Zram allows Linux to make more efficient use of RAM, since
the system can then hold more pages of memory in the compressed
swap than if the same amount of RAM had been used as application
memory or disk cache. This is particularly effective on machines
that do not have much ram space.
Enable:
echo 16M > /sys/block/zram0/disksize
mkswap /dev/zram0
swapon /dev/zram0

so we need be compatible with the old regulator name of cpu.

We may need to support a variety of different Bluetooth modules
which are from different vendors. In order to develop efficiently,
we need to uniformly set the PCM of the AP to master mode, and
the Bluetooth side as the slave.

nvme for rockchip platform could be used as both of main disk
or external storage. So it's not proper to fix the partition
type by checking CONFIG_ARCH_ROCKCHIP. Otherwise, if the nvme
is probed earily then the real main disk device, then the main
disk could be failed to mount.

The usb otg doesn't need phy node, because it uses
legacy controller driver "dwc_otg_310". But the phy
node is needed for uboot which uses kernel dtb. And
it's also useful for otg controller driver if we
switch to dwc2 driver later.

This patch adds rk3368 otg-port phy configurations.
But actually, we don't use the otg phy configurations
for the time being, because we use dwc_otg_310 driver
for rk3368 otg controller, and this driver doesn't use
generic phy. This patch is useful if we switch to dwc2
driver for rk3368 otg in the feature.

The PWM framework has clarified the concept of reference PWM config (the
platform dependent config retrieved from the DT or the PWM lookup table)
and real PWM state.
Use pwm_get_args() when the PWM user wants to retrieve this reference
config and not the current state.
This is part of the rework allowing the PWM framework to support
hardware readout and expose real PWM state even when the PWM has just
been requested (before the user calls pwm_config/enable/disable()).

When prepare setup packet, don't clear nak before call
ep0_out_start(), because clear nak will make the usb
core to handle OUT transaction immediately without
NAK response, this may cause OUT transaction fail.
We can reproduce this issue in the following two case:
- Configure usb device as rndis, connect to Windows PC;
- Configure usb device as uvc, connect to Windows PC,
and take still image;
Use the usb analyzer to capture data in case2，we can
easily to find the problem.
Without this patch, the Class request OUT transfer is:
- SETUP transaction
- OUT transaction
- OUT packet
- DATA1 packet
- ACK pakcet
- IN transactions
- IN packet
- NAK packet (response NAK forever)
With this patch, the Class request OUT transfer is:
- SETUP transaction
- OUT transaction
- OUT packet
- DATA1 packet
- NAK packet
- PING transactions
- OUT transaction
- OUT packet
- DATA1 packet
- ACK pakcet
- IN transaction
- IN packet
- DATA1 packet

The frame num of isoc ep is initialized to 0xFFFFFFFF in
ep_enable and start_next_request(), and then in the NAK
interrupt handler, it will check if the ep frame num is
0xFFFFFFFF, then reset the frame num to 0 and start next
request.
But if we dequeue the isoc ep request if it's already
enqueued, if may fail to call complete_ep() -> start_
next_request(), so the isoc ep frame num can't be reinit
to 0xFFFFFFFF, this cause NAK interrupt handler check
the frame num incorrectly, and fail to start next request.
