Hello,
This patch series adds support for the MEDIA_BLK_CTRL of the i.MX8MP to
the imx8m-blk-ctrl driver, and integrates it in the i.MX8MP device tree.
The patches depend on v2 of the series "soc: imx: gpcv2: add PGC
control register indirection" from Lucas Stach [1]. For testing
convenience, a branch that includes the dependency, based on v5.17, is
available at [2].
The series starts with DT bindings (1/4) and driver support (2/4),
followed by addition of the MEDIAMIX power domains to the GPC DT node
(3/4) and finally the new DT node for the MEDIA_BLK_CTRL.
Changes since v1 are listed in changelogs in the individual patches.
The patches have been tested with with ISI on the i.MX8MP. The ISI
driver is still under development [3], and will be posted in the not too
distant future.

The names come from the reference manual, at least the ones for the second instance. We have, for instance, SFT_EN_MIPI_CSI_PCLK_RESETN and SFT_EN_MIPI_CSI2_PCLK_RESETN. Same for DSI and LCDIF, there's DSI and DSI2, and LCDIF and LCDIF2. The "1" suffix has been added for clarity. This is a bit bikeshedding territory as I expect the DT node for the media-blk-ctrl to be written once and never be touched again, so if anyone feels strongly about using better names (whatever those better names would be), I don't mind much. I can submit a v3 once a consensus emerges. -- Regards, Laurent Pinchart _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 13+ messages in thread

It's not handled by the gpcv2 driver, but the blk-ctrl driver. The blk- ctrl driver handles the sequencing requirements when powering up/down the "bus" domain, in that case the mediamix domain. In fact there must not be any direct connection between the domains in the GPC DT description as that would cause the requirements for clock and reset propagation to be violated.
