2018-06-13MLK-18376-3 usb: gadget: OS Feature Descriptors supportLi Jun
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’s 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"."

2018-04-27MLK-17821-1 USB: gadget: Add the cadence USB3 gadget driverYe Li
Porting the cadence USB3 (CDNS3) driver from kernel to u-boot. We only support the gadget (device mode), while the host mode is not supported. Users remains to use xhci-imx8 driver for host mode. Some changes in the CDNS3 driver porting: 1. Add match_ep call back to usb_gadget_ops. The CDNS3 gadget driver replies on this operation to bind the usb_ep/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. 2. U-boot does not have CMA, so it won't allocate uncached memory. Need to flush TRB and its DMA buffer before prime to usb controller and after complete transfer. 3. In core.c, we add functions to hook with u-boot. It needs uplayer like to pass the register base address of each part of the USB controller. 4. Force the CDNS3 gadget max speed to HS. The SuperSpeed is not supported by u-boot, so disable it in gadget driver. A configuration USB_CDNS3_GADGET_FORCE_HIGHSPEED is selected. 5. Added gadget_is_cdns3 checking to provide bcdUSB value in device descriptor. 6. Moved some new fields in usb_ep structure to usb_ss_ep, since u-boot does not have them. 7. Remove host part codes as it is not supported by this driver.

2017-11-29mtd: nand: introduce NAND_ROW_ADDR_3 flagMasahiro Yamada
Several drivers check ->chipsize to see if the third row address cycle is needed. Instead of embedding magic sizes such as 32MB, 128MB in drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up. Since nand_scan_ident() knows well about the device, it can handle this properly. The flag is set if the row address bit width is greater than 16. Delete comments such as "One more address cycle for ..." because intention is now clear enough from the code.

2017-11-29mtd: nand: add a shorthand to generate nand_ecc_caps structureMasahiro Yamada
struct nand_ecc_caps was designed as flexible as possible to support multiple stepsizes (like sunxi_nand.c). So, we need to write multiple arrays even for the simplest case. I guess many controllers support a single stepsize, so here is a shorthand macro for the case. It allows to describe like ... NAND_ECC_CAPS_SINGLE(denali_pci_ecc_caps, denali_calc_ecc_bytes, 512, 8, 15); ... instead of static const int denali_pci_ecc_strengths[] = {8, 15}; static const struct nand_ecc_step_info denali_pci_ecc_stepinfo = { .stepsize = 512, .strengths = denali_pci_ecc_strengths, .nstrengths = ARRAY_SIZE(denali_pci_ecc_strengths), }; static const struct nand_ecc_caps denali_pci_ecc_caps = { .stepinfos = &denali_pci_ecc_stepinfo, .nstepinfos = 1, .calc_ecc_bytes = denali_calc_ecc_bytes, }; Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> [Linux commit: a03c60178c181767ecfb26fb311a88742d228118]
2017-11-29mtd: nand: add generic helpers to check, match, maximize ECC settingsMasahiro Yamada
Driver are responsible for setting up ECC parameters correctly. Those include: - Check if ECC parameters specified (usually by DT) are valid - Meet the chip's ECC requirement - Maximize ECC strength if NAND_ECC_MAXIMIZE flag is set The logic can be generalized by factoring out common code. This commit adds 3 helpers to the NAND framework: nand_check_ecc_caps - Check if preset step_size and strength are valid nand_match_ecc_req - Match the chip's requirement nand_maximize_ecc - Maximize the ECC strength To use the helpers above, a driver needs to provide: - Data array of supported ECC step size and strength - A hook that calculates ECC bytes from the combination of step_size and strength. By using those helpers, code duplication among drivers will be reduced.

2017-11-29mtd: nand: automate NAND timings selectionBoris Brezillon
The NAND framework provides several helpers to query timing modes supported by a NAND chip, but this implies that all NAND controller drivers have to implement the same timings selection dance. Also currently NAND devices can be resetted at arbitrary places which also resets the timing for ONFI chips to timing mode 0. Provide a common logic to select the best timings based on ONFI or ->onfi_timing_mode_default information. Hook this into nand_reset() to make sure the new timing is applied each time during a reset. NAND controller willing to support timings adjustment should just implement the ->setup_data_interface() method.

2017-11-29mtd: nand: Add an option to maximize the ECC strengthBoris Brezillon
The generic NAND DT bindings allows one to tweak the ECC strength and step size to their need. It can be used to lower the ECC strength to match a bootloader/firmware config, but might also be used to get a better reliability. In the latter case, the user might want to use the maximum ECC strength without having to explicitly calculate the exact value (this value not only depends on the OOB size, but also on the NAND controller, and can be tricky to extract). Add a generic 'nand-ecc-maximize' DT property and the associated NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best ECC strength and step-size on their own.

2017-10-04dm: define dev_*() log functions in DM headerMasahiro Yamada
Many drivers had started to use dev_err, dev_info, etc. for log functions. Currently, we are relying on <linux/compat.h>, but I guess the best home is <dm/device.h>, taking into account that Linux defines them in <linux/device.h>. For now, I am leaving the ones in <linux/compat.h> because lots of Linux-originated code uses dev_*(), but the first argument is not struct udevice, so we need to ignore the bogus argument. More efforts are needed to iron out the issues. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-10-04bug.h: sync BUILD_BUG stuff with Linux 4.13Masahiro Yamada
As commit 84b8bf6d5d2a ("bug.h: move BUILD_BUG_* defines to include/linux/bug.h") noted, include/linux/bug.h was locally modified for U-Boot because the name conflict of error() caused build errors at that time. Now error() is gone, so we can fully sync BUILD_BUG* with Linux. These macros are just compile-time utilities. Nothing depends on platform code, so it should make sense to simply copy Linux's ones. Please note Linux split BUILD_BUG stuff out into <linux/build_bug.h> by commit bc6245e5efd7. Let's follow it. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-10-04printk: collect printk stuff into <linux/printk.h> with loglevel supportMasahiro Yamada
When we import code from Linux, with regular re-sync planned, we want to use printk() and pr_*(). U-Boot does not support them in a clean way. So, people end up with local macros, or compat headers here and there, then we occasionally see build errors of definition conflicts. We have include/linux/compat.h, but putting all sorts of unrelated things into a single header is just a temporal workaround. Hence this patch, to find the best home for all printk variants. If you want to use printk() and friends, please include <linux/printk.h>. This header is self-contained, and pulls in only a few headers. When I was testing this clean-up, I noticed the image size exceeded its platform limit on some boards. This is because all pr_*() that were previously defined as no-op in include/linux/mtd/mtd.h (unless CONFIG_MTD_DEBUG is set), are now enabled. To make such boards happy, this commit also implements CONFIG_LOGLEVEL. The concept is similar to the kernel parameter "loglevel". (Actually, the Kconfig help message was taken from kernel-paremeter.txt of Linux) Messages with a loglevel smaller than console loglevel will be printed. The difference is the loglevel is build-time determined. To save the image size, lower priority pr_*() are compiled out. I set the default of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages are compiled in. I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

2017-10-01usb: xhci: Honor endpoint's intervalBin Meng
USB endpoint reports the period between consecutive requests to send or receive data as bInverval in its endpoint descriptor. So far this is ignored by xHCI driver and the 'Interval' field in xHC's endpoint context is always programmed to zero which means 1ms for low speed or full speed , or 125us for high speed or super speed. We should honor the interval by getting it from endpoint descriptor. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

2017-08-13spl: dm: use CONFIG_IS_ENABLED to test for the DM optionPhilipp Tomsich
Even though there's now a TPL_DM configuration option, the spl logic still checks for SPL_DM and thus does not pick up the proper config option. This introduces the use of CONFIG_IS_ENABLED(DM) in spl.c to always pick up the desired configuration option instead of having a hard-coded check for the SPL variant.

AVR32 is gone. It's already more than two years for no support in Buildroot, even longer there is no support in GCC (last version is heavily patched 4.2.4). Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully). There is no good point to keep this support in U-Boot either.
