Hello, This builds on previous EyeQ5 system-controller revisions [0] and adds EyeQ6L + EyeQ6H support. Pinctrl is not affected because it is not handled in the same manner on those new platforms; it will be dealt with with pinctrl-single. Only clk and reset expand to support those new platform. Changes in drivers are pretty massive, which explains why I started a new revision count. EyeQ6H is particular in that it has not one but seven OLB instances. All seven host a (different) clock controller. Three host a reset controller. Patches are targeting MIPS, clk, reset and pinctrl trees independently. - dt-bindings: soc: mobileye: add EyeQ5 OLB system controller - MIPS: mobileye: eyeq5: add OLB syscon node - MIPS: mobileye: eyeq5: use OLB clocks controller node - MIPS: mobileye: eyeq5: add OLB reset controller node - MIPS: mobileye: eyeq5: add pinctrl node & pinmux function nodes Patches have no dependencies on this series. All required devicetrees and bindings got in the last release. Bindings changes below are only related to EyeQ6L/EyeQ6H. - dt-bindings: clock: mobileye,eyeq5-clk: add EyeQ6L and EyeQ6H - clk: divider: Introduce CLK_DIVIDER_EVEN_INTEGERS flag - clk: eyeq: add driver Clocks on all three platforms are rather similar. We have a bunch of PLLs children to the main crystal, some being required early (at of_clk_init(), before platform bus init). We have a few divider clocks in some instances. A custom clk-divider flag is introduced for the divisor because one clk would have a 256 entries table otherwise. Compatible match data stores it all, nothing is declared in DT. Match data has three arrays for the three types of clocks: early PLLs, standard PLLs and divider clks. - dt-bindings: reset: mobileye,eyeq5-reset: add EyeQ6L and EyeQ6H - reset: eyeq: add platform driver Resets on all three platforms are rather similar. We therefore declare reset domain types and assign compatibles to an array of domains, with types and valid masks associated. The rest is pretty similar to previous code. EyeQ6H west and east OLB each host an instance of the same compat. - pinctrl: eyeq5: add platform driver Not affected by EyeQ6L/EyeQ6H additions. It has not changed.
