Some of these GPRs are used to control some clocks, other some resets, others some very specific function that does not fit into clocks or resets. Since the clocks are registered using the i.MX clock subsystem API, the driver is placed into the clock subsystem, but it also registers the resets. For the other functionalities that other GPRs might have, the syscon is used. Changes since v2: * Made the naming consistent with the RM: BLK_CTL (not BLK_CTRL) * fixed the reset set procedure as discussed with Philipp Zabel * removed the patch that includes the imx8mp-reset header in dtsi as there is no user yet. * added i.MX8MP specific blk_ctl driver as suggested by Aisheng Dong Abel Vesa (14): dt-bindings: clocks: imx8mp: Rename audiomix ids clocks to audio_blk_ctl dt-bindings: reset: imx8mp: Add audio blk_ctl reset IDs dt-bindings: clock: imx8mp: Add ids for the audio shared gate dt-bindings: clock: imx8mp: Add media blk_ctl clock IDs dt-bindings: reset: imx8mp: Add media blk_ctl reset IDs dt-bindings: clock: imx8mp: Add hdmi blk_ctl clock IDs dt-bindings: reset: imx8mp: Add hdmi blk_ctl reset IDs clk: imx8mp: Add audio shared gate Documentation: bindings: clk: Add bindings for i.MX BLK_CTL clk: imx: Add generic blk-ctl driver clk: imx: Add blk-ctl driver for i.MX8MP arm64: dts: imx8mp: Add audio_blk_ctl node arm64: dts: imx8mp: Add media_blk_ctl node arm64: dts: imx8mp: Add hdmi_blk_ctl node .../devicetree/bindings/clock/fsl,imx-blk-ctl.yaml | 60 ++++ arch/arm64/boot/dts/freescale/imx8mp.dtsi | 37 +++ drivers/clk/imx/Makefile | 2 +- drivers/clk/imx/clk-blk-ctl-imx8mp.c | 313 +++++++++++++++++++++ drivers/clk/imx/clk-blk-ctl.c | 297 +++++++++++++++++++ drivers/clk/imx/clk-blk-ctl.h | 80 ++++++ drivers/clk/imx/clk-imx8mp.c | 12 +- include/dt-bindings/clock/imx8mp-clock.h | 200 +++++++++---- include/dt-bindings/reset/imx8mp-reset.h | 45 +++ 9 files changed, 983 insertions(+), 63 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/fsl,imx-blk-ctl.yaml create mode 100644 drivers/clk/imx/clk-blk-ctl-imx8mp.c create mode 100644 drivers/clk/imx/clk-blk-ctl.c create mode 100644 drivers/clk/imx/clk-blk-ctl.h -- 2.7.4
