and use same clock rate, it's hardware limitation.

phy: rockchip-inno-usb2: support to force otg mode

This patch creates an usb2 phy attribute group and
provides an attribute "otg_mode" for otg port to
force otg mode independently of the voltage of otg
id pin.

In order to implement the force mode function, we can
select otg plug indicator output (AKA iddig) from GRF,
and set GRF USB otg plug indicator to "0" or "1" to
control iddig status.

We only support rk322x/rk3328 to force otg mode for
the time being.

And we need to disable usb auto suspend function if
we want to force otg mode. Add 'usbcore.autosuspend=-1'
in cmdline to disable usb auto suspend.

Usage:
[1] Force host mode
    echo host > /sys/devices/platform/<u2phy dev name>/mode

[2] Force peripheral mode
    echo peripheral > /sys/devices/platform/<u2phy dev name>/mode

[3] Force otg mode
    echo otg > /sys/devices/platform/<u2phy dev name>/mode

Legacy Usage:
[1] Force host mode
    echo 1 > /sys/devices/platform/<u2phy dev name>/mode

[2] Force peripheral mode
    echo 2 > /sys/devices/platform/<u2phy dev name>/mode

[3] Force otg mode
    echo 0 > /sys/devices/platform/<u2phy dev name>/mode

phy: rockchip-inno-usb2: fix some race conditions

There are some race conditions related to phy power on/off
and otg charger detection work, otg sm work. I can find at
least three race conditions at present.

Race condition[1]:
The first race condition involving phy power on/off which
may be caused by the following case.

Test on rk3399 evaluation board Type-C0, connect to PC usb
port with Type-C cable, then phy power on/off operation may
be done twice because of race condition between phy driver
and usb controller driver.

CPU 0:
- rockchip_usb2phy_bvalid_irq()
 - rockchip_usb2phy_otg_sm_work()
  - detect connect to PC usb, do phy power on
   - rockchip_usb2phy_power_on()

CPU 1:
- dwc3 driver do runtime resume process
 - dwc3_runtime_resume()
  - dwc3_core_init()
   - phy_power_on()
    - rockchip_usb2phy_power_on()

Although we use a suspended flag in rockchip_usb2phy_power_on()
to avoid doing the same things twice, but it's not enough to
prevent race condition if phy driver and usb controller driver
access the rockchip_usb2phy_power_on() at the same time. This
race condition may cause clk management unbalanced.

Race condition[2]:
The second race condition related to phy power on/off and otg
charger detection work. We need to keep the usb phy staying in
suspend mode when do usb charger detection. But now it don't
have any protection to prevent the other threads to operate phy
during charger detection.

The problem can also be easily reproduced on rk3399 evaluation
board Type-C0 when connect to PC usb port with Type-C cable.

CPU 0:
- rockchip_chg_detect_work()
 - power off phy and start to do charge detection work

CPU 1:
- dwc3 driver do runtime resume process
 - dwc3_runtime_resume()
  - dwc3_core_init()
   - phy_power_on()
    - power on phy again

This race condition may cause charger detection and later usb
enumeration abnormally.

Race condition[3]:
The third race condition involving otg sm work. The otg sm
work can be interrupted by bvalid irq, and the bvalid irq
handler rockchip_usb2phy_bvalid_irq() will do otg sm work,
which may cause unknown error.

This patch uses mutex lock to protect the phy operations,
otg charger detection work and otg sm work.

The shared uart-pll is on boot a child of the apll that can get changed

OP-TEE: fix warning when LPAE is activated on ARM

When LPAE is activated, the dma_addr_t type is u64,
but pointer is still 32bit on arm32 platform.
1. %pad is used to print dma_addr_t type in log.
2. The member paddr(dma_addr_t type) in struct shm is cast
to unsigned long when it needs to be cast to a pointer. The cast
is fine as the value of paddr in struct shm is always less than 4G.

fiq debugger: rockchip: fix crash because of invalid sp_el0

(1) use cpu id from bl31 delivers;
(2) sp_el0 should point to kernel address in EL1 mode.

On ARM64, kernel uses sp_el0 to store current_thread_info(),
we see a problem: when fiq occurs, cpu is EL1 mode but sp_el0
point to userspace address. At this moment, if we read
'current_thread_info()->cpu' or other, it leads an error.

We find above situation happens when save/restore cpu context
between system mode and user mode under heavy load.
Like 'ret_fast_syscall()', kernel restore context of user mode,
but fiq occurs before the instruction 'eret', so this causes the
above situation.

usb: dwc_otg_310: pcd: fix force device mode issue

When tested usb device through force device mode method,
we found that usb device failed to connect to usb host
in the following case.

1. Use micro usb 2.0 OTG interface.
2. Plug in otg cable, and the id pin was pulled down
   to Ground.
3. User space force usb to enter device mode through
   'echo 2 > /sys/bus/platform/drivers/usb20_otg/force_usb_mode'
4. Use usb 2.0 Standard-A to Standard-A cable assembly,
   plug into otg cable receptor on one side, and connect
   to PC on the other side.
5. PC fail to enumerate our device, because of usb driver
   logical issue.

This is because that the dwc_otg_pcd_check_vbus_work()
only enable usb to start connecting if check the bvalid
and iddig is high. But in the above test case, the iddig
is low, so fail to start connection work. In this patch,
we enable usb to connect if iddig is high or usb is in
force device mode.

In addition, fix some coding style to increase the readability.

UPSTREAM: pinctrl: rockchip: Add iomux-route switching support

On the some rockchip SOCS, some things like rk3399 specific uart2 can use
multiple pins. Somewhere between the pin io-cells and the uart it seems
to have some sort of switch to decide to which pin to actually route the
data.

+-------+    +--------+  /- GPIO4_B0 (pinmux 2)

| uart2 | -- | switch | --- GPIO4_C0 (pinmux 2)

+-------+    +--------+  \- GPIO4_C3 (pinmux 2)
(switch selects one of the 3 pins base on the GRF_SOC_CON7[BIT0, BIT1])

The routing switch is determined by one pin of a specific group to be set
to its special pinmux function. If the pinmux setting is wrong for that
pin the ip block won't work correctly anyway.

we still need to check the settings from rockchip_irq_set_type() and we
will use this new rockchip_verify_mux() function from there.

UPSTREAM: pinctrl: rockchip: convert to raw spinlock

This lock is used from rockchip_irq_set_type() which is part of the
irq_chip implementation and thus must use raw_spinlock_t as documented
in Documentation/gpio/driver.txt.

UPSTREAM: pinctrl: rockchip: remove unnecessary locking

regmap_update_bits does its own locking and everything else accessed
here is a local variable so there is no need to lock around it.
