The CLOCK_IN_OMAP4430 clock flag is not currently needed in the OMAP4
ES1 clock tree, and platform discrimination via clock flags is
deprecated in favor of the clkdev mechanism, so, drop it. (The OMAP4
clock tree autogeneration script has been updated accordingly.)

includes, documentation
The maximum DPLL multiplier (M) values for OMAP2xxx and OMAP3xxx are
one increment higher than they should be. See for example the
OMAP242x TRM Rev X Section 5.10.6 "Clock Generator Registers" and the
OMAP36xx TRM Rev C Table 3-202 "CM_CLKSEL1_PLL". Programming a 0 into
the DPLL's M register bitfield is valid for OMAP2/3 and indicates that
the DPLL should enter MN-bypass mode. Also, increase the minimum
multiplier (M) value for the DPLL rate rounding code from 1 to 2, to
ensure that it does not inadvertently put the DPLL into bypass.
Note that the register documentation in the OMAP2xxx and OMAP3xxx TRMs
does not make clear that the actual DPLL divider value (the "N") is
the content of the appropriate register bitfield for the N value,
_plus one_. (In other words, an N register bitfield of 0 indicates a
DPLL divider value of 1.) This is only clearly documented in the
OMAP4430 TRM, in, for example, OMAP4430 TRM Rev A Table 3-1167
"CM_CLKSEL_DPLL_USB".
While here, update copyrights, add kerneldoc for struct dpll_data,
drop the unused struct dpll_data.max_tolerance field, remove some
unnecessary #includes in DPLL-related code, and replace the #include
of <linux/module.h> with <linux/list.h>, which is what was really
needed. The OMAP4 clock autogenerator script has been updated
accordingly.

In 3630, DPLL4M2 output can be 96MHz or 192MHz (for SGX to run at
192). This patch has changes to support this feature. 96MHz clock is
generated by dividing 192Mhz clock by 2 using CM_CLKSEL_CORE register.
SGX can select Core Clock, 192MHz clock or CM_96M_FCLK as it's
functional clock. In summary changes done are:
1. Added a feature called omap3_has_192mhz_clk and enabled for 3630
2. Added a new clock node called omap_192m_alwon_ck
3. Made omap_96m_alwon_fck to derive its clock from omap_192m_alwon_ck

This patch implements a workaround for the DPLL HS divider limitation
in OMAP3630 as given by Errata ID: i556.
Errata:
When PWRDN bit is set, it resets the internal HSDIVIDER divide-by value (Mx).
The reset value gets loaded instead of the previous value.
The following HSDIVIDERs exhibit above behavior:
. DPLL4 : M6 / M5 / M4 / M3 / M2 (CM_CLKEN_PLL[31:26] register bits)
. DPLL3 : M3 (CM_CLKEN_PLL[12] register bit).
Work Around:
It is mandatory to apply the following sequence to ensure the write
value will
be loaded in DPLL HSDIVIDER FSM:
The global sequence when using PWRDN bit is the following:
. Disable Mx HSDIVIDER clock output related functional clock enable bits
(in CM_FCLKEN_xxx / CM_ICLKEN_xxx)
. Enable PWRDN bit of HSDIVIDER
. Disable PWRDN bit of HSDIVIDER
. Read current HSDIVIDER register value
. Write different value in HSDIVIDER register
. Write expected value in HSDIVIDER register
. Enable Mx HSDIVIDER clock output related functional clocks
(CM_FCLKEN_xxx / CM_ICLKEN_xxx)

This patch adds support in omap device layer to register devices
as early platform devices. Certain devices needed during system boot up
like timers, gpio etc can be registered as early devices. This will
allow for them to be probed very early on during system boot up.
This patch adds a parameter is_early_device in omap_device_build.
Depending on this parameter a call to early_platform_add_devices
or platform_register_device is made.

register bits.
In OMAP3 Some modules like Smartreflex do not have the regular sysconfig
register.Instead clockactivity bits are part of another register at a
different bit position than the usual bit positions 8 and 9.
In OMAP4, a new scheme is available due to the new protocol
between the PRCM and the IPs. Depending of the scheme, the SYSCONFIG
bitfields position will be different.
The IP_REVISION register should be at offset 0x00.
It should contain a SCHEME field. From this we can determine whether
the IP follows legacy scheme or the new scheme.
31:30 SCHEME Used to distinguish between old scheme and current.
Read 0x0: Legacy protocol.
Read 0x1: New PRCM protocol defined for new OMAP4 IPs
For legacy IP
13:12 MIDLEMODE
11:8 CLOCKACTIVITY
6 EMUSOFT
5 EMUFREE
4:3 SIDLEMODE
2 ENAWAKEUP
1 SOFTRESET
0 AUTOIDLE
For new OMAP4 IP's, the bit position in SYSCONFIG is (for simple target):
5:4 STANDBYMODE (Ex MIDLEMODE)
3:2 IDLEMODE (Ex SIDLEMODE)
1 FREEEMU (Ex EMUFREE)
0 SOFTRESET
Unfortunately In OMAP4 also some IPs will not follow any of these
two schemes. This is the case at least for McASP, SmartReflex
and some security IPs.
This patch introduces a new field sysc_fields in omap_hwmod_sysconfig which
can be used by the hwmod structures to specify the offsets for the
sysconfig register of the IP.Also two static structures
omap_hwmod_sysc_type1 and omap_hwmod_sysc_type2 are defined
which can be used directly to populate the sysc_fields if the IP follows
legacy or new OMAP4 scheme. If the IP follows none of these two schemes
a new omap_hwmod_sysc_fields structure has to be defined and
passed as part of omap_hwmod_sysconfig.

Current implementation defines clock idle state indicators based on the
cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide
manner. This patch extends the find_idlest() function in clkops to pass
back the idle state indicator for that clock, thus allowing idle state
indicators to be defined on a per clock basis if required.
This is specifically needed on AM35xx devices as the new IPSS clocks
indicates the idle status (0 is idle, 1 is ready) in a way just
opposite to how its handled in OMAP3 (0 is ready, 1 is idle).

retention.
This patch adds counters to keep track of whether the powerdomain
logic or software controllable memory banks are turned off when
the power domain enters retention. During power domain retention
if logic gets turned off, the scenario is known as Open Switch Retention.
Also during retention s/w controllable memory banks of a power
domain can be chosen to be kept in retention or off.
This patch adds one counter per powerdomain to track the power domain
logic state during retention. Number of memory bank state counters
added depends on the number of software controllable memory banks
of the powerdomain. To view these counters do

The omap_device struct contains a 'struct platform_device'. Normally,
converting a platform_device pointer to an omap_device pointer
consists of simply doing a container_of(), as is done currently by the
to_omap_device() macro.
However, if this is attempted when using platform_device that has not
been created as part of the omap_device creation, the container_of()
will point to a memory location before the platform_device pointer
which will contain random data.
Therefore, we need a way to detect valid omap_device pointers. This
patch solves this by using the simple magic number approach.

EMMC can have two voltage supplies, Vcc and VccQ
which are implemented in the code as consumer
supplies vmmc and vmmc_aux.
If the regulator that supplies vmmc_aux is shared
with other consumers, then sending it to sleep
will disrupt those consumers. However, the
TWL4030-family regulators may have OFF remapped
to SLEEP, in which case 'regulator_disable()'
will put the regulator to sleep only when all
consumers are disabled - which is the desired
behaviour.

This patch moves the setup code for GPIO's and Voltage
Regulators from the board file mmc-twl4030.c to the
driver omap_hsmmc.c. PBIAS and other system control
configuration remains in the board file.
Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined. That makes the
board initialisation now entirely independent of its original
twl4030 roots.
Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code. It also
permits the MMC core to be compiled as a module, because the
board code no longer calls MMC core functions.

This patch adds 'board-sdp-flash.c', which could be utilized

This file does initialization for all three flash devices present

dynamically using switch setting information (S8: 1-4).
This also expects partition information from core board files (for
ex: board-3430sdp.c). Which allows to choose different default
partitions for different boards.
A new structure is created for this purpose: 'flash_partitions'
in 'mach/board-sdp.h'. This has two members:
1. struct mtd_partition *parts
2. int nr_parts
A board file is expected to fill this structure and pass it to

be passed in below sequence in array:

Change the way McBSP registers are updated: use cached values instead of
relying upon those read back from the device.
With this patch, I have finally managed to get rid of all random
playback/recording hangups on my OMAP1510 based Amstrad Delta hardware. Before
that, values read back from McBSP registers to be used for updating them
happened to be errornous.
From the hardware side, the issue appeared to be caused by a relatively high
power requirements of an external USB adapter connected to the board's printer
dedicated USB port.
I think there is one important point that makes this patch worth of applying,
apart from my hardware quality. With the current code, if it ever happens to
any machine, no matter if OMAP1510 or newer, to read incorrect value from a
McBSP register, this wrong value will get written back without any checking.
That can lead to hardware damage if, for example, an input pin is turned into
output as a result.
Applies on top of patch 3 from this series:
