Subject: [PATCH v8 0/3] media: imx: add support for imx8mq MIPI RX
Date: Fri, 23 Jul 2021 12:12:14 +0200	[thread overview]
Message-ID: <> (raw)


This patch series adds a driver for the i.MX8MQ CSI MIPI receiver / controller.

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,


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

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

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

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

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"

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()
