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.

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.

2017-04-18sysreset: psci: support system reset in a generic way with PSCIMasahiro Yamada
If the system is running PSCI firmware, the System Reset function (func ID: 0x80000009) is supposed to be handled by PSCI, that is, the SoC/board specific reset implementation should be moved to PSCI. U-Boot should call the PSCI service according to the arm-smccc manner. The arm-smccc is supported on ARMv7 or later. Especially, ARMv8 generation SoCs are likely to run ARM Trusted Firmware BL31. In this case, U-Boot is a non-secure world boot loader, so it should not be able to reset the system directly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-11-28linux/compat.h: Properly implement ndelay fallbackmario.six@gdsys.cc
Commit c68c62 ("i2c: mvtwsi: Make delay times frequency-dependent") extensively used the ndelay function with a calculated parameter which is dependant on the configured frequency of the I2C bus. If standard speed is employed, the parameter is usually 10000 (10000ns period length for 100kHz frequency). But, since the arm architecture does not implement a proper version of ndelay, the fallback default from include/linux/compat.h is used, which defines every ndelay as udelay(1). This causes problems for slower speeds on arm, since the delay time is now 9us too short for the desired frequency, which leads to random failures of the I2C interface. To remedy this, we implement a proper, parameter-aware ndelay fallback for architectures that don't implement a real ndelay function.
