* OMAP2420: clock: use autoidle clkops for all autoidle-controllable interface ↵Paul Walmsley2011-03-081-0/+2
| | | | | | | | | | | | | | clocks Mark each interface clock with a corresponding CM_AUTOIDLE bit with a clkops that has the allow_idle/deny_idle function pointers populated. This allows the OMAP clock framework to enable and disable autoidle for these clocks.

* OMAP2420: clock: add sdrc_ickPaul Walmsley2011-03-081-0/+1

* OMAP2/3: clockdomain: remove unneeded .clkstctrl_reg, remove some direct CM ↵Paul Walmsley2010-12-221-0/+5
| | | | | | | | | | | | | | | | | | | | register accesses Reverse some of the effects of commit 84c0c39aec31a09571fc08a752a2f4da0fe9fcf2 ("ARM: OMAP4: PM: Make OMAP3 Clock-domain framework compatible for OMAP4"). On OMAP2/3, the CM_CLKSTCTRL register is at a constant offset from the powerdomain's CM instance. Also, remove some of the direct CM register access from the clockdomain code, moving it to the OMAP2/3 CM code instead. The intention here is to simplify the clockdomain code. (The long-term goal is to move all direct CM register access across the OMAP core code to the appropriate cm*.c file.)

* OMAP2/3: PRCM: split OMAP2/3-specific PRCM code into OMAP2/3-specific filesPaul Walmsley2010-12-221-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for adding OMAP4-specific PRCM accessor/mutator functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was OMAP2xxx/3xxx-specific. This process also requires the #includes in each of these files to be changed to reference the new file name. As part of doing so, add some comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use "sideways includes", to indicate that these users of the PRM/CM includes should not be doing so.

* OMAP2xxx: hwmod: add I2C hwmods for OMAP2420, 2430Paul Walmsley2010-11-091-0/+4
| | | | | | | | | | | | | Add hwmod structures for I2C controllers on OMAP2420/2430. NOTE: I2C module on OMAP2420 has 16bit registers and causes imprecise aborts if 32bits are read/written to it. Use the HWMOD_16BIT_REG flag to notify the hmwod framework of this hard requirement so that __raw_writew/readw is used to read /write the mdoule registers.

* OMAP2 PRCM: convert OMAP2 PRCM macros to the _SHIFT/_MASK suffixesPaul Walmsley2010-05-201-118/+118
| | | | | | | | | | | Fix all of the remaining OMAP2 PRCM register shift/bitmask macros that did not use the _SHIFT/_MASK suffixes to use them. This makes the use of these macros consistent. It is intended to reduce error, as code can be inspected visually by reviewers to ensure that bitshifts and bitmasks are used in the appropriate places.

* [ARM] OMAP2 PRCM: clean up CM_IDLEST bitsPaul Walmsley2009-02-081-27/+53
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes a few OMAP2xxx CM_IDLEST bits that were incorrectly marked as being OMAP2xxx-wide, when they were actually 2420-specific. Also, originally when the PRCM register macros were defined, bit shift macros used a "_SHIFT" suffix, and mask macros used none. This became a source of bugs and confusion, as the mask macros were mistakenly used for shift values. Gradually, the mask macros have been updated, piece by piece, to add a "_MASK" suffix on the end to clarify. This patch applies this change to the CM_IDLEST_* register bits. The patch also adds a few bits that were missing, mostly from the 3430ES1 to ES2 revisions. linux-omap source commits are d18eff5b5fa15e170794397a6a94486d1f774f77, e1f1a5cc24615fb790cc763c96d1c5cfe6296f5b, and part of 9fe6b6cf8d9e0cbb429fd64553a4b3160a9e99e1 Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
