2021-09-28mtd: nand: raw: convert nand_dt_init() to ofnode_xx() interfacePatrice Chotard
nand_dt_init() is still using fdtdec_xx() interface. If OF_LIVE flag is enabled, dt property can't be get anymore. Updating all fdtdec_xx() interface to ofnode_xx() to solve this issue. For doing this, node parameter type must be ofnode. First idea was to convert "node" parameter to ofnode type inside nand_dt_init() using offset_to_ofnode(node). But offset_to_ofnode() is not bijective, in case OF_LIVE flag is enabled, it performs an assert(). So, this leads to update nand_chip struct flash_node field from int to ofnode and to update all nand_dt_init() callers. Signed-off-by: Patrice Chotard <[email protected]>
2021-09-28mtd: spi: nor: force mtd name to "nor%d"Patrick Delaunay
Force the mtd name of spi-nor to "nor" + the driver sequence number: "nor0", "nor1"... beginning after the existing nor devices. This patch is coherent with existing "nand" and "spi-nand" mtd device names. When CFI MTD NOR device are supported, the spi-nor index is chosen after the last CFI device defined by CONFIG_SYS_MAX_FLASH_BANKS. When CONFIG_SYS_MAX_FLASH_BANKS_DETECT is activated, this config is replaced by to cfi_flash_num_flash_banks in the include file mtd/cfi_flash.h. This generic name "nor%d" can be use to identify the mtd spi-nor device without knowing the real device name or the DT path of the device, used with API get_mtd_device_nm() and is used in mtdparts command. This patch also avoids issue when the same NOR device is present 2 times, for example on STM32MP15F-EV1: STM32MP> mtd list SF: Detected mx66l51235l with page size 256 Bytes, erase size 64 KiB, \ total 64 MiB List of MTD devices: * nand0 - type: NAND flash - block size: 0x40000 bytes - min I/O: 0x1000 bytes - OOB size: 224 bytes - OOB available: 118 bytes - ECC strength: 8 bits - ECC step size: 512 bytes - bitflip threshold: 6 bits - 0x000000000000-0x000040000000 : "nand0" * mx66l51235l - device: mx66l51235l@0 - parent: spi@58003000 - driver: jedec_spi_nor - path: /soc/spi@58003000/mx66l51235l@0 - type: NOR flash - block size: 0x10000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000004000000 : "mx66l51235l" * mx66l51235l - device: mx66l51235l@1 - parent: spi@58003000 - driver: jedec_spi_nor - path: /soc/spi@58003000/mx66l51235l@1 - type: NOR flash - block size: 0x10000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000004000000 : "mx66l51235l" The same mtd name "mx66l51235l" identify the 2 instances mx66l51235l@0 and mx66l51235l@1.

2021-07-01build_bug.h: add wrapper for _Static_assertRasmus Villemoes
[Linux commit 6bab69c65013bed5fce9f101a64a84d0385b3946] BUILD_BUG_ON() is a little annoying, since it cannot be used outside function scope. So one cannot put assertions about the sizeof() a struct next to the struct definition, but has to hide that in some more or less arbitrary function. Since gcc 4.6 (which is now also the required minimum), there is support for the C11 _Static_assert in all C modes, including gnu89. So add a simple wrapper for that. _Static_assert() requires a message argument, which is usually quite redundant (and I believe that bug got fixed at least in newer C++ standards), but we can easily work around that with a little macro magic, making it optional. For example, adding static_assert(sizeof(struct printf_spec) == 8); in vsprintf.c and modifying that struct to violate it, one gets ./include/linux/build_bug.h:78:41: error: static assertion failed: "sizeof(struct printf_spec) == 8" #define __static_assert(expr, msg, ...) _Static_assert(expr, "" msg "") godbolt.org suggests that _Static_assert() has been support by clang since at least 3.0.0.

2021-06-28mtd: spi-nor-core: Perform a Soft Reset on shutdownPratyush Yadav
On probe, the SPI NOR core will put a flash in 8D-8D-8D mode if it supports it. But Linux as of now expects to get the flash in 1S-1S-1S mode. Handing the flash to Linux in Octal DTR mode means the kernel will fail to detect the flash. So, we need to reset to Power-on-Reset (POR) state before handing off the flash. A Software Reset command can be used to do this. One limitation of the soft reset is that it will restore state from non-volatile registers in some flashes. This means that if the flash was set to 8D mode in a non-volatile configuration, a soft reset won't help. This commit assumes that we don't set any non-volatile bits anywhere, and the flash doesn't have any non-volatile Octal DTR mode configuration. Since spi-nor-tiny doesn't (and likely shouldn't) have spi_nor_soft_reset(), add a dummy spi_nor_remove() for it that does nothing.

2021-06-28mtd: spi-nor-core: Rework hwcaps selectionPratyush Yadav
The spi-mem layer provides a spi_mem_supports_op() function to check whether a specific operation is supported by the controller or not. This is much more accurate than the hwcaps selection logic based on SPI_{RX,TX}_ flags. Rework the hwcaps selection logic to use spi_mem_supports_op(). To make sure the build doesn't break for boards not using CONFIG_DM_SPI, add a simple SPI_{RX,TX}_ based hwcaps selection logic in spi-mem-nodm similar to spi_mem_default_supports_op(). This change is only compile-tested. To avoid SPL size problems on the x530 board, the old hwcaps selection is still kept around. Leaving the code in-place was getting difficult to read and understand, so the code is restructured to have it all in one isolated function. As a result of this, the parameter hwcaps to spi_nor_setup() is no longer needed. Remove it.

2021-06-28mtd: spi-nor-core: Introduce flash-specific fixup hooksPratyush Yadav
Sometimes the information in a flash's SFDP tables is wrong. Sometimes some information just can't be expressed in the SFDP table. So, introduce the fixup hooks to allow tailoring settings for a specific flash. Three hooks are added: default_init, post_sfdp, and post_bfpt. These allow tweaking the flash settings at different point in the probe sequence. Since the hooks reside in nor->info, set that value just before the call to spi_nor_init_params(). The hooks and at what points they are executed mimics Linux's spi-nor framework. One major difference is that Linux puts the struct spi_nor_fixups in nor->info. This is not possible in U-Boot because the spi-nor-ids list is shared between spi-nor-core.c and spi-nor-tiny.c. Since spi-nor-tiny shouldn't have those fixup hooks populated, add a separate function that lets flashes populate their fixup hooks.

This is a proting patch from linux kernel: 37a3a533429e ("usb: gadget: OS Feature Descriptors support"), the original commit log see below: There is a custom (non-USB IF) extension to the USB standard: http://msdn.microsoft.com/library/windows/hardware/gg463182 They grant permission to use the specification - there is "Microsoft OS Descriptor Specification License Agreement" under the link mentioned above, and its Section 2 "Grant of License", letter (b) reads: "Patent license. Microsoft hereby grants to You a nonexclusive, royalty-free, nontransferable, worldwide license under Microsoft鈥檚 patents embodied solely within the Specification and that are owned or licensable by Microsoft to make, use, import, offer to sell, sell and distribute directly or indirectly to Your Licensees Your Implementation. You may sublicense this patent license to Your Licensees under the same terms and conditions." The said extension is maintained by Microsoft for Microsoft. Yet it is fairly common for various devices to use it, and a popular proprietary operating system expects devices to provide "OS descriptors", so Linux-based USB gadgets whishing to be able to talk to a variety of operating systems should be able to provide the "OS descriptors". This patch adds optional support for gadgets whishing to expose the so called "OS Feature Descriptors", that is "Extended Compatibility ID" and "Extended Properties". Hosts which do request "OS descriptors" from gadgets do so during the enumeration phase and before the configuration is set with SET_CONFIGURATION. What is more, those hosts never ask for configurations at indices other than 0. Therefore, gadgets whishing to provide "OS descriptors" must designate one configuration to be used with this kind of hosts - this is what os_desc_config is added for in struct usb_composite_dev. There is an additional advantage to it: if a gadget provides "OS descriptors" and designates one configuration to be used with such non-USB-compliant hosts it can invoke "usb_add_config" in any order because the designated configuration will be reported to be at index 0 anyway. This patch also adds handling vendor-specific requests addressed at device or interface and related to handling "OS descriptors"."

2021-01-31usb: gadget: OS String supportLi Jun
This is a porting patch from linux kernel: 19824d5eeece ("usb: gadget: OS String support"), original commit log see below: "There is a custom (non-USB IF) extension to the USB standard: http://msdn.microsoft.com/library/windows/hardware/gg463182 They grant permission to use the specification - there is "Microsoft OS Descriptor Specification License Agreement" under the link mentioned above, and its Section 2 "Grant of License", letter (b) reads: "Patent license. Microsoft hereby grants to You a nonexclusive, royalty-free, nontransferable, worldwide license under Microsoft鈥檚 patents embodied solely within the Specification and that are owned or licensable by Microsoft to make, use, import, offer to sell, sell and distribute directly or indirectly to Your Licensees Your Implementation. You may sublicense this patent license to Your Licensees under the same terms and conditions." The said extension is maintained by Microsoft for Microsoft. Yet it is fairly common for various devices to use it, and a popular proprietary operating system expects devices to provide "OS descriptors", so Linux-based USB gadgets whishing to be able to talk to a variety of operating systems should be able to provide the "OS descriptors". This patch adds optional support for gadgets whishing to expose the so called "OS String" under index 0xEE of language 0. The contents of the string is generated based on the qw_sign array and b_vendor_code. Interested gadgets need to set the cdev->use_os_string flag, fill cdev->qw_sign with appropriate values and fill cdev->b_vendor_code with a value of their choice. This patch does not however implement responding to any vendor-specific USB requests." Signed-off-by: Li Jun <[email protected]> Signed-off-by: Peng Fan <[email protected]>
2021-01-31usb: gadget: Add ep_config call back to usb_gadget_opsYe Li
Since some new fields in usb_ep structure been moved to usb_ss_ep. The CDNS3 gadget driver should replies on this operation to bind the usb_ss_ep with the endpoint descriptor when function layer uses usb_ep_autoconfig to add endpoint descriptors to gadget. So that CDNS3 driver can know the EP information and configure the EP once the set configuration request is received.

2021-01-27smccc: fix sign bit expansionVolodymyr Babchuk
Signed ARM_SMCCC_FAST_CALL value is shifted to 31'st bit. Then, it is expanded to 64 bit value, which results in 1s in higher 32 bits. This causes corrupted values in 64-bit SMC IDs and issues in buggy handlers of 32-bit calls. We need to make ARM_SMCCC_FAST_CALL unsigned long, so it would work properly on 32 bit architectures.
