mfd: 88pm886: Constify struct regmap_irq_chip and some other structures2025-05-23T07:49:14+00:00Christophe JAILLETchristophe.jaillet@wanadoo.fr2025-05-11T20:42:30+00:00urn:sha1:950a3c38f73d8167409b2d229ce5139b2be4eff7
'struct regmap_irq_chip' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.
While at it, also constify some other structures.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
5032 3304 64 8400 20d0 drivers/mfd/88pm886.o
After:
=====
text data bss dec hex filename

mfd: 88pm886: Fix wakeup source leaks on device unbind2025-05-23T07:49:06+00:00Krzysztof Kozlowskikrzysztof.kozlowski@linaro.org2025-04-06T19:50:09+00:00urn:sha1:6d0b2398b2638208d68ba06601f776cd5d983b75
Device can be unbound, so driver must also release memory for the wakeup
source.

mfd: Add driver for Marvell 88PM886 PMIC2024-06-28T14:41:05+00:00Karel Balejbalejk@matfyz.cz2024-05-31T17:34:57+00:00urn:sha1:860f8e3beac0b800bbe20f23c5f3440b1c470b8f
Marvell 88PM886 is a PMIC which provides various functions such as
onkey, battery, charger and regulators. It is found for instance in the
samsung,coreprimevelte smartphone with which this was tested. Implement
basic support to allow for the use of regulators and onkey.
