Merge tag 'sunxi-clk-for-5.6' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into clk-allwinner
Pull Allwinner clk driver updates from Maxime Ripard:
Our usual set of patches for sunxi, with a bunch of them required to
enable the MBUS controller, and two patches to enable cpufreq on the
A64.
* tag 'sunxi-clk-for-5.6' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux:
clk: sunxi: a23/a33: Export the MIPI PLL
clk: sunxi: a31: Export the MIPI PLL
clk: sunxi-ng: a64: export CLK_CPUX clock for DVFS
clk: sunxi-ng: add mux and pll notifiers for A64 CPU clock
clk: sunxi-ng: r40: Export MBUS clock
clk: sunxi: use of_device_get_match_data
