Where can I find CMSIS-Driver implementations as open-source repositories

Hi ARM experts,

I need to bring up this question again: CMSIS-Driver implementations as open source repositories - Keil forum - Support forums - Arm Community

I'm Henry from Siemens SI BP, working on the firmware platform, and we decided to use CMSIS-Driver (UART, I2C, SPI, etc.) as common hardware abstraction layer APIs.

What I am looking for is the source repositories (not just the source code) of the vendor specific implementations for CMSIS-Driver, which you can find the full list here MDK5 Software Packs (keil.com). For example: "Keil.STM32F7xx_DFP.2.15.0.pack" contains all existing CMSIS-Driver implementations for STM32F7xx series. Where can I find those CMSIS-Driver implementations as open-source repositories (e.g. on GitHub).Then we could follow the update, report issues, and may make contributions from our side as well.

Thank you very much!
