, and thus are not available for dynamic gpio number allocation.

* gpiolib: dynamic gpio number allocationAnton Vorontsov2008-04-281-7/+45
| | | | | | | | | | | | | | | | If gpio_chip->base is negative during registration, gpiolib performs dynamic base allocation. This is useful for devices that aren't always present, such as GPIOs on hotplugged devices rather than mainboards. (This behavior was previously specified but not implemented.) To avoid using any numbers that may have been explicitly assigned but not yet registered, this dynamic allocation assigns GPIO numbers from the biggest number on down, instead of from the smallest on up.

* gpiolib: better rmmod infrastructureGuennadi Liakhovetski2008-04-281-3/+12
| | | | | | | | | | | | | | | | | As long as one or more GPIOs on a gpio chip are used its driver should not be unloaded. The existing mechanism (gpiochip_remove failure) doesn't address that, since rmmod can no longer be made to fail by having the cleanup code report errors. Module usecounts are the solution. Assuming standard "initialize struct to zero" policies, this change won't affect SOC platform drivers. However, drivers for external chips (on I2C and SPI busses) should be updated if they can be built as modules.

| | | | | | | | | | | | | | | | | | | | | | | | Updates to the i.MX SPI controller driver: 1) Some comments changed and/or added. 2) End of transfers is now managed on TXFIFO empty interrupt after the last write to TXFIFO. This speeds interrupt execution by removing the wait for TXFIFO to become empty. On TXFIFO empty interrupt the handler needs only to poll for the end of the ongoing transaction (SPI_CONTROL_XCH) to close the transfer. (2.1) Write only transfers are closed flushing RXFIFO. (2.2) Read transfers are closed reading trailing bytes from RXFIFO. (2.3) Read transfers where RXFIFO overrun occurred are closed by flushing RXFIFO and aborting the message. 3) Fifos are now flushed via SPI disable after the end of ongoing transaction.

* serial 8250: tighten test for using backup timerAlex Williamson2008-04-281-2/+3
| | | | | | | | | | | | | | | | | | | | Thomas Koeller had reported an issue where a device that had been making use of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by the backup timer test, causing the device to work improperly. To fix this, tighten the test requirements to enable the backup timer workaround. The backup timer is really meant to catch UARTs that don't re-assert the THRE interrupt. The expectation is that they do initially assert THRE. This patch clarifies the test.

* return pfn from direct_access, for XIPJared Hulbert2008-04-282-5/+8
| | | | | | | | | | | | | | | | | | | | | Alter the block device ->direct_access() API to work with the new get_xip_mem() API (that requires both kaddr and pfn are returned). Some architectures will not do the right thing in their virt_to_page() for use by XIP (to translate from the kernel virtual address returned by direct_access(), to a user mappable pfn in XIP's page fault handler. However, we can't switch it to just return the pfn and not the kaddr, because we have no good way to get a kva from a pfn, and XIP requires the kva for its read(2) and write(2) handlers. So we have to return both.

| | | | | | | | | | | | | | | | | | | | | | In current kernel if we want to set the alarm time, the absolute time the seconds relative to 1970-01-01 00:00:00) should be written into /sys/class/rtc/rtc0/wakealarm. It is not convenient. It is more reasonable to add the support for the alarm time relative to current RTC time.(the unit is second) For example: If the RTC is required to generate alarm after 2 minutes, the following will be OK. echo +120 > /sys/class/rtc/rtc0/wakealarm or echo +0x78 > /sys/class/rtc/rtc0/wakealarm Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> 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: avoid legacy drivers with generic frameworkDavid Brownell2008-04-282-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Kconfig tweaks to help reduce RTC configuration bugs, by avoiding legacy RTC drivers when the generic RTC framework is enabled: - If rtc-cmos is selected, disable the legacy rtc driver; - When using generic RTC on x86, enable rtc-cmos by default; - In the old "chardev RTC" section of Kconfig, add a comment warning people off these (seven) legacy RTC drivers when the generic framework is in use. People can still use the legacy drivers if they want (or need) to. This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver. Ideally it would be a full list of platforms where it works, not a partial list of ones where it won't. Or better yet, it would depend on a "HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a Kconfig style guideline lurking there.
