      OMAP2/3/4 PRCM: add module IDLEST wait code · 71348bca
      由 Paul Walmsley 提交于 
      After a hardware module's clocks are enabled, Linux must wait for it
to indicate readiness via its IDLEST bit before attempting to access
the device, otherwise register accesses to the device may trigger an
abort.  This has traditionally been implemented in the clock
framework, but this is the wrong place for it: the clock framework
doesn't know which module clocks must be enabled for a module to leave
idle; and if a module is not in smart-idle mode, it may never leave
idle at all.  This type of information is best stored in a
per-hardware module data structure (coming in a following patch),
rather than a per-clock data structure.  The new code will use these new
functions to handle waiting for modules to enable.

Once hardware module data is filled in for all of the on-chip devices,
the clock framework code to handle IDLEST waiting can be removed.

      ARM: OMAP2: Move sleep.S into sleep24xx.S · 1835f1d7
      由 Tony Lindgren 提交于 
      Some register offsets are different for 242x and 243x. This
will allow compiling sleep code for both chips into the same
kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the
omap24xx_cpu_suspend instead of loading the values since the only.

Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL
instead of the address as that's what omap24xx_cpu_suspend expects to
determine between DDR and SDR. This bug has not been noticed as
the boards seem to have DDR instead of SDR.

Note that some PM patches are still missing. The PM patches will
be added later on once the base files are in sync with linux-omap
tree.

      ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain code · d459bfe0
      由 Paul Walmsley 提交于 
      This patch creates an interface to the clockdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

The patch also adds clockdomain usecount tracking.  This is intended
to be called whenever the first clock in a clockdomain is enabled, or
when the last enabled clock in a clockdomain is disabled.  If the
clockdomain is in software-supervised mode, the code will force-wakeup
or force-sleep the clockdomain.  If the clockdomain is in
hardware-supervised mode, the first clock enable will add sleep and
wakeup dependencies on a user-selectable set of parent domains (usually
MPU & IVA2), and the disable will remove them.

Each clockdomain will be defined in later patches as static
structures.  The clockdomain structures are linked into a list at boot
by clkdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

      ARM: OMAP2: Powerdomain: Add base OMAP2/3 powerdomain code · ad67ef68
      由 Paul Walmsley 提交于 
      This patch creates an interface to the powerdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

Each powerdomain will be defined in later patches as static
structures.  Also defined are dependencies between powerdomains,
used for adding and removing PM_WKDEP and CM_SLEEPDEP bits.  The
powerdomain structures are linked into a list at boot by
pwrdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_POWERDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().
