[PATCH v4 0/4] pinctrl: meson-a1: add pinctrl driver

[PATCH v4 0/4] pinctrl: meson-a1: add pinctrl driver

[Qianggui Song]

This patchset adds Pin controller driver support for Meson-A1 Soc
which shares the same register layout of pinmux with previous
Meson-G12A, however there is difference for gpio and pin config
registers in A1.

Changes since v3 at [2]
 - separate ao fixup from meson_pinctrl_parse_dt
 - provide ao extra dt parse callback for each SoC

Changes since v2 at [1]:
 - make dt parser callback as a separate patch

Changes since v1 at [0]:
 - collect Reviewed-by
 - modify commit log
 - add an extra dt parser function for a1

[PATCH v4 1/4] pinctrl: add compatible for Amlogic Meson A1 pin controller

[Qianggui Song]

Add new compatible name for Amlogic's Meson-A1 pin controller
add a dt-binding header file which document the detail pin names.
Note that A1 doesn't need DS bank reg any more, use gpio reg as
base.

[PATCH v4 2/4] pinctrl: meson: add a new callback for SoCs fixup

[Qianggui Song]

In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. Several fixups in the same code make it hard
to maintain, so move all fixups to each SoC's callback and make
meson_pinctrl_parse_dt just do the reg parsing, separate these two
parts.Overview of all current Meson SoCs fixup is as below:

[PATCH v4 3/4] pinctrl: meson: add pinctrl driver support for Meson-A1 SoC

[Qianggui Song]

Meson A1 SoC share the same register layout of pinmux with previous
Meson-G12A, however there is difference for gpio and pin config register
in A1. The main difference is that registers before A1 are grouped by
function while those of A1 are by bank. The new register layout is as
below:

/* first bank */              /* addr */
- P_PADCTRL_GPIOP_I         base + 0x00 << 2
- P_PADCTRL_GPIOP_O         base + 0x01 << 2
- P_PADCTRL_GPIOP_OEN       base + 0x02 << 2
- P_PADCTRL_GPIOP_PULL_EN   base + 0x03 << 2
- P_PADCTRL_GPIOP_PULL_UP   base + 0x04 << 2
- P_PADCTRL_GPIOP_DS        base + 0x05 << 2

Each bank contains at least 6 registers to be configured, if one bank
has more than 16 gpios, an extra P_PADCTRL_GPIO[X]_DS_EXT is included.
Between two adjacent P_PADCTRL_GPIO[X]_I, there is an offset 0x10, that
is to say, for third bank, the offsets will be 0x20,0x21,0x22,0x23,0x24
,0x25 according to above register layout. For previous chips, registers
are grouped according to their functions while registers of A1 are
according to bank.Also note that there is no AO bank any more in A1.

Current Meson pinctrl driver can cover such change by using base address
of GPIO as that of drive-strength. While simply giving reg_ds = reg_pullen
make wrong value to reg_ds for Socs that do not support drive-strength
like AXG.To make things simple, add an extra dt parser function for
a1 and remain the old dt parser function for only reg parsing.

Can you share the definition of this function instead of repeating it ?

Instead of doing this fixup, could modifhy meson_map_ressourse() to
return NULL instead of -ENOENT ?

Then you should IS_ERR_OR_NULL() for "mux" and "gpio" and just IS_ERR()
for the rest

I see there are still comments on the code patches but that is
fine, we can merge these bindings anyway. Just resend the
remaining 3 patches when you repost.

Seems like this common function can only be placed in pinctrl-meson.c, I
will try to write a meson_aobus_parse_dt_extra in pinctrl-meson.c and
assign it to each SoCs  driver before g12a.
