From 93dd2f7211db6607184adadb488582e01fd5c29b Mon Sep 17 00:00:00 2001 From: Ram Chandra Jangir Date: Fri, 4 May 2018 21:57:33 +0530 Subject: ipq806x: add kernel 4.14 support - Rebased the patches for 4.14 - Dropped spi-qup and 0027, 0028, 0029 clk patches since it's already included in upstream. Tested on IPQ AP148 Board: 1) NOR boot and NAND boot 2) Tested USB and PCIe interfaces 3) WDOG test 4) cpu frequency scaling 5) ethernet, 2G and 5G WiFi 6) ubi sysupgrade Signed-off-by: Ram Chandra Jangir Tested-by: Stefan Lippers-Hollmann --- ...0046-cpufreq-qcom-independent-core-clocks.patch | 65 ++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 target/linux/ipq806x/patches-4.14/0046-cpufreq-qcom-independent-core-clocks.patch (limited to 'target/linux/ipq806x/patches-4.14/0046-cpufreq-qcom-independent-core-clocks.patch') diff --git a/target/linux/ipq806x/patches-4.14/0046-cpufreq-qcom-independent-core-clocks.patch b/target/linux/ipq806x/patches-4.14/0046-cpufreq-qcom-independent-core-clocks.patch new file mode 100644 index 0000000..d7211e1 --- /dev/null +++ b/target/linux/ipq806x/patches-4.14/0046-cpufreq-qcom-independent-core-clocks.patch @@ -0,0 +1,65 @@ +From patchwork Fri Dec 8 09:42:30 2017 +Content-Type: text/plain; charset="utf-8" +MIME-Version: 1.0 +Content-Transfer-Encoding: 7bit +Subject: [v4,12/12] cpufreq: dt: Reintroduce independent_clocks platform data +From: Sricharan R +X-Patchwork-Id: 10102073 +Message-Id: <1512726150-7204-13-git-send-email-sricharan@codeaurora.org> +To: mturquette@baylibre.com, sboyd@codeaurora.org, + devicetree@vger.kernel.org, linux-pm@vger.kernel.org, + linux-arm-msm@vger.kernel.org, linux-kernel@vger.kernel.org, + viresh.kumar@linaro.org, linux-arm-kernel@lists.infradead.org +Cc: sricharan@codeaurora.org +Date: Fri, 8 Dec 2017 15:12:30 +0530 + +The Platform data was removed earlier by, +'commit eb96924acddc ("cpufreq: dt: Kill platform-data")' +since there were no users at that time. +Now this is required when the each of the cpu clocks +can be scaled independently, which is the case +for krait cores.
