pinctrl: mvebu: Fix i2c sda definition for 98DX3236

2020-09-12T16:14:39+00:00

Per the datasheet the i2c functions use MPP_Sel=0x1. They are documented
as using MPP_Sel=0x4 as well but mixing 0x1 and 0x4 is clearly wrong. On
the board tested 0x4 resulted in a non-functioning i2c bus so stick with
0x1 which works.

pinctrl: Use new GPIO_LINE_DIRECTION

2020-02-21T14:19:42+00:00

Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0.

Main benefit is to make it easier to see which values mean IN and which
OUT. As a side effect this helps GPIO framework to change the direction
defines to something else if ever needed.

Please note that return value from get_direction call on
pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have
returned value 2 for direction INPUT.

pinctrl: mvebu: armada-37xx: use use platform api

2020-01-23T15:06:11+00:00

platform_irq_count() and platform_get_irq() is the more generic
way (independent of device trees) to determine the count of available
interrupts. So use this instead.

As platform_irq_count() might return an error code (which
of_irq_count doesn't) some additional handling is necessary.

pinctrl: armada-37xx: Fix irq mask access in armada_37xx_irq_set_type()

2019-11-21T13:54:49+00:00

As explained in the following commit a9a1a4833613 ("pinctrl:
armada-37xx: Fix gpio interrupt setup") the armada_37xx_irq_set_type()
function can be called before the initialization of the mask field.

That means that we can't use this field in this function and need to
workaround it using hwirq.
