2009-10-20omap: headers: Move remaining headers from include/mach to include/platTony Lindgren
Move the remaining headers under plat-omap/include/mach to plat-omap/include/plat. Also search and replace the files using these headers to include using the right path. This was done with: #!/bin/bash mach_dir_old="arch/arm/plat-omap/include/mach" plat_dir_new="arch/arm/plat-omap/include/plat" headers=$(cd $mach_dir_old && ls *.h) omap_dirs="arch/arm/*omap*/ \ drivers/video/omap \ sound/soc/omap" other_files="drivers/leds/leds-ams-delta.c \ drivers/mfd/menelaus.c \ drivers/mfd/twl4030-core.c \ drivers/mtd/nand/ams-delta.c" for header in $headers; do old="#include <mach\/$header" new="#include <plat\/$header" for dir in $omap_dirs; do find $dir -type f -name \*.[chS] | \ xargs sed -i "s/$old/$new/" done find drivers/ -type f -name \*omap*.[chS] | \ xargs sed -i "s/$old/$new/" for file in $other_files; do sed -i "s/$old/$new/" $file done done for header in $(ls $mach_dir_old/*.h); do git mv $header $plat_dir_new/ done Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-10-07OMAP7XX: Rename all the rest of the omap730 references in omap1 coreAlistair Buxton
This patch is part of a series which removes references to omap730 in code which is shared with omap850, replacing them with references to omap7xx. This updates all the remaining omap730 references in miscellaneous local variables, macros and similar. Signed-off-by: Alistair Buxton <a.j.buxton@gmail.com> Reviewed-by: Zebediah C.

2009-08-25ARM: OMAP: McBSP: Merge two functions into omap_mcbsp_start/_stopJarkko Nikula
Functionality of functions omap_mcbsp_xmit_enable and omap_mcbsp_recv_enable can be merged into omap_mcbsp_start and omap_mcbsp_stop since API of those omap_mcbsp_start and omap_mcbsp_stop was changed recently allowing to start and stop individually the transmitter and receiver. This cleans up the code in arch/arm/plat-omap/mcbsp.c and in sound/soc/omap/omap-mcbsp.c which was the only user for those removed functions.

2009-08-07ARM: OMAP: McBSP: Fix ASoC on OMAP1510 by fixing API of omap_mcbsp_start/stopJarkko Nikula
Simultaneous audio playback and capture on OMAP1510 can cause that second stream is stalled if there is enough delay between startup of the audio streams. Current implementation of the omap_mcbsp_start is starting both transmitter and receiver at the same time and it is called only for firstly started audio stream from the OMAP McBSP based ASoC DAI driver. Since DMA request lines on OMAP1510 are edge sensitive, the DMA request is missed if there is no DMA transfer set up at that time when the first word after McBSP startup is transmitted. The problem hasn't noted before since later OMAPs are using level sensitive DMA request lines. Fix the problem by changing API of omap_mcbsp_start and omap_mcbsp_stop by allowing to start and stop individually McBSP transmitter and receiver logics. Then call those functions individually for both audio playback and capture streams. This ensures that DMA transfer is setup before transmitter or receiver is started. Thanks to Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> for detailed problem analysis and Peter Ujfalusi <peter.ujfalusi@nokia.com> for info about DMA request line behavior differences between the OMAP generations.

2009-02-08[ARM] omap: mcbsp: convert to use fck/ick clocks directlyRussell King
Rather than introducing a special 'mcbsp_clk' with code behind it in mach-omap*/mcbsp.c to handle the SoC specifics, arrange for the mcbsp driver to be like any other driver. mcbsp requests its fck and ick clocks directly, and the SoC specific code deals with selecting the correct clock. There is one oddity to deal with - OMAP1 fiddles with the DSP clocks and DSP reset, so we move this to the two callback functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-01-29ARM: OMAP: Fix McBSP spin_lock deadlockStanley.Miao
A spin_lock deadlock will occur when omap_mcbsp_request() is invoked. omap_mcbsp_request() \- clk_enable(mcbsp->clk) [takes and holds clockfw_lock] \- omap2_clk_enable() \- _omap2_clk_enable() \- omap_mcbsp_clk_enable() \- clk_enable(child clock) [tries for clockfw_lock again] mcbsp_clk is a virtual clock and it comprises several child clocks. when enable mcbsp_clk in omap_mcbsp_request(), the enable function of mcbsp_clk will enable its child clocks, then the deadlock occurs. The solution is to remove the virtual clock and enable these child clocks in omap_mcbsp_request() directly.

2009-01-15ARM: OMAP: Fix ASoC by enabling writes to XCCR and RCCR McBSP registers, v3Tony Lindgren
This patch enables writing to McBSP Transmit Configuration Control Register (XCCR) and Receive Configuration Control Register (RCCR) for 2430/34xx platforms. It also adds XCCR, RCCR entries in McBSP register configuration structure and bit definitions for both registers. If we enable the writing to CCR registers for 2430/34xx and don't set the default values (setting 0 as a consequence) in ASoC driver, the Transmit/Receive DMA mode gets disabled and the the transmission/reception doesn't happen, ending with a "write error: Input/Output error" when playing with 'aplay'. Also define dummy CCR registers for omap1. Cc: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Misael Lopez Cruz <x0052729@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
