2022-01-23Merge tag 'samsung-pinctrl-5.18' of https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into for-v5.18/dt-pinctrlKrzysztof Kozlowski9-405/+704
Samsung pinctrl drivers changes for v5.18 1. Fix OF reference leak in pinctrl driver probe error path. 2. Correct list of handlers for Exynos850 ALIVE and CMGP pin banks. 3. Accept devicetrees with GPIO pin bank definitions named with a "-gpio-bank" suffix. This is necessary for later Samsung pinctrl bindings dtschema. 4. Convert Samsung pinctrl bindings to dtschema. 5. Add support for Exynos850 and ExynosAutov9 wake-up interrupts. This merge is necessary to apply DTS cleanup patches, which in turn silences any warnings from newly introduced dtschema for Samsung pinctrl driver. The merge brings driver changes and mentioned dtschema. The driver change is the dependency for follow-up DTS patches which rename GPIO bank nodes. With the change in DTS files, the new schema passes without errors.

2022-01-23block: fix memory leak in disk_register_independent_access_rangesMiaoqian Lin1-1/+1
kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add() If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Fix this issue by adding kobject_put(). Callback function blk_ia_ranges_sysfs_release() in kobject_put() can handle the pointer "iars" properly.

2022-01-23io_uring: fix bug in slow unregistering of nodesDylan Yudaken1-1/+6
In some cases io_rsrc_ref_quiesce will call io_rsrc_node_switch_start, and then immediately flush the delayed work queue &ctx->rsrc_put_work. However the percpu_ref_put does not immediately destroy the node, it will be called asynchronously via RCU. That ends up with io_rsrc_node_ref_zero only being called after rsrc_put_work has been flushed, and so the process ends up sleeping for 1 second unnecessarily. This patch executes the put code immediately if we are busy quiescing.

In the i.MX28 manual (MCIMX28RM, Rev. 1, 2010) you can find an example (15.2.4 High-Speed NAND Timing) of how to configure the GPMI controller to manage High-Speed ​​NAND devices, so it was wrong to assume that only i.MX6 can achieve EDO timings.

2022-01-23mtd: rawnand: gpmi: validate controller clock rateDario Binacchi1-4/+18
What to do when the real rate of the gpmi clock is not equal to the required one? The solutions proposed in [1] did not lead to a conclusion on how to validate the clock rate, so, inspired by the document [2], I consider the rate correct only if not lower or equal to the rate of the previous edo mode. In fact, in chapter 4.16.2 (NV-DDR) of the document [2], it is written that "If the host selects timing mode n, then its clock period shall be faster than the clock period of timing mode n-1 and slower than or equal to the clock period of timing mode n.". I thought that it could therefore also be used in this case, without therefore having to define the valid rate ranges empirically. For example, suppose that gpmi_nfc_compute_timings() is called to set edo mode 5 (100MHz) but the rate returned by clk_round_rate() is 80MHz (edo mode 4). In this case gpmi_nfc_compute_timings() will return error, and will be called again to set edo mode 4, which this time will be successful.

2022-01-23mtd: rawnand: gpmi: fix controller timings settingDario Binacchi1-0/+3
Set the controller registers according to the real clock rate. The controller registers configuration (setup, hold, timeout, ... cycles) depends on the clock rate of the GPMI. Using the real rate instead of the ideal one, avoids that this inaccuracy (required_rate - real_rate) affects the registers setting. This patch has been tested on two custom boards with i.MX28 and i.MX6 SOCs: - i.MX28: required rate 100MHz, real rate 99.3MHz - i.MX6 required rate 100MHz, real rate 99MHz Fixes: b1206122069a ("mtd: rawnand: gpmi: use core timings instead of an empirical derivation") Co-developed-by: Michael Trimarchi <michael@amarulasolutions.com> Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com> Tested-by: Sascha Hauer <s.hauer@pengutronix.de> Reviewed-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20220118095434.35081-3-dario.binacchi@amarulasolutions.com

Add a BCMA shim to allow us to register the brcmnand driver using the BCMA bus which provides indirect memory mapped access to SoC registers. There are a number of registers that need to be byte swapped because they are natively big endian, coming directly from the NAND chip, and there is no bus interface unlike the iProc or STB platforms that performs the byte swapping for us.

Commit b18c6c3c7768 ("ASoC: rockchip: cdn-dp sound output use spdif") switched the platform to SPDIF, but we didn't fix up the device tree. Drop the pinctrl settings, because the 'spdif_bus' pins are either: * unused (on kevin, bob), so the settings is ~harmless * used by a different function (on scarlet), which causes probe failures (!!)

The micro USB3.0 port available on the Haikou evaluation kit for Puma RK3399-Q7 SoM supports dual-role model (aka drd or OTG) but its support was broken until now because of missing logic around the ID pin. This adds proper support for USB OTG on Puma Haikou by "connecting" the GPIO used for USB ID to the USB3 controller device.

The previous commit 4b402fa8e0b7 ("phy: phy-brcm-usb: support PHY on the BCM4908") added a second "default" line for ARCH_BCM_4908 above the original "default" line for ARCH_BRCMSTB. When two "default" lines are used, only the first is used and this change stopped the PHY_BRCM_USB option for being enabled for ARCH_BRCMSTB. The fix is to use one "default line with "||".

2022-01-23phy: usb: Leave some clocks running during suspendAl Cooper1-0/+38
The PHY client driver does a phy_exit() call on suspend or rmmod and the PHY driver needs to know the difference because some clocks need to be kept running for suspend but can be shutdown on unbind/rmmod (or if there are no PHY clients at all). The fix is to use a PM notifier so the driver can tell if a PHY client is calling exit() because of a system suspend or a driver unbind/rmmod.
