2014-07-29can: flexcan: flexcan_chip_start: fix regression, mark one MB for TX and ↵Colibri_VF_LinuxImageV2.3Beta1_20140804Marc Kleine-Budde
abort pending TX In patch 0d1862e can: flexcan: fix flexcan_chip_start() on imx6 the loop in flexcan_chip_start() that iterates over all mailboxes after the soft reset of the CAN core was removed. This loop put all mailboxes (even the ones marked as reserved 1...7) into EMPTY/INACTIVE mode. On mailboxes 8...63, this aborts any pending TX messages. After a cold boot there is random garbage in the mailboxes, which leads to spontaneous transmit of CAN frames during first activation. Further if the interface was disabled with a pending message (usually due to an error condition on the CAN bus), this message is retransmitted after enabling the interface again. This patch fixes the regression by: 1) Limiting the maximum number of used mailboxes to 8, 0...7 are used by the RX FIFO, 8 is used by TX. 2) Marking the TX mailbox as EMPTY/INACTIVE, so that any pending TX of that mailbox is aborted.

2014-07-11can: flexcan: add Vybrid supportStefan Agner
Extend FlexCAN driver to support Vybrid. Vybrids variant of the IP has ECC support which is controlled through the memory error control register (MECR). There is also an errata which leads to false positive error detections (ID e5295). This patch disables the memory error detection completely. Extend the clock control for FlexCAN to enable the clocks. Fix the base addresses and introduce the necessary pinmux defines.
2014-07-11can: flexcan: dynamically sleep for chip_{en,dis}ableStefan Agner
In flexcan_chip_enable() and flexcan_chip_disable() fixed delays are used. Experiments have shown that the transition from and to low power mode may take several microseconds. This patch adds a while loop which polls the Low Power Mode ACK bit (LPM_ACK) that indicates a successfull mode change. If the function runs into a timeout a error value is returned. This is a simpliefied backport of can: flexcan: fix transition from and to low power mode in chip_{en,dis}able 9b00b300e7bce032c467c36ca47fe2a776887fc2
2014-06-20can: flexcan: Fix CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACKReuben Dowle
Currently the flexcan driver uses hardware local echo. This blindly echos all transmitted frames to all receiving sockets, regardless what CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to. This patch now submits transmitted frames to be echoed in the transmit complete interrupt, preserving the reference to the sending socket. This allows the can protocol to correctly handle the local echo. Further this patch moves tx_bytes statistic accounting into the tx_complete handler.

The flexcan is still in disable mode during suspend if it's still not up. We do not need to enter stop mode if find the device is not up since the stop mode does not work well in disable mode(remote wakeup does not work). Using disable mode for suspend if it's not up.

2014-05-15colibri_vf: add support for second EthernetStefan Agner
Add alternative pinmux and platform data for second Ethernet. Also make sure MAC address is calculated from first Ethernet MAC address, which is derived from part serial number. Note that FEC1 is the default Ethernet controller (and hence eth0), while FEC0 is the additional Ethernet controller (eth1).
2014-03-06phy/micrel: Add suspend/resume support to Micrel PHYsStefan Agner
All supported Micrel PHYs implement the standard "power down" bit 11 of BMCR, so this patch adds support using the generic genphy_{suspend,resume} functions. Backported patch by Patrice Vilchez, see 1a5465f5d6a23e84ef5c06cb32f3d8c26632f42a

Various ifdefs still use CONFIG_MACH_COLIBRI_VF50. Migrate them to using the hidden CONFIG_COLIBRI_VF define active for both Colibri VF50 as well as Colibri VF61.
2013-09-10colibri_vf50: initial integrationMarcel Ziswiler
Add initial Colibri VF50 support based off Timesys' implementation for Freescale's Vybrid Tower System TWR-VF65GS10: - New machine ID. - FEC1 only. - ESDHC2 only with card detect interrupt. - PLL5 based RMII clocking (e.g. no external crystal). - VESA VGA display timing (tested with 5.7" EDT ET057090DHU). - Default UART_A on SCI0. - UART_A and UART_C I/O muxing. - I2C real time clock on carrier board. - Early boot console support. - 8-bit NAND. Tested on early Colibri VF50 prototypes V1.0a mounting root file systems both over NFS or from SD card ext3 partition.

2012-02-08Add ath6kl cleaned up driverKalle Valo
Last May we started working on cleaning up ath6kl driver which is currently in staging. The work has happened in a separate ath6kl-cleanup tree: http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary After over 1100 (!) patches we have now reached a state where I would like to start discussing about pushing the driver to the wireless trees and replacing the staging driver. The driver is now a lot smaller and looks like a proper Linux driver. The size of the driver (measured with simple wc -l) dropped from 49 kLOC to 18 kLOC and the number of the .c and .h files dropped from 107 to 22. Most importantly the number of subdirectories reduced from 26 to zero :) There are two remaining checkpatch warnings in the driver which we decided to omit for now: drivers/net/wireless/ath/ath6kl/debug.c:31: WARNING: printk() should include KERN_ facility level drivers/net/wireless/ath/ath6kl/sdio.c:527: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt The driver has endian annotations for all the hardware specific structures and there are no sparse errors. Unfortunately I don't have any big endian hardware to test that right now. We have been testing the driver both on x86 and arm platforms. The code is also compiled with sparc and parisc cross compilers. Notable missing features compared to the current staging driver are: o HCI over SDIO support o nl80211 testmode o firmware logging o suspend support Testmode, firmware logging and suspend support will be added soon. HCI over SDIO support will be more difficult as the HCI driver needs to share code with the wifi driver. This is something we need to research more. Also I want to point out the changes I did for signed endian support. As I wasn't able to find any support for signed endian annotations I decided to follow what NTFS has done and added my own. Grep for sle16 and sle32, especially from wmi.h. Various people have been working on the cleanup, the hall of fame based on number of patches is: 543 Vasanthakumar Thiagarajan 403 Raja Mani 252 Kalle Valo 16 Vivek Natarajan 12 Suraj Sumangala 3 Joe Perches 2 Jouni Malinen Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Vivek Natarajan <nataraja@qca.qualcomm.com> Signed-off-by: Suraj Sumangala <surajs@qca.qualcomm.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2012-01-31net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

On ARM one jiffy is 10ms, so use msecs_to_jiffies instead and use a timeout of 30ms, which corresponds to 3 jiffies. After running 3 hours NFS boots, the MDIO timeout do not occur anymore.

2011-12-09p54spi: Fix workqueue deadlockMichael Büsch
commit 2d1618170eb493d18f66f2ac03775409a6fb97c6 upstream. priv->work must not be synced while priv->mutex is locked, because the mutex is taken in the work handler. Move cancel_work_sync down to after the device shutdown code. This is safe, because the work handler checks fw_state and bails out early in case of a race.

2011-11-26rt2x00: Fix sleep-while-atomic bug in powersaving code.Gertjan van Wingerde
commit ed66ba472a742cd8df37d7072804b2111cdb1014 upstream. The generic powersaving code that determines after reception of a frame whether the device should go back to sleep or whether is could stay awake was calling rt2x00lib_config directly from RX tasklet context. On a number of the devices this call can actually sleep, due to having to confirm that the sleeping commands have been executed successfully. Fix this by moving the call to rt2x00lib_config to a workqueue call.

2011-11-11ath9k_hw: Fix regression of register offset for AR9003 chipsRajkumar Manoharan
commit 52d6d4ef5e6d1517688e27c11c01ab303ec681dd upstream. My recent commits (3782c69d, 324c74a) introduced regression for register offset selection that based on the macversion. Not using parentheses in proper manner for ternary operator leads to select wrong offset for the registers. This issue was observed with AR9462 chip that immediate disconnect after the association with the following message ieee80211 phy3: wlan0: Failed to send nullfunc to AP 00:23:69:12:ea:47 after 500ms, disconnecting.
