commit c8d3578f8b ("pwm: pwm-qpnp: Ignore changing period setting if
it's not requested") had fixed an issue to avoid glitches seen in PWM
output when the PWM period is not changed and the duty cycle alone is
changed. However, that didn't fix the issue completely when the LPG
channel operation mode might be configured differently even when the
duty cycle is changed and the period is unchanged. This will lead to LPG
channel getting configured to operate in a wrong mode. Fix this by
enabling PWM output whenever there is a change in the mode for LPG
channel requested by the client.

It's not necessary to reprogram PWM period setting if only
changing PWM duty cycle.

commit 8d254a340efb12b40c4c1ff25a48a4f48f7bbd6b upstream.
When first implementing support for changing the output frequency, an
optimization was added to continue the PWM after changing the prescaler
without having to reprogram the ON and OFF registers for the duty cycle,
in case the duty cycle stayed the same. This was flawed, because we
compared the absolute value of the duty cycle in nanoseconds instead of
the ratio to the period.
Fix the problem by removing the shortcut.

Signed-off-by: Runmin Wang <runminw@codeaurora.org>
commit 0e1614ac84f1719d87bed577963bb8140d0c9ce8 upstream.
Make sure to drop the reference to the parent device taken by
class_find_device() after "unexporting" any children when deregistering
a PWM chip.

commit 0733424c9ba9f42242409d1ece780777272f7ea1 upstream.
Exported pwm channels aren't removed before the pwmchip and are
leaked. This results in invalid sysfs files. This fix removes
all exported pwm channels before chip removal.

commit ff01c944cfa939f3474c28d88223213494aedf0b upstream.
Commit d1cd214277 ("pwm: Set enable state properly on failed call to
enable") introduced a mutex that is needed to protect internal state of
PWM devices. Since that mutex is acquired in pwm_set_polarity() and in
pwm_enable() and might potentially block, all PWM devices effectively
become "might sleep".
It's rather pointless to keep the .can_sleep field around, but given
that there are external users let's postpone the removal for the next
release cycle.

[ Upstream commit 5a9fc9c666d5d759699cf5495bda85f1da0d747e ]
The change fixes a problem, if duty_ns is too small in comparison
to period_ns (as a valid corner case duty_ns is 0 ns), then due to
PWM_DUTY() macro applied on a value the result is overflowed over 8
bits, and instead of the highest bitfield duty cycle value 0xff the
invalid duty cycle bitfield value 0x00 is written.
For reference the LPC32xx spec defines PWMx_DUTY bitfield description
is this way and it seems to be correct:
[Low]/[High] = [PWM_DUTY]/[256-PWM_DUTY], where 0 < PWM_DUTY <= 255.
In addition according to my oscilloscope measurements LPC32xx PWM is
"tristate" in sense that it produces a wave with floating min/max
voltage levels for different duty cycle values, for corner cases:
PWM_DUTY == 0x01 => signal is in range from -1.05v to 0v
....
PWM_DUTY == 0x80 => signal is in range from -0.75v to +0.75v
....
PWM_DUTY == 0xff => signal is in range from 0v to +1.05v
PWM_DUTY == 0x00 => signal is around 0v, PWM is off
Due to this peculiarity on very long period ranges (less than 1KHz)
and odd pre-divider values PWM generated wave does not remind a
clock shape signal, but rather a heartbit shape signal with positive
and negative peaks, so I would recommend to use high-speed HCLK clock
as a PWM parent clock and avoid using RTC clock as a parent.
The change corrects PWM output in corner cases and prevents any
possible overflows in calculation of values for PWM_DUTY and
PWM_RELOADV bitfields, thus helper macro definitions may be removed.

[ Upstream commit ebe1fca35038df28b5c183e8486863e765364ec1 ]
LPC32xx SoC has two independent PWM controllers, they have different
clock parents, clock gates and even slightly different controls, and
each of these two PWM controllers has one output channel. Due to
almost similar controls arranged in a row it is incorrectly set that
there is one PWM controller with two channels, fix this problem, which
at the moment prevents separate configuration of different clock
parents and gates for both PWM controllers.
The change makes previous PWM device node description incompatible
with this update.

[ Upstream commit 816aec2325e620b6454474372a21f90a8740cb28 ]
A FTM PWM instance enables/disables three clocks: The bus clock, the
counter clock and the PWM clock. The bus clock gets enabled on
pwm_request, whereas the counter and PWM clocks will be enabled upon
pwm_enable.
The driver has three closesly related issues when enabling/disabling
clocks during suspend/resume:
- The three clocks are not treated differently in regards to the
individual PWM state enabled/requested. This can lead to clocks
getting disabled which have not been enabled in the first place
(a PWM channel which only has been requested going through
suspend/resume).
- When entering suspend, the current behavior relies on the
FTM_OUTMASK register: If a PWM output is unmasked, the driver
assumes the clocks are enabled. However, some PWM instances
have only 2 channels connected (e.g. Vybrid's FTM1). In that case,
the FTM_OUTMASK reads 0x3 if all channels are disabled, even if
the code wrote 0xff to it before. For those PWM instances, the
current approach to detect enabled PWM signals does not work.
- A third issue applies to the bus clock only, which can get enabled
multiple times (once for each PWM channel of a PWM chip). This is
fine, however when entering suspend mode, the clock only gets
disabled once.
This change introduces a different approach by relying on the enable
and prepared counters of the clock framework and using the frameworks
PWM signal states to address all three issues.
Clocks get disabled during suspend and back enabled on resume
regarding to the PWM channels individual state (requested/enabled).
Since we do not count the clock enables in the driver, this change no
longer clears the Status and Control registers Clock Source Selection
(FTM_SC[CLKS]). However, since we disable the selected clock anyway,
and we explicitly select the clock source on reenabling a PWM channel
this approach should not make a difference in practice.

Currently, glitch removal is enabled by default when the PWM
channel is configured. However, that adds delay to the PWM
output which is undesirable for longer PWM period. Disable the
glitch removal when PWM is configured and enable it after the
PWM is enabled.

commit c5857e3f94ab2719dfac649a146cb5dd6f21fcf3 upstream.
The change fixes potential oops while accessing iomem on invalid address
if devm_ioremap_resource() fails due to some reason.
The devm_ioremap_resource() function returns ERR_PTR() and never returns
NULL, which makes useless a following check for NULL.

Change to using upstream spmi bus architecture. All the spmi devices,
marked by spmi-dev-container, become platform devices.
spmi-slave-container devices become spmi_devices each representing
a slave. The read/write functions use regmap api's instead of calls to
spmi_ext_register_read/write() implemented by the spmi bus. This
regmap is instantiated per slave.
The spmi bus helper functions like spmi_get_irq get changed to their
platform bus equivalents.
Change Kconfig files include
* Remove dependence on OF_SPMI, MSM_QPNP_INT
* There were few places where an earlier commit
dcc2aedc80746acee589e4b47d3e6adf5d3ec253
missed adding dependence on SPMI along with MSM_SPMI.
Fix them.
* Add depends on ARCH_MSM. ARCH_MSM is used for internal builds.
Change the nodes in DTSI files to confirm to the modified drivers.
Update their binding docs to drop spmi-dev-container and
spmi-slave-container;
Finally update defconfig to use upstream SPMI.

For the npwm property the PWM sysfs interface already made use of the
DEVICE_ATTR_RO macro. This patch expands this to the other sysfs
properties so that the code base is concise and makes use of this
helpful macro.
This has the advantage of slightly reducing the code size, improving
readability and no longer using magic values for permissions.

When looking up a PWM using the lookup table, assume that all entries
will have been added already, so failure to find a match means that no
corresponding entry has been registered.
This fixes an issue where -EPROBE_DEFER would be returned if the PWM
lookup table is empty. After this fix, -EPROBE_DEFER is reserved for
situations where no provider has yet registered for a matching entry.

The pwm_enable() function didn't clear the enabled bit if a call to the
driver's ->enable() callback returned an error. The result was that the
state of the PWM core was wrong. Clearing the bit when enable returns
an error ensures the state is properly set.

by its users.
Get and use the slow clock as it is necessary for the timer counters.

This patch adds support for R-Car SoCs PWM Timer. The PWM timer of
R-Car H2 has 7 channels. So, we can use the channels if we describe
device tree nodes.

This platform driver has a OF device ID table but the OF module alias
information is not created so module autoloading won't work.
This patch adds the missing MODULE_DEVICE_TABLE() for OF to export that
information so modules have the correct aliases built-in and autoloading
works correctly.

This set of changes introduces the beginnings of a new API that's based
around the concept of states that can be atomically applied. Drivers go
to various lengths to implement something similar, which indicates that
the core should really be providing the necessary framework.
On top of that, there is a bit of cleanup as well as improved kerneldoc
and integration into the device-drivers DocBook.
Regarding drivers there is a new one for the NXP LPC18xx family of SoCs
and a couple of fixes for existing drivers (pca9685, Broadcom Kona and
Atmel HLCDC).

This commit adds support for NXP LPC18xx PWM/SCT.
NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State
Configurable Timer (SCT) which can be configured as a Pulse Width
Modulator. Other SoCs in that family may share the same hardware.
The PWM supports a total of 16 channels, but only 15 can be simultaneously
requested. There's only one period, global to all the channels, thus PWM
driver will refuse setting different values to it, unless there's only one
channel requested.

Previously, period_ns and duty_ns were only used to determine the
ratio of ON and OFF time, the default frequency of 200 Hz was never
changed.
The PCA9685 however is capable of changing the PWM output frequency,
which is expected when changing the period.
This patch configures the prescaler accordingly, using the formula
and notes provided in the PCA9685 datasheet.
Bounds checking for the minimum and maximum frequencies, last updated
in revision v.4 of said datasheet, is also added.
The prescaler is only touched if the period changed, because we have to
put the chip into sleep mode to unlock the prescale register.
If it is changed, the PWM output frequency changes for all outputs,
because there is one prescaler per chip. This is documented in the
PCA9685 datasheet and in the comments.
If the duty cycle is not changed at the same time as the period, then
we restart the PWM output using the duty cycle to period ratio from
before the period change.
When using LEDs for example, previously set brightness levels stay the
same when the frequency changes.

Problems:
- When duty_ns == period_ns, the full OFF bit was not cleared and the
PWM output of the PCA9685 stayed off.
- When duty_ns == period_ns and the catch-all channel was used, the
ALL_LED_OFF_L register was not cleared.
- The full ON bit was not cleared when setting the OFF time, therefore
the exact OFF time was ignored when setting a duty_ns < period_ns
Solution: Clear both OFF registers when setting full ON and clear the
full ON bit when changing the OFF registers.
