Introduce support for the Qualcomm IPQ50xx SoC. This series adds support for the following components: - minimal boot support: GCC/pinctrl/watchdog/CPUFreq/SDI (upstreamed) - USB2 (upstreamed) - Thermal/Tsens - PCIe gen2 1&2-lane PHY and controller - PWM and PWM LED - QPIC SPI NAND controller - CMN PLL Block (provider of fixed rate clocks to GCC/ethernet/more.) - Ethernet: IPQ5018 Internal GE PHY (1 gbps) - Remoteproc MPD driver for IPQ5018 (2.4G) & QCN6122 (5/6G) Wifi Co-developed-by: Ziyang Huang <hzyitc@outlook.com> Signed-off-by: Ziyang Huang <hzyitc@outlook.com> Signed-off-by: George Moussalem <george.moussalem@outlook.com> Link: https://github.com/openwrt/openwrt/pull/17182 Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] thermal/drivers/qcom: Add new feat for soc without rpm
|
|
Date: Fri, 22 Sep 2023 17:21:14 +0530
|
|
|
|
In IPQ5018, Tsens IP doesn't have RPM. Hence the early init to
|
|
enable tsens would not be done. So add a flag for that in feat
|
|
and skip enable checks. Without this, tsens probe fails.
