2017-11-27ARM: dts: colibri-imx7: limit eMMC SDHC frequency to 100MHzStefan Agner
During temperature testing modules print the following error every now and then: [ 12.231006] mmc0: Timeout waiting for hardware interrupt. retries left=0 opcode=12 Often the SDHC controller/driver does not recover from the issue which leads to a Kernel panic (e.g. during boot the kernel can not mount the root fs). Lowering the frequency to 100MHz proves to be stable and affects effective bandwith by less than 5%.

This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers.

[ Upstream commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 ] Certain HP keyboards would keep inputting a character automatically which is the wake-up key after S3 resume On some AMD platforms USB host fails to respond (by holding resume-K) to USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures that resume is signaled for at least 20 ms (TDRSMDN), which is defined in USB 2.0 spec. The result is that the keyboard is out of function. In SNPS USB design, the host responds to the resume request only after system gets back to S0 and the host gets to functional after the internal HW restore operation that is more than 1 second after the initial resume request from the USB device. As a workaround for specific keyboard ID(HP Keyboards), applying port reset after resume when the keyboard is plugged in.
