Hello everyone This series adds in the OPPs for the Cortex-A53s on the AM62Ax and AM62Px SoC families along with the defining the WKUP_MMR0_WKUP0_CTRL_MMR0_JTAG_USER_ID which we can use to properly limit the OPPs available for that variant. Moreover, it also adds a driver cleanup where we can finally get rid of the rev_offsets and zero the efuse_offsets as they are now taken from socinfo and DT efuse node register respectively. This series has been tested on all devices that it affects and has been confirmed to cause no known regressions. It also tries to fix the AM625 devicetree syscon nodes, while also ensuring that within the driver we don't end up breaking the older DT. Prints a warning incase older DT is detected. Test logs: https://gist.github.com/DhruvaG2000/63f5e28636d52787488f776e5bf39498 Changelog: --- Changes in v7: - Based on Andrew's comments, re-worded the comment in the driver and also used a different approach for finding old DT, this way it's less error prone than how things were done in v6. - Added a warning print when using old DT: https://gist.github.com/DhruvaG2000/63f5e28636d52787488f776e5bf39498#file-am62x-cpufreq-test-log-old-dt-txt-L220 - Link to v6: https://lore.kernel.org/r/20240925-ti-cpufreq-fixes-v5-v6-0-46f41a903e01@xxxxxx Changes in v6: - Ensure backward compaibility for AM625 DT, by handling the old DT in a special way inside the cpufreq driver itself. This is based on feedback from Nishanth where we are not okay to break the old DT working with new kernels. - Link to v5: https://lore.kernel.org/r/20240924-ti-cpufreq-fixes-v5-v5-0-cbe16b9ddb1b@xxxxxx Changes in v5: - Based on Andrew's review on v4 of "arm64: dts: ti: k3-am62: use opp_efuse_table for opp-table syscon", - s/syscon@43000000/bus@43000000/ - Drop the "reg = <>;" line - Link to v4: https://lore.kernel.org/all/20240919082809.174589-1-d-gole@xxxxxx/ Changes in v4: - Add 2 more patches to this series: - Driver cleanup as described above. - AM625 DT fixups (Link to v1 of that patch: https://lore.kernel.org/all/20240902093222.2828345-2-d-gole@xxxxxx/) - Link to v3: https://lore.kernel.org/all/20240826-opp-v3-0-0934f8309e13@xxxxxx/ Changes in v3: - Miscellaneous spelling fixes in commit body - Link to v2: https://lore.kernel.org/r/20240823-opp-v2-0-e2f67b37c299@xxxxxx Changes in v2: - Expanded on commit descriptions - Split board file and SoC fdt changes into different patches - Link to v1: https://lore.kernel.org/r/20240809-opp-v1-0-fea8efeaf963@xxxxxx --- Bryan Brattlof (4): arm64: dts: ti: k3-am62a: add opp frequencies arm64: dts: ti: k3-am62a7-sk: add 1.4ghz opp entry arm64: dts: ti: k3-am62p: add opp frequencies arm64: dts: ti: k3-am62p5-sk: add 1.4ghz opp entry Dhruva Gole (2): arm64: dts: ti: k3-am62: use opp_efuse_table for opp-table syscon cpufreq: ti-cpufreq: Update efuse/rev offsets in AM62 family arch/arm64/boot/dts/ti/k3-am62-wakeup.dtsi | 7 ++- arch/arm64/boot/dts/ti/k3-am625.dtsi | 2 +- arch/arm64/boot/dts/ti/k3-am62a-wakeup.dtsi | 5 ++ arch/arm64/boot/dts/ti/k3-am62a7-sk.dts | 9 ++++ arch/arm64/boot/dts/ti/k3-am62a7.dtsi | 51 +++++++++++++++++++ .../dts/ti/k3-am62p-j722s-common-wakeup.dtsi | 5 ++ arch/arm64/boot/dts/ti/k3-am62p5-sk.dts | 9 ++++ arch/arm64/boot/dts/ti/k3-am62p5.dtsi | 47 +++++++++++++++++ drivers/cpufreq/ti-cpufreq.c | 5 +- 9 files changed, 134 insertions(+), 6 deletions(-) base-commit: 55bcd2e0d04c1171d382badef1def1fd04ef66c5 -- 2.34.1 --- Bryan Brattlof (4): arm64: dts: ti: k3-am62a: add opp frequencies arm64: dts: ti: k3-am62a7-sk: add 1.4ghz opp entry arm64: dts: ti: k3-am62p: add opp frequencies arm64: dts: ti: k3-am62p5-sk: add 1.4ghz opp entry Dhruva Gole (2): arm64: dts: ti: k3-am62: use opp_efuse_table for opp-table syscon cpufreq: ti-cpufreq: Update efuse/rev offsets in AM62 family arch/arm64/boot/dts/ti/k3-am62-wakeup.dtsi | 10 +++-- arch/arm64/boot/dts/ti/k3-am625.dtsi | 2 +- arch/arm64/boot/dts/ti/k3-am62a-wakeup.dtsi | 5 +++ arch/arm64/boot/dts/ti/k3-am62a7-sk.dts | 9 ++++ arch/arm64/boot/dts/ti/k3-am62a7.dtsi | 51 ++++++++++++++++++++++ .../boot/dts/ti/k3-am62p-j722s-common-wakeup.dtsi | 5 +++ arch/arm64/boot/dts/ti/k3-am62p5-sk.dts | 9 ++++ arch/arm64/boot/dts/ti/k3-am62p5.dtsi | 47 ++++++++++++++++++++ drivers/cpufreq/ti-cpufreq.c | 24 +++++++--- 9 files changed, 152 insertions(+), 10 deletions(-) --- base-commit: 55bcd2e0d04c1171d382badef1def1fd04ef66c5 change-id: 20240924-ti-cpufreq-fixes-v5-dbb3e5056b6c Best regards, -- Dhruva Gole <d-gole@xxxxxx>
