Cover letter [PATCH 0/2] bus: sunxi-rsb: fix primary PMIC and peripheral IC address mapping
Quoted 14 lines · Chen-Yu Tsai
Hi Arnd, Olof,
Here are 2 fixes for the sunxi-rsb driver. There were some typos in the hardware address mapping table, but as long as the assigned address matched what the bootloader used, it still worked fine. The only indication was "failed to set runtime address" error messages which I mistook for some hardware quirk.
I looked deeper when the AC100 on my A80 boards refused to respond.
Patch 1 fixes the hardware address for primary PMICs (AXP223, AXP809...). This is the part that still worked fine despite the error because the runtime address matches the one set by the bootloader.

Patch 2 fixes the assigned runtime address for the peripheral IC (AC100/AC200). This part does not work due to the runtime address being invalid.
Maxime asked me to send them directly to you. Please pick them up for 4.4.
Applied, thanks.
In the future, for fixes late in the cycle like this, please describe in a few words in the commit message just what the error is for someone trying to use kernel without the fix, so someone just reading the changelog can determine if it's a high-priority fix or not.
Thanks!
