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.

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.

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: NRussell King <rmk+kernel@arm.linux.org.uk>

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.

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: NMisael Lopez Cruz <x0052729@ti.com> Signed-off-by: NTony Lindgren <tony@atomide.com>

Don't use __init but __devinit to define probe function. A pointer to omap_mcbsp_probe is passed to the core via platform_driver_register and so the function must not disappear when the init code is freed. Using __init and having HOTPLUG=y the following probably oopses: echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/unbind echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/bind While at it move the remove function to the .devexit.text section.
