2009-02-08[ARM] omap: mcbsp: convert to use fck/ick clocks directlyRussell King1-26/+0
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.Miao1-120/+25
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.

2008-10-08ARM: OMAP: Allocate McBSP devices dynamicallyChandra Shekhar1-16/+12
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>
