* Use latest ODROID-N2+ patches (partial #929) Use the queued patches (and fixes) for upstream ODROID-N2+ support. This uses the clock settings from meson-g12b-a311d.dtsi running the CPUs at the following clocks: - 4xA73@2.2GHz - 2xA53@1.8GHz * Actually fix CDC ACM error recovery path (#921) Remove the revert of the cool-down patch and add the actual fix for the CDC ACM error recovery path.

Subject: [PATCH 13/14] clk: meson: g12a: mark fclk_div2 as critical
|
|
|
|
On Amlogic Meson G12b platform, similar to fclk_div3, the fclk_div2
|
|
seems to be necessary for the system to operate correctly as well.
|
|
|
|
Typically, the clock also gets chosen by the eMMC peripheral. This
|
|
probably masked the problem so far. However, when booting from a SD
|
|
card the clock seems to get disabled which leads to a system freeze.
|
|
|
|
Let's mark this clock as critical, fixing boot from SD card on G12b
|
|
platforms.
