ata: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

ata: libata: Make ata_platform_remove_one return void
The function returned zero unconditionally, so the function returning an int is something between useless and irritating. With the goal to make platform drivers' remove function return void, it's helpful to convert the function accordingly. This converts several drivers to the new .remove_new callback that was introduced to smoothen the platform driver conversion.

ata: ahci_sunxi: Disable DIPM
DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

drivers: ata: ahci_sunxi: Increased SATA/AHCI DMA TX/RX FIFOs
Increasing the SATA/AHCI DMA TX/RX FIFOs (P0DMACR.TXTS and .RXTS, ie. TX_TRANSACTION_SIZE and RX_TRANSACTION_SIZE) from default 0x0 each to 0x3 each, gives a write performance boost of 120 MiB/s to 132 MiB/s from lame 36 MiB/s to 45 MiB/s previously. Read performance is above 200 MiB/s. [tested on SSD using dd bs=4K/8K/12K/16K/20K/24K/32K: peak-perf at 12K]
Tested on the SBCs Banana Pi R1 (aka Lamobo R1) and Banana Pi M1 which are based on the Allwinner A20 32bit-SoC (ARMv7-a / arm-linux-gnueabihf). These devices are RaspberryPi-like small devices.
This problem of slow SATA write-speed with these small devices lasts for about 7 years now (beginning with the A10 SoC). Many commentators throughout the years wrongly assumed the slow write speed was a hardware limitation. This patch finally solves the problem, which in fact was just a hard-to-find software problem due to lack of SATA/AHCI documentation by the SoC-maker Allwinner Technology.

Since R40 need ahci_platform to handle the reset controller, we also add the new AHCI_PLATFORM_GET_RESETS flag for ahci_platform_get_resources(). This has no consequence for older platform (a10, a20) since the reset is optional.

ata: ahci_platform: fix owner module reference mismatch for scsi host
The owner module reference of the ahci platform's scsi_host is initialized to libahci_platform's one, because these drivers use a scsi_host_template defined in libahci_platform. So these drivers can be unloaded even if the scsi device is being accessed.
This fixes it by pushing the scsi_host_template from libahci_platform to all leaf drivers. The scsi_host_template is passed through a new argument of ahci_platform_init_host().

ahci_sunxi: Make AHCI_HFLAG_NO_PMP flag configurable with a module option
The use of the AHCI_HFLAG_NO_PMP flag is something which we inherited from the Allwinner android kernel sources, and I've always wanted to test if this is really necessary.
So recently I've bought a sata port multiplexer, and I've given this a test spin on both A10 and A20 devices, and it seems to work fine:
[ 2.154456] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 2.161092] ata1.15: Port Multiplier 1.2, 0x197b:0x0325 r0, 5 ports, feat 0x5/0xf [ 2.175511] ata1.00: hard resetting link [ 2.524929] ata1.00: SATA link up 3.0 Gbps (SStatus 123 SControl 320) [ 2.531430] ata1.01: hard resetting link [ 2.974465] ata1.01: link resume succeeded after 1 retries [ 3.094932] ata1.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 3.101431] ata1.02: hard resetting link [ 4.174466] ata1.02: failed to resume link (SControl 0) [ 4.180065] ata1.02: SATA link down (SStatus 0 SControl 0) (and the same for links 3 and 4)
Once the NO_PMP flag is removed it correctly sees the 2 disks which I've attached, and I can mount and use them just fine.
Unfortunately when I then directly attached a disk to the sata port on the sunxi SoC, and booted a kernel without the AHCI_HFLAG_NO_PMP flag, it would not recognize that disk.
It turns out that the sata controller in the sunxi SoCs fails to handle soft-resets issued to directly attached disks, and when pmp support is enabled the kernel will always issue a soft-reset.
So add a module parameter to enable pmp usage, and default this to off, so that directly attached disks keep working normally.

This patch moves force_port_map and mask_port_map into the ahci_host_priv structure. This allows to modify them into the AHCI framework. This is needed by the new dt bindings representing ports as the port_map mask is computed automatically.
Parameters modifying force_port_map, mask_port_map and flags have been removed from the ahci_platform_init_host() function, and inputs in the ahci_host_priv structure are now directly filed.

This patch adds support for the ahci sata controler found on Allwinner A10 and A20 SoCs to the ahci_platform driver.
Orignally written by Olliver Schinagl using the approach of having a platform device which probe method creates a new child platform device which gets driven by ahci_platform.c, as done by ahci_imx.c .
Refactored by Hans de Goede to add most of the non sunxi specific functionality to ahci_platform.c and use a platform_data pointer from of_device_id for the sunxi specific bits.

ata: ahci_sunxi: Disable DIPM commit f6bca4d91b2ea052e917cca3f9d866b5cc1d500a upstream. DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

Read performance is above 200 MiB/s. [tested on SSD using dd bs=4K/8K/12K/16K/20K/24K/32K: peak-perf at 12K] Tested on the SBCs Banana Pi R1 (aka Lamobo R1) and Banana Pi M1 which are based on the Allwinner A20 32bit-SoC (ARMv7-a / arm-linux-gnueabihf). These devices are RaspberryPi-like small devices. This problem of slow SATA write-speed with these small devices lasts for about 7 years now (beginning with the A10 SoC). Many commentators throughout the years wrongly assumed the slow write speed was a hardware limitation. This patch finally solves the problem, which in fact was just a hard-to-find software problem due to lack of SATA/AHCI documentation by the SoC-maker Allwinner Technology.

ata: add an extra argument to ahci_platform_get_resources() Add an extra argument to ahci_platform_get_resources(), that is for the bitmap representing the resource to get in this function. Currently there is no resources to be defined, so all the callers set '0' to the argument.

ata: ahci_platform: fix owner module reference mismatch for scsi host The owner module reference of the ahci platform's scsi_host is initialized to libahci_platform's one, because these drivers use a scsi_host_template defined in libahci_platform. So these drivers can be unloaded even if the scsi device is being accessed. This fixes it by pushing the scsi_host_template from libahci_platform to all leaf drivers. The scsi_host_template is passed through a new argument of ahci_platform_init_host().
