The original idea about adding a clock controller is during the discussion in the NAND driver mainline effort[1]. This driver is tested in the S400 board (AXG platform) with NAND driver. Changes since v6 [7]: - add one based support for sclk divier - alloc sclk in probe for multiple instance - fix coding styles Changes since v5 [6]: - remove divider ops with .init and use sclk_div instead - drop CLK_DIVIDER_ROUND_CLOSEST in mux and div - drop the useless type cast Changes since v4 [5]: - use struct parm in phase delay driver - remove 0 delay releted part in phase delay driver - don't rebuild the parent name once again - add divider ops with .init Changes since v3 [4]: - separate clk-phase-delay driver - replace clk_get_rate() with clk_hw_get_rate() - collect Rob's R-Y - drop 'meson-' prefix from compatible string Changes since v2 [3]: - squash dt-binding clock-id patch - update license - fix alignment - construct a clk register helper() function Changes since v1 [2]: - implement phase clock - update compatible name - adjust file name - divider probe() into small functions, and re-use them [1] https://lkml.kernel.org/r/20180628090034.0637a062@xps13 [2] https://lkml.kernel.org/r/20180703145716.31860-1-yixun.lan@amlogic.com [3] https://lkml.kernel.org/r/20180710163658.6175-1-yixun.lan@amlogic.com [4] https://lkml.kernel.org/r/20180712211244.11428-1-yixun.lan@amlogic.com [5] https://lkml.kernel.org/r/20180809070724.11935-4-yixun.lan@amlogic.com [6] https://lkml.kernel.org/r/1539839245-13793-1-git-send-email-jianxin.pan@amlogic.com [7] https://lkml.kernel.org/r/1541089855-19356-1-git-send-email-jianxin.pan@amlogic.com Yixun Lan (3): clk: meson: add emmc sub clock phase delay driver clk: meson: add DT documentation for emmc clock controller clk: meson: add sub MMC clock controller driver clk: meson: add one based divider support for sclk divider .../devicetree/bindings/clock/amlogic,mmc-clkc.txt | 39 +++ drivers/clk/meson/Kconfig | 10 + drivers/clk/meson/Makefile | 3 +- drivers/clk/meson/clk-phase-delay.c | 64 +++++ drivers/clk/meson/clkc-audio.h | 1 + drivers/clk/meson/clkc.h | 13 + drivers/clk/meson/mmc-clkc.c | 313 +++++++++++++++++++++ drivers/clk/meson/sclk-div.c | 28 +- include/dt-bindings/clock/amlogic,mmc-clkc.h | 17 ++ 9 files changed, 477 insertions(+), 11 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/amlogic,mmc-clkc.txt create mode 100644 drivers/clk/meson/clk-phase-delay.c create mode 100644 drivers/clk/meson/mmc-clkc.c create mode 100644 include/dt-bindings/clock/amlogic,mmc-clkc.h
