+Subject: ARM: zynq: Remove init_irq declaration in machine description
+
+Commit ebafed7a ("ARM: irq: Call irqchip_init if no init_irq function is
+specified") removed the need to explictly setup the init_irq field in
+the machine description when using only irqchip_init. Remove that
+declaration for zynq as well.

+Date: Mon, 2 Dec 2013 09:24:29 +0900
+Subject: serial: use platform_{get,set}_drvdata()
+
+ Use the wrapper functions for getting and setting the driver data using
+ platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
+ so we can directly pass a struct platform_device.
+
+ Also, unnecessary dev_set_drvdata() is removed, because the driver core
+ clears the driver data to NULL after device_release or on probe failure.

+Subject: tty: xuartps: Implement BREAK detection, add SYSRQ support
+
+The Cadence UART does not do break detection, even if the
+datasheet says it does. This patch adds break detection in
+software (tested in 8N1 mode only) and enables SYSRQ,
+allowing for Break-g to enter KDB and all the other goodies.

+Subject: tty: xuartps: Force enable the UART in xuartps_console_write
+
+It is possible that under certain circumstances xuartps_console_write is entered
+while the UART disabled. When this happens the code will busy loop in
+xuartps_console_putchar, since the character is never written and the TXEMPTY
+flag is never set. The result is a system lockup. This patch force enables the
+UART for the duration of xuartps_console_write to avoid this.

+Subject: tty: xuartps: Fix build error due to missing forward declaration
+
+If CONFIG_PM_SLEEP is enabled and CONFIG_SERIAL_XILINX_PS_UART_CONSOLE
+is not, a forward declaration of the uart_driver struct is not
+included, leading to a build error due to an undeclared variable.
+Fixing this by moving the definition of the struct uart_driver before
+the definition of the suspend/resume callbacks.

+Subject: GPIO: xilinx: Use __raw_readl/__raw_writel IO functions
+
+This driver can be used on Xilinx ARM Zynq platform
+where in_be32/out_be32 functions are not implemented.
+Use __raw_readl/__raw_writel functions which are
+implemented on Microblaze and PowerPC.
+For ARM readl/writel functions are used instead.
+
+The correct way how to implement this is to detect
+endians directly on IP. But for the gpio case
+without interrupt connected(it means without
+interrupt logic) there are just 2 registers
+data and tristate where auto detection can't be done.

++== Clock Controller ==
++The clock controller is a logical abstraction of Zynq's clock tree. It reads
++required input clock frequencies from the devicetree and acts as clock provider
++for all clock consumers of PS clocks.
++
++Required properties:
++ - #clock-cells : Must be 1
++ - compatible : "xlnx,ps7-clkc"
++ - ps-clk-frequency : Frequency of the oscillator providing ps_clk in HZ
++ (usually 33 MHz oscillators are used for Zynq platforms)
++ - clock-output-names : List of strings used to name the clock outputs. Shall be
++ a list of the outputs given below.
++
++Optional properties:
++ - clocks : as described in the clock bindings
++ - clock-names : as described in the clock bindings
++
++Clock inputs:
++The following strings are optional parameters to the 'clock-names' property in
++order to provide an optional (E)MIO clock source.
++ - swdt_ext_clk
++ - gem0_emio_clk
++ - gem1_emio_clk
++ - mio_clk_XX # with XX = 00..53
++...
++
++Clock outputs:
++ 0: armpll
++ 1: ddrpll
++ 2: iopll
++ 3: cpu_6or4x
++ 4: cpu_3or2x

+-
+-== PLLs ==
+-
+-Used to describe the ARM_PLL, DDR_PLL, and IO_PLL.
+-
+-Required properties:
+-- #clock-cells : shall be 0 (only one clock is output from this node)
+-- compatible : "xlnx,zynq-pll"
+-- reg : pair of u32 values, which are the address offsets within the SLCR
+- of the relevant PLL_CTRL register and PLL_CFG register respectively
+-- clocks : phandle for parent clock. should be the phandle for ps_clk
+-
+-Optional properties:
+-- clock-output-names : name of the output clock
+-
+-Example:
+- armpll: armpll {
+- #clock-cells = <0>;
+- compatible = "xlnx,zynq-pll";
+- clocks = <&ps_clk>;
+- reg = <0x100 0x110>;
+- clock-output-names = "armpll";
+- };
+-
+-== Peripheral clocks ==
+-
+-Describes clock node for the SDIO, SMC, SPI, QSPI, and UART clocks.
+-
+-Required properties:
+-- #clock-cells : shall be 1
+-- compatible : "xlnx,zynq-periph-clock"
+-- reg : a single u32 value, describing the offset within the SLCR where
+- the CLK_CTRL register is found for this peripheral
+-- clocks : phandle for parent clocks. should hold phandles for
+- the IO_PLL, ARM_PLL, and DDR_PLL in order
+-- clock-output-names : names of the output clock(s). For peripherals that have
+- two output clocks (for example, the UART), two clocks
+- should be listed.
+-
+-Example:
+- uart_clk: uart_clk {
+- #clock-cells = <1>;
+- compatible = "xlnx,zynq-periph-clock";
+- clocks = <&iopll &armpll &ddrpll>;
+- reg = <0x154>;

+Subject: clk/zynq/clkc: Add dedicated spinlock for the SWDT
+
+The clk_mux for the system watchdog timer reused the register lock
+dedicated to the Ethernet module - for no apparent reason.
+Add a lock dedicated to the SWDT's clock register to remove this
+wrong dependency.
+
+This does not fix a specific regression but the clock driver was merged
+for 3.11-rc1, so best to fix the known bugs before the release.

+Subject: clk/zynq/clkc: Add CLK_SET_RATE_PARENT flag to ethernet muxes
+
+Zynq's Ethernet clocks are created by the following hierarchy:
+ mux0 ---> div0 ---> div1 ---> mux1 ---> gate
+Rate change requests on the gate have to propagate all the way up to
+div0 to properly leverage all dividers. Mux1 was missing the
+CLK_SET_RATE_PARENT flag, which is required to achieve this.
+
+This does not fix a specific regression but the clock driver was merged
+for 3.11-rc1, so best to fix the known bugs before the release.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes
+being reparented during clk_set_rate.
+
+To avoid breaking existing platforms, all callers of clk_register_mux()
+are adjusted to pass the new flag. Platform maintainers are encouraged
+to remove the flag if they wish to allow mux reparenting on set_rate.

+Pull clock framework changes from Michael Turquette:
+"The common clk framework changes for 3.12 are dominated by clock
+driver patches, both new drivers and fixes to existing. A high
+percentage of these are for Samsung platforms like Exynos. Core
+framework fixes and some new features like automagical clock
+re-parenting round out the patches"

+
+'!' has higher precedence than comparisons so the original condition
+is equivalent to "if (xspi->remaining_bytes == 0)". This makes the
+static checkers complain.
+
+xspi->remaining_bytes is signed and from looking at the code
+briefly, I think it might be able to go negative. I suspect that
+going negative may cause a bug, but I don't have the hardware and
+can't test.

+Subject: spi/xilinx: Remove remains of of_platform device registration
+
+In the past there used to be a separate platform device type for device
+tree systems so the probe and removal functions were split into generic
+and bus sections. Since this is no longer the case simplify the code (and
+remove some unprototyped exports) by factoring everything into the bus
+probe() and remove().

+Subject: spi: bitbang: Let spi_bitbang_start() take a reference to master
+
+Many drivers that use bitbang library have a leak on probe error paths.
+This is because once a spi_master_get() call succeeds, we need an additional
+spi_master_put() call to free the memory.
+
+Fix this issue by moving the code taking a reference to master to
+spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on
+success. With this change, the caller is responsible for calling
+spi_bitbang_stop() to decrement the reference and spi_master_put() as
+counterpart of spi_alloc_master() to prevent a memory leak.
+
+So now we have below patten for drivers using bitbang library:
+
+probe:
+spi_alloc_master -> Init reference count to 1
+spi_bitbang_start -> Increment reference count
+remove:
+spi_bitbang_stop -> Decrement reference count
+spi_master_put -> Decrement reference count (reference count reaches 0)
+
+Fixup all users accordingly.

+Subject: watchdog: Get rid of MODULE_ALIAS_MISCDEV statements
+
+I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
+and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.
+
+Either the device is enumerated and the driver already has a module
+alias (e.g. PCI, USB etc.) that will get the right driver loaded
+automatically.
+
+Or the device is not enumerated and loading its driver will lead to
+more or less intrusive hardware poking. Such hardware poking should be
+limited to a bare minimum, so the user should really decide which
+drivers should be tried and in what order. Trying them all in
+arbitrary order can't do any good.
+
+On top of that, loading that many drivers at once bloats the kernel
+log. Also many drivers will stay loaded afterward, bloating the output
+of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
+loaded as a dependency) can't even be unloaded!
+
+If defining char-major-10-130 is needed then it should happen in
+user-space.

++Xilinx plb/axi GPIO controller
++
++Dual channel GPIO controller with configurable number of pins
++(from 1 to 32 per channel). Every pin can be configured as
++input/output/tristate. Both channels share the same global IRQ but
++local interrupts can be enabled on channel basis.
++
++Required properties:
++- compatible : Should be "xlnx,xps-gpio-1.00.a"
++- reg : Address and length of the register set for the device
++- #gpio-cells : Should be two. The first cell is the pin number and the
++ second cell is used to specify optional parameters (currently unused).
++- gpio-controller : Marks the device node as a GPIO controller.
++
++Optional properties:
++- interrupts : Interrupt mapping for GPIO IRQ.
++- interrupt-parent : Phandle for the interrupt controller that
++ services interrupts for this device.
++- xlnx,all-inputs : if n-th bit is setup, GPIO-n is input
++- xlnx,dout-default : if n-th bit is 1, GPIO-n default value is 1
++- xlnx,gpio-width : gpio width
++- xlnx,tri-default : if n-th bit is 1, GPIO-n is in tristate mode
++- xlnx,is-dual : if 1, controller also uses the second channel
++- xlnx,all-inputs-2 : as above but for the second channel
++- xlnx,dout-default-2 : as above but the second channel
++- xlnx,gpio2-width : as above but for the second channel

+Subject: USB: host: use platform_{get,set}_drvdata()
+
+Use the wrapper functions for getting and setting the driver data using
+platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
+so we can directly pass a struct platform_device.
+
+Also, unnecessary dev_set_drvdata() is removed, because the driver core
+clears the driver data to NULL after device_release or on probe failure.

+Subject: drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to
+ dma_zalloc_coherent
+
+__GFP_ZERO is an uncommon flag and perhaps is better
+not used. static inline dma_zalloc_coherent exists
+so convert the uses of dma_alloc_coherent with __GFP_ZERO
+to the more common kernel style with zalloc.
+
+Remove memset from the static inline dma_zalloc_coherent
+and add just one use of __GFP_ZERO instead.
+
+Trivially reduces the size of the existing uses of
+dma_zalloc_coherent.
+
+Realign arguments as appropriate.

+Subject: video: xilinxfb: replace devm_request_and_ioremap by
+ devm_ioremap_resource
+
+Use devm_ioremap_resource instead of devm_request_and_ioremap.
+
+This was done using the semantic patch
+scripts/coccinelle/api/devm_ioremap_resource.cocci
+
+The initialization of drvdata->regs_phys was manually moved lower, to take
+advantage of the NULL test on res performed by devm_ioremap_resource.

+Subject: i2c: move OF helpers into the core
+
+I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
+that it is much cleaner to have this in the core. This also removes a
+circular dependency between the helpers and the core, and so we can
+finally register child nodes in the core instead of doing this manually
+in each driver. So, fix the drivers and documentation, too.

+guaranteed by the C programming language.
