drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C library. But there is a problem. The specification of tcdrain() requires that it be a cancellation point. In order to do this, tcdrain was moved from the C library into the OS and the addition cancellation point hooks were added. In non-FLAT builds, access via system calls is also now supported.

Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().
...
Squashed commit of the following:
Change all calls to usleep() in the OS proper to calls to nxsig_usleep()
sched/signal: Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.
sched/signal: Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

sched/semaphore: sem_timedwait() is a cancellation point and, hence, cannot be called from within the OS. Created nxsem_timedwait() that is equivalent but does not modify the errno and does not cause cancellation. All calls to sem_timedwait() change to calls to nxsem_timedwait() in the OS.

STM32L4 RTC, PM: small fixes to subseconds handling, ADC power-management hooks
* STM32L4 ADC: add PM hooks from Motorola MDK
* STM32L4 RTC: add up_rtc_getdatetime_with_subseconds
* STM32 RTC: workaround for potential subseconds race condition
In all recent STM32 chips reading either RTC_SSR or RTC_TR is supposed to lock
the values in the higher-order calendar shadow registers until RTC_DR is read.
However many old chips have in their errata this silicon bug (at least F401xB/C,
F42xx, F43xx, L15xxE, L15xVD and likely others):
"When reading the calendar registers with BYPSHAD=0, the RTC_TR and RTC_DR
registers may not be locked after reading the RTC_SSR register. This happens
if the read operation is initiated one APB clock period before the shadow
registers are updated. This can result in a non-consistency of the three
registers. Similarly, RTC_DR register can be updated after reading the RTC_TR
register instead of being locked."
* STM32L4 RTC: correct RTC_SSR and RTC_TR read ordering
In all recent STM32 chips reading either RTC_SSR or RTC_TR is supposed to lock
the values in the higher-order calendar shadow registers until RTC_DR is read.
Change the register read ordering to match this and don't keep a workaround
for a hypothetical race condition (not in any L4 errata, lets for once assume
ST's silicon works as it is documented...)

commit b2ea300b6f broke the STM32L4 port for people not using the L496xx or L4A6xx. That was because stm32l4_sdmmc.h is included from the stm32l4.h global header, and this header fires an #error for other chips. I see that ALL stm32l4 have the same SDMMC except the stm32l4x2, which has none.

I discovered while working on the SAMV7 mcan driver that the implementation of the CAN error handling is suboptimal. In the current implementation the following errors are implemented as pending errors:
...
* Receiving
* MCAN_INT_STE (Stuff Error)
More than 5 equal bits in a sequence occurred.
* MCAN_INT_CRCE (CRC Error)
Received CRC did not match the calculated CRC.
* MCAN_INT_RF0L (Receive FIFO 0 Message Lost)
Receive FIFO 0 message lost, also set after write attempt to Receive FIFO 0 of size zero.
* MCAN_INT_RF1L (Receive FIFO 1 Message Lost)
Receive FIFO 1 message lost, also set after write attempt to Receive FIFO 1 of size zero.
* Sending
* MCAN_INT_BE (Bit Error)
Device wanted to send a rec / dom level, but monitored bus level was dominant / recessive.
* MCAN_INT_TEFL (Tx Event FIFO Element Lost)
Tx Event FIFO element lost, also set after write attempt to Tx Event FIFO of size zero.
* General
* MCAN_INT_MRAF (Message RAM Access Failure)
The flag is set, when the Rx Handler
* has not completed acceptance filtering or storage of an accepted message until the arbitration field of the following message has been received. In this case acceptance filtering or message storage is aborted and the Rx Handler starts processing of the following message.
* was not able to write a message to the Message RAM. In this case message storage is aborted. In both cases the FIFO put index is not updated resp. the New Data flag for a dedicated Receive Buffer is not set, a partly stored message is overwritten when the next message is stored to this location. The flag is also set when the Tx Handler was not able to read a message from the Message RAM in time. In this case message transmission is aborted. In case of a Tx Handler access failure the MCAN is switched into Restricted Operation mode (see Section 47.5.1.5). To leave Restricted Operation mode, the processor has to reset MCAN_CCCR.ASM.
* MCAN_INT_ELO (Error Logging Overflow)
Overflow of CAN Error Logging Counter occurred.
The listed errors are not pending, the errors occurred and are gone directly afterwards. This commit changes the described behavior and simplifies the handling of CAN errors.

I'm working on bringing up USB full-speed support on STM32F405. My board does not include a USB power switch, VBus sensing, over current detection, or ID pin.
...
This commit add a config STM32_OTGFS_VBUS_ CONTROL which lets us selectively disable VBus sensing and control. I also sneaked in a change to disable the configgpio call for the ID pin, which is only used in OTG mode which isn't supported yet. The only pins that need to be initialized should be OTGFS_DP and OTGFS_DM.
These changes let a USB mouse enumerate on my platform if it's plugged in on power-up. Plugging, unplugging, clicking, or moving the mouse cause NSH to stop responding. Because I'm using the ramlog, I don't have useful debug messaging yet, so there's a lot more work I have to do to troubleshoot it or get my JTAG debugging set up, but these patches shouldn't hurt anything. I'm hoping my issue is something simple I overlooked in configuration.
I'm planning to add similar changes for the OTGHS peripheral (using integrated full speed phy) but I still need to test those changes before submitting patches.

To use an external oscillator module (not just a crystal) with the STM32F4, one needs to enable the HSEBYP bit in the RCC_CR register. This change allows an integrator to define STM32_RCC_CR_HSEBYP in their board.h file if they want this configuration.

Author: Stefan Kolb <Stefan.Kolb@avat.de>
Date: Fri Jul 28 09:19:04 2017 -0600
We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.
The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).
The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.

STM32 F7 Ethernet: Fix typo in header; Add memory sync barrier between writing to DMA TX descriptor and restarting DMA TX. Avoid calling work_queue on pollwork if it's already queued, just skip a poll cycle instead. Nucleo-144: Fix RMII TXD1 signal, connected to PB13 not to PG14.

I was having issues with the bus freezing up .. slaves holding SDL low.. so I rewrote a good portion of the interrupt logic based on the application notes from Atmel. One major improvement is using the RXNACK flag in the STATUS register, which indicates that no device responded to an address packet. Assuming that the chip will always give an interrupt status, I believe it's possible to eliminate the timer as well.

In arch/arm/src/stm32/Kconfig when the CPU is a STM32F4, some STM32_HAVE_xx with xx = {OTGFS, TIM3, TIM4, SPI3, I2S3, I2C3} are selected by default. But for F410 these peripherals are absent. This change add tests to check if the target CPU is an F410 or not and selects according to the situation. This also adds a select for STM32_HAVE_DAC1 present on this STM32 flavor.
