From 551b62b1e4cb64d3b42da0fbfdcd26a5fcd684be Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 18 Nov 2021 21:33:34 -0600 Subject: [PATCH 01/10] clk: sunxi-ng: Export symbols used by CCU drivers For the individual CCU drivers to be built as modules, the ops structs, helper functions, and callback registration functions must be exported. These symbols are intended for use only by the adjacent CCU drivers, so export them into the SUNXI_CCU namespace. of_sunxi_ccu_probe is not exported because it is only used by built-in OF clock providers.

These CCU drivers are relatively large; 32-bit drivers have 30-50k of data each, while the 64-bit ones are 50-75k due to the increased pointer overhead. About half of that data comes from relocations. Let's allow the user to build these drivers as modules so only the necessary data is loaded. As a first step, convert the CCUs that are already platform drivers. When the drivers are built as modules, normally the file name becomes the module name. However, the current file names are inconsistent with the - name used everywhere else: the devicetree bindings, the platform driver names, and the Kconfig symbols. Use Makfile logic to rename the modules so they follow the usual pattern.

Thu, 18 Nov 2021 21:33:36 -0600 Subject: [PATCH 03/10] clk: sunxi-ng: Convert early providers to platform drivers The PRCM CCU drivers depend on clocks provided by other CCU drivers. For example, the sun8i-r-ccu driver uses the "pll-periph" clock provided by the SoC's main CCU. However, sun8i-r-ccu is an early OF clock provider, and many of the main CCUs (e.g. sun50i-a64-ccu) use platform drivers. This means that the consumer clocks will be orphaned until the supplier driver is bound. This can be avoided by converting the remaining CCUs to use platform drivers. Then fw_devlink will ensure the drivers are bound in the optimal order. The sun5i CCU is the only one which actually needs to be an early clock provider, because it provides the clock for the system timer. That one is left alone.

For example, a generic arm64 kernel sees the following improvement when building the CCU core and drivers as modules: before: text data bss dec hex filename 13882360 5251670 360800 19494830 12977ae vmlinux after: text data bss dec hex filename 13734787 5086442 360800 19182029 124b1cd vmlinux So the result is a 390KB total reduction in kernel image size. The one early clock provider (sun5i) requires the core to be built in. Now that loading the MMC driver will trigger loading the CCU core, the MMC timing mode functions do not need a compile-time fallback.

From 3317cb17d5da8416e0a0d9fe3c87dc846f3eb953 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 18 Nov 2021 22:35:40 -0600 Subject: [PATCH 06/10] clk: sunxi-ng: div: Add macros using clk_parent_data and clk_hw Referencing parents with clk_hw pointers is more efficient and removes the dependency on global clock names. clk_parent_data is needed when some parent clocks are provided from another driver. Add macros for declaring dividers that take advantage of these.
