My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A feature has been added in the libahci driver: the possibility to set a new flag in hpriv->flags to let the core handle PHY suspend/resume automatically.

Looking at the SATA PHY initialization routine, there is a comment about "vendor specific" registers. Two registers are mentioned. They are not initialized there in the firmware because they are AHCI related, while the firmware at this location does only PHY configuration. The solution to avoid doing such initialization is relying on U-Boot. While this work at boot time, U-Boot is definitely not going to run during a resume after suspending to RAM. Two possible solutions were considered: * Fixing the firmware. * Fixing the kernel driver. The first solution would take ages to propagate, while the second solution is easy to implement as the driver as been a little bit reworked to prepare for such platform configuration. Hence, this patch adds an Armada 3700 configuration function to set these two registers both at boot time (in the probe) and after a suspend (in the resume path).

Commit 15d3ce7b63bd ("ata: ahci_mvebu: add support for Armada 3700 variant") introduced Armada 3700 support. As opposed to Armada 38x SoCs, the 3700 variants do not have to configure mbus and the regret option. This patch took care of avoiding such configuration when not needed in the probe function, but failed to do the same in the resume path. While doing so looks harmless by experience, let's clean the driver logic and avoid doing this useless configuration with Armada 3700 SoCs. Because the logic is very similar between these two places, it has been decided to factorize this code and put it in a "Armada 38x configuration function". This function is part of a new (per-compatible) platform data structure, so that the addition of such configuration function for Armada 3700 will be eased.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of the libahci does not take into account the new PHY framework. Correct the situation by adding a call to phy_set_mode() before phy_power_on(). PHYs should also be handled at suspend/resume time. For this, call ahci_platform_enable/disable_phys() at suspend/resume_host() time. These calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of the libahci driver must set manually in hpriv->flags at probe time. This is to avoid breaking users that have not been tested with this change.
