Revision 030b655b062fe5190fc490e0091ea50307d7a86f authored by Risto Suominen on 25 August 2008, 06:04:23 UTC, committed by Takashi Iwai on 02 October 2008, 10:50:37 UTC
Correct headphone detection for 1st generation iMac G3 Slot-loading (Screamer). This patch fixes the regression in the recent snd-powermac which doesn't support some G3/G4 PowerMacs: http://lkml.org/lkml/2008/10/1/220 Signed-off-by: Risto Suominen <Risto.Suominen@gmail.com> Tested-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Cc: stable@kernel.org Signed-off-by: Takashi Iwai <tiwai@suse.de>

* struct i2c_gpio_platform_data - Platform-dependent data for i2c-gpio
* @sda_pin: GPIO pin ID to use for SDA
* @scl_pin: GPIO pin ID to use for SCL
* @udelay: signal toggle delay. SCL frequency is (500 / udelay) kHz
* @timeout: clock stretching timeout in jiffies. If the slave keeps
* SCL low for longer than this, the transfer will time out.
* @sda_is_open_drain: SDA is configured as open drain, i.e. the pin
* isn't actively driven high when setting the output value high.
* gpio_get_value() must return the actual pin state even if the
* pin is configured as an output.
* @scl_is_open_drain: SCL is set up as open drain. Same requirements
* as for sda_is_open_drain apply.
* @scl_is_output_only: SCL output drivers cannot be turned off.
