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

Posted by Icenowy Zheng 4 months, 1 week ago

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].
