Using %4s to format f->fmt.pix_mp.pixelformat in fdp1_try_fmt() and fdp1_s_fmt() may lead to more characters being printed (when the byte following field pixelformat is not zero). Add ".4" to the format specifier to limit the number of printed characters to four. The resulting format specifier "%4.4s" is also used by other media drivers to print pixelformat value.

Marcel Hasler authored
The STK1160 needs some time to transfer data to and from the AC97 codec. The transfer completion is indicated by command read/write bits in the chip's audio control register. The driver should poll these bits and wait until they have been cleared by hardware before trying to retrieve the results of a read operation or setting a new write command.

Marcel Hasler authored
Some STK1160-based devices use the chip's internal 8-bit ADC. This is configured through a strap pin. The value of this and other pins can be read through the POSVA register. If the internal ADC is used, or if audio is disabled altogether, there's no point trying to setup the AC97 codec. Signed-off-by:

Marcel Hasler authored
Exposing all the channels of the device's internal AC97 codec to userspace is unnecessary and confusing. Instead the driver should setup the codec with proper values. This patch removes the mixer and sets up the codec using optimal values, i.e. the same values set by the Windows driver. This also makes the device work out-of-the-box, without the need for the user to reconfigure the device every time it's plugged in. Signed-off-by:

Originally Toshiba told us that the only way to disable HDCP was to set the receiver in repeater mode, that would make the authentication fail because of missing software support. It has worked fine with all the sources we and our customers has used, until it was reported problems with Apple MacBook (Retina, 12-inch, Early 2015) (https://support.apple.com/kb/SP712?locale=en_US&viewlocale=en_US) with Apple A1612 USB type-C multiport adapter (http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter) Finally Toshiba came up with a hidden bit that is named "Manual HDCP authentication". In this patch the original "repeater mode" concept is removed, and the new bit is set instead. With his patch HDCP is disabled when connected to the Apple MacBook and all other sources we have tested so far. The Apple MacBook is constantly trying to authenticate, but fails and continues to transmit unencrypted video. Signed-off-by:

The number of CSI lanes that should be used is set to the CSI_CONTROL register by indirectly writing to the CSI_CONFW register. When the number of lanes is read back from the CSI_CONTROL register the value is usually correct, but we have seen that it suddenly is 1 for a short moment before the correct value is restored again. Toshiba have not figured out why that happen, but we have found it safer to store the value in the driver. Signed-off-by:

dib7000p_read_word() may return zero on i2c errors, resulting in dib7000p_get_internal_freq() returning zero. So don't divide by the result of dib7000p_get_internal_freq() without checking it for zero in dib7000p_set_dds(). On one of my machines the device ID 2304:0229 Pinnacle Systems, Inc. PCTV Dual DVB-T 2001e about once a day/every two days gets into a state, where most (all?) I2C reads return with an error. Tuning during this state will result in a divide by zero without this patch. This patch doesn't fix the root cause for the device getting into a bad state, but it allows me to unload/reload the drivers, bringing it back into a usable state. Signed-off-by:

In asds configured with V4L2_ASYNC_MATCH_OF, the v4l2 subdev can be part of a devicetree overlay, for example: &media_bridge { ... my_port: port@0 { #address-cells = <1>; #size-cells = <0>; reg = <0>; ep: endpoint@0 { remote-endpoint = <&camera0>; }; }; }; / { fragment@0 { target = <&i2c0>; __overlay__ { my_cam { compatible = "foo,bar"; port { camera0: endpoint { remote-endpoint = <&my_port>; ... }; }; }; }; }; }; Each time the overlay is applied, its of_node pointer will be different. We are not interested in matching the pointer, what we want to match is that the path is the one we are expecting. Change to use of_node_cmp() so that we continue matching after the overlay has been removed and reapplied.
