This driver will add a MMC clock controller driver support. 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 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@xxxxxxxxxxx [3] https://lkml.kernel.org/r/20180710163658.6175-1-yixun.lan@xxxxxxxxxxx [4] https://lkml.kernel.org/r/20180712211244.11428-1-yixun.lan@xxxxxxxxxxx [5] https://lkml.kernel.org/r/20180809070724.11935-4-yixun.lan@xxxxxxxxxxx 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 .../devicetree/bindings/clock/amlogic,mmc-clkc.txt | 31 +++ drivers/clk/meson/Kconfig | 10 + drivers/clk/meson/Makefile | 3 +- drivers/clk/meson/clk-phase-delay.c | 79 ++++++ drivers/clk/meson/clk-regmap.c | 27 +- drivers/clk/meson/clk-regmap.h | 1 + drivers/clk/meson/clkc.h | 13 + drivers/clk/meson/mmc-clkc.c | 296 +++++++++++++++++++++ include/dt-bindings/clock/amlogic,mmc-clkc.h | 17 ++ 9 files changed, 475 insertions(+), 2 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 -- 1.9.1
