Thanks for your feedback! Perhaps it would be the best to simply drop the submission to stable kernels... Believe it or not, :) I spent a fair amount of time deliberating over the submission to stable, but now I think it's simply better to omit that and not increase the amount of patches that go into stable unnecessary. Would you like me to send the v2 with no Cc to stable, or would you prefer to drop that line yourself? >> Signed-off-by: Dragan Simic >> --- >> arch/arm64/boot/dts/rockchip/rk356x.dtsi | 24 >> ++++++++++++------------ >> 1 file changed, 12 insertions(+), 12 deletions(-) >> >> diff --git a/arch/arm64/boot/dts/rockchip/rk356x.dtsi >> b/arch/arm64/boot/dts/rockchip/rk356x.dtsi >> index 4690be841a1c..9f7136e5d553 100644 >> --- a/arch/arm64/boot/dts/rockchip/rk356x.dtsi >> +++ b/arch/arm64/boot/dts/rockchip/rk356x.dtsi >> @@ -113,19 +113,19 @@ cpu3: cpu@300 { >> d-cache-sets = <128>; >> next-level-cache = <&l3_cache>; >> }; >> - }; >> >> - /* >> - * There are no private per-core L2 caches, but only the >> - * L3 cache that appears to the CPU cores as L2 caches >> - */ >> - l3_cache: l3-cache { >> - compatible = "cache"; >> - cache-level = <2>; >> - cache-unified; >> - cache-size = <0x80000>; >> - cache-line-size = <64>; >> - cache-sets = <512>; >> + /* >> + * There are no private per-core L2 caches, but only the >> + * L3 cache that appears to the CPU cores as L2 caches >> + */ >> + l3_cache: l3-cache { >> + compatible = "cache"; >> + cache-level = <2>; >> + cache-unified; >> + cache-size = <0x80000>; >> + cache-line-size = <64>; >> + cache-sets = <512>; >> + }; >> }; >> >> cpu0_opp_table: opp-table-0 { >> > > > > > > _______________________________________________ > Linux-rockchip mailing list > Linux-rockchip@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-rockchip _______________________________________________ Linux-rockchip mailing list Linux-rockchip@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-rockchip
