clk: sunxi-ng: Allow the CCU core to be built as a module Like the individual CCU drivers, it can be beneficial for memory consumption of cross-platform configurations to only load the CCU core on the relevant platform. 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.

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.

Also, the MMC2 module clock supports switching to a "new timing" mode. This mode divides the clock output by half, and disables the CCU based clock delays. The MMC controller must be configure to the same mode, and then use its internal clock delays. This driver does not support runtime switching of the timing modes. Instead, the new timing mode is enforced at probe time. Consumers can check which mode is active by trying to get the current phase delay of the MMC2 phase clocks, which will return -ENOTSUPP if the new timing mode is active.

config SUN9I_A80_CCU
clk: sunxi-ng: Allow drivers to be built as modules While it is useful to build all of the CCU drivers at once, only 1-3 of them will be loaded at a time, or possibly none of them if the kernel is booted on a non-sunxi platform. 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 <platform>-<peripheral> 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.

tristate "Support for the Allwinner A80 CCU"
clk: sunxi-ng: Add A80 CCU Add support for the main clock unit found in the A80. Some clocks were not documented in the released user manual, but were found in the official kernel from Allwinner. These include controls for the I2S, SPDIF, SATA, and eDP blocks. Note that on the A80, some subsystems have separate clock controllers downstream of the main clock unit. These include the MMC, USB, and display engine subsystems.

config SUN8I_R_CCU
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.
