The otg id voltage is provided from usb2 phy power. On some
rockchip platforms (e.g. rk3399), the usb2 phy power will be
turned off when enter pm suspend, this will trigger id fall
interrupt. But current code enable the ID interrupt consistently,
it may result in the mistake of ID changing operation even if
the state of ID pin is not changed. So disable ID irq when
suspend and enable when resume.

The plat_data->input_bus_format and plat_data->input_bus_encoding
are unsigned long and are always >=0, but the value 0 was still
considered as RGB888 for input_bus_format and default color space
for input_bus_encoding in the reworked code.
This patch changes the if statement check for a non-zero value to
either use the default input bus_format and/or bus_encoding for a zero
value and the provided bus_format and/or bus_encoding for a
non zero value.
Thanks to Dan Carpenter for his bug report at [1].
Tested on Amlogic P230 (with CSC enabled for YUV444 to RGB) and Rockchip
RK3288 ACT8846 EVB Board (no CSC involved, direct RGB passthrough).

(cherry picked from commit e20c29aa72)
Switch code to use the newly introduced V4L bus formats IDs instead of custom
defines. Also use the V4L encoding defines.
Some display pipelines can only provide non-RBG input pixels to the HDMI TX
Controller, this patch takes the pixel format from the plat_data if provided.

First, write hdcp key by "ProvisioningTool" if you want to
enable hdcp function, or else will auth fail.
To check whether the hdcp is enable or not
#cat /sys/class/misc/hdmi_hdcp1x/enable
0:hdcp is disabled
1:hdcp is enabled, hdmi screen will be pink if it is failed;
2:hdcp is enabled, hdmi screen will be normal if it is failed;
Enable or disable hdcp function
#echo 0 > /sys/class/misc/hdmi_hdcp1x/enable
#echo 1 > /sys/class/misc/hdmi_hdcp1x/enable
#echo 2 > /sys/class/misc/hdmi_hdcp1x/enable
Get the status of hdcp
#cat /sys/class/misc/hdmi_hdcp1x/status
The result will be one of the follow list:
hdcp disable;
hdcp_auth_start
hdcp_auth_success;
hdcp_auth_fail;
unknown status.

In order to get lower jitter clock for hdmi tmds, Hardware
design that: direct get tmds clock from vpll, bypass vop.
This design can make hdmi good works, but also limit hdmi's
clock source, the vop which hdmi use need also assign to vpll,
and use same clock rate, it's hardware limitation.
This patch add a mechanism to select dclk's parent pll, then
can allocate correct pll for hdmi.

dmaengine_prep_dma_cyclic, to use buf_addr with size buf_len,
generate an interrupt every period_len. But DMA must restart
every period_len, it may be blocked. If i2s use it, it may
cause sound break. Infiniteloop is helpful to solve this
issue. In infiniteloop mode, when DMA transfers all buf_len
data, it goes back to the start of buf_addr and continue to
transfer endless.

Because we have supported to force otg mode for rk3328 in the commit
2b9b897141f1 ("phy: rockchip-inno-usb2: support to force otg mode"),
so let's config dr_mode as otg for usb otg port, and then user can
use otg peripheral mode and host mode as needed.

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
