pinctrl: bcm2835: Fix memory leak in error path

2016-02-02T19:38:16+00:00

commit 53653c6b91750debba6dc4503003c851257fd340 upstream.

In case of an invalid pin value bcm2835_pctl_dt_node_to_map()
would leak the pull configs of already assigned pins.
So avoid this by calling the free map function in error case.

pinctrl: bcm2835: Fix initial value for direction_output

2016-01-25T10:43:48+00:00

commit 4c02cba18cc9de672a554ddda4f23dec8cb4b48e upstream.

Currently the provided initial value for bcm2835_gpio_direction_output
has no effect. So fix this issue by changing the value before
changing the GPIO direction. As a result we need to move the function below
bcm2835_gpio_set.

pinctrl: mvebu: armada-38x: fix incorrect total number of GPIOs

2015-07-15T09:00:30+00:00

commit 27e7cd016558bf787b128fd882cdd90409ae4036 upstream.

The pinctrl_gpio_range[] array described a first bank of 32 GPIOs and
a second one of 27 GPIOs. However, since there is a total of 60 MPP
pins that can be muxed as GPIOs, the second bank really has 28 GPIOs.

pinctrl: mvebu: armada-375: remove incorrect space in pin description

2015-07-15T09:00:29+00:00

commit d538990ee12b162f7ce6c0fcef3b643800102676 upstream.

There was an incorrect space in the definition of the function of one
pin in the Armada 375 pinctrl driver, which this commit fixes.

pinctrl: mvebu: armada-xp: fix functions of MPP48

2015-07-15T09:00:29+00:00

commit ea78b9511a54d0de026e04b5da86b30515072f31 upstream.

There was a mistake in the definition of the functions for MPP48 on
Marvell Armada XP. The second function is dev(clkout), and not tclk.

pinctrl: mvebu: armada-xp: remove non-existing VDD cpu_pd functions

2015-07-15T09:00:28+00:00

commit 80b3d04feab5e69d51cb2375eb989a7165e43e3b upstream.

The latest version of the Armada XP datasheet no longer documents the
VDD cpu_pd functions, which might indicate they are not working and/or
not supported. This commit ensures the pinctrl driver matches the
datasheet.

pinctrl: mvebu: armada-xp: remove non-existing NAND pins

2015-07-15T09:00:28+00:00

commit bc99357f3690c11817756adfee0ece811a3db2e7 upstream.

After updating to a more recent version of the Armada XP datasheet, we
realized that some of the pins documented as having a NAND-related
functionality in fact did not have such functionality. This commit
updates the pinctrl driver accordingly.

pinctrl: mvebu: armada-370: fix spi0 pin description

2015-07-15T09:00:27+00:00

commit 438881dfddb9107ef0eb30b49368e91e092f0b3e upstream.

Due to a mistake, the CS0 and CS1 SPI0 functions were incorrectly
named "spi0-1" instead of just "spi0". This commit fixes that.

This DT binding change does not affect any of the in-tree users.

pinctrl: mvebu: armada-38x: fix PCIe functions

2015-07-15T09:00:26+00:00

commit 331642fbf24a1c16b2669ca0a6479b5fcd6dd5b2 upstream.

A new revision of the Marvell Armada 38x hardware datasheet unveiled
that the definition of some of the PCIe functions were not
correct. This commit fixes the pinctrl driver accordingly.

Some PCIe functions simply do not exist, some of the PCIe functions in
fact were corresponding to other functions, and some PCIe functions
have been added.

Note: the seemingly unrelated removal of spi(cs2) on MPP47 is related:
this function is in fact implemented on MPP43, instead of a PCIe
function.
