* Fix SPI so that SPI4 Clock will not be 2 times requestedDavid Sidrane2015-02-131-3/+3
| | | | | | | | The clocks assigned to the SPI blocks spi4 to spi6 were using the APB1 prescaler (42 mHZ) constant and should have been the APB2 prescaler (84 mHZ) constant. Thus the actual SPI clock on the bus was 2 times what is should have been (After adjustment for requested to actual) IE: Request for 11 mHz maps to an Actual 10.5 mHz but would have produced a clock of 21 mHz on the bus. This change fixes that.

* stm32-rtc: Add support for the internal low speed clock (LSI)Kevin Hester2015-01-023-15/+52
| | | | | Some boards do not have the external 32khz oscillator installed, for those boards we must fallback to the crummy internal RC clock. Turn on by defining CONFIG_RTC_LSICLOCK

* stm32_i2c: handle more error conditions on I2C busAndrew Tridgell2014-10-281-0/+28
| | | | | | | this fixes a I2C ISR storm condition where status=0x70084, which can happen with some specific types of noise on the I2C bus. This was reproduced by playing 80s rock through a Jabra wireless headset close to the I2C cables.

* stm32_i2c: handle more unexpected ISR conditionsAndrew Tridgell2014-07-121-1/+11
| | | | | | | | this clears the interrupt for more unexpected ISR conditions that otherwise lead to an ISR storm. When that happens no user threads are able to run as the I2C ISR is continually raised Thanks to Lorenz for help in tracking this down
* stm32_i2c: check for msgc underflow in I2C ISRAndrew Tridgell2014-07-121-17/+24
| | | | | | a spurious I2C interrupt could cause priv->msgc to underflow, leading to memory being overwritten. This seems to have been the cause of at least some of lockups we have seen
* stm32_i2c: ensure we don't change priv-> after semaphore is releasedAndrew Tridgell2014-07-121-1/+2
| | | | | | | this prevents a race condition where a subsequent I2C transfer could be lost Many thanks to hxxnrx@gmail.com for reporting this bug

* stm32: add sw workaround for broken stm32 hw RTS implementationKevin Hester2014-05-201-5/+97
| | | | | | | | | | | | | | adds support for manually asserting nRTS when the OS buffer is nearly full and deasserting it when it has room again. This makes the RTS pin actually work in a useful way (the stm32 hw implementation is broken - it asserts nRTS as soon as more than one character is received). We assert nRTS from inside of up_recvchars. For deassertion we needed a new callback from the general serial device layer when characters have been dequed. onrxdeque was added to uart_ops_s for this purpose and implemented (currently) only on the stm32.
* Revert "stm32_i2c: ensure that unexpected ISR can't overwrite stale data"Lorenz Meier2014-05-141-10/+1
| | | | | | This reverts commit 099b2017ccfa0fc7696f168db2a0c2e13fe5edbc. This is only a temporary measure to gain the time to apply a more complete fix without side effects.

| |/ |/| | | | | | | | | | | | | if we get an ISR leftover from a previous read transfer it could use stale values for priv->dcnt and priv->ptr to overwrite stack that is no longer in scope. This resets dcnt and ptr on each new stm32_i2c_process() call to ensure that any unexpected data bytes are discarded
