commit c61d7b2ef141abf81140756b45860a2306f395a2 upstream. Currently the documentation states that channels must be configured before running the dmatest. This has not been true since commit 6b41030fdc79 ("dmaengine: dmatest: Restore default for channel"). Fix accordingly.

commit 95364f36701e62dd50eee91e1303187fd1a9f567 upstream. In case a driver wants to return an error from qc_prep, return enum ata_completion_errors. sata_mv is one of those drivers -- see the next patch. Other drivers return the newly defined AC_ERR_OK. [v2] use enum ata_completion_errors and AC_ERR_OK.

Other than that churn, there are two "persistent" branches in here that other trees will be pulling in as well during the merge window.

2019-08-15gpio: Add support for hierarchical IRQ domainsLinus Walleij
Hierarchical IRQ domains can be used to stack different IRQ controllers on top of each other. Bring hierarchical IRQ domains into the GPIOLIB core with the following basic idea: Drivers that need their interrupts handled hierarchically specify a callback to translate the child hardware IRQ and IRQ type for each GPIO offset to a parent hardware IRQ and parent hardware IRQ type. Users have to pass the callback, fwnode, and parent irqdomain before calling gpiochip_irqchip_add(). We use the new method of just filling in the struct gpio_irq_chip before adding the gpiochip for all hierarchical irqchips of this type. The code path for device tree is pretty straight-forward, while the code path for old boardfiles or anything else will be more convoluted requireing upfront allocation of the interrupts when adding the chip. One specific use-case where this can be useful is if a power management controller has top-level controls for wakeup interrupts. In such cases, the power management controller can be a parent to other interrupt controllers and program additional registers when an IRQ has its wake capability enabled or disabled. The hierarchical irqchip helper code will only be available when IRQ_DOMAIN_HIERARCHY is selected to GPIO chips using this should select or depend on that symbol. When using hierarchical IRQs, the parent interrupt controller must also be hierarchical all the way up to the top interrupt controller wireing directly into the CPU, so on systems that do not have this we can get rid of all the extra code for supporting hierarchical irqs.

2019-07-25driver core: Remove device link creation limitationRafael J. Wysocki
If device_link_add() is called for a consumer/supplier pair with an existing device link between them and the existing link's type is not in agreement with the flags passed to that function by its caller, NULL will be returned. That is seriously inconvenient, because it forces the callers of device_link_add() to worry about what others may or may not do even if that is not relevant to them for any other reasons. It turns out, however, that this limitation can be made go away relatively easily. The underlying observation is that if DL_FLAG_STATELESS has been passed to device_link_add() in flags for the given consumer/supplier pair at least once, calling either device_link_del() or device_link_remove() to release the link returned by it should work, but there are no other requirements associated with that flag. In turn, if at least one of the callers of device_link_add() for the given consumer/supplier pair has not passed DL_FLAG_STATELESS to it in flags, the driver core should track the status of the link and act on it as appropriate (ie. the link should be treated as "managed"). This means that DL_FLAG_STATELESS needs to be set for managed device links and it should be valid to call device_link_del() or device_link_remove() to drop references to them in certain sutiations. To allow that to happen, introduce a new (internal) device link flag called DL_FLAG_MANAGED and make device_link_add() set it automatically whenever DL_FLAG_STATELESS is not passed to it. Also make it take additional references to existing device links that were previously stateless (that is, with DL_FLAG_STATELESS set and DL_FLAG_MANAGED unset) and will need to be managed going forward and initialize their status (which has been DL_STATE_NONE so far). Accordingly, when a managed device link is dropped automatically by the driver core, make it clear DL_FLAG_MANAGED, reset the link's status back to DL_STATE_NONE and drop the reference to it associated with DL_FLAG_MANAGED instead of just deleting it right away (to allow it to stay around in case it still needs to be released explicitly by someone). With that, since setting DL_FLAG_STATELESS doesn't mean that the device link in question is not managed any more, replace all of the status-tracking checks against DL_FLAG_STATELESS with analogous checks against DL_FLAG_MANAGED and update the documentation to reflect these changes. While at it, make device_link_add() reject flags that it does not recognize, including DL_FLAG_MANAGED. Signed-off-by: Rafael J.

The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features. Core: - Add a 'clk_parent' file in clk debugfs - Add a clk_bulk_get_optional() API (with devm too) New Drivers: - Support gated clk controller on MIPS based BCM63XX SoCs - Support SiLabs Si5341 and Si5340 chips - Support for CPU clks on Raspberry Pi devices - Audsys clock driver for MediaTek MT8516 SoCs Updates: - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme - Small frequency support for SiLabs Si544 chips - Slow clk support for AT91 SAM9X60 SoCs - Remove dead code in various clk drivers (-Wunused) - Support for Marvell 98DX1135 SoCs - Get duty cycle of generic pwm clks - Improvement in mmc phase calculation and cleanup of some rate defintions - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs - Add GPIO, SNVS and GIC clocks for i.MX8 drivers - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting - Add clks for new Exynos5422 Dynamic Memory Controller driver - Clock definition for Exynos4412 Mali - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3 - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs - TI clock probing done from DT by default instead of firmware - Fix Amlogic Meson mpll fractional part and spread sprectrum issues - Add Amlogic meson8 audio clocks - Add Amlogic g12a temperature sensors clocks - Add Amlogic g12a and g12b cpu clocks - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W - Add Clock Domain support on Renesas RZ/N1" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (190 commits) clk: consoldiate the __clk_get_hw() declarations clk: sprd: Add check for return value of sprd_clk_regmap_init() clk: lochnagar: Update DT binding doc to include the primary SPDIF MCLK clk: Add Si5341/Si5340 driver dt-bindings: clock: Add silabs,si5341 clk: clk-si544: Implement small frequency change support clk: add BCM63XX gated clock controller driver devicetree: document the BCM63XX gated clock bindings clk: at91: sckc: use dedicated functions to unregister clock clk: at91: sckc: improve error path for sama5d4 sck registration clk: at91: sckc: remove unnecessary line clk: at91: sckc: improve error path for sam9x5 sck register clk: at91: sckc: add support to free slow clock osclillator clk: at91: sckc: add support to free slow rc oscillator clk: at91: sckc: add support to free slow oscillator clk: rockchip: export HDMIPHY clock on rk3228 clk: rockchip: add watchdog pclk on rk3328 clk: rockchip: add clock id for hdmi_phy special clock on rk3228 clk: rockchip: add clock id for watchdog pclk on rk3328 clk: at91: sckc: add support for SAM9X60 ...
