Re: [PATCH v4 2/4] clk: imx8mq: Add a clock driver for the imx8mq

Hi Angus,

Am Di., 15. März 2022 um 14:09 Uhr schrieb Angus Ainslie angus@akkea.ca:

This is a DM clock driver based off the imx8mm u-boot driver and the linux kernel driver.

All of the PLLs and clocks are initialized so the subsystems below are functional and tested.

1. USB host and peripheral
2. ECSPI
3. UART
4. I2C all busses
5. USDHC for eMMC support
6. USB storage
7. GPIO
8. DRAM
