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>
2008-10-08ARM: OMAP: Fixes to omap_mcbsp_request functionJarkko Nikula
Bootloader may let McBSP logic running so make sure that block is idle before requesting IRQs. Also make sure that TX and RX waitqueues are initialized before request_irq. Signed-off-by: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2008-10-08ARM: OMAP: Allocate McBSP devices dynamicallyChandra Shekhar
Based on Chandra's earlier patches in linux-omap tree. Note that omap1_mcbsp_check and omap2_mcbsp_check are no longer needed as there's now omap_mcbsp_check_valid_id() defined. Also some functions can now be marked __init. Signed-off-by: Chandra Shekhar <x0044955@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2008-10-08Fix sections for omap-mcbsp platform driverUwe Kleine-König
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.
