pinctrl: nomadik: Fix refcount leak in nmk_pinctrl_dt_subnode_to_map

2022-06-15T14:04:01+00:00

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

2022-05-04T22:08:06+00:00

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

2022-04-22T22:01:56+00:00

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.

pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe

2022-03-15T01:22:50+00:00

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()

2021-08-12T10:39:39+00:00

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().

pinctrl: nomadik: Remove unused variable in nmk_gpio_dbg_show_one

2021-01-05T23:20:14+00:00

Clang warns:

drivers/pinctrl/nomadik/pinctrl-nomadik.c:952:8: warning: unused
variable 'wake' [-Wunused-variable]
                bool wake;
                     ^
1 warning generated.

There were two wake declarations added to nmk_gpio_dbg_show_one when
converting it to use irq_has_action but only one is used within its
scope. Remove the unused one so there is no more warning.

Merge tag 'irq-core-2020-12-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2020-12-24T21:50:23+00:00

Pull irq updates from Thomas Gleixner:
 "This is the second attempt after the first one failed miserably and
  got zapped to unblock the rest of the interrupt related patches.

  A treewide cleanup of interrupt descriptor (ab)use with all sorts of
  racy accesses, inefficient and disfunctional code. The goal is to
  remove the export of irq_to_desc() to prevent these things from
  creeping up again"

pinctrl: nomadik: db8500: Add more detailed LCD groups

2020-11-11T08:56:05+00:00

We need a more granular distribution among funcion A
and function B for the LCD pins for the Samsung
GT-I9070. Provide some new pin groups so we can
configure this phone properly.
