pinctrl: nomadik: remove dead code after DB8540 pinctrl removal

2022-09-19T07:35:57Z

Commit b6d09f780761 ("pinctrl: nomadik: Drop U8540/9540 support") removes the DB8540 pin controller driver and its config PINCTRL_DB8540. There is some code left-over in the generic nomadik pinctrl driver, i.e., drivers/pinctrl/nomadik/pinctrl-nomadik.{ch}, that is still around for the removed DB8540 pin controller driver. Remove this remaining dead code. This issue was discovered with ./scripts/checkkconfigsymbols.py.

pinctrl: nomadik: Make gpio irqchip immutable

2022-09-19T07:03:03Z

This makes the Nomadik GPIO irqchip immutable. Tested on the Samsung Galaxy SIII mini GT-I8190. Cc: Marc Zyngier Acked-by: Marc Zyngier Link: https://lore.kernel.org/r/20220917203036.167607-2-linus.walleij@linaro.org Signed-off-by: Linus Walleij

pinctrl: nomadik: Dereference gpio_chip properly

2022-09-19T07:02:56Z

The irq data passed to irc_chip handlers i the struct gpio_chip and nothing else. We are just lucky that the nomadik chip pointer is first in the struct. Use the proper dereferencing and helpers.

pinctrl: nomadik: Convert drivers to use struct pingroup and PINCTRL_PINGROUP()

2022-08-25T11:58:38Z

The pin control header provides struct pingroup and PINCTRL_PINGROUP() macro. Utilize them instead of open coded variants in the driver. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20220621112904.65674-1-andriy.shevchenko@linux.intel.com Signed-off-by: Linus Walleij

pinctrl: nomadik: Fix refcount leak in nmk_pinctrl_dt_subnode_to_map

2022-06-15T14:04:01Z

of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak."

pinctrl: nomadik: Setup parent device and get rid of unnecessary of_node assignment

2022-05-04T22:08:06Z

Some of the drivers do not set parent device. This may lead to obstacles during debugging or understanding the device relations from the Linux point of view. Assign parent device for GPIO chips created by these drivers. While at it, let GPIO library to assign of_node from the parent device.

pinctrl: nomadik: Add new MC2 config

2022-04-22T22:01:56Z

The MC2 MMC interface can be configured with the FBCLK (feedback clock) unconnected, leaving the pin available for reuse for something else. Add a group mc2_a_2 for this. Signed-off-by: Linus Walleij Link: https://lore.kernel.org/r/20220418164317.864418-1-linus.walleij@linaro.org

pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe

2022-03-15T01:22:50Z

This node pointer is returned by of_parse_phandle() with refcount incremented in this function. Calling of_node_put() to avoid the refcount leak.

pinctrl: Bulk conversion to generic_handle_domain_irq()

2021-08-12T10:39:39Z

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq(). Acked-by: Krzysztof Kozlowski Acked-by: Linus Walleij Signed-off-by: Marc Zyngier
