2012-04-19ARM: OMAP2+: clockdomains: make {prm,cm}_clkdm commonPaul Walmsley
The PRM and CM implicit clockdomains will soon be used by OMAP44xx. So, make them common to OMAP2+ and modify the OMAP4 clockdomains code so use of these clockdomains doesn't crash the system. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Rajendra Nayak <rnayak@ti.com>
2011-09-14OMAP: clockdomain code/data: remove omap_chip bitmask from struct clockdomainPaul Walmsley
At Tony's request, remove the omap_chip bitmasks from the clockdomain and clockdomain dependency definitions. Instead, initialize clockdomains based on one or more lists that are applicable to a particular SoC family, variant, and silicon revision. Tony Lindgren <tony@atomide.com> found a bug in a previous version of this patch - thanks Tony. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Tony Lindgren <tony@atomide.com>
2011-07-10OMAP2+: clockdomain: Add per clkdm lock to prevent concurrent state programmingRajendra Nayak
Since the clkdm state programming is now done from within the hwmod framework (which uses a per-hwmod lock) instead of the being done from the clock framework (which used a global lock), there is now a need to have per-clkdm locking to prevent races between different hwmods/modules belonging to the same clock domain concurrently programming the clkdm state.

2011-02-25OMAP4: clockdomain: Add wkup/sleep dependency supportRajendra Nayak
Add OMAP4 platform specific implementation to support clkdm wkup and sleep dependencies a.k.a static dependencies. Signed-off-by: Rajendra Nayak <rnayak@ti.com> [paul@pwsan.com: removed comment about PRM; zero-prefixed STATICDEP register offset; fixed loop termination condition in omap4_clkdm_clear_all_wkup_sleep_deps(); thanks to Kevin Hilman for finding and helping fix this bug] Cc: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2011-02-25OMAP: clockdomain: Arch specific funcs for clkdm_clk_enable/disableRajendra Nayak
Define the following architecture specific funtions for omap2/3/4 .clkdm_clk_enable .clkdm_clk_disable Convert the platform-independent framework to call these functions. Also rename the api's by removing the omap2_ preamble. Hence call omap2_clkdm_k_enable as clkdm_clk_enable and omap2_clkdm_clk_disable as clkdm_clk_disable.a Remove unused functions (_enable/_disable_hwsup) and unsed headers from clockdomain.c file.

2011-02-25OMAP: clockdomain: Arch specific funcs for hwsup control of clkdmRajendra Nayak
Define the following architecture specific funtions for omap2/3/4 .clkdm_allow_idle .clkdm_deny_idle Convert the platform-independent framework to call these functions. Also rename the api's by removing the omap2_ preamble. Hence call omap2_clkdm_allow_idle as clkdm_allow_idle and omap2_clkdm_deny_idle as clkdm_deny_idle. Make the _clkdm_add_autodeps and _clkdm_del_autodeps as non-static so they can be accessed from OMAP2/3 platform specific code.

2011-02-25OMAP: clockdomain: Arch specific funcs for sleep/wakeup of clkdmRajendra Nayak
Define the following architecture specific funtions for omap2/3/4 .clkdm_sleep .clkdm_wakeup Convert the platform-independent framework to call these functions. Also rename the api's by removing the omap2_ preamble. Hence call omap2_clkdm_wakeup as clkdm_wakeup and omap2_clkdm_sleep as clkdm_sleep. Signed-off-by: Rajendra Nayak <rnayak@ti.com> [paul@pwsan.com: fixed omap3_clkdm_clear_all_sleepdeps() and omap2_clkdm_clear_all_wkdeps() to test against the correct loop termination condition; thanks to Kevin Hilman for finding and helping fix] Cc: Kevin Hilman <khilman@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
