At boot, this clock does not have a default parent nor a default rate set. Thus we should be able to change its parent to get this clock working. The current clock implementation is using a mux to select the parent, but these clocks need to add a password (0x5a) in higher register bits when changing parent. So a generic mux cannot be used here. The two first patches fix the clock parent selection, while the second one is actually adding the pwm clock registration. Changes since v1: - determine_rate now based its parent selection upon divided rate instead of the parent one - bcm2835_clock_choose_div has been modified to produce an avarage rate lower or equal to the requested one - devicetree modifications have removed to be send in another patch Remi Pommarel (3): clk: bcm2835: Always round up clock divisor clk: bcm2835: Support for clock parent selection clk: bcm2835: Add PWM clock support drivers/clk/bcm/clk-bcm2835.c | 151 +++++++++++++++++++++++------------- include/dt-bindings/clock/bcm2835.h | 3 +- 2 files changed, 101 insertions(+), 53 deletions(-) -- 2.0.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
