[ Upstream commit d968e99488c4b08259a324a89e4ed17bf36561a4 ]
Link startup becomes unreliable for Intel Alder Lake based host
controllers when a 2nd DME_LINKSTARTUP is issued unnecessarily. Employ
UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE to suppress that from happening.

commit bb44826c3bdbf1fa3957008a04908f45e5666463 upstream.
Intel platforms with UFS, can support Suspend-to-Idle (S0ix) and
Suspend-to-RAM (S3). For S0ix the link state should be HIBERNATE. For
S3, state is lost, so the link state must be OFF. Driver policy,
expressed by spm_lvl, can be 3 (link HIBERNATE, device SLEEP) for S0ix
but must be changed to 5 (link OFF, device POWEROFF) for S3.
Fix support for S0ix/S3 by switching spm_lvl as needed. During suspend
->prepare(), if the suspend target state is not Suspend-to-Idle, ensure
the spm_lvl is at least 5 to ensure that resume will be possible from
deep sleep states. During suspend ->complete(), restore the spm_lvl to
its original value that is suitable for S0ix.
This fix is first needed in Intel Alder Lake based controllers.

[ Upstream commit 01aad16c2257ab8ff33b152b972c9f2e1af47912 ]
On Google gs101, the number of UTP transfer request slots (nutrs) is 32,
and in this case the driver ends up programming the UTRL_NEXUS_TYPE
incorrectly as 0.
This is because the left hand side of the shift is 1, which is of type
int, i.e. 31 bits wide. Shifting by more than that width results in
undefined behaviour.
Fix this by switching to the BIT() macro, which applies correct type
casting as required. This ensures the correct value is written to
UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift
warning:
UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21
shift exponent 32 is too large for 32-bit type 'int'
For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE
write.

commit 6de7435e6b81fe52c0ab4c7e181f6b5decd18eb1 upstream.
Intel MTL-like host controllers support auto-hibernate. Using
auto-hibernate with manual (driver initiated) hibernate produces more
complex operation. For example, the host controller will have to exit
auto-hibernate simply to allow the driver to enter hibernate state
manually. That is not recommended.
The default rpm_lvl and spm_lvl is 3, which includes manual hibernate.
Change the default values to 2, which does not.
Note, to be simpler to backport to stable kernels, utilize the UFS PCI
driver's ->late_init() call back. Recent commits have made it possible
to set up a controller-specific default in the regular ->init() call
back, but not all stable kernels have those changes.

commit 4428ddea832cfdb63e476eb2e5c8feb5d36057fe upstream.
UFSHCD core disables the UIC completion interrupt when issuing UIC
hibernation commands, and re-enables it afterwards if it was enabled to
start with, refer ufshcd_uic_pwr_ctrl(). For Intel MTL-like host
controllers, accessing the register to re-enable the interrupt disrupts
the state transition.
Use hibern8_notify variant operation to disable the interrupt during the
entire hibernation, thereby preventing the disruption.

commit ceef938bbf8b93ba3a218b4adc244cde94b582aa upstream.
v1 of the patch which introduced the ufshcd_vops_hibern8_notify()
callback used a bool instead of an enum. In v2 this was updated to an
enum based on the review feedback in [1].
ufs-exynos hibernate calls have always been broken upstream as it
follows the v1 bool implementation.

[ Upstream commit b715c55daf598aac8fa339048e4ca8a0916b332e ]
Currently, HCLKDIV is written to and then completed with an mb().
mb() ensures that the write completes, but completion doesn't mean that it
isn't stored in a buffer somewhere. The recommendation for ensuring this
bit has taken effect on the device is to perform a read back to force it to
make it all the way to the device. This is documented in device-io.rst and

Let's do that to ensure the bit hits the device. Because the mb()'s purpose
wasn't to add extra ordering (on top of the ordering guaranteed by
writel()/readl()), it can safely be removed.

[ Upstream commit 86bd0c4a2a5dc4265884648cb92c681646509692 ]
The Exynos UFS controller only supports scatter/gather list elements that
are aligned on a 4 KiB boundary. Fix DMA alignment in case PAGE_SIZE !=
4096. Rename UFSHCD_QUIRK_ALIGN_SG_WITH_PAGE_SIZE into
UFSHCD_QUIRK_4KB_DMA_ALIGNMENT.

Pull SCSI updates from James Bottomley:
"Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
mpt3sas, target). The biggest change (from my biased viewpoint) being
that the mpi3mr now attached to the SAS transport class, making it the
first fusion type device to do so.
Beyond the usual bug fixing and security class reworks, there aren't a
huge number of core changes"

Mediatek UFS does not want to toggle write booster during clock scaling.
Permit host driver to disable wb toggling during clock scaling.
Introduce a flag UFSHCD_CAP_WB_WITH_CLK_SCALING to decouple WB and clock
scaling. UFSHCD_CAP_WB_WITH_CLK_SCALING is only valid when
UFSHCD_CAP_CLK_SCALING is set. Just like UFSHCD_CAP_HIBERN8_WITH_CLK_GATING
is valid only when UFSHCD_CAP_CLK_GATING set.
Set UFSHCD_CAP_WB_WITH_CLK_SCALING for qcom to compatible legacy design at
the same time.

Provide clk-scaling feature in MediaTek UFS platforms.
MediaTek platform supports clk-scaling by switching parent clock mux of
UFSHCI main clocks: ufs_sel.
The driver needs to prevent changing the rate of ufs_sel because its parent
PLL clock may be shared between multiple IPs. In order to achieve this
goal, the maximum and minimum clock rates of ufs_sel defined in dts should
match the rate of "ufs_sel_max_src" and "ufs_sel_min_src" respectively.

dsm_fns is a bitmap, and it is 0-indexed according to the check in
__intel_dsm function. But common initialization was checking it as if it
was 1-indexed. This patch corrects the discrepancy. This change won't break
any existing calls to the function, since before the change both bits 0 and
1 were checked and needed to be set.

phy_power_on was called before phy_init
To address this, we need to remove phy_power_on from exynos_ufs_phy_init()
and move it after phy_init. phy_power_off and phy_exit are also necessary
in exynos_ufs_remove().
