Thanks, I will resolve it, I want make sure for it.
I should take the "periphs_xtal" clock in ee g12a clock controller driver through DT , And then I can get its clock name "xtal" by property of clock-output-names. Is that right?
ee g12a clock dts:
hiubus: bus@ff63c000 { compatible = "simple-bus"; reg = <0x0 0xff63c000 0x0 0x1c00>; #address-cells = <2>; #size-cells = <2>; ranges = <0x0 0x0 0x0 0xff63c000 0x0 0x1c00>;
sysctrl: syscon@0 { compatible = "amlogic,meson-g12a-hhi-sysctrl", "simple-mfd", "syscon"; reg = <0x0 0x0 0x0 0x400>;
clkc: clock-controller { compatible = "amlogic,g12a-clkc"; #clock-cells = <1>; clocks = <&xtal>; clock-name = "periphs_xtal"; }; }; };
xtal: xtal-clk { compatible = "fixed-clock"; clock-frequency = <24000000>; clock-output-names = "xtal";
#clock-cells = <0>; }; >> >> Changes since v2 at[2] >> -fix fixed clocks's descriptions >> -fix aligment >> -add enable bit for plls base on [3] patches >> -add fixed clock gate bit >> >> Changes since v1 at[1] >> -fix typo of 'Everything'. >> -change the word 'AmLogic' to 'Amlogic' >> -squash patch 1 and 2. >> -delete usless message of "Trying obsolete regs". >> -delete the empty line in include/dt-bindings/clock/g12a-clkc.h. >> -rebase on top of the "next/drivers" branch, and add g12a clock patch. >> -add CLK_MUX_ROUND_CLOSEST for g12a_sd_emmc_b_clk0_sel and >> g12a_sd_emmc_c_clk0_sel. >> >> [1] >> https://lkml.kernel.org/r/1531133549-25806-2-git-send-email-jian.hu@amlogic.com >> [2] >> https://lkml.kernel.org/r/1531728707-192230-2-git-send-email-jian.hu@amlogic.com >> [3]https://lkml.kernel.org/r/20180717095617.12240-1-jbrunet@baylibre.com >> [4] >> https://lkml.kernel.org/r/1533890858-113020-1-git-send-email-jian.hu@amlogic.com >> >> Jian Hu (2): >> dt-bindings: clk: meson-g12a: Add G12A EE Clock Bindings >> clk: meson-g12a: Add EE Clock controller driver >> >> .../bindings/clock/amlogic,gxbb-clkc.txt | 1 + >> drivers/clk/meson/Kconfig | 10 + >> drivers/clk/meson/Makefile | 1 + >> drivers/clk/meson/g12a.c | 1134 >> ++++++++++++++++++++ >> drivers/clk/meson/g12a.h | 128 +++ >> include/dt-bindings/clock/g12a-clkc.h | 93 ++ >> 6 files changed, 1367 insertions(+) >> create mode 100644 drivers/clk/meson/g12a.c >> create mode 100644 drivers/clk/meson/g12a.h >> create mode 100644 include/dt-bindings/clock/g12a-clkc.h >> > > > . >
