| Message-ID | <tI4dH-1LO-15@gated-at.bofh.it> |
These series of patches amend some assigned-clocks and add cpu opp table for rk322x SoCs. the following patches on patchwork are required for this change. https://patchwork.kernel.org/patch/9627639/ https://patchwork.kernel.org/patch/9703945/ https://patchwork.kernel.org/patch/9703939/ https://patchwork.kernel.org/patch/9707517/ Changes from v1: - Updated the 'Signed-off-by' tag with original authors' email id. - Updated the 'Acked-by' tag from Viresh Kumar <viresh.kumar@linaro.org>.
