This patch series aims to add several features of the dw-mipi-dsi phy driver that are missing or need to be updated. First patch update a PM macro. Second patch adds runtime PM functionality to the driver. Third patch adds a clock provider generated by the PHY itself. As explained in the commit log of the second patch, a clock declaration is missing. Since this clock is parent of 'dsi_k', it leads to an orphan clock. Most importantly this patch is an anticipation for future versions of the DSI PHY, and its inclusion within the display subsystem and the DRM framework. Last patch fixes a corner effect introduced previously. Since 'dsi' and 'dsi_k' are gated by the same bit on the same register, both reference work as peripheral clock in the device-tree. --- Changes in v3: - Fix smatch warning (disable dsi->pclk when clk_register fails) Changes in v2: - Added patch 1/4 to use SYSTEM_SLEEP_PM_OPS instead of old macro and removed __maybe_used for accordingly - Changed SET_RUNTIME_PM_OPS to RUNTIME_PM_OPS Raphael Gallais-Pou (3): drm/stm: dsi: use new SYSTEM_SLEEP_PM_OPS() macro drm/stm: dsi: expose DSI PHY internal clock arm: dts: st: fix DSI peripheral clock on stm32mp15 boards Yannick Fertre (1): drm/stm: dsi: add pm runtime ops arch/arm/boot/dts/st/stm32mp157.dtsi | 2 +- arch/arm/boot/dts/st/stm32mp157a-dk1-scmi.dts | 2 +- arch/arm/boot/dts/st/stm32mp157c-dk2-scmi.dts | 2 +- arch/arm/boot/dts/st/stm32mp157c-ed1-scmi.dts | 2 +- arch/arm/boot/dts/st/stm32mp157c-ev1-scmi.dts | 2 +- drivers/gpu/drm/stm/dw_mipi_dsi-stm.c | 279 +++++++++++++++--- 6 files changed, 243 insertions(+), 46 deletions(-) -- 2.25.1
