2017-09-23media: cec-gpio: add HDMI CEC GPIO driverHans Verkuil4-0/+249
Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework. While I have heard of SoCs that use the GPIO pin for CEC (apparently an early RockChip SoC used that), the main use-case of this driver is to function as a debugging tool. By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example it turns it into a CEC debugger and protocol analyzer. With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed. But of course it can also be used with any hardware project where the HDMI CEC line is hooked up to a pull-up gpio line. In addition this has (optional) support for tracing HPD changes if the HPD is connected to a GPIO.

2017-09-23media: cec: add CEC_EVENT_PIN_HPD_LOW/HIGH eventsHans Verkuil6-10/+52
Add support for two new low-level events: PIN_HPD_LOW and PIN_HPD_HIGH. This is specifically meant for use with the upcoming cec-gpio driver and makes it possible to trace when the HPD pin changes. Some HDMI sinks do strange things with the HPD and this makes it easy to debug this. Note that this also moves the initialization of a devnode mutex and list to the allocate_adapter function: if the HPD is high, then as soon as the HPD interrupt is created an interrupt occurs and cec_queue_pin_hpd_event() is called which requires that the devnode mutex and list are initialized.

CEC_TX_STATUS_ERROR can be used if the HW cannot tell LOST_ARB and LOW_DRIVE apart, or when some other error occurs. It is not a replacement for NACK.

2017-09-23media: s5p-cec: add NACK detection supportHans Verkuil3-2/+14
The s5p-cec driver returned CEC_TX_STATUS_ERROR for the NACK condition. Some digging into the datasheet uncovered the S5P_CEC_TX_STAT1 register where bit 0 indicates if the transmit was nacked or not. Use this to return the correct CEC_TX_STATUS_NACK status to userspace. This was the only driver that couldn't tell a NACK from another error, and that was very unusual. And a potential problem for applications as well. Tested with my Odroid-U3.

Josef Bacik says: ==================== net: fix reuseaddr regression I introduced a regression when reworking the fastreuse port stuff that allows bind conflicts to occur once a reuseaddr successfully opens on an existing tb.

Zerocopy skbs frags are copied when the skb is looped to a local sock. Commit 1080e512d44d ("net: orphan frags on receive") introduced calls to skb_orphan_frags to deliver_skb and __netif_receive_skb for this. With msg_zerocopy, these skbs can also exist in the tx path and thus loop from dev_queue_xmit_nit. This already calls deliver_skb in its loop. But it does not orphan before a separate pt_prev->func(). Add the missing skb_orphan_frags_rx.

2017-09-22parisc: Unbreak bootloader due to gcc-7 optimizationsHelge Deller2-2/+3
gcc-7 optimizes the byte-wise accesses of get_unaligned_le32() into word-wise accesses if the 32-bit integer output_len is declared as external. This panics then the bootloader since we don't have the unaligned access fault trap handler installed during boot time. Avoid this optimization by declaring output_len as byte-aligned and thus unbreak the bootloader code. Additionally, compile the boot code optimized for size.
