Subject: [PATCH 0/4] Initial MSM8953 support
Date: Wed, 15 Jul 2026 17:17:39 +0200	[thread overview]
Message-ID: <20260715-msm8953-basic-v1-0-bc4cb5099d8e@fairphone.com> (raw)

Add clock and pinctrl drivers for the MSM8953 SoC, and activate reserved
memory carveout for MSM8953 and its sibling SDM632.

Note, that to boot successfully some more changes/quirks are needed:
* Decrease CONFIG_SYS_MALLOC_LEN to e.g. 0x1000000, default value
  crashes u-boot.
* Disable prng in msm8953.dtsi, crashes u-boot.
* Optionally disable probe of psci-sysreset driver, not functional on
  msm8953 and prohibits the pshold driver from getting active and
  working.
* Optionally add simple-framebuffer to sdm632-fairphone-fp3.dts,
  together with some lk2nd parameter this makes framebuffer somewhat
  functional. Have not played around too much to get that working 100%,
  since booting via lk2nd anyways is maybe one bootloader too much.
