* omap mmc: Add better MMC low-level initTony Lindgren2008-12-10
| | | | | | | | | | | | | | | | | | | | | | This will simplify the MMC low-level init, and make it more flexible to add support for a newer MMC controller in the following patches. The patch rearranges platform data and gets rid of slot vs controller confusion in the old data structures. Also fix device id numbering in the clock code. Some code snippets are based on an earlier patch by Russell King <linux@arm.linux.org.uk>. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Tony Lindgren <tony@atomide.com>
* omap mmc: Remove broken MMC init codeTony Lindgren2008-12-10
| | | | | | | | | | | | | Most of the omap1 MMC boards got broken by an earlier patch 138ab9f8321f67c71984ca43222efa71b0a0a0a9. If you look closely, the MMC init funtions are pretty much just stubs. Remove broken init code to make room for cleaner MMC init code. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP3: Warn about spurious interruptsTony Lindgren2008-12-10
| | | | | | | | | In the case of spurious interrupt, the handler for previous interrupt handler needs to flush posted writes with a read back of the interrupt ack register. Warn about handlers that need to flush posted writes. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2: skip unnecessary TLDR write during non-autoreload for gptimerPaul Walmsley2008-12-10
| | | | | | | | | | | | | | | | | | | | | | The GPTIMER TLDR register does not need to be written if the GPTIMER is not in autoreload mode. This is the usual case for dynamic tick-enabled kernels. Simulation data indicate that skipping the read that occurs as part of the write should save at least 300-320 ns for each GPTIMER1 timer reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write posting is enabled.) Skipping the write itself probably won't have much impact since it should be posted on the OCP interconnect. Tested on 2430SDP and 3430SDP.

* ARM: OMAP: switch to gpio_direction_outputDavid Brownell2008-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | More conversion to the standard GPIO interfaces: stop using omap_set_gpio_direction() entirely, and switch over to the gpio_direction_output() call. Note that because gpio_direction_output() includes the initial value, this change isn't quite transparent. - For the call sites which defined an initial value either before or after setting the direction, that value was used. When that value was previously assigned afterwards, this could eliminate a brief output glitch ... and possibly change behavior. In a few cases (LCDs) several values were assigned together ... those were re-arranged to match the explicit sequence provided. - Some call sites didn't define such a value; so I chose an initial "off/reset" value that seemed to default to "off". In short, files touched by this patch might notice some small changes in startup behavior (with trivial fixes).

| | | | | | | | | | | | | | | | This patch replaces some legacy OMAP GPIO calls with the "new" (not really, any more!) calls that work on most platforms. The calls addressed by this patch are the simple ones to get and set values ... for code that's in mainline, including the implementations of those calls. Except for the declarations and definitions of those calls, all of these changes were performed by a simple SED script. Plus, a few "if() set() else set()" branches were merged by hand.

* ARM: OMAP: Enable GPIO debounce clock only when debounce is enabled v3Jouni Hogander2008-12-10
| | | | | | | | | | | | | | | | | | | This patch changes gpio "driver" to enable debounce clock for gpio-bank only when debounce is enabled for some gpio in that bank. Gpio functional clocks are also renamed in clock tree, gpioX_fck -> gpioX_dbck. This patch triggers problem with gpio wake-up and Omap3. Gpios in PER domain aren't capable to generate wake-up if PER domain is in sleep state. For this iopad wake-up should be used and needed pad configuration should be done. Enabling iopad wake-up for gpio pads is left for bootloader or omap mux configuration in kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARMv6 and later CPUs, it is possible for userspace processes to get stuck on a misaligned load or store due to the "ignore fault" setting; unlike previous CPUs, retrying the instruction without the 'A' bit set does not always cause the load to succeed. We have no real option but to default to fixing up alignment faults on these CPUs, and having the CPU fix up those misaligned accesses which it can.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8ec53663d2698076468b3e1edc4e1b418bd54de3 ("[ARM] Improve non-executable support") added support for detecting non-executable stack binaries. One of the things it does is to make READ_IMPLIES_EXEC be set in ->personality if we are running on a CPU that doesn't support the XN ("Execute Never") page table bit or if we are running a binary that needs an executable stack. This exposed a latent bug in ARM's asm/processor.h due to which we'll end up placing the stack at a very low address, where it will bump into the heap on any application that uses significant amount of stack or heap or both, causing many interesting crashes. Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead of testing for equality against PER_LINUX_32BIT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0c65f459ce6c intended to fix truncation issues with fls() on ARMv5+ by renaming it to __fls() and wrapping it into a C function. However that didn't take into account the fact that __fls() already already had different semantics in the kernel. Let's move the __fls() code into fls() function directly, and redefine __fls() with the appropriate semantics. While at it, bring a generic __fls() definition for pre ARMv5 too.
