Hi Stephen, This series is made against clk-next. Due to newly added clk-imx7ulp and clk-imx8mq in clk-next, you may meet apply failure if apply against clk-master branch. So If you need me to re-generate a patch series against clk-master, Please let me know. But that may still get an error when merger the Series Into clk-next, I guess. Regards Dong Aisheng

Note: It depends on SCU driver which has already been merged by Shawn. So this patch series could go through Shawn's tree as well. ChangeLog: v9->v10: * a small clean up of PATCH 2 remove ccm_ipc_handle from headfile as no other users need it now and move imx_clk_scu_init() implementation into driver accordingly. * a typo fix of Patch 10 v8->v9: * add __le32 and __le16 for SCU message structure members as it's little endian * use readl_relaxed() as it does not need insert barrier * a small code logic improvement suggested by Stephen v7->v8: * add more kernel doc for lpcg and scu clock structures * remove one unneccessry reg checking v6->v7: * use struct_size() * remove MODULE_ macros * add more kernel docs/code comments * other small improvements * update reviewed-by tags * add the missing PATCH 1 in V6 v5->v6: * simply the driver a lot by re-orgnizing the driver into a few clock types: scu clock (merge scu divider/gate/mux) and scu gpr lock which accessing is through SCU protocol and LPCG clock which is directly accessible by CPU. * LPCG clock is separate from SCU clock, gpr clock is still not used and will be added later. * remove old year license as the code is totally rewritten * scu mux support will be added later as it's also still not used. v4->v5: Address all Stephen and Sascha's review comments, see details in each patch v3->v4: * scu headfile path update * no functionality change v2->v3: * structures/enums name update with imx_sc prefix * no functionality change v1->v2: * structure and enums name update * api usage update due to api change * no functionality change Dong Aisheng (7): clk: imx: add configuration option for mmio clks clk: imx: add scu clock common part dt-bindings: clock: imx8qxp: add SCU clock IDs clk: imx: add imx8qxp clk driver dt-bindings: clock: add imx8qxp lpcg clock binding clk: imx: add lpcg clock support clk: imx: add imx8qxp lpcg driver .../devicetree/bindings/clock/imx8qxp-lpcg.txt | 51 ++++ arch/arm/mach-imx/Kconfig | 11 + drivers/clk/Kconfig | 1 + drivers/clk/imx/Kconfig | 9 + drivers/clk/imx/Makefile | 8 +- drivers/clk/imx/clk-imx8qxp-lpcg.c | 216 +++++++++++++++ drivers/clk/imx/clk-imx8qxp-lpcg.h | 102 ++++++++ drivers/clk/imx/clk-imx8qxp.c | 153 +++++++++++ drivers/clk/imx/clk-lpcg-scu.c | 114 ++++++++ drivers/clk/imx/clk-scu.c | 270 +++++++++++++++++++ drivers/clk/imx/clk-scu.h | 18 ++ include/dt-bindings/clock/imx8qxp-clock.h | 289 +++++++++++++++++++++ 12 files changed, 1241 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/clock/imx8qxp-lpcg.txt create mode 100644 drivers/clk/imx/Kconfig create mode 100644 drivers/clk/imx/clk-imx8qxp-lpcg.c create mode 100644 drivers/clk/imx/clk-imx8qxp-lpcg.h create mode 100644 drivers/clk/imx/clk-imx8qxp.c create mode 100644 drivers/clk/imx/clk-lpcg-scu.c create mode 100644 drivers/clk/imx/clk-scu.c create mode 100644 drivers/clk/imx/clk-scu.h create mode 100644 include/dt-bindings/clock/imx8qxp-clock.h -- 2.7.4
