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.Suggested-by: Hans de Goede

'rc' is known to be 0 at this point.
If 'platform_get_resource()' or 'devm_ioremap()' fail, return -ENOMEM
instead of 0 which means success.tj: Changed error code from -ENOMEM to -ENODEV for get_resource
failure as suggested by Sergei.Signed-off-by: Christophe JAILLET

All platforms using this driver now register the SATA refclk. Remove
the hardcoded default value from the driver and instead read the rate
of the external clock and calculate the required MPY value from it.Signed-off-by: Bartosz Golaszewski

We have a use case with the da850 SATA controller where at PLL0
frequency of 456MHz (needed to properly service the LCD controller)
the chip becomes unstable and the hardreset operation is ignored the
first time 50% of times.The sata core driver already retries to resume the link because some
controllers ignore writes to the SControl register, but just retrying
the resume operation doesn't work - we need to issue he phy/wake reset
again to make it work.Reimplement ahci_hardreset() in the driver and poke the controller a
couple times before really giving up.Signed-off-by: Bartosz Golaszewski

There's an issue with the da850 SATA controller: if port multiplier
support is compiled in, but we're connecting the drive directly to
the SATA port on the board, the drive can't be detected.To make SATA work on the da850-lcdk board: first try to softreset
with pmp - if the operation fails with -EBUSY, retry without pmp.Signed-off-by: Bartosz Golaszewski

In preparation for using two clocks in the driver (the sysclk2-based
clock and the external REFCLK), check if we got the functional clock
after calling ahci_platform_get_resources(). If not, retry calling
clk_get() with con_id specified.Signed-off-by: Bartosz Golaszewski

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().Signed-off-by: Akinobu Mita

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.Signed-off-by: Antoine Ténart

Add a dynamic host_flags argument to make ahci_platform_init_host more flexible,
then remove the AHCI_HFLAGS(...) argument from some driver's ata_port_info,
and pass that in as the new argument.Cc: Hans de Geode

Add the new ahci_da850 host driver.
Platform changes needed to make DaVinci DA850 SATA AHCI support
fully functional are in the separate "ARM: davinci: da850: update
SATA AHCI support" commit.Please note that this driver doesn't have the superfluous clock
control code as clock is already handled by the generic AHCI
platform library code.Cc: Sekhar Nori
