there is already uart_ao_rx_a_pins[] uart_ao_tx_a_pins[] , see

794 static const unsigned int uart_ao_tx_a_pins[] = {
GPIOAO_0 };
795 static const unsigned int uart_ao_rx_a_pins[] = {
GPIOAO_1 };

in the G12A ASIC design, some AO device (from function perspective)
route the pin to EE domain, for maximize pin mux utilization.

if you don't like this naming scheme, I could rename it into
uart_ao_rx_a_ee_pins[]
uart_ao_tx_a_ee_pins[]

which mean uart_ao rx pin at port A route to EE domain's physical pin.

I'd prefer the original version, which mean cec_ao controller at port a
route to EE domain's physical pin.

I would check this driver to see if there is inconsistency.

After talking to Xingyu, this naming is actually taken from the pin mux
documentation, it's BT565_A there.

I'm not sure if you insist to drop the _a suffix, personally I'd just
leave it as it is, for better consistence with documentation.

there are a few comments relate to tdm iteam, let me rephase as
following, see if it's correct

we could divide tdm funtion into four part (same in pinctrl driver):
a) tdm clk
b) tdm data out
c) tdm clk slv
d) tdm data in

the combination can be like this from the use case perspective:
a + b, a + d, c + b, c + d

so in this patch, we could write as
tdm_ao_b_clk_groups[]
tdm_ao_b_clk_slv_groups[]
tdm_ao_b_data_in_groups[]
tdm_ao_b_data_out_groups[]

look into the pin mux documentation, the tdm_ao_b clock function is set
by value=5, while tdm_ao_b clock_slv functioin is set by value=6.

I'm confused here, just checked the naming scheme, previous
in gxbb, gxl, we use:
drivers/pinctrl/meson/pinctrl-meson-gxbb.c
line 267: uart_tx_ao_a_pins[]

in axg (code I pushed), use:
drivers/pinctrl/meson/pinctrl-meson-axg.c
line 225: uart_ao_tx_b_z_pins[]

I do not against to change the naming scheme, so long as we could reach
a agreement first, and if we do the change, should we fix the old code?
(which will cause the DT change)

it's special mode from pwm, so there are two mode: pwm, hiz pwm (hi/low
mode)

normal pwm:

|--| |--|
| | | |
___| |__| |__

a) hi/hiz mode:

---\ |--\
___| \__| \__

b) low/hiz mode:

/--| /--|
___/ |__/ |__
