The existence of the network driver ioctl() method should depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. The former enables the method, the later enables a subset of possible driver IOCTLs. This change should be basically a no-operation. The affected ioctl methods only support those subset of driver IOCTLs selected by CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl method.

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.

Author: Stefan Kolb <Stefan.Kolb@avat.de>

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.

SAMV7: Watchdog: fix Forbidden Window Value
...
According the Datasheet the WDD Value is the lower bound of a so called Forbidden Window and to disable this we have to set the WDD
Value greater than or equal to the WDV Value. This seems to be a bug in the datasheet. It looks like we have to set it to a greater value than the WDV to realy disable this Thing. When triggering the Watchdog faster than the (very slow) clock source of the Watchdog fires, this Forbidden Window Feature resets the System if WDD equals to WDV.
This Changeset disables the Forbidden Window by setting the WDD Value to the Maximum (0xfff) Value possible.

SAMV7: MCAN: Prevent Interrupt-Flooding of ACKE when not connected to CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node acknowledges the message sent. This will also occur if the device is not connected to the can-bus. The CAN-Standard declares, that the Chip has to retry a given message as long as it is not sent successfully (or it is not cancelled by the application). Every time the chip tries to resend the message an Acknowledge-Error-Interrupt is generated. At high baud rates this can lead in extremely high CPU load just for handling the interrupts (and possibly the error handling in the application). To prevent this Interrupt-Flooding we disable the ACKE once it is seen as long we didn't transfer at least one message successfully.

SAMV7 USBDEVHS: A problem occurred if the USB cable is unplugged while a large amount of data is send over an IN endpoint using DMA. If the USB cable is plugged in again after a few seconds it is not possible to send data over this IN endpoint again, all other endpoints work as expected.
...
The problem occurs because if the USB cable is unplugged while an DMA transfer is in flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL is left in an undefined state. The problem was fixed the problem by resetting the register SAM_USBHS_DEVDMACTRL to a known state. Additionally all pending interrupts are cleared.

This commit solves a problem which causes data loss while sending data via USB. This problem is caused by an incorrect handling of the endpoint state in the USB driver sam_usbdevhs. This leads under some circumstances to situations in which an DMA transfer is setup while a previous DMA transfer is currently active. Amongst other things I introduced the new endpoint state USBHS_EPSTATE_SENDING_DMA for the fix.
...
To reproduce the problem, I used a program which send as many data as possible via a CDC/ACM device and verified the received data on the PC.

TWIHS Driver improved and GPIO-Driver fixed for Open-Drain Pins
...
- sam_gpioread: Now the actual line level from the pin is read back. This is extremely important for Open-Drain Pins, which can be used bidirectionally
- Re-Implemented twi_reset-function and enhanced it so it can be called from inside the driver (see next point)
- Glitch-Filter: Added a configuration option to enable the twi-built-in glitch filter
- Added a "Single Master Mode": In EMC Testing the TWI-Bus got stuck because the TWI-Master detected a Multi-Master access (but there is no second master). With the option "Single Master" we detect these events and automatically trigger a twi_reset. We also do an automatic recovery if a slave got stuck (SDA stays low).
With the above changes I²C-Bus reliability in harsh environments (eg. EMC) is greatly improved.
The small change in the GPIO-Driver was necessary because otherwise you cannot read back the correct line status of Open-Drain Outputs and this is needed by the twi_reset function.

hen configuring a GPIO via stm32_configgpio() the function will first set the mode to output and then set the initial state of the gpio later on. If you have an application with an externaly pulled-up pin, this would lead to a glitch on the line that may be dangerous in some applications (e.G. Reset Line for other chips, etc). This changes sets the output state before configuring the pin as an output.

* SAMV7: SPI: SPI-Freq. 40MHz; VARSELECT; hw-features
...
This change adds the following improvements:
- Increase the allowed SPI-Frequency from 20 to 40 MHz.
- Correct and rename the "VARSELECT" option This option was included in the code as "CONFIG_SPI_VARSELECT" but nowhere defined in a Kconfig file. The patch renames it to "CONFIG_SAMV7_SPI_VARSELECT" and corrects the implementation according the datasheet of Atmel. In short, this option switches the processor from "fixed peripheral selection" (single device) to "variable peripheral selection" (multiple devices on the bus).
- Add a new Function to the interface to control the timing and delays of the chip according the ChipSelect lines. This function can control the delay between the assertion of the ChipSelect and the first bit, between the last bit and the de-assertion of the ChipSelect and between two ChipSelects. This is needed to tune the transfer according the specification of the connected devices.
- Add three "hw-features" for the SAMV7, which controls the behavior of the ChipSelect:
1. force CS inactive after transfer: this forces a (short) de-assertion of the CS after a transfer, even if more data is
available in time
2. force CS active after transfer: this forces the CS to stay active after a transfer, even if the chip runs out of data. Btw.: this is a prerequisit to make the LASTXFER bit working at all.
- escape LASTXFER: this suppresses the LASTXFER bit at the end of the next transfer. The "escape"-Flag is reset automatically.

Cosmetic fix to spacing
2016-05-29 08:25:05 -06:00

This is a fix to a problem in the handling of the oneshot timer. Due to a wrong assumption concerning the behavior directly after the start of the timer/counter the function sam_oneshot_cancel(…) calculates the wrong remaining time. The code assumes that the counter register is zero directly after the start of the timer, but this is not true. To start the time/counter a software trigger is invoked, this trigger starts the timer/count and sets the counter register to zero, but the reset of the counter register is not performed instantly. According to the datasheet: “The counter can be reset by a trigger. In this case, the counter value passes to zero on the next valid edge of the selected clock.” Thus the counter is set to zero between 0 and USEC_PER_TICK microseconds after the clock was started.
...
In my fix I use the freerun count value to determine if at least one tick passed since the start of the timer and thus if the value of the oneshot counter is correct. I also tried to use the function up_timer_gettime(…) to achieve this but, at least if compiled with no optimization the problem vanishes without using the value of the function, the function call takes too long.
Another problem treated in the fix is that if the oneshot timer/counter is canceled, we only know the remaining time with a precision of USEC_PER_TICK microseconds. This means the calculated remaining time is between 0 and USEC_PER_TICK microseconds too long. To fix this I subtract one tick if the calculated remaining time is greater than one tick and otherwise set the remaining time to zero. By doing so the measured times are much more precise as without it.

SAMV7: USBHS: Remove disabling of whole usb on suspend
...
This fix removes the disabling of the whole USB peripheral on suspend
interrupt. Its enough to freeze the clock instead.
When disabling the whole peripheral, the next wakeup-interrupt comes
up with an disabled clocking. The unfreeze clock has no effect, because
the master clock is disabled. This makes all registers, including the
IDR unwriteable and the IRQ falls in an endless loop blocking the whole
system.
Furthermore the disabling of the peripheral clock prevents hotplugging
or reconnecting the USB.

Add the up_systemreset interface to the samv7 arch. The approach is slightly different in that: 1) It enables ARCH_HAVE_RESET and allows the user to set if, and for how long, to drive External nRST signal. It also does not contain a default board_reset, as that really should be done in the config's src if CONFIG_BOARDCTL_RESET is defined.

I found this a while back in the stm32 family, so there may be more arch-es with this sort of bug. I suppose any driver that has the notion of "do not set the freq if it is already set" could be suspect.

The thing I did not add is warning or compilation failure, (to save the next guy the hassle), at ALL the driver points that uses the these pins.
I did remove this

* instead of TDI
*/
uint32_t sysioreg = getreg32(SAM_MATRIX_CCFG_SYSIO);
sysioreg |= MATRIX_CCFG_SYSIO_SYSIO4;
putreg32(sysioreg, SAM_MATRIX_CCFG_SYSIO);
in sam_lowputc.c in favor of an #error - because the default is an input TDI and driving it blindly to an output TXD1, would be a contention.

SAMV7 MCAN: use FIFO mode instead of QUEUE mode; improve error reporting
...
When using QUEUE mode sometimes the counting semaphore indicates there is no space left in the TX buffers, but in fact there is. This leads to a situation, where all TX buffers are empty and the driver
still waits for space in the buffers. The switch from QUEUE mode to FIFO mode is just a workarround to make the semaphore counting self repairing.
The Error reporting is changed due to some Error Interrupts not reporting states, they are reporting state changes. To keep this into Account the static Error conditions like WARNING, PASSIVE or BUS_OFF are filled in
every time.
