* [PATCH v3 0/3] Reset controller support for i.MX8MQ @ 2018-12-17 2:38 Andrey Smirnov 2018-12-17 2:38 ` [PATCH v3 1/3] reset: imx7: Add plubming to support multiple IP variants Andrey Smirnov ` (2 more replies) 0 siblings, 3 replies; 9+ messages in thread From: Andrey Smirnov @ 2018-12-17 2:38 UTC (permalink / raw) To: linux-kernel Cc: A.s. Dong, Rob Herring, Richard Zhu, linux-arm-kernel, devicetree, Andrey Smirnov, linux-imx, p.zabel, Fabio Estevam, Leonard Crestez, cphealy, l.stach Everyone: This patch contains changes I made in order to add support for i.MX8MQ to reset-imx7.c in order to enable support of PCIE IP block on i.MX8MQ SoCs. NOTE: This patch depens on CONFIG_ARCH_IMX8MQ introduced in [imx8mq] Feedback is welcome! Thanks, Andrey Smirnov Changes since [v2] - Constified "variant" field in struct imx7_src - Moved dt-bindings/reset/imx8mq-reset.h to be a part of the patch documenting DT bindings Changes since [v1] - Series re-written to use a per-variant LUT instead of using a single table - Changed driver to use "imx8mq" insead of "imx8m" to match other drivers and CONFIG_ARCH_IMX8MQ - Updated list of exported i.MX8MQ resets, add missing and remove bogus ones (hopefully nothing is missing this time) [v2] lkml.kernel.org/r/20181128043738.12714-1-andrew.smirnov@gmail.com [v1] lkml.kernel.org/r/20181117181131.9330-2-andrew.smirnov@gmail.com [imx8mq] https://www.spinics.net/lists/arm-kernel/msg687293.html Andrey Smirnov (3): reset: imx7: Add plubming to support multiple IP variants dt-bindings: reset: imx7: Document usage on i.MX8MQ SoCs reset: imx7: Add support for i.MX8MQ IP block variant .../bindings/reset/fsl,imx7-src.txt | 7 +- drivers/reset/Kconfig | 2 +- drivers/reset/reset-imx7.c | 166 ++++++++++++++++-- include/dt-bindings/reset/imx8mq-reset.h | 64 +++++++ 4 files changed, 220 insertions(+), 19 deletions(-) create mode 100644 include/dt-bindings/reset/imx8mq-reset.h -- 2.19.1 _______________________________________________ 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] 9+ messages in thread
