It includes the driver, the dt-bindings and the DT addition to the SoC dtsi. I test it using libcamera. Thanks to Laurent who helped a lot. I'm happy for any feedback, martin revision history ---------------- v8: (thank you Laurent) * calculate hs_settle for any clk rate and mode * add reviewed-by tag v7: (thank you Laurent and Rob) * fix the binding example (include the reset driver) * use pm_runtime_resume_and_get() * fix some logic in init_cfg() * add some useful code comments and fix minor bits found by Laurent in v6 https://lore.kernel.org/linux-media/20210716102244.581182-1-martin.kepplinger@puri.sm/T/#t v6: (thank you Laurent and Rob) * add reviewed-by tag to binding * statically allocate clk_bulk_data * fix how the hs_settle value is applied * remove s_power calls * remove the link_setup() callback implementation and make the link immutable * more cleanups according to Laurents' review from v5 https://lore.kernel.org/linux-media/20210714111931.324485-1-martin.kepplinger@puri.sm/ v5: (thank you Laurent) * fix reset usage by using the already supported reset controller driver * remove clko2 (totally unrelated clock / had been included by accident) * rename pxl clock to ui https://lore.kernel.org/linux-media/20210618095753.114557-1-martin.kepplinger@puri.sm/ v4: (thank you Rob and Marco) * create fsl,mipi-phy-gpr custom dt property instead of confusing "phy" * add imx8mq-specific compatibile to imx8mq.dtsi for future use https://lore.kernel.org/linux-media/20210614121522.2944593-1-martin.kepplinger@puri.sm/ v3: (thank you, Rob and Laurent) among minor other things according to v2 review, changes include: * better describe the clocks * rename DT property "phy-reset" to "reset" and "phy-gpr" to "phy" https://lore.kernel.org/linux-media/20210608104128.1616028-1-martin.kepplinger@puri.sm/T/#t v2: (thank you, Dan and Guido) among fixes according to v1 reviews, changes include: * remove status property from dt-bindings example * define a few bits in order to have less magic values * use "imx8mq_mipi_csi_" as local function prefix * read DT properties only during probe() * remove dead code (log_status) * add imx8mq_mipi_csi_release_icc() * fix imx8mq_mipi_csi_init_icc() https://lore.kernel.org/linux-media/20210531112326.90094-1-martin.kepplinger@puri.sm/ v1: https://lore.kernel.org/linux-media/20210527075407.3180744-1-martin.kepplinger@puri.sm/T/#t Martin Kepplinger (3): dt-bindings: media: document the nxp,imx8mq-mipi-csi2 receiver phy and controller media: imx: add a driver for i.MX8MQ mipi csi rx phy and controller arm64: dts: imx8mq: add mipi csi phy and csi bridge descriptions .../bindings/media/nxp,imx8mq-mipi-csi2.yaml | 174 ++++ arch/arm64/boot/dts/freescale/imx8mq.dtsi | 104 ++ drivers/staging/media/imx/Makefile | 1 + drivers/staging/media/imx/imx8mq-mipi-csi2.c | 979 ++++++++++++++++++ 4 files changed, 1258 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/nxp,imx8mq-mipi-csi2.yaml create mode 100644 drivers/staging/media/imx/imx8mq-mipi-csi2.c
