From: Matthias Brugger <mbrug...@suse.com> Jasper send this series some month ago. As there was no reaction from his side, I'll do a friendly take-over. I tested the patches on my Helios X20 boards and they fix the issue. I didn't add a Tested-by tag as I added my Signed-off-by.
Changes since v3: - add comments explaining why the clock muxer and gates are marked as critical Changes since v2 (https://patchwork.kernel.org/patch/10686759/): - axi_sel is not needed, drop CLK_IS_CRITICAL for it. - update commit message - add Acked-by from Mars Changes since v1: - add a fixes tag. --- Currently, DRAM-related clocks and the axi_sel MUX are not marked with CLK_IS_CRITICAL for MT6797. This causes memory corruption when the system is booted without clk_ignore_unused. This patchset 1. Makes it possible to mark outputs of MUXes as critical by introducing a new macro, MUX_FLAGS, 2. Makes it possible to mark gates as critical by adding flags to mtk_gate, and 3. Marks axi_sel, ddrphycfg_sel, infra_dramc_f26m and infra_dramc_b_f26m as critical. The addition of flags to mtk_gate also exists in the patch series "Add basic and clock support for Mediatek MT8183 SoC" [1]. The type of flags is unsigned int in that series, but the real type is unsigned long, so my patch differs from that patch.
