[PATCH v2 0/3] clk: thead: Changes to TH1520 clock driver for disp

[Icenowy Zheng]

This patchset is my changes to the TH1520 clock driver, mainly for
supporting the display controller.

The first two are functionality additions, with the first one adding
support for enabling/disabling PLLs (for DPU PLL) and the second one
adding support for changing DPU dividers.

The 3rd one is to address hang issues met when testing the DPU driver
w/o clk_ignore_unused command line option.

The 4th patch that used to be in v1 is dropped, makes this patchset
purely display-related.

This patchset has a dependency (a 0th one) [1].
