This patch series introduces support for SM7125 Samsung devices with the following components enabled: - Framebuffer - GPIO keys - Hall sensor - Vibrator - Regulators - Reset input - Real-time clock - SD card - UFS - USB Along with that, SM7125 was affected by a hang when launching SHM bridge. A similar issue was reported on a similar chipset: https://lore.kernel.org/all/20250721-sc7180-shm-hang-v1-1-99ad9ffeb5b4@trvn.ru/ Add SM7125 to the qcom_tzmem_blacklist to avoid hangs when booting. Signed-off-by: Erikas Bitovtas --- Changes in v2: - Renamed regulator nodes to satisfy dtbs_check. - Renamed pin configurations for SD card to satisfy dtbs_check. - Moved rmtfs_mem to the common dtsi, shifted addresses 0x1000 to the left and added "qcom,use-guard-pages". - Converted decimal 0 to hex 0x0 where applicable. - Pinctrl names are now listed after pinctrl themselves. - Renamed vol-up to button-vol-up to satisfy dtbs_check. - Framebuffer uses cont_splash_mem instead of retyping reg. - Removed pinctrl-names from vibrator. - Added a blank line at the top to the comment for &pm6150_pon - Added a comment explaining what the reserved gpio ranges are. - Added a blank line before "status = "okay"" where applicable. - Link to v1: https://patch.msgid.link/20260703-sm7125-samsung-v1-0-3e5f752048c1@gmail.com To: Bjorn Andersson To: Konrad Dybcio To: Rob Herring To: Krzysztof Kozlowski To: Conor Dooley To: Bartosz Golaszewski To: Kees Cook To: Tony Luck To: "Guilherme G.
