2019-02-12enetc: add PTP clock driverYangbo Lu4-2/+162
This patch is to add PTP clock driver for ENETC. The driver reused QorIQ PTP clock driver. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-12ptp: add QorIQ PTP support for ENETCYangbo Lu1-1/+1
This patch is to add QorIQ PTP support for ENETC. ENETC PTP driver which is a PCI driver for same 1588 timer IP block will reuse QorIQ PTP driver. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-12ptp_qoriq: fix register memory mapYangbo Lu2-14/+15
The 1588 timer on eTSEC Ethernet controller uses different register memory map with DPAA Ethernet controller. Now the new ENETC Ethernet controller uses same reigster memory map with DPAA. To support ENETC, let's use register memory map of DPAA/ENETC in default. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-12dt-binding: ptp_qoriq: add little-endian supportYangbo Lu1-0/+3
Specify "little-endian" property if the 1588 timer IP block is little-endian mode. The default endian mode is big-endian. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-12ptp_qoriq: add little enadian supportYangbo Lu3-42/+60
There is QorIQ 1588 timer IP block on the new ENETC Ethernet controller. However it uses little endian mode which is different with before. This patch is to add little endian support for the driver by using "little-endian" dts node property. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Moved QorIQ PTP clock initialization/free into new functions ptp_qoriq_init()/ptp_qoriq_free(). These functions could also be reused by ENETC PTP drvier which is a PCI driver for same 1588 timer IP block. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S.

2019-02-12ptp_qoriq: make ptp operations globalYangbo Lu2-11/+25

2019-02-12ptp_qoriq: make structure/function names more consistentYangbo Lu5-171/+171
Strings containing "ptp_qoriq" or "qoriq_ptp" which were used for structure/function names were complained by users. Let's just use the unique "ptp_qoriq" to make these names more consistent. This patch is just to unify the names using "ptp_qoriq". It hasn't changed any functions. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-12net/skbuff: fix up kernel-doc placementBrian Norris1-6/+6
There are several skb_* functions where the locked and unlocked functions are confusingly documented. For several of them, the kernel-doc for the unlocked version is placed above the locked version, which to the casual reader makes it seems like the locked version "takes no locks and you must therefore hold required locks before calling it." One can see, for example, that this link claims to document skb_queue_head(), while instead describing __skb_queue_head(). https://www.kernel.org/doc/html/latest/networking/kapi.html#c.skb_queue_head The correct documentation for skb_queue_head() is also included further down the page. This diff tested via: $ scripts/kernel-doc -rst include/linux/skbuff.h net/core/skbuff.c No new warnings were seen, and the output makes a little more sense.

2019-02-12net/tls: Do not use async crypto for non-data recordsVakul Garg1-6/+12
Addition of tls1.3 support broke tls1.2 handshake when async crypto accelerator is used. This is because the record type for non-data records is not propagated to user application. Also when async decryption happens, the decryption does not stop when two different types of records get dequeued and submitted for decryption. To address it, we decrypt tls1.2 non-data records in synchronous way. We check whether the record we just processed has same type as the previous one before checking for async condition and jumping to dequeue next record.

Christoph Hellwig says: ==================== net: don't pass a NULL struct device to DMA API functions v2 We still have a few drivers which pass a NULL struct device pointer to DMA API functions, which generally is a bad idea as the API implementations rely on the device not only for ops selection, but also the dma mask and various other attributes. This series contains all easy conversions to pass a struct device, besides that there also is some arch code that needs separate handling, a driver that should not use the DMA API at all, and one that is a complete basket case to be deal with separately. Changes since v1: - fix an inverted ifdef in CAIF - update the smc911x changelog - split the series, this only contains the networking patches ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-12smc911x: pass struct device to DMA API functionsChristoph Hellwig1-2/+2
The DMA API generally relies on a struct device to work properly, and only barely works without one for legacy reasons. Pass the easily available struct device from the platform_device to remedy this. Note that smc911x apparently is a PIO chip with an external DMA handshake, and we probably use the wrong device here. But at least it matches the mapping side, which apparently works or at least worked in the not too distant past. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S.
