Message-ID: <20250108005854.2973184-1-sboyd@kernel.org> Date: Tue, 7 Jan 2025 16:58:45 -0800 From: Stephen Boyd <sboyd@...nel.org> To: Michael Turquette <mturquette@...libre.com>, Stephen Boyd <sboyd@...nel.org> Cc: linux-kernel@...r.kernel.org, linux-clk@...r.kernel.org, patches@...ts.linux.dev Subject: [PATCH 0/4] clk: Move debugfs to a loadable kernel module This series moves as much of the debugfs code as possible from the core clk framework file clk.c into a loadable kernel module. The goal is to move the debugfs code out of the primary vmlinux and allow users to decide if they want to load the debugging logic at all. To get there, we make the debugfs code use struct clk_hw and then add a bunch of helpers to interrogate the clk_hw enough to satisfy the use-cases we have in debugfs today. Finally we move the code from clk.c to clk-debug.c almost wholesale, except for some tree walking logic and functions to interrogate a struct clk_hw or install a function pointer to call when a clk is registered. I'll probably wait to merge this until after we're able to limit the exporting of kernel symbols to particular modules, because I'm not super excited with exporting internal clk details to any module. For now, I've put the symbols that are newly introduced for debugfs into the "clk-debug" namespace.
