We will add a avs driver to adjust opp's voltage according to leakage.
As it need register a notifier before cpufreq starts, and make cpufreq
defer probe is probably not really easy, so avs should probe earlier
than cpufreq, efuse should probe earlier than avs.

According to the dwc2 programmer's guide v3.10a, in '2.1.3.2 Dedicated
FIFO Mode with No Thresholding', it suggested that:
Device RxFIFO =
- Scatter/Gather DMA mode:
(4 * number of control endpoints + 6) + ((largest USB packet used / 4) +
1 for status information) + (2 * number of OUT endpoints) + 1 for Global NAK
on rockchip platforms:
(4 * 1 + 6) + ((1024 / 4) + 1) + (2 * 6) + 1 = 280
- Slave or Buffer DMA mode:
(5 * number of control endpoints + 8) + ((largest USB packet used / 4) +
1 for status information) + (2 * number of OUT endpoints) + 1 for Global NAK
on rockchip platforms:
(5 * 1 + 8) + ((1024 / 4) + 1) + (2 * 6) + 1 = 283
Device IN Endpoint TxFIFO =
The TxFIFO must equal at least one MaxPacketSize (MPS).
In addition to RxFIFO and TxFIFOs, refer to dwc2 databook v3.10a,
'Figure 2-13 Device Mode FIFO Address Mapping and AHB FIFO Access Mapping
(Dedicated FIFO)', it required that when the device is operating in non
Scatter Gather Internal DMA mode, the last locations of the SPRAM are used
to store the DMAADDR values for each Endpoint (1 location per endpoint).
When the device is operating in Scatter Gather mode, then the last locations
of the SPRAM store the Base Descriptor address, Current Descriptor address,
Current Buffer address, and status quadlet information for each endpoint
direction (4 locations per Endpoint). If an Endpoint is bidirectional , then
4 locations will be used for IN, and another 4 for OUT).
Considering that the total FIFO size of dwc2 otg is 0x3cc (972),
and we must reserve (4 * 13) = 52 locations for all Endpoints.
So reconfig dwc2 device fifo size as follows:
Device RxFIFO = 280
Device IN Endpoint TxFIFO
- FIFO #0 = (64 / 4) = 16 (Assuming this is used for EP0)
- FIFO #1 = (1024/4) = 256 (Assuming this is used for Isochronous)
- FIFO #2 = (512/4) = 128
- FIFO #3 = (512/4) = 128
- FIFO #4 = (256/4) = 64
- FIFO #5 = (128/4) = 32
- FIFO #6 = (64/4) = 16
After reconfig the dwc2 device fifo size, test mtp write on rockchip
platform (PC -> rockchip platform) on rk312x/rk3326/px30/rk3288 evb,
when mask the 'vfs_write' in f_mtp.c, the writing data rate can be
increased from 16MBps ~ 20MBps to 30MBps ~ 36MBps on different kinds
of rockchip evbs.

<target min max> voltages. Change cpu opp-microvolt form one entry to
three entries and set maximum acceptable voltage to a high value so that

The vdd_logic is a pwm regulator. Since '#pwm-cells = <2>', there
is not polarity invert support by pwm driver, so we have to add
property 'pwm-dutycycle-range = <100 0>' to support polarity invert
by pwm regulator driver itself.

As the HDMI-audio/codec will cause the hang on bootup, the root
cause that kylin get the invalid master clock from i2s.
$cat/sys/kernel/debug/clk/clk_summary
..
i2s_pre 0 0 0 0 0
sclk_i2s 0 0 0 0 0
i2s_clkout 0 0 0 0 0
Since i2s clock selects io input clock by default, but the hardware
didn't supply the clock.
This patch will fix the sclk_i2s's parent on i2s_frac.
As following:
$cat/sys/kernel/debug/clk/clk_summary
..
i2s_src 1 1 594000000 0 0
i2s_frac 1 1 22579200 0 0
