The PWM on the RK3568 with RK628 board has a hardware inverting
circuit to improve drive strength.
Therefore, software needs to change the PWM polarity to get
the desired PWM output.

The mx35lf1ge4ab_get_eccsr() function uses an SPI DMA operation to
read the eccsr, hence the buffer should not be on stack. Since commit
380583227c ("spi: spi-mem: Add extra sanity checks on the op param")
the kernel emmits a warning and blocks such operations.
Use the scratch buffer to get eccsr instead of trying to directly read
into a stack-allocated variable.

Situation for 'i2s-lrck':
Should use flag GPIOD_ASIS not to reclaim LRCK pin as GPIO function,
because we use the same PIN and just read EXT_PORT value which show
the pin status.
Situation for 'tdm-fsync':
A. when the pin is a generic gpio as the ref signal pin which is drived from
external. should use flag GPIOD_IN to reclaim as GPIO_IN function.
B. when the pin is the same pin from the 'clk-src' on the same SoC, we can
use the 'clk-src' fsync out signal as the 'tdm-fsync' to query status.
in this case, should use flag GPIOD_ASIS not to reclaim it as GPIO.

There are clk sync issue on TRCM mode for RK3308/RK1808/PX30,
and the previous soluation is to make TX/RX reset at the same
time to fix that. Unfortunately, it fails on PX30-I2S0, because
the reset-TX and reset-RX bits can't be addressed at the same time.
Now, we use another way to fix it:
reset_control_assert(i2s_tdm->tx_reset);
reset_control_assert(i2s_tdm->rx_reset);
|
gate the i2s src clk
|
reset_control_deassert(i2s_tdm->tx_reset);
reset_control_deassert(i2s_tdm->rx_reset);
|
ungate the i2s src clk
as shown above, use the pair gate/ungate src clk to make the
TX/RX reset at the same time.

TRCM on Master mode require TX/RX enabled at the same time,
or need the one which provide clk enabled at first. In this
situation, one direction's FIFO maybe XRUN which may break
the channels order.
This patch add dmaengine for this mode to handle this situation.
