This is inevitable since our TI port is dying because no one is maintaining it. Maybe some hackish way would be possible for a short time but the real solution is to do a proper clock implementation if someone care about those SoCs. Fixed now that we have clock drivers. |
Head r358906 will boot but several drivers fails in ti_hwmods_get_clock() due to removal of ti,hwmods in am33xx-l4.dtsi (r358430). r358906 will work fine with DTS from pre r358430. Is it possible to update struct hwmod ti_hwmods[] { ... } to map properties from parent sysc, for example clocks? gpio0_target: target-module@7000 { /* 0x44e07000, ap 14 20.0 */ compatible = "ti,sysc-omap2", "ti,sysc"; ... clocks = <&l4_wkup_clkctrl AM3_L4_WKUP_GPIO1_CLKCTRL 0>, <&l4_wkup_clkctrl AM3_L4_WKUP_GPIO1_CLKCTRL 18>; ... gpio0: gpio@0 { }; }; target-module@4c000 { /* 0x4804c000, ap 32 36.0 */ compatible = "ti,sysc-omap2", "ti,sysc"; ... clocks = <&l4ls_clkctrl AM3_L4LS_GPIO2_CLKCTRL 0>, <&l4ls_clkctrl AM3_L4LS_GPIO2_CLKCTRL 18>; ... gpio1: gpio@0 { .... }; };
