George Moussalem 34d9172655 qualcommax: add ipq50xx target
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

Subject: [PATCH] clk: qcom: apss-ipq-pll: fix PLL rate for IPQ5018
Date: Tue, 26 Mar 2024 14:34:11 +0100
According to ipq5018.dtsi, the maximum supported rate by the
CPU is 1.008 GHz on the IPQ5018 platform, however the current
configuration of the PLL results in 1.2 GHz rate.
Change the 'L' value in the PLL configuration to limit the
rate to 1.008 GHz. The downstream kernel also uses the same
value [1]. Also add a comment to indicate the desired
frequency.
