2009-03-23ARM: OMAP: get rid of OMAP_TAG_USB, v2Felipe Balbi12-23/+15
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.

2009-02-14[ARM] omap: arrange for clock recalc methods to return the rateRussell King2-25/+17
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>
2009-02-08[ARM] omap: create a proper tree of clocksRussell King2-5/+5
Traditionally, we've tracked the parent/child relationships between clk structures by setting the child's parent member to point at the upstream clock. As a result, when decending the tree, we have had to scan all clocks to find the children. Avoid this wasteful scanning by keeping a list of the clock's children.

2009-02-08[ARM] omap: Fix omap1 clock issuesTony Lindgren2-87/+53
This fixes booting, and is a step toward fixing things properly: - Make enable_reg u32 instead of u16 [rmk: virtual addresses are void __iomem *, not u32] - Get rid of VIRTUAL_IO_ADDRESS for clocks - Use __raw_read/write instead of omap_read/write for clock registers This patch adds a bunch of compile warnings until omap1 clock also uses offsets. linux-omap source commit is 9d1dff8638c9e96a401e1885f9948662e9ff9636.

2009-02-08[ARM] omap: spi: arrange for omap_uwire to use connection IDRussell King1-0/+1

2009-02-08[ARM] omap: i2c: remove conditional ick clocksRussell King1-0/+1
By providing a dummy ick for OMAP1510 and OMAP310, we avoid having SoC conditional clock information in i2c-omap.c. Also, fix the error handling by making sure we propagate the error returned via clk_get(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-02-08[ARM] omap: mcbsp: convert to use fck/ick clocks directlyRussell King2-20/+41
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>

2009-02-08[ARM] omap: MMC: convert clocks to match by devid and conidRussell King1-2/+2

2009-02-08[ARM] omap: provide a dummy clock nodeRussell King1-0/+20

2009-02-08[ARM] omap: handle RATE_CKCTL via .set_rate/.round_rate methodsRussell King2-63/+71
It makes no sense to have the CKCTL rate selection implemented as a flag and a special exception in the top level set_rate/round_rate methods. Provide CKCTL set_rate/round_rate methods, and use these for where ever RATE_CKCTL is used and they're not already overridden. This allows us to remove the RATE_CKCTL flag. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-08[ARM] omap: move propagate_rate() calls into generic omap clock codeRussell King1-6/+0
propagate_rate() is recursive, so it makes sense to minimise the amount of stack which is used for each recursion. So, rather than recursing back into it from the ->recalc functions if RATE_PROPAGATES is set, do that test at the higher level. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-08[ARM] omap: remove unnecessary calls to propagate_rate()Russell King1-8/+1
We've always called propagate_rate() in the parent function to the .set_rate methods, so there's no point having the .set_rate methods also call this heavy-weight function - it's mere duplication of what's happening elsewhere. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-08[ARM] omap: move clock propagation into core omap clock codeRussell King1-3/+0
Move the clock propagation calls for set_parent and set_rate into the core omap clock code, rather than having these calls scattered throughout the OMAP1 and OMAP2 implementations. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-08[ARM] omap: provide a NULL clock operations structureRussell King2-45/+36

2009-01-29ARM: OMAP: Fix McBSP spin_lock deadlockStanley.Miao1-88/+10
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.
