ARM: OMAP: Remove __omap_dm_timer_set_source function
The __omap_dm_timer_set_source() function is only used by the system timer
(clock-events and clock-source) code for OMAP2+ devices. Therefore, we can
remove this code from the dmtimer driver and move it to the system timer
code for OMAP2+ devices.
The current __omap_dm_timer_set_source() function calls clk_disable() before
calling clk_set_parent() and clk_enable() afterwards. We can avoid these calls
to clk_disable/enable by moving the calls to omap_hwmod_setup_one() and
omap_hwmod_enable() to after the call to clk_set_parent() in
omap_dm_timer_init_one().
The function omap_hwmod_setup_one() will enable the timers functional clock
and therefore increment the use-count of the functional clock to 1.
clk_set_parent() will fail if the use-count is not 0 when called. Hence, if
omap_hwmod_setup_one() is called before clk_set_parent(), we will need to call
clk_disable() before calling clk_set_parent() to decrement the use-count.
Hence, avoid these extra calls to disable and enable the functional clock by
moving the calls to omap_hwmod_setup_one() and omap_hwmod_enable() to after
clk_set_parent().
We can also remove the delay from the __omap_dm_timer_set_source() function
because enabling the clock will now be handled via the HWMOD framework by
calling omap_hwmod_setup_one(). Therefore, by moving the calls to
omap_hwmod_setup_one() and omap_hwmod_enable() to after the call to
clk_set_parent(), we can simply replace __omap_dm_timer_set_source() with
clk_set_parent().
It should be safe to move these hwmod calls to later in the
omap_dm_timer_init_one() because other calls to the hwmod layer that occur
before are just requesting resource information.
Testing includes boot testing on OMAP2420 H4, OMAP3430 SDP and OMAP4430 Blaze

ARM: OMAP3+: Implement timer workaround for errata i103 and i767
Errata Titles:
i103: Delay needed to read some GP timer, WD timer and sync timer
registers after wakeup (OMAP3/4)
i767: Delay needed to read some GP timer registers after wakeup (OMAP5)
Description (i103/i767):
If a General Purpose Timer (GPTimer) is in posted mode
(TSICR [2].POSTED=1), due to internal resynchronizations, values read in
TCRR, TCAR1 and TCAR2 registers right after the timer interface clock
(L4) goes from stopped to active may not return the expected values. The
most common event leading to this situation occurs upon wake up from
idle.
GPTimer non-posted synchronization mode is not impacted by this
limitation.
Workarounds:
1). Disable posted mode
2). Use static dependency between timer clock domain and MPUSS clock
domain
3). Use no-idle mode when the timer is active
Workarounds #2 and #3 are not pratical from a power standpoint and so
workaround #1 has been implemented. Disabling posted mode adds some CPU
overhead for configuring and reading the timers as the CPU has to wait
for accesses to be re-synchronised within the timer. However, disabling
posted mode guarantees correct operation.
Please note that it is safe to use posted mode for timers if the counter
(TCRR) and capture (TCARx) registers will never be read. An example of
this is the clock-event system timer. This is used by the kernel to
schedule events however, the timers counter is never read and capture
registers are not used. Given that the kernel configures this timer
often yet never reads the counter register it is safe to enable posted
mode in this case. Hence, for the timer used for kernel clock-events,
posted mode is enabled by overriding the errata for devices that are
impacted by this defect.
For drivers using the timers that do not read the counter or capture
registers and wish to use posted mode, can override the errata and
enable posted mode by making the following function calls.
__omap_dm_timer_override_errata(timer, OMAP_TIMER_ERRATA_I103_I767);
__omap_dm_timer_enable_posted(timer);
Both dmtimers and watchdogs are impacted by this defect this patch only
implements the workaround for the dmtimer. Currently the watchdog driver
does not read the counter register and so no workaround is necessary.
Posted mode will be disabled for all OMAP2+ devices (including AM33xx)
using a GP timer as a clock-source timer to guarantee correct operation.
This is not necessary for OMAP24xx devices but the default clock-source
timer for OMAP24xx devices is the 32k-sync timer and not the GP timer
and so should not have any impact. This should be re-visited for future
devices if this errata is fixed.
Confirmed with Vaibhav Hiremath that this bug also impacts AM33xx
devices.

ARM: OMAP2+: gpmc: generic timing calculation
Presently there are three peripherals that gets it timing
by runtime calculation. Those peripherals can work with
frequency scaling that affects gpmc clock. But timing
calculation for them are in different ways.
Here a generic runtime calculation method is proposed. Input
to this function were selected so that they represent timing
variables that are present in peripheral datasheets. Motive
behind this was to achieve DT bindings for the inputs as is.
Even though a few of the tusb6010 timings could not be made
directly related to timings normally found on peripherals,
expressions used were translated to those that could be
justified.
There are possibilities of improving the calculations, like
calculating timing for read & write operations in a more
similar way. Expressions derived here were tested for async
onenand on omap3evm (as vanilla Kernel does not have omap3evm
onenand support, local patch was used). Other peripherals,
tusb6010, smc91x calculations were validated by simulating
on omap3evm.
Regarding "we_on" for onenand async, it was found that even
for muxed address/data, it need not be greater than
"adv_wr_off", but rather could be derived from write setup
time for peripheral from start of access time, hence would
more be in line with peripheral timings. With this method
it was working fine. If it is required in some cases to
have "we_on" same as "wr_data_mux_bus" (i.e. greater than
"adv_wr_off"), another variable could be added to indicate
it. But such a requirement is not expected though.
It has been observed that "adv_rd_off" & "adv_wr_off" are
currently calculated by adding an offset over "oe_on" and
"we_on" respectively in the case of smc91x. But peripheral
datasheet does not specify so and so "adv_rd(wr)_off" has
been derived (to be specific, made ignorant of "oe_on" and
"we_on") observing datasheet rather than adding an offset.
Hence this generic routine is expected to work for smc91x
(91C96 RX51 board). This was verified on smsc911x (9220 on
OMAP3EVM) - a similar ethernet controller.
Timings are calculated in ps to prevent rounding errors and
converted to ns at final stage so that these values can be
directly fed to gpmc_cs_set_timings(). gpmc_cs_set_timings()
would be modified to take ps once all custom timing routines
are replaced by the generic routine, at the same time
generic timing routine would be modified to provide timings
in ps. struct gpmc_timings field types are upgraded from
u16 => u32 so that it can hold ps values.
Whole of this exercise is being done to achieve driver and
DT conversion. If timings could not be calculated in a
peripheral agnostic way, either gpmc driver would have to
be peripheral gnostic or a wrapper arrangement over gpmc
driver would be required.

ARM: OMAP: Add DT support for timer driver
In order to add device-tree support to the timer driver the following changes
were made ...
1. Allocate system timers (used for clock-events and clock-source) based upon
timer properties rather than using an hard-coded timer instance ID. To allow
this a new helper function called omap_dmtimer_find_by_property() has been
added for finding a timer with the particular properties in the device-tree
blob. Please note that this is an internal helper function for system timers
only to find a timer in the device-tree blob. This cannot be used by device
drivers, another API has been added for that (see below). Timers that are
allocated for system timers are dynamically disabled at boot time by adding
a status property with the value "disabled" to the timer's device-tree node.
Please note that when allocating system timers we now pass a timer ID and
timer property. The timer ID is only be used for allocating a timer when
booting without device-tree. Once device-tree migration is complete, all
the timer ID references will be removed.
2. System timer resources (memory and interrupts) are directly obtained from
the device-tree timer node when booting with device-tree, so that system
timers are no longer reliant upon the OMAP HWMOD framework to provide these
resources.
3. If DT blob is present, then let device-tree create the timer devices
dynamically.
4. When device-tree is present the "id" field in the platform_device structure
(pdev->id) is initialised to -1 and hence cannot be used to identify a timer
instance. Due to this the following changes were made ...
a). The API omap_dm_timer_request_specific() is not supported when using
device-tree, because it uses the device ID to request a specific timer.
This function will return an error if called when device-tree is present.
Users of this API should use omap_dm_timer_request_by_cap() instead.
b). When removing the DMTIMER driver, the timer "id" was used to identify the
timer instance. The remove function has been modified to use the device
name instead of the "id".
5. When device-tree is present the platform_data structure will be NULL and so
check for this.
6. The OMAP timer device tree binding has the following optional parameters ...
a). ti,timer-alwon --> Timer is in an always-on power domain
b). ti,timer-dsp --> Timer can generate an interrupt to the on-chip DSP
c). ti,timer-pwm --> Timer can generate a PWM output
d). ti,timer-secure --> Timer is reserved on a secure OMAP device

flags.

ARM: OMAP3: Add generic machine descriptor for boards with OMAP3 GP devices
OMAP3 devices may or may not have security features enabled. Security enabled
devices are known as high-secure (HS) and devices without security are known as
general purpose (GP).
Some OMAP3 boards, such as the OMAP3 beagle board, only use GP devices and for
GP devices there is a 12th timer available on-chip that can operate at 32kHz.
The clock for 12th timer is generated by an internal oscillator and is unique
this timer. Boards such as the beagle board use this timer as a 32kHz based
clock-events timer because early versions of the board had a hardware problem
preventing them from using other on-chip timers clocked by a external 32kHz
clock.
When booting with device-tree all OMAP3 devices use timer 1 by default for
the clock-events timer. Therefore, add a generic machine descriptor for boards
with OMAP3 GP devices so that they can use the 12th timer as the clock-events
timer instead of the default.

ARM: OMAP3: Dynamically disable secure timer nodes for secure devices
OMAP3 devices may or may not have security features enabled. Security enabled
devices are known as high-secure (HS) and devices without security are known as
general purpose (GP).
For OMAP3 devices there are 12 general purpose timers available. On secure
devices the 12th timer is reserved for secure usage and so cannot be used by
the kernel, where as for a GP device it is available. We can detect the OMAP
device type, secure or GP, at runtime via an on-chip register. Today, when not
using DT, we do not register the 12th timer as a linux device if the device is
secure.
When using device tree, device tree is going to register all the timer devices
it finds in the device tree blob. To prevent device tree from registering 12th
timer on a secure OMAP3 device we can add a status property to the timer
binding with the value "disabled" at boot time. Note that timer 12 on a OMAP3
device has a property "ti,timer-secure" to indicate that it will not be
available on a secure device and so for secure OMAP3 devices, we search for
timers with this property and then disable them. Using the prom_add_property()
function to dynamically add a property was a recommended approach suggested by
Rob Herring [1].
I have tested this on an OMAP3 GP device and faking it to pretend to be a
secure device to ensure that any timers marked with "ti,timer-secure" are not
registered on boot. I have also made sure that all timers are registered as
expected on a GP device by default.

i2c: mxs: remove broken PIOQUEUE support
This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
only PIOQUEUE was supported and it had issues, then DMA support was added
this cycle. The original intention was to keep PIOQUEUE since it has
less overhead what is nice for small transfers. However, runtime
switching between PIOQEUE and DMA depending on the transfer size never
worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
(polling at places where interrupts failed to work) and the
implementation also imposed a size limit for transfers, it is best to
remove the support, so users don't fall over its limitations. It also
makes the driver a lot cleaner and more robust. If somebody really wants
less overhead, plain PIO mode could still be implemented with the
addidtional advantage that this mode is also available on MX23, too.
