From: Benoît Monin Date: Mon, 16 Mar 2026 15:25:46 +0000 (+0100) Subject: clk: eyeq: Add Mobileye EyeQ6Lplus OLB X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4eb9ed3933e541ed96416608033620f64eea39f5;p=thirdparty%2Fkernel%2Flinux.git clk: eyeq: Add Mobileye EyeQ6Lplus OLB Declare the PLLs and fixed factors found in the EyeQ6Lplus OLB as part of the match data for the "mobileye,eyeq6lplus-olb" compatible. The PLL and fixed factor of the CPU are registered in early init as they are required during the boot by the GIC timer. Also select clk-eyeq for all EYEQ SoCs instead of listing each one individually, as it is needed by all Mobileye EyeQ SoC.
