pinctrl: at91-pio4: fix pull-up/down logic

2016-04-29T09:16:19Z

The default configuration of a pin is often with a value in the pull-up/down field at chip reset. So, even if the internal logic of the controller prevents writing a configuration with pull-up and pull-down at the same time, we must ensure explicitly this condition before writing the register. This was leading to a pull-down condition not taken into account for instance.

pinctrl: single: Fix pcs_parse_bits_in_pinctrl_entry to use __ffs than ffs

2016-04-15T09:26:55Z

pcs_parse_bits_in_pinctrl_entry uses ffs which gives bit indices ranging from 1 to MAX. This leads to a corner case where we try to request the pin number = MAX and fails. bit_pos value is being calculted using ffs. pin_num_from_lsb uses bit_pos value. pins array is populated with: pin + pin_num_from_lsb. The above is 1 more than usual bit indices as bit_pos uses ffs to compute first set bit. Hence the last of the pins array is populated with the MAX value and not MAX - 1 which causes error when we call pin_request. mask_pos is rightly calculated as ((pcs->fmask) << (bit_pos - 1)) Consequently val_pos and submask are correct. Hence use __ffs which gives (ffs(x) - 1) as the first bit set. fixes: 4e7e8017a8 ("pinctrl: pinctrl-single: enhance to configure multiple pins of different modules") Signed-off-by: Keerthy Acked-by: Tony Lindgren Signed-off-by: Linus Walleij

pinctrl: mediatek: correct debounce time unit in mtk_gpio_set_debounce

2016-04-15T08:28:04Z

The debounce time unit for gpio_chip.set_debounce is us but mtk_gpio_set_debounce regard it as ms. Fix this by correct debounce time array dbnc_arr so it can find correct debounce setting. Debounce time for first debounce setting is 500us, correct this as well. While I'm at it, also change the debounce time array name to "debounce_time" for readability.

pinctrl: imx: Kconfig: PINCTRL_IMX select REGMAP

2016-04-14T12:19:00Z

Regmap functionality has been integrated into pinctrl-imx.c with commit 8626ada8 which might trigger build failures when regmap is not selected otherwise. Hence, make Kconfig aware about this new dependency. Signed-off-by: Alexander Kurz Acked-by: Philipp Zabel Acked-by: Shawn Guo Signed-off-by: Linus Walleij

pinctrl: intel: implement gpio_irq_enable

2016-03-30T08:57:52Z

There is unexpected gpio interrupt after irq_enable. If not implemeted gpio_irq_enable callback, irq_enable calls irq_unmask instead. But if there was interrupt set before the irq_enable, unmask it may trigger the unexpected interrupt. By implementing the gpio_irq_enable callback, do interrupt status ack, the issue has gone.
