Subject: [PATCH 0/3] Add support for RK3588 HDMI/DP Combo PHY

Add driver and bindings to support the Rockchip HDMI/eDP TX Combo PHY
found on RK3588 SoC.

The PHY is based on a Samsung IP block and supports HDMI 2.1 TMDS, FRL
and eDP links.

The HDMI link has been tested on Rock 5B and EVB1 boards.

Subject: [PATCH 3/3] phy: rockchip: Add Samsung HDMI/DP Combo PHY driver

Add driver for the Rockchip HDMI/eDP TX Combo PHY found on RK3588 SoC.

The PHY is based on a Samsung IP block and supports HDMI 2.1 TMDS, FRL
and eDP links. The maximum data rate is 12Gbps (HDMI 2.1 FRL), while
the minimum is 250Mbps (HDMI 2.1 TMDS).

The driver has multiple sequences looking like this (this is just one
example of many):

Instead of the repetitive calls to regmap_write, it's better to do
it like this:

static const struct reg_sequence some_init_seq[] = {
REG_SEQ0(CMN_REG0087, 0x04),
REG_SEQ0(CMN_REG0089, 0x00),
REG_SEQ0(CMN_REG008A, 0x55),
REG_SEQ0(CMN_REG008B, 0x25),
REG_SEQ0(CMN_REG008C, 0x2c),
REG_SEQ0(CMN_REG008D, 0x22),
REG_SEQ0(CMN_REG008E, 0x14),
REG_SEQ0(CMN_REG008F, 0x20),
REG_SEQ0(CMN_REG0090, 0x00),
REG_SEQ0(CMN_REG0091, 0x00),
REG_SEQ0(CMN_REG0092, 0x00),
REG_SEQ0(CMN_REG0093, 0x00),
REG_SEQ0(CMN_REG0095, 0x00),
REG_SEQ0(CMN_REG0097, 0x02),
REG_SEQ0(CMN_REG0099, 0x04),
REG_SEQ0(CMN_REG009A, 0x11),
REG_SEQ0(CMN_REG009B, 0x00),
};

regmap_multi_reg_write(hdptx->regmap, some_init_seq, ARRAY_SIZE(some_init_seq));

Remove of_match_ptr(). It's a nop, since the driver depends on OF.

Thanks for the hint! Will try to make use of this as much as possible.

Right, will drop it in v2.

I missed to highlight there is no eDP support provided by the current
implementation. Downstream kernel has a separate driver for that and at
the moment I don't have the hardware to wire this up.

Will include this statement in v2.

+1 on that.

It' quite hard currently to figure out what the driver is _actually_ doing
as it has all this hardcoded sequences mixed up with driver logic. Better
move them at the top as arrays and use regmap_multi_reg_write as Sebastian
suggests.

The PHY is used for HDMI and eDP on rk3588, and should used be exclusively.
so I think should s/DP/eDP/ in all description.

These register names are not particularly helpful. Maybe use a

#define CMN_REG(x) ((x) * 4)

Instead?

You could use ARRAY_SIZE() to iterate over the array and save the extra
entry at the end. Likewise for the other arrays used in the driver.

What is going on here? bus_width is set to 8 in probe() using
phy_set_bus_width(), but the value you pull out of phy_get_bus_width()
is expected to contain the bit_rate and several other flags.

It looks like you are tunneling flags from some other driver using this
field. Isn't there a better way to accomplish this? If not, I think this
needs some explanation.

At least the variable should be renamed. it's called "bus_width" and it's
passed to functions like hdptx_lcpll_frl_mode_config() which has this
parameter named "rate" which is quite confusing.

Here use phy->attrs.bus_width to indicate different work mode,
we also use the same in our bsp, but not sure if it is the appropriate way.

Yes, sounds good.

Indeed, sorry for missing a comment here. The flags are set by the
bridge driver to enable 10-bit color depth, FRL and EARC. So far I
couldn't find an alternative approach to pass custom data using the PHY API.

I think for the initial support it's not really necessary to implement
all those features. Andy, should we drop them until a better solution
is found?

Right, will make this consistent.

I'm fine with it.
It would be very appreciated if some linux-phy or drm bridge experts can give
some suggestions about how to pass different custom phy modes.

Please see the patch "phy: Add HDMI configuration options" [1] from
Sandor Yu. Also the series "drm/connector: Create HDMI Connector
infrastructure" [2] from Maxime Ripard may be of interest.
