Revert "pinctrl: bcm: ns: support updated DT binding as syscon subnode"

2021-11-02T18:50:51+00:00

commit 6dba4bdfd7a30e77b848a45404b224588bf989e5 upstream.

This reverts commit a49d784d5a8272d0f63c448fe8dc69e589db006e.

The updated binding was wrong / invalid and has been reverted. There
isn't any upstream kernel DTS using it and Broadcom isn't known to use
it neither. There is close to zero chance this will cause regression for
anyone.

Actually in-kernel bcm5301x.dtsi still uses the old good binding and so
it's broken since the driver update. This revert fixes it.

pinctrl: bcm: Constify static pinmux_ops

2021-06-09T09:18:33+00:00

These are only assigned, either directly or via the bcm63xx_pinctrl_soc
struct, to the pmxops field in the pinctrl_desc struct and never
modified, so make them const to allow the compiler to put them in
read-only memory.

pinctrl: bcm2835: Accept fewer than expected IRQs

2021-05-28T00:56:13+00:00

The downstream .dts files only request two GPIO IRQs. Truncate the
array of parent IRQs when irq_of_parse_and_map returns 0.

pinctrl: iproc-gpio: Remove redundant error printing in iproc_gpio_probe()

2021-05-19T23:37:32+00:00

When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.

Therefore, remove the error printing here to simplify code and reduce the
binary size.

The additional patch below fixes all of the kconfig warnings and
build errors for me.

pinctrl: bcm63xx: Fix dependencies

2021-03-31T12:45:05+00:00

Add depends on OF so we don't get weird build errors on
randconfig.

Also order selects the same as the other drivers for
pure aestetic reasons.

pinctrl: bcm: bcm6362: fix warning

2021-03-31T12:33:48+00:00

The current implementation of bcm6362_set_gpio() produces the following
warning on x86_64:
drivers/pinctrl/bcm/pinctrl-bcm6362.c: In function 'bcm6362_set_gpio':
drivers/pinctrl/bcm/pinctrl-bcm6362.c:503:8: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  503 |        (uint32_t) desc->drv_data, 0);
      |        ^

Modify the code to make it similar to bcm63268_set_gpio() in order to fix
the warning.

pinctrl: add a pincontrol driver for BCM6318

2021-03-29T10:20:09+00:00

Add a pincontrol driver for BCM6318. BCM6318 allows muxing most GPIOs
to different functions. BCM6318 is similar to BCM6328 with the addition
of a pad register, and the GPIO meaning of the mux register changes
based on the GPIO number.

Add a pincontrol driver for BCM63268. BCM63268 allows muxing GPIOs
to different functions. Depending on the mux, these are either single
pin configurations or whole pin groups.
