Input: mtk-pmic-keys - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2022-12-07T21:27:10+00:00

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection
against unused function warnings.  The new combination of pm_sleep_ptr()
and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions,
thus suppressing the warning, but still allowing the unused code to be
removed. Thus also drop the __maybe_unused markings.

Input: mtk-pmic-keys - move long press debounce mask to mtk_pmic_regs

2022-06-01T04:03:45+00:00

As the second and last step of preparation to add support for more
PMICs in this driver, move the long press debounce mask to struct
mtk_pmic_regs and use that in mtk_pmic_keys_lp_reset_setup() instead
of directly using the definition.

While at it, remove the definition for MTK_PMIC_RST_DU_SHIFT as we
are able to calculate it dynamically and spares us some unnecessary
new definitions around for future per-PMIC variations of RST_DU_MASK.

Lastly, it was necessary to change the function signature of
mtk_pmic_keys_lp_reset_setup() to now pass a pointer to the main
mtk_pmic_regs structure, since that's where the reset debounce
mask now resides.

This commit brings no functional changes.

Input: mtk-pmic-keys - transfer per-key bit in mtk_pmic_keys_regs

2022-06-01T04:03:44+00:00

Place the key bit in struct mtk_pmic_keys_regs to enhance this
driver's flexibility, in preparation for adding support for more
PMICs.

While at it, remove the definition of MTK_PMIC_RST_KEY_MASK as
we are now dynamically setting the keymask relatively to the keys
that are defined in the newly added rst_en_mask variable, on a
per-key basis.

This commit brings no functional changes.

Input: mtk-pmic-keys - use single update when configuring long press behavior

2022-06-01T04:03:42+00:00

Instead of doing 3 read-modify-write operations when configuring behavior
of long-press, consolidate everything into one.

MT6358 pmic keys behave differently than mt6397 and mt6323: there are
two interrupts per key: one for press, the other one for release (_r)

Input: mtk-pmic-keys - use get_irq_byname() instead of index

2022-02-08T05:45:17+00:00

Some pmics of the mt6397 family (such as MT6358), have two IRQs per
physical key: one for press event, another for release event.

The mtk-pmic-keys driver assumes that each key only has one
IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping.

This won't work for MT6358, as we have multiple resources (2) for one key.

To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name
instead of by index.

Input: mtk-pmic-keys - add of_node_put() before return

2019-07-12T06:56:05+00:00

Each iteration of for_each_child_of_node puts the previous
node, but in the case of a return from the middle of the loop, there is
no put, thus causing a memory leak. Hence add an of_node_put before the
return in three places.
Issue found with Coccinelle.
