The first patch simply moves some code around to avoid having extern functions declared. The second patch adds support for the SCKC found on sama5d4 and later. It is notably missing the OSC32EN bit. The third patch is an optimization. Trying to find wether the slow oscillator is already stable to avoid waiting 1.2s twice in the boot process. Like discussed on IRC, the clk patches can probably go in v4.9 through the clk tree. I'll take both dtsi patches through the at91 tree for v4.10. Changes in v3: - rebased on clk-next to get the clk_hw rework - use a fixed clock for the rc oscillator on sama5d4 - reordered patches Changes in v2: - Fixed a typo pointed by Boris Alexandre Belloni (5): clk: at91: move slow clock controller clocks to sckc.c clk: at91: Add sama5d4 sckc support clk: at91: sckc: optimize boot time ARM: dts: at91: sama5d4: use proper sckc compatible ARM: dts: at91: sama5d2: use correct sckc compatible .../devicetree/bindings/clock/at91-clock.txt | 3 +- arch/arm/boot/dts/sama5d2.dtsi | 26 +- arch/arm/boot/dts/sama5d4.dtsi | 27 +- drivers/clk/at91/clk-slow.c | 365 ---------------- drivers/clk/at91/sckc.c | 464 ++++++++++++++++++++- drivers/clk/at91/sckc.h | 22 - 6 files changed, 473 insertions(+), 434 deletions(-) delete mode 100644 drivers/clk/at91/sckc.h -- 2.9.3
