      ARM: OMAP: HWMOD: Unify DSS resets for OMAPs · 13662dc5
      由 Tomi Valkeinen 提交于 
      This patch adds a custom DSS reset function used on OMAPs from OMAP2
forward.

The function doesn't actually do a reset, it only waits for the reset to
complete. The reason for this is that on OMAP4 there is no possibility
to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets
all the other DSS modules also, thus breaking the HWMOD model where
every DSS module is handled independently.

This fixes the problem with DSS reset on OMAP4, caused by the fact that
because there's no SW reset for dss_core on OMAP4, the HWMOD framework
doesn't try to reset dss_core and thus the DSS clocks were never enabled
at the same time. This causes causes the HWMOD reset to fail for
dss_dispc and dss_rfbi.

The common reset function will also allow us to fix another problem in
the future: before doing a reset we need to disable DSS outputs, which
are in some cases enabled by the bootloader, as otherwise DSS HW seems
to get more or less stuck, requiring a power reset to recover.

      omap: Set separate timer init functions to avoid cpu_is_omap tests · e74984e4
      由 Tony Lindgren 提交于 
      This is needed for the following patches so we can initialize the
rest of the hardware timers later on.

As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
rest of the hardware timers to happen with an arch_initcall.

      Now that omap_hwmod + omap_device is used for OMAP UART device and
driver code, we no longer need the UART physical addresses in
omap_globals.

Note that the #defines for the base addresses are still left in

      omap4: control: Add ctrl_pad_base to omap_globals · 0c349246
      由 Santosh Shilimkar 提交于 
      On omap4 control module is divided in four IP blocks.
- CTRL_MODULE_CORE			0x4a002000
- CTRL_MODULE_PAD_CORE		0x4a100000
- CTRL_MODULE_WKUP			0x4a30c000
- CTRL_MODULE_PAD_WKUP		0x4a31e000

Addressing all the modules with single base address is not possible
considering 16 bit offsets. The mux code manages the pad core and pad
wakeup related base address inside the mux framework. For other usage
only control core and control pad bases are necessary. So this patch
maps only needed pad control base address which is used by device drivers
and infrastructure code

The main control core base is still kept same in this patch to
keep git-bisect working. This will be fixed in the relevant patch
in this series.

Also, move these common PM init functions into a common_pm_init call

      OMAP3: PM: UART: disable clocks when idle and off-mode support · 4af4016c
      由 Kevin Hilman 提交于 
      This patch allows the UART clocks to be disabled when the OMAP UARTs
are inactive, thus permitting the chip to hit retention in idle.
After the expiration of an activity timer, each UART is allowed to
disable its clocks so the system can enter retention.  The activity
timer is (re)activated on any UART interrupt, UART wake event or any
IO pad wakeup.  The actual disable of the UART clocks is done in the
'prepare_idle' hook called from the OMAP idle loop.

While the activity timer is active, the smart-idle mode of the UART is
also disabled.  This is due to a "feature" of the UART module that
after a UART wakeup, the smart-idle mode may be entered before the
UART has communicated the interrupt, or upon TX, an idle mode may be
entered before the TX FIFOs are emptied.

Upon suspend, the 'prepare_suspend' hook cancels any pending activity
timers and allows the clocks to be disabled immediately.

In addition, upon disabling clocks the UART state is saved in case
of an off-mode transition while clocks are off.

Special thanks to Tero Kristo for the initial ideas and first versions
of UART idle support, and to Jouni Hogander for extra testing and
bugfixes.

Tested on OMAP3 (Beagle, RX51, SDP, EVM) and OMAP2 (n810)
