Shawn Lin 6c71bcdab9 UPSTREAM: PCI: rockchip: Add quirk to disable RC's ASPM L0s ... Rockchip's RC outputs 100MHz reference clock but there are two methods for PHY to generate it. (1)One of them is to use system PLL to generate 100MHz clock and the PHY will relock it and filter signal noise then outputs the reference clock. (2)Another way is to share Soc's 24MHZ crystal oscillator with PHY and force PHY's DLL to generate 100MHz internally. When using case(2), the exit from L0s doesn't work fine occasionally due to the broken design of RC receiver's logical circuit. So even if we use extended-synch, it still fails for PHY to relock the bits from FTS sometimes. This will hang the system. Maybe we could argue that why not use case(1) to avoid it? The reason is that as we could see the reference clock is derived from system PLL and the path from it to PHY isn't so clean which means there are some noise introduced by power-domain and other buses can't be filterd out by PHY and we could see noise from the frequency spectrum by oscilloscope. This makes the TX compatibility test a little difficult to pass the spec. So case(1) and case(2) are both used indeed now. If using case(2), we should disable RC's L0s support, and that is why we need this property to indicate this quirk. Also after checking quirk.c, I noticed there is already a quirk for disabling L0s unconditionally, quirk_disable_aspm_l0s. But obviously we shouldn't do that as mentioned above that case(1) could still works fine with L0s.
