From: Jerome Brunet Date: Mon, 13 May 2019 12:31:14 +0000 (+0200) Subject: clk: meson: eeclk: add init regs X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=19a18d42bf557b8420a55e0fce7be5aec9f8ef8c;p=linux.git clk: meson: eeclk: add init regs Like the PLL and MPLL, the controller may require some magic setting to be applied on startup. This is needed when the initial setting is not applied by the boot ROM. The controller need to do it when the setting applies to several clock, like all the MPLLs in the case of g12a.
