Kevin Hilman 28f3b5a073 gpio/omap: conslidate enable/disable of GPIO IRQs, remove ifdefs
Cleanup GPIO IRQ enable/disable handling by removing SoC-specific

Also split enable/disable IRQ into separate functions for better
readability and also facilitate potentially moving to generic irq_chip
in the future.

Kevin Hilman fa87931acb gpio/omap: consolidate direction, input, output, remove #ifdefs
Add register offset fields to GPIO platform_data for registers.

This patch adds registers that control direction, input and output
data.  Using these register offsets in the common driver allows
removal of #ifdefs and greatly improves readability.

Also create dedicated data out functions: one for banks with dedicated
set/clear registers, and another for banks with a single mask
register.

Tony Lindgren 741e3a89de omap: Use separate init_irq functions to avoid cpu_is_omap tests early
This allows us to remove cpu_is_omap calls from init_irq functions.
There should not be any need for cpu_is_omap calls as at this point.
During the timer init we only care about SoC generation, and not about
subrevisions.

The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call.

The V28_A domain in Nokia N900 that supplies VDD voltages to TLV320AIC34 and
TPA6130A2 should not be shutdown. This is because otherwise there will be
leak from VIO to VDD in TLV320AIC34 and this leak consumes more battery
current that is saved from keeping V28_A off. With this patch the battery
current consumption is approximately 1.5 mA lower.

Igor Grinberg e68273baf3 arm: omap2plus: fix ads7846 pendown gpio request
introduced by: 96974a24
(omap: consolidate touch screen initialization among different boards)

ads7846 driver can use either gpio_pendown or get_pendown_state()
callback. In case of gpio_pendown, it requests the provided gpio_pendown
thus resulting in double requesting that gpio:

ads7846 spi1.0: failed to request pendown GPIO57
ads7846: probe of spi1.0 failed with error -16

Fix this by restricting the gpio request to the case of
get_pendown_state() callback is used.

Jean Pihet 0490891819 OMAP3: cpuidle: change the power domains modes determination logic
The achievable power modes of the power domains in cpuidle
depends on the system wide 'enable_off_mode' knob in debugfs.
Upon changing enable_off_mode, do not change the C-states
'valid' field but instead dynamically restrict the power modes
when entering idle.

The C-states 'valid' field is just used to enable/disable some
C-states at init and shall not be changed later on.

Jean Pihet badc303a86 OMAP3: cpuidle: re-organize the C-states data
The current implementation defines an internal structure and a
C-states array. Using those structures is redundant to the
structs used by the cpuidle framework.

This patch provides a clean-up of the internal struct, removes the
internal C-states array, stores the data using the existing cpuidle
per C-state struct and registers the mach specific data to cpuidle
C-state driver_data (accessed using cpuidle_[gs]et_statedata).
Also removes unused macros, fields and code and compacts the repeating
code using an inline helper function.

The result is more compact and more readable code as well as
reduced data RAM usage.

Also retain C1 as the only always valid C-state and system safe state.

In commit 7538e3db6e (PM: add support
for device power domains) a better way for handling platform-specific
power hooks was introduced.

Rather than using the platform_bus dev_pm_ops overrides
(platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM
implementation over to using device power domains.

Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)

[rjw: Rebased on top of a previous change modifying the handling of
 power domains by the PM core so that power domain callbacks take
 precendence over subsystem-level PM callbacks.]

Blindly setting 1.2V in the initial structure may not even match the
default voltages stored in the voltage table which are supported for

ends up generating a warning on the first transition.

Further, since omap2_set_init_voltage is called as part of the pm
framework's initialization sequence to configure the voltage required
for the current OPP, the call does(and has to) setup the system
voltage(curr_volt as a result) using the right mechanisms appropriate
for the system at that point of time. This also overrides
initialization we are currently doing in voltage.c making it
redundant. So, remove the wrong and redundant initialization.

Eduardo Valentin a8ae645c01 OMAP3: PM: Do not rely on ROM code to restore CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL
As per OMAP3 erratum (i671), ROM code adds extra latencies while
restoring CM_AUTOIDLE_PLL register, if AUTO_PERIPH_DPLL is equal to 1.

This patch stores 0's in scratchpad content area corresponding to
AUTO_PERIPH_DPLL, to prevent ROM code to try to lock per DPLL, since
it won't respect proper programing scheme.

This register is then stored in prcm context. The saving and restore
is now done by kernel side.

Here follow the erratum description

DESCRIPTION

After OFF mode transition, among many restorations, the ROM Code restores the
CM_AUTOIDLE_PLL register, and after that, it tries to relock the PER DPLL.

In case the restoration data stored in scratchpad memory contains a field
CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL = 1, then the way the ROM Code restores and
locks the PER DPLL does not respect the PER DPLL programming scheme.

In that case, the DPLL might not lock. Meanwhile, when trying to lock the PER
DPLL, the ROM Code does not hang. Only extra latencies are introduced at
wake-up.

WORKAROUND

When saving the context-restore structure in scratchpad memory, in order to
respect the PER DPLL programming scheme, it is advised to store 0 in the
CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL field of the saved structure.

After wake-up, the application should store in CM_AUTOIDLE_PLL register the
right desired value.

Tomi Valkeinen 2df122f52f OMAP4: clock data: Change DSS clock aliases
DSS driver has used fck and ick clocks on OMAP2/3 to get DSS HW up and
running, and also to get the pixel clock's source clock rate from the
fck.

On OMAP4 the clock data is set up in a different way, as there's no ick,
dss_fck points to a fake clock which just affects DSS's MODULEMODE, and
dss_dss_clk if the DSS_FCK.

>From DSS driver's point of view the dss_fck sounds like an ick, and
dss_dss_clk is the fck. While this is not entirely correct from HW point
of view, especially for the ick, configuring the clock aliases that way
makes DSS "just work" with OMAP4's clock setup.

In the (hopefully near) future DSS driver will be reworked to use
pm_runtime support which should clean up the clock code.

Kalle Jokiniemi 10299e2e4e ARM: RX-51: Enable isp1704 power on/off
The isp1704 usb tranceiver is used for charging and can be
disabled when not in use. Provide the powering routine to
the driver via platform data.

Also changed the indent of ".name" variable in rx51_charger_device
definition to use tabs same way as the new ".dev" variable indent.
Put this in the same patch since the indent fix is only needed
when there are multiple members in the struct definition.

Loosely based on earlier patches from Heikki Krogerus in

Santosh Shilimkar 43b3e18982 ARM: 6860/1: OMAP4: Move the privately used SMP boot functions to OMAP specific header.
Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts.  They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.

Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h

The patch is outcome of the discussion in below thread:

Murthy, Raghuveer b295d6e593 OMAP4: PandaBoard: Adding DVI support
Adding DVI support to OMAP4 PandaBoard.

PandaBoard uses TFP410 DVI Framer chip
http://focus.ti.com/lit/ds/symlink/tfp410.pdf

The TFP410 gets its power enable and display data over GPIO lines muxed
in from OMAP4430. PandaBoard supports other LCD displays through
expansion
connectors, following board rework. This will disable the DVI interface.
However, the existing mux settings remain the same

PandaBoard additionally supports display over HDMI interface. It is
mutually exclusive to display over DVI. Hence the mux settings need to
be
configured seperately, as and when HDMI is enabled

Also, I2C3 bus used for reading EDID data from DVI Monitors is
registered here. Since the design is similar to BeagleBoard, the code
for the same is taken from the kernel.org commit e3333f48dd
(omap: Adding beagle i2c eeprom driver to read EDID)

Jean Pihet 5e7c58dc8d perf: add OMAP support for the new power events
The patch adds the new power management trace points for
the OMAP architecture.

The trace points are for:
- default idle handler. Since the cpuidle framework is
  instrumented in the generic way there is no need to
  add trace points in the OMAP specific cpuidle handler;
- SoC clocks changes (enable, disable, set_rate),
- power domain states: the desired target state and -if different-
  the actually hit state.

Because of the generic nature of the changes, OMAP3 and OMAP4 are supported.

Tested on OMAP3 with suspend/resume, cpuidle, basic DVFS.

archit taneja affe360d13 OMAP: DSS2: Have separate irq handlers for DISPC and DSI
Currently, the core DSS platform device requests for an irq line for OMAP2 and
OMAP3. Make DISPC and DSI platform devices request for a shared IRQ line.

On OMAP3, the logical OR of DSI and DISPC interrupt lines goes to the MPU. There
is a register DSS_IRQSTATUS which tells if the interrupt came from DISPC or DSI.

On OMAP2, there is no DSI, only DISPC interrupts goto the MPU. There is no
DSS_IRQSTATUS register.

Hence, it makes more sense to have separate irq handlers corresponding to the
DSS sub modules instead of having a common handler.

Since on OMAP3 the logical OR of the lines goes to MPU, the irq line is shared
among the IRQ handlers.

The hwmod irq info has been removed for DSS to DISPC and DSI for OMAP2 and OMAP3
hwmod databases. The Probes of DISPC and DSI now request for irq handlers.

Paul Walmsley c0718df4d6 OMAP2+: voltage: reorganize, split code from data
This is a first pass at reorganizing mach-omap2/voltage.c:

- Separate almost all of the data from the code of mach-omap2/voltage.c.
  The code remains in mach-omap2/voltage.c.  The data goes into one
  of several places, depending on what type of data it is:

  - Silicon process/validation data: mach-omap2/opp*_data.c
  - VC (Voltage Controller) data: mach-omap2/vc*_data.c
  - VP (Voltage Processor) data: mach-omap2/vp*_data.c
  - Voltage domain data: mach-omap2/voltagedomains*_data.c

  The ultimate goal is for all this data to be autogenerated, the same
  way we autogenerate the rest of our data.

- Separate VC and VP common data from VDD-specific VC and VP data.

- Separate common voltage.c code from SoC-specific code; reuse common code.

- Reorganize structures to avoid unnecessary memory loss due to unpacked
  fields.

There is much left to be done.  VC code and VP code should be separated out
into vc*.c and vp*.c files.  Many fields in the existing structures are
superfluous, and should be removed.  Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own.  Proper
voltage domain code should be created, as was done with the powerdomain
and clockdomains, and powerdomains should reference voltagedomains.

Paul Walmsley 570b54c7fa OMAP2+: clockdomain: add flag that will block autodeps from being added for a clockdomain
Add a new clockdomain flag, CLKDM_NO_AUTODEPS, which, when marked on a
clockdomain, will prevent "autodeps" from being associated with the
clockdomain.  ("Autodeps" are sleep dependencies and wakeup
dependencies from/to processor modules that are automatically added to
a clockdomain when it is in hardware-supervised idle mode.  They are
deprecated -- a relic from the old CDP trees -- but are still in use
for OMAP3.)

Also, prevent the hwmod code from adding or removing initiator
dependencies for clockdomains with this flag set.

This patch should allow others to test which clockdomains actually
still need autodeps.

Thanks to Kevin Hilman <khilman@ti.com> for noting that the original
version should also modify the hwmod code.

Paul Walmsley c39bee8ac4 OMAP2/3: VENC hwmod: add OCPIF_SWSUP_IDLE flag to interface
According to the hwmod interface data, the DSS submodule "VENC" uses a
clock, "dss_54m_fck"/"dss_tv_fck", which the PRCM cannot autoidle.  By
default, the hwmod code assumes that interface clocks can be autoidled
by the PRCM.  When the interface clock can't be autoidled by the PRCM,
those interfaces must be marked with the OCPIF_SWSUP_IDLE flag.
Otherwise, the "interface clock" will always have a non-zero use
count, and the device won't enter idle.  This problem was observed on
N8x0.

Fix the immediate problem by marking the VENC interface with the
OCPIF_SWSUP_IDLE flag.  But it's not clear that
"dss_54m_fck"/"dss_tv_fck" is really the correct interface clock for
VENC.  It may be that the VENC interface should use a
hardware-autoidling interface clock.  This is the situation on OMAP4,
which uses "l3_div_ck" as the VENC interface clock, which can be
autoidled by the PRCM.  Clarification from TI is needed.

Problem found and patch tested on N8x0 by Tony Lindgren

After commit 81b34fbecb ("OMAP2 clock:

possible to remove dsp_irate_ick from the OMAP2420 and OMAP2430 clock

Paul Walmsley 19c1c0ce9d OMAP2xxx: clock: fix interface clocks and clockdomains for modules in the WKUP domain
The parent of the interface clocks for GPTIMER1, MPU_WDT,
SYNCTIMER_32K, SCM, WDT1, and the ICR (2430 only) were all listed as
being l4_ck.  This isn't accurate; these modules exist inside the WKUP
domain, and the interface clock to these modules runs at the SYS_CLK
rate rather than the CORE L4 rate.

So, create a new clock "wu_l4_ick", similar to the OMAP3
"wkup_l4_ick", that serves as the parent for these clocks.

Also, these clocks were listed as existing inside core_l4_clkdm;
wkup_clkdm is probably more accurate.

Paul Walmsley 694606c4ef OMAP2+: powerdomain: add pwrdm_can_ever_lose_context()
Some drivers wish to know whether the device that they control can
ever lose context, for example, when the device's enclosing
powerdomain loses power.  They can use this information to determine
whether it is necessary to save and restore device context, or whether
it can be skipped.  Implement the powerdomain portion of this by
adding the function pwrdm_can_ever_lose_context().  This is not for
use directly from driver code, but instead is intended to be called
from driver-subarch integration code (i.e., arch/arm/*omap* code).

Currently, the result from this function should be passed into the
driver code via struct platform_data, but at some point this should
be part of some common or OMAP-specific device code.

While here, update file copyrights.

Anand Gadiyar 09173b589d arm: omap4: 4430sdp: drop ehci support
Most revisions of the OMAP4 Blaze/SDP platform do not have
the EHCI signals routed by default. The pads are routed
for the alternate HSI functionality instead, and explicit
board modifications are needed to route the signals to
the USB PHY on the board.

Also, turning on the PHY connected to the EHCI port causes
a board reboot during bootup due to an unintended short
on the rails - this affects many initial revisions of the
board, and needs a minor board mod to fix (or as a
workaround, one should not attempt to power on the
USB PHY).

Given that these boards need explicit board mods to even
get EHCI working (separate from the accidental short above),
we should not attempt to enable EHCI by default.

So drop the EHCI support from the board files for the
Blaze/SDP platforms.

Kishore Kadiyala 6ab8946f67 OMAP: hwmod data: Add dev_attr and use in the host driver
Add a device attribute to hwmod data of omap2430, omap3, omap4.
Currently the device attribute holds information regarding dual volt MMC card
support by the controller which will be later passed to the host driver via
platform data.

Anand Gadiyar e08016d0f4 omap: mmc: split out init for 2420
The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter
are identical. The one on the OMAP2420 is closer to that
on OMAP1 chips.

Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
potentially invasive. To reduce the risk, separate out the
2420 controller registration from the common init function
and update its only user. Also seperating out mux settings
for OMAP2420.

Keshava Munegowda 53689ac1b6 arm: omap: usb: clock entries for omap3 and omap4
The devices of clocks are set to usbhs, so that
only usbhs common driver can invoke these clocks.
The dummy per port clocks are added to omap3
clock data base. This helps to invoke common
clock get APIs for omap3 and omap4.
