Subject: [PATCH 01/82] clk: sunxi-ng: Set maximum M = 1 for H3 pll-cpux clock
|
|
|
|
When using M factor greater than 1 system is experiencing
|
|
occasional lockups.
|
|
|
|
This change was verified to fix lockups with PLL stress
|
|
tester available at https://github.com/megous/h3-firmware.
|
|
|
|
Note that M factor must not be used outside the kernel
|
|
either, so for example u-boot needs a similar patch.
