pinctrl: protect pinctrl_list add

2014-02-20T19:08:02Z

commit 7b320cb1ed2dbd2c5f2a778197baf76fd6bf545a upstream. We have few fedora bug reports about list corruption on pinctrl, for example: https://bugzilla.redhat.com/show_bug.cgi?id=1051918 Most likely corruption happen due lack of protection of pinctrl_list when adding new nodes to it. Patch corrects that.

pinctrl: vt8500: Change devicetree data parsing

2014-02-20T19:08:02Z

commit f17248ed868767567298e1cdf06faf8159a81f7c upstream. Due to an assumption in the VT8500 pinctrl driver, the value passed from devicetree for 'wm,pull' was not explicitly translated before being passed to pinconf. Since v3.10, changes to 'enum pin_config_param', PIN_CONFIG_BIAS_PULL_(UP/DOWN) no longer map 1-to-1 with the expected values in devicetree. This patch adds a small translation between the devicetree values (0..2) and the enum pin_config_param equivalent values.

pinctrl: at91: use locked variant of irq_set_handler

2014-02-20T19:08:02Z

commit b0dcfd87323ea86501e93d0fa2a98d2fd3579bcf upstream. When setting the gpio irq type, use the __irq_set_handler_locked() variant instead of the irq_set_handler() to prevent false spinlock recursion warning.

pinctrl: sunxi: Honor GPIO output initial vaules

2014-02-06T19:22:18Z

commit fa8cf57c923e86a693a85aff1df579245a27cbb3 upstream. Some GPIO users, such as fixed-regulator, request GPIO output with initial value of 1. This was ignored by sunxi driver. Signed-off-by: Chen-Yu Tsai Acked-by: Maxime Ripard Signed-off-by: Linus Walleij Signed-off-by: Greg Kroah-Hartman

Revert "ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs"

2014-01-25T16:49:28Z

commit 2b844ba79f4a114bd228ad6fee040ffd99a0963d upstream. This reverts commit f6308b36c411 (ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs), because it causes the Alan Cox' ASUS T100TA to "crash and burn" during boot if the Baytrail pinctrl driver is compiled in.

sh-pfc: Fix PINMUX_GPIO macro

2014-01-09T20:25:15Z

commit 8620f394c4f9abd13e4fdf927d9c2bbeda74cde7 upstream. Commit 7cbb0e55e27e ("sh-pfc: Don't duplicate argument to PINMUX_GPIO macro") erronesouly modified the PINMUX_GPIO macro in a way that resulted in all pins being named "name". Fix the macro to name the pins correctly. Cc: stable@vger.kernel.org Signed-off-by: Laurent Pinchart Signed-off-by: Linus Walleij Signed-off-by: Greg Kroah-Hartman

ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs

2014-01-09T20:25:09Z

commit f6308b36c411dc5afd6a6f73e6454722bfde57b7 upstream. This adds the new ACPI ID (INT33FC) for the BayTrail GPIO banks as seen on a BayTrail M System-On-Chip platform. This ACPI ID is used by the BayTrail GPIO (pinctrl) driver to manage the Low Power Subsystem (LPSS). Signed-off-by: Paul Drews Acked-by: Linus Walleij Signed-off-by: Rafael J.

pinctrl: dove: unset twsi option3 for gconfig as well

pinctrl: palmas: do not abort pin configuration for BIAS_DEFAULT

2013-09-27T14:22:43Z

Recent movement of all configurations of pin in the single call of pin_config_set(), it is aborting configuration if BIAS_PULL_PIN_DEFAULT is selected as return of configuration. The original idea was to just avoid any update on register for pull up/down configuration if this option is selected. Fixing this by just bypassing any register update for BIAS_PULL_PIN_DEFAULT and continuing the remaining configuration. Signed-off-by: Laxman Dewangan Signed-off-by: Linus Walleij
