Subject: [BUG] - Short freezes in gameplay due to MMC_CAP_AGGRESSIVE_PM on
 RTS525A card reader

Hello,

I have several handheld devices that have a Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader and I am running into an issue on all of them when I try to play games off of my SanDisk Extreme PRO Micro SD cards. 

I have two SD cards, a 1TB and a 2TB model, and while playing games off of either one there are frequent freezes in gameplay. When this happens, the kernel has some mmc and rtsx errors:

As a workaround, not setting MMC_CAP_AGGRESSIVE_PM seems to resolve the issue:

I think what's happening here is that RTS525A shuts off power to the card reader when games are idle for 10 seconds or more, and then when the game goes to load new assets it has to go through the whole re-tuning process which takes 1-2 seconds. The other brands of card readers I have keep the device powered the whole time so they do not have this issue, and that's what untagging MMC_CAP_AGGRESSIVE_PM seems to mimic. 

Should I upstream the above as a quirk or is there further debugging I can assist with to find another workaround for the gameplay stutter? I've found a couple other bugs with the card reader too but I will send out separate threads to keep things organized.

Thanks!

Matt
