And no, just because earlier Hector added stuff in reversed order, is not a reason to keep doing the same. Best regards, Krzysztof

In Apple-specific bindings maybe some chronological order was chosen earlier. If there is some known order, you can keep it. But for common bindings (so like one here)we prefer alphabetical.

Hi, This series adds device trees for all A7-A11 SoC based iPhones, iPads, iPod touches and Apple TVs. The following devices has been excluded from this series: - All T2 devices (A10-based): bootloader does not work (yet) - HomePod: Not tested, and it's also a different form factor To pass `make dtbs_check`, please install the latest dtschema from the main branch, for the `television` chassis type. This series supports the following on all devices: - SMP (spin-table) - UART - simple-framebuffer - watchdog - timer - pinctrl - AIC interrupts The following is supported on A7-A10: - Buttons and switches (with pinctrl) The buttons on A11 based devices like the iPhone X is a subdevice of the not yet supported SMC. Patch dependencies: - The required AIC patches[1] has been sitting in linux-next since next-20240906, through the tip tree. - The important serial fixes[2] has been sitting in linux-next since next-20240913, through the tty tree. - The optional patch to disable 32-bit EL0 on A10(X)[3] has not received any comments (v1 or v2). - A trivial patch to increase the reset delay in the watchdog driver[4] are needed on some SoCs to avoid the "Reboot Failed" message. It has been reviewed. (The system will reset regardless of the patch) Authorship information: - The commits to actually add the dts files are mostly made by Konrad, and Konrad's sign-off is added by me with permission. I also updated the Konrad's email in the actual dts files. Konrad can confirm this. - Everything else is entirely made by me. Changes since v2: - Removed A10 cpufreq. The loader may be missing some initialization code that just happened to be performed by some versions of the firmware as well, given the inconsistent behavior on different devices. It is also possible that the driver needs to be modified, I do not know and this needs more research first. - Removed Ivaylo's tags on commit to add A8X device trees, seems he does not want those anymore[5]. - Added Ivaylo's tags on commit to add A8 device tree, I have missed the tag. See [6] for source of those tags. - Added Conor's missing A-b on the commit to add A7 machine bindings. Changes since v1: - Added /chassis-type property - Added opp-microvolt in A10 cpufreq for documentation purposes - Home button is now assigned KEY_HOMEPAGE - Fixed t8010-n112.dts and do not remove it from Makefile in later commits... (iPod touch 7) In order to be consistent with the Apple ARM Machines bindings, the order of dt-bindings did not change from v1. The sort order logic here is having SoC type families in release order, and SoCs within each family in release order: - t8xxx/t700x/s5l8960x (Apple HxxP/G series, "phone"/"tablet" chips) - s5l8960x (Apple H6/A7) - t7000 (Apple H7P/A8) - t7001 (Apple H7G/A8X) - s8000/3 (Apple H8P/A9) - s8001 (Apple H8G/A9X) - t8010 (Apple H9P/A10) - t8011 (Apple H9G/A10X) - t8015 (Apple H10/A11) - t8103 (Apple H13G/M1) - t8112 (Apple H14G/M2) - t6xxx (Apple HxxJ series, "desktop" chips) - t6000 (Apple H13J(S)/M1 Pro) - t6001 (Apple H13J(C)/M1 Max) - t6002 (Apple H13J(D)/M1 Ultra) At this moment, it is expected that most hardware blocks will be 100% compatible between A-series and AX-series SoCs, though to a less extent than compatibility between desktop chips of the same generation. v1:
