* The R40 user manual is self-conflicting on whether the prescaler is
* fixed or configurable. The clock diagram shows it as fixed, but there
H6 has IOSC calibration and an ext-osc32k input. H6 has the osc32k mux and the rtc-32k mux, but no fanout mux. Signed-off-by: Samuel Holland <samuel@sholland.org> --- Changes since v1: - Rebase. - Add a new non-mux "osc32k-fanout" clock instead of changing the number of parents in osc32k_fanout_clk. drivers/clk/sunxi-ng/ccu-sun6i-rtc.c | 49 ++++++++++++++++++++++++++++ drivers/rtc/rtc-sun6i.c | 17 ---------- 2 files changed, 49 insertions(+), 17 deletions(-)
