2014-04-29 | fsl/pci: The new pci suspend/resume implementation | Wang Dongsheng | |
If we do nothing in suspend/resume, some platform PCIe ip-block can't guarantee the link back to L0 state from sleep, then, when we read the EP device will hang. Only we send pme turnoff message in pci controller suspend, and send pme exit message in resume, the link state will be normal. When we send pme turnoff message in pci controller suspend, the links will into l2/l3 ready, then, host cannot communicate with ep device, but pci-driver will call back EP device to save them state. So we need to change platform_driver->suspend/resume to syscore->suspend/resume. So the new suspend/resume implementation, send pme turnoff message in suspend, and send pme exit message in resume. And add a PME handler, to response PME & message interrupt. Change platform_driver->suspend/resume to syscore->suspend/resume. pci-driver will call back EP device, to save EP state in pci_pm_suspend_noirq, so we need to keep the link, until pci_pm_suspend_noirq finish.

2013-03-21 | powerpc/fsl: remove extraneous DIU platform functions | Timur Tabi | |
The Freescale DIU driver was recently updated to not require every DIU platform function, so now we can remove the unneeded functions from some boards. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org> | |||
2012-09-12 | powerpc/fsl-pci: Unify pci/pcie initialization code | Jia Hongtao | |
We unified the Freescale pci/pcie initialization by changing the fsl_pci to a platform driver. In previous PCI code architecture the initialization routine is called at board_setup_arch stage. Now the initialization is done in probe function which is architectural better. Also It's convenient for adding PM support for PCI controller in later patch. Now we registered pci controllers as platform devices. So we combine two initialization code as one platform driver.

2012-09-12 | powerpc/85xx: introduce support for the Freescale / iVeia P1022RDK | Timur Tabi | |
The Freescale / iVeia P1022RDK reference board is a small-factor board with a Freescale P1022 SOC. It includes: 1) 512 MB 64-bit DDR3-800 (max) memory 2) 8MB SPI serial flash memory for boot loader 3) Bootable 4-bit SD/MMC port 4) Two 10/100/1000 Ethernet connectors 5) One SATA port 6) Two USB ports 7) One PCIe x4 slot 8) DVI video connector 9) Audio input and output jacks, powered by a Wolfson WM8960 codec. Unlike the P1022DS, the P1022RDK does not have any localbus devices, presumably because of the localbus / DIU multiplexing restriction of the P1022 SOC.
