phy: rockchip-inno-usb2: don't power on otg phy in ls irq handler

The commit c590056b6ab8 ("phy: rockchip-inno-usb2: usb remote
wakeup support") power on otg phy in linestate irq handler,
this will cause usb peripheral fail to connect to PC in the
following case:
1. enable otg linestate irq
2. set system enter deep sleep
3. wakeup system by power key
4. connect usb peripheral to PC, pull up D+ to ~3V, trigger
   linestate irq and power on otg phy.
5. usb peripheral do BC1.2 detect, but PC try to enumerate
   the usb peripheral at the same time and fail at last.

Actually the usb controller drivers (e.g. dwc3 driver)
and otg_sm_work can manage the otg phy power consumption, so
it doesn't need to power on otg phy in linestate irq handler.

usb: dwc_otg_310: pcd: fix isoc in ep transfer issue

When test usb gadget uvc function, we find a isoc in
ep transfer bug that will cause uvc data transfer fail.
The error case is:

1. The current EP request is done, call complete_ep()
to completes the request, and then call start_next_request()
to check the EP request queue, in this error case, the
queue is empty, so it doesn't start next request, just
set ep frame_num to 0xFFFFFFFF.

2. NAK Interrutp is triggered, check isoc ep frame_num
is 0xFFFFFFFF, then reset the frame_num to 0, and then
call start_next_request() to check the EP request queue,
in this error case, the queue is still empty, so set ep
frame_num to 0xFFFFFFFF again.

But afer the above operation, the current code will
modify the ep frame_num in NAK Interrutp handler by
add ep bInterval to frame_num, this cause frame_num
change again, but not keep in 0xFFFFFFFF, so the next
NAK Interrutp handler doesn't start next request any
more.

This patch reset the frame_num to the current frame
number got from DSTS SOFFN register if detect the
frame_num is 0xFFFFFFFF in NAK Interrutp handler.
And modify the frame_num in NAK Interrutp handler
only when the frame_num is not 0xFFFFFFFF.

TEST=Set usb gadget as webcam, use Ubuntu Guvcview
to preview the webcam, observe the preview screen
and the error log "There are no more ISOC requests".

should disable pwm clock for saving power consume.

UPSTREAM: pwm: cros-ec: Add __packed to prevent padding

While the particular usage in question is likely safe (struct
cros_ec_command is 32-bit aligned, followed by <= 32-bit fields), it's
been suggested this is not a great pattern to follow for the general
case -- for example, if we follow a 'struct cros_ec_command' (which is
32-bit- but not 64-bit-aligned) with a struct that starts with a 64-bit
type (e.g., u64), the compiler may add padding.

Let's add __packed, to inform the compiler of our true intention -- to
have no padding between these struct elements -- and to future proof for
any refactorings that might occur.

UPSTREAM: pwm: Add ChromeOS EC PWM driver

Use the new ChromeOS EC EC_CMD_PWM_{GET,SET}_DUTY commands to control
one or more PWMs attached to the Embedded Controller. Because the EC
allows us to modify the duty cycle (as a percentage, where U16_MAX is
100%) but not the period, we assign the period a fixed value of
EC_PWM_MAX_DUTY and reject all attempts to change it.

This driver supports only device tree at the moment, because that
provides a very flexible way of describing the relationship between PWMs
and their consumer devices (e.g., backlight). On a non-DT system, we'll
probably want to use the non-GENERIC addressing (i.e., we'll need to
make special device instances that will use EC_PWM_TYPE_KB_LIGHT or
EC_PWM_TYPE_DISPLAY_LIGHT), as well as the relatively inflexible
pwm_lookup infrastructure for matching devices. Defer that work for now.

UPSTREAM: dt-bindings: pwm: Add binding for ChromeOS EC PWM

The ChromeOS Embedded Controller can support controlling its attached

on a per-board basis, but we can autodetect this by checking the error
codes, so we don't need an extra property for this. And because the EC
only allows specifying the duty cycle and not the period, we don't

UPSTREAM: regulator: pwm: Support extra continuous mode cases

The continuous mode allows one to declare a PWM regulator without having
to declare the voltage <-> dutycycle association table. It works fine as
long as your voltage(dutycycle) function is linear, but also has the
following constraints:

- dutycycle for min_uV = 0%
- dutycycle for max_uV = 100%
- dutycycle for min_uV < dutycycle for max_uV

While the linearity constraint is acceptable for now, we sometimes need to
restrict of the PWM range (to limit the maximum/minimum voltage for
example) or have a min_uV_dutycycle > max_uV_dutycycle (this could be
tweaked with PWM polarity, but not all PWMs support inverted polarity).

Add the pwm-dutycycle-range and pwm-dutycycle-unit DT properties to define
such constraints. If those properties are not defined, the PWM regulator
use the default pwm-dutycycle-range = <0 100> and
pwm-dutycycle-unit = <100> values (existing behavior).

The current implementation always round down the duty and period values,
while it would be better to round them to the closest integer.

These changes are needed in preparation of atomic update support to
prevent a period/duty cycle drift when executing several times the
'pwm_get_state() / modify / pwm_apply_state()' sequence.

Say you have an expected period of 3.333 us and a clk rate of
112.666667 MHz -- the clock frequency doesn't divide evenly, so the
period (stashed in nanoseconds) shrinks when we convert to the register
value and back, as follows:

  pwm_apply_state(): register = period * 112666667 / 1000000000;
  pwm_get_state(): period = register * 1000000000 / 112666667;

or in other words:

  period = period * 112666667 / 1000000000 * 1000000000 / 112666667;

which yields a sequence like:

  3333 -> 3328
  3328 -> 3319
  3319 -> 3310
  3310 -> 3301
  3301 -> 3292
  3292 -> ... (etc) ...

With this patch, we'd see instead:

  period = div_round_closest(period * 112666667, 1000000000) *
                   1000000000 / 112666667;

which yields a stable sequence:

  3333 -> 3337
  3337 -> 3337
  3337 -> ... (etc) ...
