Status of ADMA channel registers is not saved and restored during system

* ADMA_CH_FIFO_CTRL
* ADMA_CH_CONFIG
* ADMA_CH_CTRL
* ADMA_CH_CMD

Runtime PM calls will be inovked during system resume path if a playback

IB/mlx5: Add missing XRC options to QP optional params mask
[ Upstream commit
8f4426aa19fcdb9326ac44154a117b1a3a5ae126 ]
The QP transition optional parameters for the various transition for XRC
QPs are identical to those for RC QPs.
Many of the XRC QP transition optional parameter bits are missing from the
QP optional mask table. These omissions caused failures when doing XRC QP
state transitions.
For example, when trying to change the response timer of an XRC receive QP
via the RTS2RTS transition, the new timer value was ignored because
MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
for XRC qps for the RTS2RTS transition.
Fix this by adding the missing XRC optional parameters for all QP
transitions to the opt_mask table.

dmaengine: axi-dmac: Don't check the number of frames for alignment
[ Upstream commit
648865a79d8ee3d1aa64aab5eb2a9d12eeed14f9 ]
In 2D transfers (for the AXI DMAC), the number of frames (numf) represents
Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful
for video transfers where screen resolutions ( X * Y ) are typically
aligned for X, but not for Y.
There is no requirement for Y_LENGTH to be aligned to the bus-width (or
anything), and this is also true for AXI DMAC.
Checking the Y_LENGTH for alignment causes false errors when initiating DMA
transfers. This change fixes this by checking only that the Y_LENGTH is
non-zero.

ARM: dts: ls1021: Fix SGMII PCS link remaining down after PHY disconnect
[ Upstream commit
c7861adbe37f576931650ad8ef805e0c47564b9a ]
Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus.
But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC
are pointing towards the same internal PCS. Therefore nobody is
controlling the internal PCS of eTSEC0.
Upon initial ndo_open, the SGMII link is ok by virtue of U-boot
initialization. But upon an ifdown/ifup sequence, the code path from
ndo_open -> init_phy -> gfar_configure_serdes does not get executed for
the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII
link remains down for eTSEC0. On the LS1021A-TWR board, to signal this
failure condition, the PHY driver keeps printing
'803x_aneg_done: SGMII link is not ok'.
Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match
mdio1 device.

[ Upstream commit
509c583620e9053e43d611bf1614fc3d3abafa96 ]
The original driver by default defines num_chipselects as -1.
This actually allicates an array of 65535 entries in
of_spi_register_master.
There is a side-effect for buggy device trees that (contrary to
dt-binding documentation) have no cs-gpio defined.
This mode was never supported by the driver due to limitations
of native cs and additional code complexity and is explicitly
not stated to be implemented.
To keep backwards compatibility with such buggy DTs we limit
the number of chip_selects to 1, as for all practical purposes
it is only ever realistic to use a single chip select in
native cs mode without negative side-effects.

spi: tegra114: fix for unpacked mode transfers
[ Upstream commit
1a89ac5b91895127f7c586ec5075c3753ca25501 ]
Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked
mode when transfer length is not a multiple of requested bits per word.
unpacked mode transfers fails when the transfer includes partial bytes in
the last word.
Total words to be written/read to/from FIFO is computed based on transfer
length and bits per word. Unpacked mode includes 0 padding bytes for partial
words to align with bits per word and these extra bytes are also accounted
for calculating bytes left to transfer in the current driver.
This causes extra bytes access of tx/rx buffers along with buffer index
position crossing actual length where remain_len becomes negative and due to
unsigned type, negative value is a 32 bit representation of signed value
and transferred bytes never meets the actual transfer length resulting in
transfer timeout and a hang.
This patch fixes this with proper computation of the actual bytes to fill in
FIFO during transmit and the actual bytes to read from FIFO during receive
ignoring 0 padded bytes.

There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.
On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.
To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

If riocm_get_channel() fails, then we should just return -EINVAL.
Calling riocm_put_channel() will trigger a NULL dereference and
generally we should call put() if the get() didn't succeed.

scsi: megaraid_sas: reduce module load time
[ Upstream commit
31b6a05f86e690e1818116fd23c3be915cc9d9ed ]
megaraid_sas takes 1+ seconds to load while waiting for firmware:
[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state
This is due to the following loop in megasas_transition_to_ready(), which
waits a minimum of 1 second, even though the FW becomes ready in tens of
millisecs:
/*
* The cur_state should not last for more than max_wait secs
*/
for (i = 0; i < max_wait; i++) {
...
msleep(1000);
...
dev_info(&instance->pdev->dev, "FW now in Ready state\n");
This is a regression, caused by a change of the msleep granularity from 1
to 1000 due to concern about waiting too long on systems with coarse
jiffies.
To fix, increase iterations and use msleep(20), which results in:
[2.670627] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[2.739386] megaraid_sas 0000:03:00.0: FW now in Ready state

[ Upstream commit
ca70ea43f80c98582f5ffbbd1e6f4da2742da0c4 ]
MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to
perform low-level platform initialization. This results in a try to install
HYP stubs for the second time for each CPU and results in false HYP/SVC
mode mismatch detection. The HYP stubs are already installed at the
beginning of the kernel initialization on the boot CPU (head.S) or in the
secondary_startup() for other CPUs. To fix this issue MCPM code should use
a cpu_resume() routine without HYP stubs installation.
This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid
XU3/XU4/HC1 boards.
