The Eliza EVK exposes two PCIe ports: - PCIe0 drives an M.2 E key connector. The 3.3V supply is GPIO-controlled via a TCA9538 I/O expander on I2C4. The slot hosts a WLAN module (connected over PCIe) and a Bluetooth device (connected over UART5), modelled with the pcie-m2-e-connector binding. - PCIe1 (8GT/s x2) connects to a Toshiba TC9563 PCIe switch, whose management interface sits on I2C4 (address 0x77). The TC9563 RESX# and PERST# lines are OR-ed internally; reset is driven via a TLMM GPIO on the RESX# pin. The iommu-map covers all downstream switch ports (SID range 0x1400-0x1408). The M.2 WLAN module carries a Qualcomm QCC2072 Bluetooth chip. A device-ID entry is added to the M.2 power sequencer so the serdev node for the BT UART interface is created on PCI enumeration. Bluetooth is enabled with this patch https://lore.kernel.org/all/20260529175822.3366535-1-yepuri.siddu@oss.qualcomm.com/ This seris Depends-on: https://lore.kernel.org/all/20260610-eliza_dt-v1-1-7bb72b75fc5b@oss.qualcomm.com/ https://lore.kernel.org/all/20260630-eliza-dts-qcs-evk-v4-3-18cbbdba6e7e@oss.qualcomm.com/ https://lore.kernel.org/all/20260630-dts-qcom-eliza-mtp-evk-add-pmics-v1-1-f4f320f7c88b@oss.qualcomm.com/ Signed-off-by: Krishna Chaitanya Chundru --- Krishna Chaitanya Chundru (3): arm64: dts: qcom: eliza-evk: Add PCIe0 with M.2 E key connector arm64: dts: qcom: eliza-evk: Add PCIe1 with TC9563 PCIe switch power: sequencing: pwrseq-pcie-m2: Add QCC2072 BT PCI device ID arch/arm64/boot/dts/qcom/eliza-evk.dtsi | 283 ++++++++++++++++++++++++++++++ arch/arm64/boot/dts/qcom/eliza.dtsi | 1 + drivers/power/sequencing/pwrseq-pcie-m2.c | 2 + 3 files changed, 286 insertions(+) --- base-commit: dc59e4fea9d83f03bad6bddf3fa2e52491777482 change-id: 20260629-eliza_evk-6f30686b161f prerequisite-message-id: <20260610-eliza_dt-v1-1-7bb72b75fc5b@oss.qualcomm.com> prerequisite-patch-id: b6c6123bc2cb3a5e6c309c1cfcca80f7f950d390 prerequisite-patch-id: 9e10dfbe360941cdac0300aaf163149755952f9f prerequisite-patch-id: fecce0170351baf00cbe8f6b302d1def4d99bbfc prerequisite-patch-id: 97cd6cb495fdd198f6de7fbe45ef32e4a638ec9c prerequisite-message-id: <20260630-dts-qcom-eliza-mtp-evk-add-pmics-v1-1-f4f320f7c88b@oss.qualcomm.com> prerequisite-patch-id: f3615b5c1e2222a2491f862a7fba3994058ecc53 Best regards, -- Krishna Chaitanya Chundru
