Since the Armbian sources refer to linux 4.19.76 as being linux-mainline, all the patches from linux-4.19 were moved to linux-mainline_4.19 and the linux_4.19.76 recipes was named accordingly. This patch makes 4.19.76 as default version for linux Signed-off-by: Vicentiu Galanopulo <vicentiu@balena.io>

Subject: [PATCH 091/146] clk: sunxi-ng: a64: Add minimal rate for video PLLs
|
|
|
|
According to documentation and experience with other similar SoCs, video
|
|
PLLs don't work stable if their output frequency is set below 192 MHz.
|
|
|
|
Because of that, set minimal rate to both A64 video PLLs to 192 MHz.
