The signal generators provide the ability to set the period, duty cycle, phase offset, and polarity, with new values defaulting to prior values. The period and phase offset are specified in nanoseconds. E.g: period [duty [phase [polarity]]] echo 500000000 > signal # 1/2 second period echo 1000000 40 100 > signal # 1ms period, 40% on, offset 100ns echo 0 > signal # turn off generator Signed-off-by: Jonathan Lemon --- drivers/ptp/ptp_ocp.c | 485 +++++++++++++++++++++++++++++++++++++++++- 1 file changed, 475 insertions(+), 10 deletions(-) diff --git a/drivers/ptp/ptp_ocp.c b/drivers/ptp/ptp_ocp.c index d8dab359f381..f457809879a5 100644 --- a/drivers/ptp/ptp_ocp.c +++ b/drivers/ptp/ptp_ocp.c @@ -179,6 +179,26 @@ struct dcf_slave_reg { #define DCF_S_CTRL_ENABLE BIT(0) +struct signal_reg { + u32 enable;
