[PATCH v3 01/10] pinctrl: Ingenic: Add missing pins to the JZ4770 MAC MII group.

[周琰杰 (Zhou Yanjie)]

The MII group of JZ4770's MAC should have 7 pins, add missing
pins to the MII group.

Fixes: 5de1a73e78ed ("Pinctrl: Ingenic: Add missing parts for JZ4770 and JZ4780.")

[PATCH v3 06/10] pinctrl: Ingenic: Add pinctrl driver for JZ4730.

[周琰杰 (Zhou Yanjie)]

Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.

This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

Re: [PATCH v3 01/10] pinctrl: Ingenic: Add missing pins to the JZ4770 MAC MII group.

Hi Zhou,


Le mer. 17 mars 2021 à 17:57, 周琰杰 (Zhou Yanjie) 
<zhouyanjie@wanyeetech.com> a écrit :
> The MII group of JZ4770's MAC should have 7 pins, add missing

This fixes a commit that was introduced in an older kernel (than the 
one in -rc phase). Therefore you need to Cc linux-stable. Like this:

Cc: <stable@vger.kernel.org> # v5.0

> Signed-off-by: 周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>

With that said:

I had to look up operator precedence in C, '*' and '%' have the same 
priority so this reads left-to-right.

I'd suggest adding parentheses around the '%' to make it more obvious.

With that:

While we're at it, the JZ4725B has also 4 GPIO ports.

Two things:

- this is only used on the JZ4730, so please change the function name 
to something like "jz4730_gpio_set_bits". And the 
"ingenic_gpio_set_bits" is too close to the already existing 
"ingenic_gpio_set_bit" which would get pretty confusing.

- multi-line comments should have the opening /* on its own line. 
scripts/checkpatch.pl should have warned about that.

You can do:

unsigned int mask = GENMASK(1, 0) << idx * 2;

regmap_update_bits(jzgc->jzpc->map, jzgc->reg_base + reg,
                   mask, FIELD_PREP(mask, value));

This would look better:

I'd prefer:

        regmap_write(jzpc->map, offt * jzpc->info->reg_offset +

    else
        regmap_clear_bits(jzpc->map, offt * jzpc->info->reg_offset +

Same two remarks as above (about the function name and multi-lines

Same as above with GENMASK and FIELD_PREP.

'func' is in the [0..3] range already, so you can drop the & 0x3 mask.

Please drop "lcd-no-pins" from your patches, it is pointless.

Coud you either split this into several groups (lcd-8bit, lcd-16bit, 
lcd-18bit, lcd-24bit, lcd-special, lcd-generic) like it is done for the 
JZ4725B? Same for the other SoCs.

Alternatively just remove the "lcd" function for now.

And remove this.

You should have these groups: lcd-8bit, lcd-16bit, lcd-18bit, 
lcd-24bit, lcd-generic, lcd-special.

Your lcd-slcd-16bit would then be lcd-8bit + lcd-16bit. (non-SLCD 
panels would need lcd-generic as well).

Like on the other patches, please drop this.

val3 = type == IRQ_TYPE_EDGE_BOTH;

then you don't need to initialize val3 on each case of the switch.

Was that even tested? Your "bias" value is one of GPIO_PULL_DIS, 
GPIO_PULL_UP or GPIO_PULL_DOWN, you can't match it against values of 
the pin_config_param enum and expect it to work.

Sure, and do we need to change the JZ4740 (and the previous JZ4750) to 
the lcd-special + lcd-generic model? It looks more reasonable than the 
original lcd-tft and makes the style more uniform.

Yes, please change it for the JZ4750 too.

For the JZ4740, in theory it is too late - these are ABI and we 
shouldn't change them.

With that said - the only board that has a JZ4740 and is still 
supported (although untested, so it's not even sure it still boots) is 
the Ben Nanonote, which only uses the "lcd-8bit" group. So it's 
probably fine.

In case of the X2000 (and maybe X1830 - didn't check), the RGB and SLCD 
modules have pins in common, but with a different function number. As 
such they don't actually share any group of pins, and should be 
distinguised, yes.

You can split the RGB part the same way it's done for the JZ47xx SoCs. 
For the SLCD, according to the PM it supports 1-bit, 8-bit, 9-bit, 
16-bit, 18-bit and 24-bit, so you should have groups for these.
