2014-06-20can: dev: let can_get_echo_skb() return dlc of CAN frameMarc Kleine-Budde
can_get_echo_skb() is usually called in the TX complete handler. The stats->tx_packets and stats->tx_bytes should be updated there, too. This patch simplifies to figure out the size of the sent CAN frame. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
2014-01-27input: touchscreen: added platform data for Fusion touchscreenStefan Agner
Added platform data struct to define interrupt and reset GPIO. This allows to initialize the touchscreen controller inside the driver rather then in each platform and use the driver as a module.
2013-11-05mvf_adc: support all 32 channelsStefan Agner
Enable support for all 32 ADC channels, even the internal one. This is needed to read out the internal temperature since the sensor is at channel 26.
2013-11-05mvf_adc: fix register configuration in adc_setStefan Agner
Several registers in adc_set were set logical inverse or even the wrong bits in the registers. Also, return the users ioctrl if the configuration is not valid.

2013-10-02colibri-vf50-ts/mvf-adc: Moved touchscreen support in a moduleStefan Agner
The touchscreen support backed by hardware on the Colibri VF50 module and the Vybrid ADC is now moved to a own module for better maintainability. The mvf-adc driver exports some of its method now. A good good locking mechanism is still missing.

2012-03-01mmc: queue: let host controllers specify maximum discard timeoutAdrian Hunter
Some host controllers will not operate without a hardware timeout that is limited in value. However large discards require large timeouts, so there needs to be a way to specify the maximum discard size. A host controller driver may now specify the maximum discard timeout possible so that max_discard_sectors can be calculated. However, for eMMC when the High Capacity Erase Group Size is not in use, the timeout calculation depends on clock rate which may change. For that case Preferred Erase Size is used instead.

2012-03-01mmc: block: allow get_card_status() to return error statusRussell King - ARM Linux
If the MMC_SEND_STATUS command is not successful, we should not return a zero status word, but instead allow the caller to know positively that an error occurred.

2012-03-01mmc: core: add non-blocking mmc request functionPer Forlin
Previously there has only been one function mmc_wait_for_req() to start and wait for a request. This patch adds: * mmc_start_req() - starts a request wihtout waiting If there is on ongoing request wait for completion of that request and start the new one and return. Does not wait for the new command to complete. This patch also adds new function members in struct mmc_host_ops only called from core.c: * pre_req - asks the host driver to prepare for the next job * post_req - asks the host driver to clean up after a completed job The intention is to use pre_req() and post_req() to do cache maintenance while a request is active. pre_req() can be called while a request is active to minimize latency to start next job. post_req() can be used after the next job is started to clean up the request. This will minimize the host driver request end latency. post_req() is typically used before ending the block request and handing over the buffer to the block layer. Add a host-private member in mmc_data to be used by pre_req to mark the data. The host driver will then check this mark to see if the data is prepared or not.

Add functionality to parse Audio Data Blocks from EDID data to find out what modes of LPCM are suppored by the HDMI sink device. The parsed settings are saved in the hdmi mfd. The HDMI audio driver will check the settings when the audio stream is opened and will then apply appropriate constraints. If we are unable to read from the EDID, then we default to supporting Basic Audio as defined by the HDMI specification (stereo, 16 bit, 32KHz, 44.1KHz, 48KHz PCM).
