I tried to rework it a bit to make it a bit more tolerable. I needed to change a bit the APIs and consequently adapt the only user we have, that is the nvmem/efuses driver. To not break bisectability I added one single commit to change both the drivers. The remaining commits are cosmetic and DTS/docs fixes. Changelog: - Changed patches order to not break bisect - Removed non-functional changes (PATCH 1/5) of the nvmem driver - Fix gxbb/gxl DTS Carlo Caione (4): firmware: meson_sm: Mark chip struct as static const nvmem: meson-efuse: bindings: Add secure-monitor phandle arm64: dts: meson: Link nvmem and secure-monitor nodes firmware: meson_sm: Rework driver as a proper platform driver .../bindings/nvmem/amlogic-efuse.txt | 6 ++ arch/arm64/boot/dts/amlogic/meson-axg.dtsi | 1 + arch/arm64/boot/dts/amlogic/meson-g12a.dtsi | 1 + arch/arm64/boot/dts/amlogic/meson-gx.dtsi | 1 + drivers/firmware/meson/meson_sm.c | 96 +++++++++++++------ drivers/nvmem/meson-efuse.c | 24 ++++- include/linux/firmware/meson/meson_sm.h | 15 +-- 7 files changed, 104 insertions(+), 40 deletions(-) -- 2.20.1 _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic
