| * ARM: OMAP: get rid of OMAP_TAG_USB, v2Felipe Balbi2009-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP_TAGS should vanish soon since they're not generic arm tags. Most of them can be converted to a platform_data or parsed from a command line like e.g. serial tag. For OMAP_TAG_USB we just let boards call omap_usb_init() passing a pointer to omap_usb_config. Patch updated by Tony for mainline, basically make n770 and h4 compile. Also folded in a fix for OSK by David Brownell <dbrownell@users.sourceforge.net>.

| * ARM: OMAP: Dispatch only relevant DMA interruptsSantosh Shilimkar2009-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the spurious interrupt issue on a DMA channel. In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers. Since there are four sDMA interrupt lines and if more than one line is actively used by two concurrently running sDMA softwares modules,then the spurious interrupt can be observed on the other lines. Fix in this patch will only dispatch the relevant and enabled interrupts on a particular line thus perevting spurious IRQ.

| * ARM: OMAP: Get available DMA channels from cmdlineSantosh Shilimkar2009-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch set up a cmdline option for omap dma for masking the available channels. It is needed since the OMAP DMA is a system wide resource and can be used by another software apart from the kernel. To reserve the omap SDMA channels for kernel dma usage, use cmdline bootarg "omap_dma_reserve_ch=". The valid range is 1 to 32.

| * ARM: OMAP: Add method to register additional I2C busses on the command line, v2Jarkko Nikula2009-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends command line option "i2c_bus=bus_id,clkrate" so that it allow to register additional I2C busses that are not registered with omap_register_i2c_bus from board initialization code. Purpose of this is to register additional board busses which are routed to external connectors only without any on board I2C devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new command line option "i2c_bus=bus_id,clkrate" into I2C bus registration helper. Purpose of the option is to override the default board specific bus speed which is supplied by the omap_register_i2c_bus. The default bus speed is typically set to speed of slowest I2C chip on the bus and overriding allow to use some experimental configurations or updated chip versions without any kernel modifications.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a machine class has a custom __virt_to_bus() implementation then it must provide a __arch_page_to_dma() implementation as well which is _not_ based on page_address() to support highmem. This patch fixes existing __arch_page_to_dma() and provide a default implementation otherwise. The default implementation for highmem is based on __pfn_to_bus() which is defined only when no custom __virt_to_bus() is provided by the machine class. That leaves only ebsa110 and footbridge which cannot support highmem until they provide their own __arch_page_to_dma() implementation. But highmem support on those legacy platforms with limited memory is certainly not a priority. Signed-off-by: Nicolas Pitre <nico@marvell.com>

The sched_clock() frequency should not be adjusted. The patch deletes omap_32k_ticks_to_nsecs() and rewrites sched_clock() to do the conversion using the constant multiplier.

* | [ARM] pass reboot command line to arch_reset()Russell King2009-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

* | [ARM] omap: add support for bypassing DPLLsRussell King2009-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This roughly corresponds with OMAP commits: 7d06c48, 3241b19, 88b5d9b, 18a5500, 9c909ac, 5c6497b, 8b1f0bd, 2ac1da8. For both OMAP2 and OMAP3, we note the reference and bypass clocks in the DPLL data structure. Whenever we modify the DPLL rate, we first ensure that both the reference and bypass clocks are enabled. Then, we decide whether to use the reference and DPLL, or the bypass clock if the desired rate is identical to the bypass rate, and program the DPLL appropriately. Finally, we update the clock's parent, and then disable the unused clocks. This keeps the parents correctly balanced, and more importantly ensures that the bypass clock is running whenever we reprogram the DPLL. This is especially important because the procedure for reprogramming the DPLL involves switching to the bypass clock. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | [ARM] omap: arrange for clock recalc methods to return the rateRussell King2009-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | linux-omap source commit 33d000c99ee393fe2042f93e8422f94976d276ce introduces a way to "dry run" clock changes before they're committed. However, this involves putting logic to handle this into each and every recalc function, and unfortunately due to the caching, led to some bugs. Solve both of issues by making the recalc methods always return the clock rate for the clock, which the caller decides what to do with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
