2012-07-20atl1c: fix issue of io access mode for AR8152 v2.1Cloud Ren
When io access mode is enabled by BOOTROM or BIOS for AR8152 v2.1, the register can't be read/write by memory access mode. Clearing Bit 8 of Register 0x21c could fixed the issue.

2012-05-01atl1c: enlarge L1 response waiting timerHuang, Xiong
The hardware incorrectly process L0S/L1 entrance if the chipset/root response after specific/shorter timer and cause system hang. Enlarge the timeout value to avoid this issue.

2012-05-01atl1c: refine mac address related codeHuang, Xiong
On some platform with EEPROM/OTP existing, the BIOS could overwrite a new MAC address for the NIC. so, the permanent mac address should be from BIOS. the address is restored when driver removing. Voltage raising isn't applicable for l1d. Replace swab32 with htonl for big/little endian platform. related Registers are refined as well.

2012-04-26atl1c: add function atl1c_power_savingHuang, Xiong
This function is used for suspend of S1/S3/S4 and driver remove. It sets MAC/PHY based on the WoL configuation to get lower power consumption. atl1c_phy_power_saving is renamed to atl1c_phy_to_ps_link, this function is just make PHY enter a link/speed mode to eat less power. REG_MAC_CTRL register is refined as well. Signed-off-by: xiong <xiong@qca.qualcomm.com> Tested-by: Liu David <dwliu@qca.qualcomm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-26atl1c: update PHY reset related routineHuang, Xiong
Many magic data are re-configured for PHY during its reset operation based on chip type to get better compability and stability. REG_PHY_CTRL register may be configured by BIOS before enter OS. so, the driver can't directly write to it without any Read-Op. this change also affect suspend and phy_disable routines. PHY debug ports and extension registers are refined as well. Signed-off-by: xiong <xiong@qca.qualcomm.com> Tested-by: Liu David <dwliu@qca.qualcomm.com> Signed-off-by: David S.

2012-04-26atl1c: refine SERDES-clock related codeHuang, Xiong
bit 17/18 of reg1424 must be clear for l2cb 1.x, or it will cause the write-reg operation fail without cable connected. so, please do connect the cable when apply this patch to the driver to make sure these 2bits are cleared by new driver. The revised code is move to al1c_reset_mac. SERDES register definition is refined as well. when do reset MAC, speed/duplex control right should be transferred to software before do PHY auto-neg -- by bit MASTER_CTRL_SPEED_MODE_SW. SERDES register definition is refined as well. Signed-off-by: xiong <xiong@qca.qualcomm.com> Tested-by: Liu David <dwliu@qca.qualcomm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-26atl1c: refine phy-register read/write functionHuang, Xiong
phy register is read/write via MDIO control module --- that module will be affected by the hibernate status, to access phy regs in hib stutus, slow frequency clk must be selected. To access phy extension register, the MDIO related registers are refined/updated, a _core function is re-wroted for both regular PHY regs and extension regs. existing PHY r/w function is revised based on the _core. PHY extension registers will be used for the comming patches. Signed-off-by: xiong <xiong@qca.qualcomm.com> Tested-by: Liu David <dwliu@qca.qualcomm.com> Signed-off-by: David S.

bit PCIE_PHYMISC_FORCE_RCV_DET is only for l1c&l2c to fix WoL issue, other chips set bit5 of REG_MASTER_CTRL --- this way could save more power than the former, and the bit should be kept all time. l2cb 1.x has special setting for L0S/L1 l2cb 1.x & l1d 1.x should clear Vendor Message on some platforms, otherwise it will cause the root complex hang.

2012-04-20atl1c: refine/update ASPM configurationHuang, Xiong
some platforms(BIOS or OS) may change ASPM configuration in PCI Express Link Control Register directly and dynamically regardless the device driver installation. Checking if ASPM support during the driver init phase by reading PCI Express Link Contrl Register doesn't make sense. This refine/update assume L0S/L1 is defalut enabled as hw->ctrl_flags inited. atl1c_set_aspm will set real configuration based on chip capability to hardware register. atl1c_disable_l0s_l1 and register definition of REG_PM_CTRL are refined as well.
