pinctrl: dove: unset twsi option3 for gconfig as well

2013-12-04T18:55:49+00:00

commit 6d0a4ed2b90a12e1403d3e7d9d8c2cc7fdc301b5 upstream.

This fixes a typo which left twsi config3 option enabled.

pinctrl: at91: fix get_pullup/down function return

2013-09-27T00:18:14+00:00

commit 05d3534a321d7fe4524b3b83bb20318282f3ec2c upstream.

In PIO_PUSR and PIO_PPDSR register if a given bit is set 1 this means the
pullup/down for this pin (pin is represented as a bit position) is
disabled.

Merge tag 'renesas-fixes-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes

2013-06-08T01:11:02+00:00

From Simon Horman, Renesas ARM based SoC fixes for v3.10:
- Correction to USB OVC and PENC pin groupings on r8a7779 SoC.
  This avoids conflicts when the USB_OVCn pins are used by another function.
  This has been observed to be a problem in v3.10-rc1.
- Update CMT clock rating for sh73a0 SoC to resolve boot failure
  on kzm9g-reference. This resolves a regression between v3.9 and v3.10-rc1.

sh-pfc: r8a7779: Don't group USB OVC and PENC pins

2013-06-04T05:37:43+00:00

The USB_OVCn pins are alternate options for USB over-current detection
when using a 3.3V USB interface. As they're not mandatory they can be
used independently of the USB PENC pins. Don't group the USB_OVCn and
PENC pins to avoid conflicts when the USB_OVCn pins are used by another
function.

pinctrl: pinconf: take the right mutex

2013-05-27T13:53:32+00:00

The pinconf_dgb_config_print() takes the per-pincontroller
mutex, when what it wants to take is actually the pin maps
mutex.

pinctrl: sunxi: fix error return code in sunxi_pinctrl_probe()

2013-05-27T13:37:09+00:00

Fix to return a negative error code from the devm_clk_get() error
handling case instead of 0, as done elsewhere in this function.

pinctrl: exynos: Handle suspend/resume of GPIO EINT registers

2013-05-27T13:37:09+00:00

Some GPIO EINT control registers needs to be preserved across
suspend/resume cycle. This patch extends the driver to take care of
this.

pinctrl: samsung: Add support for SoC-specific suspend/resume callbacks

SoC-specific driver might require additional save and restore of

pinctrl: Don't override the error code in probe error handling

2013-05-27T13:37:08+00:00

Otherwise, we return 0 in probe error paths when gpiochip_remove() returns 0.
Also show error message if gpiochip_remove() fails.
