2020-07-28ARM: socfpga: PM: add missing put_device() call in ↵Yu Kuai
socfpga_setup_ocram_self_refresh() if of_find_device_by_node() succeed, socfpga_setup_ocram_self_refresh doesn't have a corresponding put_device(). Thus add a jump target to fix the exception handling for this function implementation.

2020-07-28ARM: mstar: Add IMI SRAM regionDaniel Palmer
All MStar v7 SoCs have an internal SRAM region that is between 64KB (infinity2m) and 128KB(infinity3, mercury5). The region is always at the same base address and is used for the second stage loader (MStar IPL or u-boot SPL) and will be used for the DDR self-refresh entry code within the kernel eventually. This patch adds a 128KB region to the SoC and the minimum 64KB SRAM region to the base dtsi. Families with more SRAM will override the size in their family level dtsi.

2020-07-25ARM: dts: keystone-k2g-evm: fix rgmii phy-mode for ksz9031 phyGrygorii Strashko
Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on keystone-k2g-evm board. The above board have phy-mode = "rgmii-id" and it is worked before because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay by default. After above commit, the KSZ9031 PHY starts handling phy mode properly and enables both RX and TX delays, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.
