* msm: fix compile failure when no debug uart is selectedDaniel Walker2010-10-29
| | | | | | | | | | | | | | | | | | | If the board has a debug uart the user is given a choice of which uart to use. The user can also select NONE, which means not to use one. In most of our header files when NONE is selected nothing is defined for MSM_DEBUG_UART_PHYS or MSM_DEBUG_UART_BASE. This causes a compile failure in debug-macro.S which expect something to be defined there. Example of the failure, arch/arm/kernel/built-in.o: In function `hexbuf': linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_PHYS' linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_BASE' This fixes the compile failure by adding an ifdef to debug-macro.S that removes all the debug uart code in the case of NONE.

* msm: fix debug-macro.S build failureDaniel Walker2010-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | Originally there was an ifdef case to handle when no debug uart was selected. In commit 0ea1293009826da45e1019f45dfde1e557bb30df that case was removed which causes the following build failure, linux-2.6/arch/arm/kernel/debug.S: Assembler messages: linux-2.6/arch/arm/kernel/debug.S:174: Error: bad instruction `addruart r1,r2' linux-2.6/arch/arm/kernel/debug.S:176: Error: bad instruction `waituart r2,r3' linux-2.6/arch/arm/kernel/debug.S:177: Error: bad instruction `senduart r1,r3' linux-2.6/arch/arm/kernel/debug.S:178: Error: bad instruction `busyuart r2,r3' linux-2.6/arch/arm/kernel/debug.S:190: Error: bad instruction `addruart r1,r2' This is a partial revert to add back the case which was removed with two caveats. First the API for the addruart macro was updated, and the new addruart case now return 0xfff00000 so that a know IO mapping is created instead of a random one.

* arm: return both physical and virtual addresses from addruartJeremy Kerr2010-10-20
| | | | | | | | | | | | | | | | | | | | Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the 'gpiomux' api, which addresses the following shortcomings of existing tlmm api: - gpio power-collapse, which is managed by a peripheral processor on other targets, must be managed by the application processor on the 8x60. - The enable/disable flag of the legacy gpio_tlmm_config api is not applicable on the 8x60, and causes confusion. - The gpio 'direction' bits are meaningless for all func_sel configurations except for generic-gpio mode (func_sel 0), in which case the gpio_direction_* functions should be used. Having these bits in the tlmm api leads to confusion and misuse of the gpiolib api, and they have been removed in gpiomux. - The functional api of the legacy system ran contrary to the typical use-case, which is a single massive configuration at boot. Rather than forcing hundreds of 'config' function calls, the new api allows data to be configured with a single table. gpiomux_get and gpiomux_put are meant to be called automatically when gpio_request and gpio_free are called, giving automatic gpiomux/tlmm control to those drivers/lines with simple power profiles - in the simplest cases, an entry in the gpiomux table and the correct usage of gpiolib is all that is required to get proper gpio power control.

* | ARM: do not define VMALLOC_END relative to PAGE_OFFSETNicolas Pitre2010-10-01
|/ | | | | | | | | | | VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may vary depending on the selected user:kernel memory split mode through CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to accommodate more directly addressed RAM by the kernel below the vmalloc area, and having VMALLOC_END move along PAGE_OFFSET is rather against the very reason why PAGE_OFFSET can be moved in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch from Brent DeGraaf: "The datamover supports channels which can be shared amongst devices. As a result, the actual data transfer may occur some time after the request is queued up. Some devices such as mmc host controllers will timeout if a command is issued too far in advance of the actual transfer, so if dma to other devices on the same channel is already in progress or queued up, the added delay can cause pending transfers to fail before they start. This change extends the api to allow a user callback to be invoked just before the actual transfer takes place, thus allowing actions directly associated with the dma transfer, such as device commands, to be invoked with precise timing. Without this mechanism, there is no way for a driver to realize this timing. Also adds a user pointer to the command structure for use by the caller to reference information that may be needed by the callback routine for proper identification and processing associated with that specific request. This change is necessary to fix problems associated with excessive command timeouts and race conditions in the mmc driver." This patch also fixes all the callers of msm_dmov_enqueue_cmd() to ensure their callback function is NULL.
