2018-07-30ata: ahci: Enable DEVSLP by default on x86 with SLP_S0Srinivas Pandruvada
One of the requirement for modern x86 system to enter lowest power mode (SLP_S0) is SATA IP block to be off. This is true even during when platform is suspended to idle and not only in opportunistic (runtime) suspend. Several of these system don't have traditional ACPI S3, so it is important that they enter SLP_S0 state, to avoid draining battery even during suspend. So it is important that out of the box Linux installation reach this state. SATA IP block doesn't get turned off till SATA is in DEVSLP mode. Here user has to either use scsi-host sysfs or tools like powertop to set the sata-host link_power_management_policy to min_power. This change sets by default link power management policy to min_power with partial (preferred) or slumber support on idle for some platforms. To avoid regressions, the following conditions are used: - User didn't override the policy from module parameter - The kernel config is already set to use med_power_with_dipm or deeper - System is a SLP_S0 capable using ACPI low power idle flag This combination will make sure that systems are fairly recent and since getting shipped with SLP_S0 support, the DEVSLP function is already validated.

2018-07-30ata: ahci: Support state with min power but Partial low power stateSrinivas Pandruvada
Currently when min_power policy is selected, the partial low power state is not entered and link will try aggressively enter to only slumber state. Add a new policy which still enable DEVSLP but also try to enter partial low power state. This policy is presented as "min_power_with_partial". For information the difference between partial and slumber Partial – PHY logic is powered up, and in a reduced power state. The link PM exit latency to active state maximum is 10 ns. Slumber – PHY logic is powered up, and in a reduced power state. The link PM exit latency to active state maximum is 10 ms. Devslp – PHY logic is powered down. The link PM exit latency from this state to active state maximum is 20 ms, unless otherwise specified by DETO.

2018-07-30media: em28xx: explicitly disable TS packet filterRobert Schlabbach
The em28xx driver never touched the EM2874 register bits that control the transport stream packet filters, leaving them at whatever default the firmware has set. E.g. the Pinnacle 290e disables them by default, while the Hauppauge WinTV dualHD enables discarding NULL packets by default. However, some applications require NULL packets, e.g. to determine the load in DOCSIS segments, so discarding NULL packets is undesired for such applications. This patch simply extends the bit mask when starting or stopping the transport stream packet capture, so that the filter bits are cleared. It has been verified that this makes the Hauppauge WinTV dualHD pass an unfiltered DVB-C stream including NULL packets, which it didn't before.

2018-07-30mmc: mmci: Initial support to manage variant specific callbacksUlf Hansson
To be able to better support different mmci variants, we need to be able to use variant specific callbacks, rather than continue to sprinkle the code with additional variant data. To move in this direction, let's add an optional ->init() callback to the variant data struct, which variants shall use to assign the mmci_host_ops pointer. Using an ->init() callback enables us to partition the code between different files. To allow separate mmci variant files to implement the variant specifics, let's also move the definition of the struct variant_data to the common mmci header file.

Friio device contains "gl861" bridge and "tc90522" demod, for which the separate drivers are already in the kernel.
