| Series | Basic clock, reset & device tree support for StarFive JH7110 RISC-V SoC | expand |
Emil, I tried messaging you on IRC yesterday, but message probably got lost in the ether :( On Mon, Mar 20, 2023 at 06:37:29PM +0800, Hal Feng wrote: > This patch series adds basic clock, reset & DT support for StarFive > JH7110 SoC. Are you happy with how the series looks now and if so, how do you want to go about getting it applied? To me, what'd seem ideal, is a branch that starts w/ the two binding changes for clock and reset so that that bit can be shared between clock/reset drivers and dts bits. Since, I, at least, am happy with the dts since of things, I've gone and created such a branch with the dt-bindings at the start, followed by the dts bits, and pushed it here: https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux.git/log/?h=riscv-jh7110_initial_dts If you're happy on the driver side of things, do you want to pick those patches up on top of the bindings and send a PR to Stephen? No rush if you're not, still got a fair bit of time til the merge window yada-yada & I won't merge this branch into the riscv-dt for-next one until the bindings are in the clock tree. Thanks, Conor. (I did end up re-creating the first patch on that branch, b4/git am didn't like the maintainers change, so hopefully I've not made a hames of it.) > > You can simply review or test the patches at the link [1]. > > [1]: https://github.com/hal-feng/linux/commits/visionfive2-minimal > > Changes since v5: > - Rebased on v6.3-rc3. > Patch 1: > - Set obj-y for starfive/ in drivers/clk/Makefile. > Patch 2: > - Sorted the StarFive entries alphabetically in MAINTAINERS. > Patch 3: > - Fixed the build error which caused by renaming the header without > changing the users of the header. > Patch 4: > - Fixed the errors reported by checkpatch.pl. > Patch 6: > - Set obj-y for starfive/ in drivers/reset/Makefile. > Patch 13: > - Set the timer clock flags as 0. > > v5: https://lore.kernel.org/all/20230311090733.56918-1-hal.feng@starfivetech.com/ > > Changes since v4: > - Rebased on v6.3-rc1. > - Added two patches to replace SOC_STARFIVE with ARCH_STARFIVE. > - Added Tested-by tag for Tommaso. > Patch 9: > - Set GMAC1 related clocks as optional inputs. > - Dropped PLL clock definitions. > Patch 10: > - Set GMAC0 related clocks and RTC oscillator as optional inputs. > - Sorted the clocks. > Patch 11: > - Replaced SOC_STARFIVE with ARCH_STARFIVE. > - Added macros for PLL clocks and adjusted the code properly to > make it easier to add the PLL clock driver later. > - Updated the clock flags. > Patch 12: > - Built as a module by default. > - Sorted the clocks. > - Updated the clock flags. > Patch 13: > - Replaced "default CLK_STARFIVE_JH7110_SYS" with "default ARCH_STARFIVE". > - Renamed "reset_info" struct to "jh7110_reset_info" and moved its > definition into the driver. > - Put jh7110_sys_info and jh7110_sys_info before the probe(). > Patch 17: > - Dropped "_zicsr" in ISA. > - Sorted the external clocks alphabetically. > - Put the ccache node before the plic node according to their addresses. > - Sorted the clock inputs of the aoncrg node. > Patch 19: > - Replaced SOC_STARFIVE with ARCH_STARFIVE. > - Sorted the nodes alphabetically. > > v4: https://lore.kernel.org/all/20230221024645.127922-1-hal.feng@starfivetech.com/ > > Changes since v3: > - Suggested by Conor, Merged clock & reset series and DT series together > so that they could go via the same tree as the dt-binding headers are > required by both driver & devicetree. > - Rebased on tag v6.2. > > [Clock & reset] > Patch 2: > - Split patch 2 into two.

Since it was off-list: Emil and I spoke about this briefly today at the weekly linux-riscv meeting, the upshot of which is that it is likely to be me, rather than him, sending you a PR as he's pretty busy at the moment. That said, Emil mentioned that he has some doubts as to whether the bindings are correct, and from taking a look - he's right, so there'll likely not be a PR just yet! I'll go leave a comment about that... I've got no real desire to maintain these drivers going forward though, so perhaps Hal, or one of the other StarFive folks, can get themselves set up to send them to you going forwards? Cheers, Conor.

It doesn't really matter as long as I know what's going on.

Probably obvious at this point given the number of outstanding comments on this version, but I'm gonna mark this series as "Changes Requested" on the RISC-V patchwork. I'm not sure what Stephen's cutoff for stuff is, but I'd like to have stuff ready to go to Arnd for -rc6, so you still have some time for another revision I think :) Cheers, Conor.

This patch series adds basic clock, reset & DT support for StarFive JH7110 SoC. You can simply review or test the patches at the link [1]. [1]: https://github.com/hal-feng/linux/commits/visionfive2-minimal Changes since v5: - Rebased on v6.3-rc3. Patch 1: - Set obj-y for starfive/ in drivers/clk/Makefile. Patch 2: - Sorted the StarFive entries alphabetically in MAINTAINERS. Patch 3: - Fixed the build error which caused by renaming the header without changing the users of the header. Patch 4: - Fixed the errors reported by checkpatch.pl. Patch 6: - Set obj-y for starfive/ in drivers/reset/Makefile. Patch 13: - Set the timer clock flags as 0. v5: https://lore.kernel.org/all/20230311090733.56918-1-hal.feng@starfivetech.com/ Changes since v4: - Rebased on v6.3-rc1. - Added two patches to replace SOC_STARFIVE with ARCH_STARFIVE. - Added Tested-by tag for Tommaso. Patch 9: - Set GMAC1 related clocks as optional inputs. - Dropped PLL clock definitions. Patch 10: - Set GMAC0 related clocks and RTC oscillator as optional inputs. - Sorted the clocks. Patch 11: - Replaced SOC_STARFIVE with ARCH_STARFIVE. - Added macros for PLL clocks and adjusted the code properly to make it easier to add the PLL clock driver later. - Updated the clock flags. Patch 12: - Built as a module by default. - Sorted the clocks. - Updated the clock flags. Patch 13: - Replaced "default CLK_STARFIVE_JH7110_SYS" with "default ARCH_STARFIVE". - Renamed "reset_info" struct to "jh7110_reset_info" and moved its definition into the driver. - Put jh7110_sys_info and jh7110_sys_info before the probe().
