Subject[Patch v2 0/3] misc: pch_phub: Add quirks for MIPS Boston platform
Date
Hi,

These are a few patches for using the EG20T UART on the Imagination
Technologies Boston development platform

2 quirks needed
- Pass a specific value for the prefetch register from DT instead of using
the hard-coded default.
- Add a quirk for using the internal 25MHz clock source for the UART block

The patches for Boston platform are inflight.
https://patchwork.kernel.org/patch/8200941/

So pasting a DT node snippet here.

+ eg20t_pch@2,0,0 {
+ compatible = "pci8086,8801";
+ reg = <0x00020000 0 0 0 0>;
+
+ intel,eg20t-prefetch = <0>;
+ };
+ eg20t_uart0@02,10,1 {
+ compatible = "pci8086,8811";
+ reg = <0x00025100 0 0 0 0>;
+
+ clock-frequency = <25000000>;
+ };

Suggestions and feedback welcome.

Based on v4.8-rc1

Regards,
ZubairLK
