a=openpgp; fpr=4F9C2C8728019633893EBBB98CB81F9A72BBA155 "LSP" is ZTE's term for this part of the SoC, I suspect it stands for "low speed peripherals". The main UART is here, together with the flash controller and more surplus proprietary timers. It also has one more I2C controller that supposedly connects to a battery charger, SPI for displays and I2S for analog telephones. The boards I have don't have any of these components though. Reviewed-by: Brian Masney Signed-off-by: Stefan Dösinger --- Versions 10, 11, 12: Unchanged Version 9: Link internal parents by an (internal) clock ID rather than names. One intentional clock tree change: The PWM device's parent is the 104 MHz mpll-d6 input. With some manual experimentation I managed to make the WiFi led blink with PWM, so I could confirm which matrixcrm bit gates off its parent. Update the comments to say that the device at lspcrm+0x4000 is indeed a Pulse Width Modulator. @Sashiko: If you find any other clock tree changes compared to version 8, they are unintentional and likely bugs. Version 8: Double-checked pclk and wclk. They were the wrong way around in previous submissions. Pclk is bit 0, wclk is bit 1. Version 7: Underscore in clock names to dashes Version 6: use MFD for LSP too Version 5: Removed unused tdm_lsp_sel. Fix zx297529 vs zx297520 typo.
