From: Sven Peter <sven@kernel.org>
Enable drivers for hardware present on Apple Silicon machines. None of
these drivers are critical so build them as modules. The reset and RTC
macsmc drivers would be useful as built-in drivers but they have large
dependencies so keep them as modules.
The size increases are minor and are offsetted by already merged
"default ARCH_APPLE" removals from the linked original submission.

Changes compared to the original submission:
- Remove AIC and APPLE_PMGR_PWRSTATE as those are selected by ARCH_APPLE
- Add new macsmc drivers (mfd, reset, hwmon, rtc and gpio)
- Add BACKLIGHT_APPLE_DWI, DRM_PANEL_SUMMIT and NVMEM_APPLE_SPMI
(suggested by Nick Chan)
- Add PWM_APPLE and APPLE_M1_CPU_PMU

Good catch, I missed it in Nick's list. Comma or new line separated
entries would have been easier to read. I also missed the network and
bluetooth devices:
- BRCMFMAC_PCIE
- BT_HCIBCM4377
- TIGON3
- AQTION
Missing as well although only in linux-next is PHY_APPLE_ATC
What is the merge policy for defconfig changes? If this can be merged
for v6.19 I won't bother with a v2 and add them later in a subsequent
change.
If it will be picked up only for the next cycle (v7.0?) I'll send a v2
with the missing configs. Any advise how to deal with PHY_APPLE_ATC? It
depends on commit 8e98ca1e74db ("phy: apple: Add Apple Type-C PHY")
currently only in

We can then follow up next cycle with the missings ones and PHY_APPLE_ATC which should be in Torvald's tree by then. Not sure about the Kconfig.platforms change though, does that go through the SoC tree or the arm64 tree? Sven
