Vaibhav Hiremath ae0bf3a628 greybus: arche-apb-ctrl: Set wake_detect gpio to low initially ... This patch enables handshaking of AP and SVC using wake_detect gpio (WD_8A and WD_8B). Note that WAKE_DETECT polarity is active-high, so in order to enable handshaking between AP <=> SVC, we need to set wake_detect gpio to low initially, so that driver can send WAKE_DET signal (active-high) to SVC and then SVC can send back WAKE_MOD signal (active-low). And on reception of WAKE_MOD signal, driver would bring respective APB out of reset. WD_8A => APB1 WD_8B => APB2 Signed-off-by: Vaibhav Hiremath <vaibhav.hiremath@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>		2016-01-06 20:03:18 -08:00
