[ Upstream commit cee82eb9532090cd1dc953e845d71f9b1445c84e ]

The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.

[ Upstream commit 19c624c6b29e244c418f8b44a711cbf5e82e3cd4 ]

This commit corrects max and step values for v4l2 control for
V4L2_CID_JPEG_RESTART_INTERVAL. Max should be 0xffff and step should be 1.
It was found by using v4l2-compliance tool and checking result of
VIDIOC_QUERY_EXT_CTRL/QUERYMENU test.
Previously it was complaining that step was bigger than difference
between max and min.

[ Upstream commit e7e7e0d7beafebd11b0c065cd5fbc1e5759c5aab ]

If the clock tree is not fully populated when the timer-sun5i init code
is called, attempts to get the clock rate for the timer would fail and
return 0.

Make the init code for both clock events and clocksource check the
returned clock rate and fail gracefully if the result is 0, instead of
causing a divide by 0 exception later on.

From: Marek Szyprowski <m.szyprowski@samsung.com>

[ 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.

[ Upstream commit 7f0d078667a494466991aa7133f49594f32ff6a2 ]

Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
the call to _enable() conditional based on no oh->rst_lines_cnt. This
caused the return value to be potentially uninitialized. Curiously we see
no compiler warnings for this, probably as this gets inlined.

We call _setup_reset() from _setup() and only _setup_postsetup() if the
return value is zero. Currently the return value can be uninitialized for
cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

[ 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.

From: Antonio Borneo <antonio.borneo@st.com>

[ Upstream commit 5da202c88f8c355ad79bc2e8eb582e6d433060e7 ]

The field "name" in struct ptp_clock_info has a fixed size of 16
chars and is used as zero terminated string by clock_name_show()
in drivers/ptp/ptp_sysfs.c
The current initialization value requires 17 chars to fit also the
null termination, and this causes overflow to the next bytes in
the struct when the string is read as null terminated:
	hexdump -C /sys/class/ptp/ptp0/clock_name
	00000000  73 74 6d 6d 61 63 5f 70  74 70 5f 63 6c 6f 63 6b  |stmmac_ptp_clock|
	00000010  a0 ac b9 03 0a                                    |.....|
where the extra 4 bytes (excluding the newline) after the string
represent the integer 0x03b9aca0 = 62500000 assigned to the field
"max_adj" that follows "name" in the same struct.

There is no strict requirement for the "name" content and in the
comment in ptp_clock_kernel.h it's reported it should just be 'A
short "friendly name" to identify the clock'.
Replace it with "stmmac ptp".

[ Upstream commit bd73dfabdda280fc5f05bdec79b6721b4b2f035f ]

Illegal memory will be touch if SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3
(41) exceed the size of structure sdma_script_start_addrs(40),
thus cause memory corrupt such as slob block header so that kernel
trap into while() loop forever in slob_free(). Please refer to below
code piece in imx-sdma.c:
for (i = 0; i < sdma->script_number; i++)
	if (addr_arr[i] > 0)
		saddr_arr[i] = addr_arr[i]; /* memory corrupt here */
That issue was brought by commit a572460be9cf ("dmaengine: imx-sdma: Add
support for version 3 firmware") because SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3
(38->41 3 scripts added) not align with script number added in
sdma_script_start_addrs(2 scripts).

From: Mans Rullgard <mans@mansr.com>

[ Upstream commit fed8d8c7a6dc2a76d7764842853d81c770b0788e ]

The driver does the wrong thing when cs_change is set on a non-last
xfer in a message.  When cs_change is set, the driver deactivates the
CS and leaves it off until a later xfer again has cs_change set whereas
it should be briefly toggling CS off and on again.

This patch brings the behaviour of the driver back in line with the
documentation and common sense.  The delay of 10 us is the same as is
used by the default spi_transfer_one_message() function in spi.c.

[ Upstream commit 39a1a8941b27c37f79508426e27a2ec29829d66c ]

Older versions of the Juno *SoC* TRM [1] recommended that the UART clock
source should be 7.2738 MHz, whereas the *system* TRM [2] stated a more
correct value of 7.3728 MHz. Somehow the wrong value managed to end up in
our DT.

Doing a prime factorisation, a modulo divide by 115200 and trying
to buy a 7.2738 MHz crystal at your favourite electronics dealer suggest
that the old value was actually a typo. The actual UART clock is driven
by a PLL, configured via a parameter in some board.txt file in the
firmware, which reads 7.37 MHz (sic!).

Fix this to correct the baud rate divisor calculation on the Juno board.
